Hi ,
I want to implement google like filtering to three level hierarchy (google like filtering to second and third level grid). To implement this
i have tried following code but when i click on combo box to display filtering it displays only loading.... When i try to debug then
it dose not go to "list_ItemsRequested" function in "MyCustomFilteringColumnCS" class file.

| foreach (GridDataItem dataItem in RadGrid1.MasterTableView.Items) { |
| if (dataItem.Expanded) { |
| GridTableView gridTableView = (GridTableView)dataItem.ChildItem.NestedTableViews[0]; |
| gridTableView.Columns.Clear(); |
| foreach (DataColumn dataColumn in ds.Tables[0].Columns) |
| { |
| RadGrid.MyCustomFilteringColumn gridColumn = new RadGrid.MyCustomFilteringColumn(); |
| gridColumn.DataField = dataColumn.ColumnName; |
| gridColumn.HeaderText = dataColumn.ColumnName; |
| gridTableView.Columns.Add(gridColumn); |
| } |
| gridTableView.Rebind(); |
| } |
| } |
| } |

Hello Rahul,
Unfortunately, you cannot add columns to the nested view when RadGrid PreRender is raised, because this event is fired late in the lifecycle and hence the grid cannot persist its viewstate. For further information how to create the grid programmatically you can review this link.
In my attempt to implement your requirements, I have created a test project which is attached to this thread. My custom column is declarated in the mark-up section and the hierarchy load mode is "ServerOnDemand".
If you still need to add columns programatically, you can examine our online demo to achieve your goal. I have to note that you can add columns to the nested view only before it is bound.
