gridControl常用属性设置

1.隐藏最上面的GroupPanel

gridView1.OptionsView.ShowGroupPanel=false;

2.得到当前选定记录某字段的值

sVal=Table.Rows[gridView1.FocusedRowHandle][FieldName].ToString();

3.数据只读

gridView1.OptionsBehavior.Editable=false;

4.不显示MasterDetailView

gridView1.OptionsDetail.EnableMasterViewMode=false;

5.修改最上面的GroupPanel内容

gridView1.GroupPanelText="柳生飘絮";

6.设置数据源:

gridControl1.DataSource = dt;

绑定每一列的FiledName--属性

对于Oracle数据库,所有的在设计器里写的程序中的字段名必须大写,否则可能绑定不上字段,sqlserver没有这个限制.

7.读写拷贝权限设置

只读不可拷贝：

ColumnViewOptionsBehavior.Editable = False

只读可拷贝:

ColumnViewOptionsBehavior.Editable = Tr

OptionsColumn.AllowEdit = Tr

OptionsColumn.ReadOnly = Tr

可编辑:

ColumnViewOptionsBehavior.Editable = Tr

OptionsColumn.AllowEdit = Tr

OptionsColumn.ReadOnly = False

8.模板列的设置:

到Columns中，在他的属性中找到ColumnEdit.

以LookUpEdit为例：

首先从Designer左边菜单In-Place Editor Repository中添加LookUpEdit.取名为Re1.然后.在他的Columns属性中添加3列.Caption依次为:编号,姓名,性别.FieldName依次为:FID,FNAME,FSEX.然后将Re1的NullText设置成空.

　　AutoSearchColumnIndex属性设置为2.ImmediatePopup属性设置为Tr.

　　SearchMode设置为OnlyInPopup.

　　然后将这个模板列附加到我们上面提到的列1(也就是将列1的ColumnEdit属性设成Re1)

　　最后我们还要在代码里面给Re1绑定数据源和显示项.

Re1.DataSource = DALUse.Qry("select fid,fname,fsex from d l").Tables[0];

Re1.DisplayMember = "FSEX";

Re1.ValMember = "FNAME";

9.设某一列文字和标题局中显示

gridView1.Columns[0].AppearanceHeader.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;

gridView1.Columns[0].AppearanceCell.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;

10.去掉某一列上面的自动筛选功能(Filter)

gridView1.Columns[0].OptionsFilter.AllowAutoFilter = false;

gridView1.Columns[0].OptionsFilter.AllowFilter = false;

gridView1.Columns[0].OptionsFilter.ImmediateUpdateAutoFilter = false;

11.设置冻结列(左冻结)

gridView1.Columns[0].Fixed= DevExpress.XtraGrid.Columns.FixedStyle.Left;

12.得到单元格数据(0行0列)

string ss=gridView1.GetRowCellDisplayText(0, gridView1.Columns[0]);

string ss = gridView1.GetRowCellVal(0, gridView1.Columns[0]);

13.设置单元格数据(将0行0列的单元格赋值123)

gridView1.SetRowCellVal(0, gridView1.Columns[0], "123");

13.手动添加dev的列

DevExpress.XtraGrid.Columns.GridColumn Col1=new DevExpress.XtraGrid.Columns.GridColumn ();

Col1.FieldName="FID";

Col1.Visible=tr;

Col1.VisibleIndex=gridView1.Columns.Count;

gridView1.Columns.Add(Col1);

14.设置自动增加的行号,需要先添加给gridview添加事件CustomDrawRowIndicator

private void gridview_CustomDrawRowIndicator(object sender,

DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e)

{

if (e.Info.IsRowIndicator && e.RowHandle >= 0)

e.Info.DisplayText = (e.RowHandle + 1).ToString();

}

15.删除: (修改了dgvdel里的datagridviewdel方法)

p lic static void datagridviewdel_Dev(DevExpress.XtraGrid.Views.Grid.GridView Mydgv)

{

if (MessageBox.Show("你确定要删除选中的记录吗？", "删除提示", MessageBoxButtons.YesNo,

MessageBoxIcon.Warning, MessageBoxDefaultButton.Button2, 0, false) == DialogResult.Yes)

{

int iSelectRowCount = Mydgv.SelectedRowsCount;

if (iSelectRowCount > 0)

{

Mydgv.DeleteSelectedRows();

}

16. 新增: (对于新增,其本身的AddNewRow方法就可以做到)

private void btn_add_Click(object sender, EventArgs e)

{

gridView1.AddNewRow();

}

具体如果对于新加行还有什么特别的设置,可以在它gridView1_InitNewRow事件中填写:

private void gridView1_InitNewRow(object sender, DevExpress.XtraGrid.Views.Grid.InitNewRowEventArgs e)

{

ColumnView View = sender as ColumnView;

View.SetRowCellVal(e.RowHandle, View.Columns[0], gridView1.GetRowCellVal(gridView1.GetRowHandle

(gridView1.RowCount - 2), gridView1.Columns[0])); //复制最后一行的数据到新行

View.SetRowCellVal(e.RowHandle, View.Columns[1], gridView1.GetRowCellVal(gridView1.GetRowHandle

(gridView1.RowCount - 2), gridView1.Columns[1])); //复制最后一行的数据到新行

}

17. 保存 (第三方控件提供的RefreshData和RefreshDataSource方法对于保存数据都不好使,最后还是使用了Dgvsave的

datagridviewsave方法,用这个方法就可以)

18.特效：gridcontrol中有5种view 型式，普通的是gridview，然后分别为cardview、BandedView、Advanced BandedView、

LayoutView；共5种。

1）、view组中把OptionView下的viewmode 设置成“Carousel”就达到这种“旋转木马”式的gridcontrol view 特效了

2）、layoutView1.OptionsCarouselMode.PitchAngle 这个属性决定“旋转木马”的pitch angle 螺距角; 螺旋角; 螺旋升角; 俯

仰角; 倾角; 节锥半角

3）、Roll Angle 属性决定着倾侧角度

4）、指定数据源，显示数据：

//显示数据

private void showData(List list)

{

DataTable dt = new DataTable("OneEmployee");

dt.Columns.Add("Caption", System.Type.GetType("System.String"));

dt.Columns.Add("Department", System.Type.GetType("System.String"));

dt.Columns.Add("PhotoName", System.Type.GetType("System.Byte[]"));

for (int i = 0; i < list.Count; i++)

{

DataRow dr = dt.NewRow();

dr["Caption"] = list[i].Name;

dr["Department"] = list[i].Department;

string imagePath = @"D:/C#/photos/" + list[i].PhotoPath;

dr["PhotoName"] = getImageByte(imagePath);

dt.Rows.Add(dr);

}

gridControl1.DataSource = dt;

}

//返回图片的字节流byte[]

private byte[] getImageByte(string imagePath)

{

FileStream files = new FileStream(imagePath, FileMode.Open);

byte[] imgByte = new byte [files.Length ];

files.Read(imgByte, 0, imgByte.Length);

files.Close();

return imgByte;

}

19.检查数据的有效性

在gridview的ValidateRow事件中加入检查代码：

#region 检查数据

private void gridView1_ValidateRow(object sender, ValidateRowEventArgs e)

{

GridView view = sender as GridView;

view.ClearColumnErrors();

if (view.GetRowCellVal(e.RowHandle, "ReceiveDate") == DBNull.Val)

{

e.Valid = false;

view.SetColumnError(view.Columns["ReceiveDate"], "必须指定日期");

}

#endregion

调用gridview.UpdateCurrentRow()方法执行检查

最常用的DevExpress Winform 4个代码片段：

一、GridControl的删除操作

private void rILinkEditInfoDel_Click(object sender, EventArgs e)

{

if (XtraMessageBox.Show("请确定是否删除当前记录？", "警告", MessageBoxButtons.YesNo, MessageBoxIcon.Warning) == DialogResult.Yes)

{

DataRow row = gvInfos.GetDataRow(gvInfos.FocusedRowHandle);

delByCode(row["Code"].ToString());

XtraMessageBox.Show("操作成功！");

}

二、绑定非数据表中列

Hashtable ht = new Hashtable();

private void gridView6_CustomUnboundColumnData(object sender, DevExpress.XtraGrid.Views.Base.CustomColumnDataEventArgs e)

{

GridView View = sender as GridView;

if (e.RowHandle >= 0)

{

object needAlert = View.GetRowCellVal(e.RowHandle, View.Columns["needAlert"]);

if (needAlert != null & needAlert != DBNull.Val && needAlert.ToString().Trim() != "0" & View.GetRowCellVal(e.RowHandle, View.Columns["Val"]) != DBNull.Val)

{

decimal AverVal = Convert.ToDecimal(View.GetRowCellVal(e.RowHandle, View.Columns["Val"]));

object MinVal = View.GetRowCellVal(e.RowHandle, View.Columns["MinVal"]);

object MaxVla = View.GetRowCellVal(e.RowHandle, View.Columns["MaxVal"]);

if (MinVal != DBNull.Val & MinVal != null & MaxVla.ToString() != "" & MaxVla != DBNull.Val && MaxVla != null & MaxVla.ToString() != "")

{

decimal gridColumn2 = Convert.ToDecimal(View.GetRowCellVal(e.RowHandle, View.Columns["MinVal"]));

decimal gridColumn1 = Convert.ToDecimal(View.GetRowCellVal(e.RowHandle, View.Columns["MaxVal"]));

if (gridColumn2 > AverVal || AverVal > gridColumn1)

{

if (!ht.ContainsKey("pic"))

ht.Add("pic", GetImage(1));

e.Val = ht["pic"];

}

///

/// 由资源文件获取图片

///

byte[] GetImage(int key)

{

Image img = DevExpress.Utils.Controls.ImageHelper.CreateImageFromResources(string.Format("RiverSys.Resources.{0}.gif", key.ToString()), typeof(RiverInfos).Assembly);

return DevExpress.XtraEditors.Controls.ByteImageConverter.ToByteArray(img, ImageFormat.Gif);

}

///

/// 动态根据条件设置行样式

///

private void gridView6_RowStyle(object sender, DevExpress.XtraGrid.Views.Grid.RowStyleEventArgs e)

{

GridView View = sender as GridView;

if (e.RowHandle >= 0)

{

object needAlert = View.GetRowCellVal(e.RowHandle, View.Columns["needAlert"]);

if (needAlert != null & needAlert != DBNull.Val && needAlert.ToString().Trim() != "0" & View.GetRowCellVal(e.RowHandle, View.Columns["Val"]) != DBNull.Val)

{

decimal AverVal = Convert.ToDecimal(View.GetRowCellVal(e.RowHandle, View.Columns["Val"]));

object MinVal = View.GetRowCellVal(e.RowHandle, View.Columns["MinVal"]);

object MaxVla = View.GetRowCellVal(e.RowHandle, View.Columns["MaxVal"]);

if (MinVal != DBNull.Val & MinVal != null & MaxVla.ToString() != "" & MaxVla != DBNull.Val && MaxVla != null & MaxVla.ToString() != "")

{

decimal gridColumn2 = Convert.ToDecimal(MinVal);

decimal gridColumn1 = Convert.ToDecimal(MaxVla);

if (gridColumn2 > AverVal || AverVal > gridColumn1)

{

e.Appearance.ForeColor = Color.Red;

e.Appearance.BackColor = Color.LightGray;

}

三、GridControl 中颜色选择控件

private void gvMapColor_CustomUnboundColumnData(object sender, DevExpress.XtraGrid.Views.Base.CustomColumnDataEventArgs e)

{

GridView view = sender as GridView;

DataView dv = view.DataSource as DataView;

if (e.IsGetData)

{

string strVal = dv[e.ListSourceRowIndex]["Color"].ToString();

if (strVal != "")

{

//e.Val = DevExpress.Utils.StyleLayout.ColorFromString(strVal);

e.Val = Common.HexToColor(strVal);

}

else

{

//Color colorVal = DevExpress.Utils.StyleLayout.ColorFromString(e.Val.ToString());

Color colorVal = (Color)e.Val;

dv[e.ListSourceRowIndex]["Color"] = Common.RGB_HEX(colorVal.ToArgb());

}

四、关于 GridControl 验证示例

///

/// 初始化GridView，绑定数据

///

private void GridViewBindData(string parentId)

{

this.gridView1.Columns.Clear();

this.FDs= areaSetupActionHelper.getDsRegionByParentId(parentId);

this.gridCArea.DataSource =this.FDs.Tables[0].DefaultView;

this.gridView1.Columns["id"].VisibleIndex = -1;

this.gridView1.Columns["childCounts"].VisibleIndex = -1;

this.gridView1.Columns["reg_id"].Caption = "区划编号";

this.gridView1.Columns["reg_name"].Caption = "区划名称";

this.gridView1.Columns["parent_id"].Caption = "父区划编号";

this.gridView1.Columns["reg_desc"].Caption = "区划描述";

this.gridView1.Columns["parent_id"].ImageIndex =1;

this.gridView1.Columns["reg_desc"].ImageIndex = 0;

RepositoryItemTextEdit textEditReg_Id = new RepositoryItemTextEdit();

textEditReg_Id.Mask.EditMask =parentId+"//d{2,3}";

textEditReg_Id.Mask.MaskType = DevExpress.XtraEditors.Mask.MaskType.Regular;

this.gridView1.Columns["reg_id"].ColumnEdit = textEditReg_Id;

this.gridView1.Columns["reg_desc"].ColumnEdit = new RepositoryItemMemoExEdit();

TreeListNode node = this.treelArea.FocusedNode.ParentNode;

string fid = node==null?"0":node.GetVal("RegID").ToString().Trim();

DataSet ds = areaSetupActionHelper.getDsRegionByParentId(fid);

RepositoryItemLookUpEdit lookParent_Id = new RepositoryItemLookUpEdit();

lookParent_Id.Columns.Add(new LookUpColumnInfo("reg_id", 40, "区划编号"));

lookParent_Id.Columns.Add(new LookUpColumnInfo("reg_name", 40, "区划名称"));

lookParent_Id.DataSource = ds.Tables[0].DefaultView;

lookParent_Id.ValMember = "reg_id";

lookParent_Id.DisplayMember = "reg_id";

this.gridView1.Columns["parent_id"].ColumnEdit = lookParent_Id;

}

///

/// gridView单元格验证的相关处理程序

///

private void gridView1_ValidatingEditor(object sender, DevExpress.XtraEditors.Controls.BaseContainerValidateEditorEventArgs e)

{

if (e.Valid == false&this.gridView1.FocusedColumn.FieldName == "reg_id")

{

e.ErrorText = "区划编号不合法！/n应为父区划编号加2～3位数据组成！";

}

if (this.gridView1.FocusedColumn.FieldName == "reg_name")

{

Regex reg=new Regex(@"[/一-/龥]{1,20}");

Match m=reg.Match(e.Val.ToString().Trim());

if (m.Length != e.Val.ToString().Trim().Length)

{

e.Valid = false;

e.ErrorText = "区划名称应为汉字/n长度为1至20";

}

private void gridView1_InvalidValException(object sender, InvalidValExceptionEventArgs e)

{

if (MyDialog.Alert("　您所填写的内容不符合规则/n　要放弃您刚才对此项所做的更改吗？", "您所编辑的内容不符合规则", MessageBoxButtons.YesNo, MessageBoxIcon.Warning) == DialogResult.Yes)

{

e.ExceptionMode = ExceptionMode.Ignore;

}

///

/// gridView行验证的相关处理程序

///

private void gridView1_ValidateRow(object sender, DevExpress.XtraGrid.Views.Base.ValidateRowEventArgs e)

{

string regid = this.gridView1.GetRowCellVal(e.RowHandle, "reg_id").ToString().Trim();

string regName = this.gridView1.GetRowCellVal(e.RowHandle, "reg_name").ToString().Trim();

if ( regid.Length < 1)

{

e.Valid = false;

this.gridView1.SetColumnError(this.gridView1.Columns["reg_id"], "请填写区划编号!", DevExpress.XtraEditors.DXErrorProvider.ErrorType.Default);

// e.ErrorText = "区划名称不能为空!";

}

if (regName.Length < 1)

{

e.Valid = false;

this.gridView1.SetColumnError(this.gridView1.Columns["reg_name"], "区划名称不能为空!", DevExpress.XtraEditors.DXErrorProvider.ErrorType.Default);

学习XtraGrid

1.基本grid的用法

1.1 gridControl-->view-->gridView

绑定到grid上的字段可以拖动删除，在任意字段上右键点column chooser 可以将删除的字段添加进来

字段上右键选择实现选定需要的信息和排序

字段上右键选择分组(group by column)，也可以直接将字段拖到上面实现分组

字段上右键选择group by box后可以取消分组栏，（不能实现拖动分组，但可以选择分组）

字段上右键选择best fit可以实现该字段最佳宽度（便于查看）

1.2 gridControl-->view-->cardView

以卡片形式存放数据

可以自己设定过滤选项

1.3 gridControl-->view-->banderGridView

将字段分段显示，前提是给gridControl先绑定一个dataset

动态绑定的时候不能分段，也不能分行

1.3 gridControl-->view-->advBanderGridView

高级分段显示，动态绑定的字段可以在前台向下拖动后分段，但效果不好，相当于分行显示的样子

1.4 else

可以通过create ner view增加一个view ，但程序只显示你选定的view

zoom的使用快速上升，也就是选择子项后单独显示（上到最高显示）

1.5 feature browser

-->priview 可以指定在每行中预览的字段

-->filtering 可以自动过滤（optingview.showAutoFiterRow）

1.7 Master-Detail 绑定的问题
首先在gridControl1中指定dataSource 的绑定是主表
然后在level设计器中添加层（retrieve details）
最后用代码绑定：
using (SqlConnection con = new SqlConnection(SqlHepler.CONN_STRING))
            {
                //SqlDataAdapter sda1 = new SqlDataAdapter("select * from Orders",con);
                //sda1.Fill(this.northwindDataSet.Orders);

                SqlDataAdapter sda2 = new SqlDataAdapter("select * from [Order Details]",con);
                sda2.Fill(this.northwindDataSet.Order_Details);
            }

1.8 summary的用法

            //If the GridOptionsView.ShowFooter option is set,
            //the summary(of course some else can ) can be displayed within the footer cell.
            gridView1.OptionsView.ShowFooter = true;

            //初始化，也可以不用指定
            colOrderID.SummaryItem.FieldName = "OrderID";
            colOrderID.SummaryItem.SummaryType = DevExpress.Data.SummaryItemType.Count;

2.XtraGrid的打印

借用别人写的一个类

class DevPrint
{

        //*********************字段*********************
        private string pageHeaderName="";
        private string pageFooterName="";
        private bool isPrintPage=true;
        private bool isPrintDate=true;
        private int headerLocation=1;
        private int footerLocation=1;
        private int pageLocation=3;
        private int dateLocation=5;
        private bool enableEditPage = true;
        private System.Drawing.Font pageHeaderFont = null;
        private System.Drawing.Font pageFooterFont = null;
        private System.Drawing.Printing.Margins devMargins = null;
        private System.Drawing.Printing.PaperKind devPaperKind = System.Drawing.Printing.PaperKind.A4;//可以自定义修改纸张
        private DevExpress.XtraPrinting.PageHeaderArea PHA = new DevExpress.XtraPrinting.PageHeaderArea();
        private DevExpress.XtraPrinting.PageFooterArea PFA = new DevExpress.XtraPrinting.PageFooterArea();
        //*********************字段*********************

        //*********************属性*********************
        //标题
        public string PageHeaderName

           }
           set
