我在我的应用程序中使用XtraGrid中。我已经展示了检查列表框与列筛选唯一值。现在,我想列举这些项目进行了检查,一旦点击确定按钮后,对话框消失。如何做到这一点?
I am using XtraGrid in my application. I have shown checked list box with unique values for the column filter. Now, I want to enumerate which Items were checked once the dialog disappears after clicking OK button. How to do this?
谢谢, Omky
虽然我不知道你的检查列表框的过滤器弹出的准确实施,您可以处理 ColumnFilterChanged
事件的GridView控件。那么,我建议你分析你列的FilterCriteria,看看哪些价值被用于过滤。
While I don't know the exact implementation of your checked listbox in the filter popup, you can handle the ColumnFilterChanged
event on the GridView. Then, I suggest that you analyse the FilterCriteria of your column and see which value are being used for filtering.
private void gridView1_ColumnFilterChanged(object sender, EventArgs e)
{
var filteredValues = new List<string>();
var criteria = gridColumn1.FilterInfo.FilterCriteria;
if (criteria is GroupOperator)
{
var group = (GroupOperator)criteria;
foreach (var operand in group.Operands.OfType<BinaryOperator>())
{
var value = (OperandValue)operand.RightOperand;
filteredValues.Add(value.Value.ToString());
}
}
else if(criteria is BinaryOperator)
{
var value = (OperandValue)((BinaryOperator)criteria).RightOperand;
filteredValues.Add(value.Value.ToString());
}
// Do something with the filtered values
}
