Grid Hierarchy ?

[Jason Bourdette]

I have a grid and I have added a Hierarchy which is working good but I was wondering if there is a way to selectively show the expand grid button based on content in a column.

For example if my first column is an order number and I want to have a nested Hierarchy but only for order numbers in the column that begin with a certain text string.

thx

Hello Jason,

Try the following code snippet to show/hide expand grid button based on the content in a column.

C#:

 protected void RadGrid1_PreRender(object sender, EventArgs e)
    {
        foreach (GridDataItem item in RadGrid1.MasterTableView.Items)
        {
            if (item["OrderID"].Text == "10249")//your condition
            {
                TableCell cell = item["ExpandColumn"];
                cell.Controls.Clear();
            }
        }
    }

Regards,
Shinu.

Just getting back around to looking at this code, and I see what it is doing but this is not exactly what i had in mind. I want to effect a nested grid not the top level grid.

is there something like RadGrid1.DetailsTableView.Items  (this didnt work but is there something like it?)

thanks

Hello Jason,

Please check out the following online documentation article which explains how to hide expand/collapse images when no records:
http://www.telerik.com/help/aspnet-ajax/grdhideexpandcollapseimageswhennorecords.html

You could modify the code snippets and hide expand/collapse buttons based on content in a column:

I hope this helps.
