[Solved] How to Access GridGroupSplitterColumn

[Marcus]

Hi there,

I have a grouping grid and would like to insert something in the - I believe it would be the GridGroupSplitterColumn - of the individual items. I do not want to replace the Expand/Collapse images - I would like to use the space in the automatically created cell underneath the Expand/Collapse images (am I making sense here?)

Is this possible? Can someone point me in the right direction?
Thx in advance!

Hello Marcus,

I tried following code in order to add insert text in the space in the created underneath the Expand/Collapse images when using grouping.

C#:

    protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if (e.Item.OwnerTableView.IsItemInserted && e.Item is GridPagerItem)
        {
            GridPagerItem pagerItem = (GridPagerItem)e.Item;
            pagerItem.Display = false;
        }
        if (e.Item is GridDataItem)
        {
            GridDataItem item = (GridDataItem)e.Item;

            if (RadGrid1.MasterTableView.GroupByExpressions.Count > 0)
            {
                TableCell cell = (TableCell)item["column"];
                Label lbl = new Label();
                lbl.Text = "Hai";
                cell.Controls.Add(lbl);
            }
        }
    }

Hi Shinu,
many thanks for your reply, but I'm afraid I don't quite understand your code. You have a named column "column" in there. What are you referencing there? As far as I know the SplitterColumn doesn't have a name - or does it?

Thx again!

Hello Marcus,

I tried following code in ColumnCreated event to get the ColumnUniqueName of GridGroupSplitterColumn.

C#:

public string un = "";

protected void RadGrid1_ColumnCreated(object sender, GridColumnCreatedEventArgs e)

{

if (e.Column is GridGroupSplitterColumn)

{

un = e.Column.UniqueName;

}

}

And used the same UniqueName to access the GridGroupSplitterColumn in ItemDataBound event.

C#:

    protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if (e.Item is GridDataItem)
        {
            GridDataItem item = (GridDataItem)e.Item;
            if (RadGrid1.MasterTableView.GroupByExpressions.Count > 0) // If grouping is enabled
            {
                TableCell cell = (TableCell)item[un];
                // Add custom controls here
            }
        }
    }

 Feel free to share the comments, :)

Hi Shinu,
thx again for your reply. Unfortunately, the controls are not added when I try your code.
I set a couple of breakpoints, and the UniqueName returned is "column", just as you had in your code. I also set a breakpoint in the ItemDatabound handler - it gets executed, but the controls are not inserted.
My guess is (and I'm just guessing - new to the radcontrols) this is because I have the initial render of the control set to collapse all groups (meaning the cell isn't there). It seems there is a postback when the group is expanded and the itemdatabound event doesn't fire then (??).

Thx again!
