Getting back to where I was.

[Stuart Hemming]

I have a grid with a MasterTable and a DetailTable.

There are times in the life of my app when I have the DetailTable open on a particular row of the MasterTable and I do something that requires the grid to be rebound.

I know the MasterTable row index and the row index on the DetailTable.

After I have rebound the grid, how can I get the grid to expand the relevant MasterTable row, populate the DetailTable and select the relevant row in it?

The best I could come up with is something like this...

RadGrid1.MasterTableView.Items[MasterTableRowIndex].ChildItem.Expanded = true;

Sadly this doesn't do what I thought it might.

Anyone have any clues?

Hello,

I hope the code shown below helps you in this.

C#:

 protected void RadGrid1_PreRender(object sender, EventArgs e)
    {
        // Here check for whether Rebind occurs or not
        // int rowIndex = 0;   masterTableIndex
        // int childRowIndex = 0;   Child table index
        GridDataItem masterTableItem = (GridDataItem)RadGrid1.MasterTableView.Items[rowIndex]; // Get the mastertable item
        masterTableItem.Expanded = true; // Expand the item
        masterTableItem.ChildItem.NestedTableViews[0].Items[childRowIndex].Selected = true;   // Selects the child table item
    }

[Note: you can check for whether rebind is invoked (by using any global variable, session variable etc), and execute the code to expand mastertable item and select the corresponding childitem.]


Thanks,
Princy.

Princy,

you are a, err, Prince.

It simply never occurred to me that I was trying to expand the wrong thing.

Thanks again.
