[Solved] Find number of items in RadGrid DetailTables

[Dave Hollen]

Hello,

I have a RadGrid that contains a DetailTable.  In the DetailTable, I wish to add ImageButtons that can change the order of the items in the DetailTable.

What I need to be able to determine is, how many records will be in the detail table.  I need to know this so that for Rows 2 through n-1 (where n is the number of items), I can show both the "Up" and "Down" buttons, and for row n, I can just display the "Up" button. 

How can I determine the number of records that will be in the detail table?  I have tried on DetailTableDataBind, ItemDataBound, etc. and so far nothing has worked.  Any suggestions?  Perhaps I need to use DetailTableDataBind or something I have already tried, but with different code?

Thanks!

Hello Dave,

You can find the number of items in the child table in the PreRender event of the grid as shown below:
c#:

protected void RadGrid1_PreRender(object sender, EventArgs e)
    {
        int count = RadGrid1.MasterTableView.Items.Count;
        foreach (GridDataItem dataItem in RadGrid1.MasterTableView.Items)
        {
            if(dataItem.Expanded) // to avoid this condition check you can set MasterTableView>HierarchyLoadMode to Client
            {
                int count1 = dataItem.ChildItem.NestedTableViews[0].Items.Count;
            }

        }
    }

Thanks
Princy.
