Refresh RadGrid after change on another RadGrid

[Chris]

Hi,

I want to implement an interface with 2 RadGrid's with a plitter between them to give an 'Explorer' like view.  When the user clicks on a row in the left hand grid it identifies the item being clicked and will re-display the right hand grid to show details of the item selected.  I would have thought that this would be trivial but I can't seem to get it to work.

I have captured the SelectedIndexChanged event for the LH grid but when I look at the gridParts.SelectedItems[0].DataItem value it is always NULL which I am not sure why.

Any-one got an example of using 2 grids in this way?

Hello Chris,

you can use DataItem only in itemDataBound Event in other event it is always null.

please You can achieve your requirement by using DataKeyNames.

<MasterTableView DataKeyNames="ID">

if (RadGrid1.SelectedItems != null && RadGrid1.SelectedItems.Count > 0)
        {
            string strId = (RadGrid1.SelectedItems[0] as GridDataItem).GetDataKeyValue("ID").ToString();
        }

Let me know if you have concern.


Thanks,

Hello Chris,

Try the following code snippet to access the DataKeyValue from SelectedIndexChanged event.
C#:

protected void RadGrid1_SelectedIndexChanged(object sender, System.EventArgs e)
{

 ID=  RadGrid1.SelectedItems[0].OwnerTableView.DataKeyValues[RadGrid1.SelectedItems[0].ItemIndex]["CustomerID"] ;
}

Thanks,
Princy.

Thanks - works great - however does this mean that I cannot access a specific column value directly uunless the column is also set within the DataKeyNames?

Hello Chris,

protected void RadGrid1_SelectedIndexChanged(object sender, EventArgs e)
    {
        GridDataItem item = RadGrid1.SelectedItems[0] as GridDataItem;
        string strId = item["ID"].Text;//ColumnUniqueName
    }

<telerik:GridBoundColumn DataField="ID" UniqueName="ID" HeaderText="ID">
                      </telerik:GridBoundColumn>
