检查RadGrid中是否存在列

Question

This is not finding the column. Anyone have any suggestions?

if (((RadGrid)sender).Columns.Contains("ClaimNumber"))
    do this...
else
    do this...

I checked the Columns Collection of the grid and I can see the column there.

Answer 1

You need to use the FindByUniqueNameSafe method:

GridColumn col = RadRadGrid1.MasterTableView.Columns.FindByUniqueNameSafe("ColumnName");
if (col != null)
{
    //column exists
}

You could also use LINQ:

if (RadGrid1.MasterTableView.Columns.Cast<GridColumn>().Count(x => x.UniqueName == "Column1") > 0)

Answer 2

if (RadGridView.MasterView.ViewTemplate.Columns.Contains("Column")){ Exist}else{ Not-Exist}
