最近一直在弄第三方控件DevExpress,在gridcontol中嵌套进复选框，却只能单选，为了解决此问题在网上查了相关资料，并结合项目情况，最终得以解决

1.

ICE_selectedMark.QueryCheckStateByValue += new DevExpress.XtraEditors.Controls.QueryCheckStateByValueEventHandler(ICE_selectedMark_QueryCheckStateByValue);

2.

/// <summary>
/// 处理 RepositoryItemCheckEdit 类型的选择框多选
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
void ICE_selectedMark_QueryCheckStateByValue(object sender, DevExpress.XtraEditors.Controls.QueryCheckStateByValueEventArgs e)
{
string val = "";
if (e.Value != null)
{
val = e.Value.ToString();
}
else
{
val = "True"; //默认为选中
}
switch (val)
{
case "True":
case "Yes":
case "1":
e.CheckState = CheckState.Checked;
break;
case "False":
case "No":
case "0":
e.CheckState = CheckState.Unchecked;
break;
default:
e.CheckState = CheckState.Unchecked;
break;
}
e.Handled = true;
}
