I have a hierarch grid with more than 3 levels, i would like to select multi rows using code below. But my problem is whenever i have 3 or more levels the item.selected part doesnt seem to work anymore. Its just working for the first 2 levels.
protected void btnOk_Click(object sender, EventArgs e)
{

Cursor.Current = Cursors.WaitCursor;
/foreach (GridDataItem item in rdgLocation.MasterTableView.ItemsHierarchy){
if (item.Selected)
{

//do something;
}
}
i have tried replacing rdgLocation.MasterTableView.ItemsHierarchy by rdgLocation.MasterTableView and by rdgLocation.Items but it still doesnt work.
Does anyone know what im doing wrong.

Hi,

The RadGrid.Items collection contains all items from all tables in the hierarchical structure of Telerik RadGrid. By simply looping through the collection and based on the Name property that you set for each hierarchy you can access all data-bound items, their controls and so on:

CS:
foreach (GridDataItem item in RadGrid1.Items) 
   if (item.OwnerTableView.Name== "MyTableName") 
   { 
       // if you need you may also check the parent item keys here 
        if ((item.OwnerTableView.ParentItem as GridDataItem).GetDataKeyValue("MyKeyFieldName").ToString() == "some key value") 
        { 
           // operate with the controls in a custom manner 
        } 
   } 
}   


Thanks,
Princy

Hi Princy
Thank you very much,

On hovering over the rdgLocationItems in debug mode i have realised that the count for the rdgLocation.Items is 96, insteady of 125, the only records counted are those that are at levl 1 and level 2, the rest are not.
same with the count for rdgLocation.MasterTableView.ItemsHierarchy its 96.
Please note that the selected item on the first and secend level are working fine. Could it be that only the first 2 levels are picked by this method.
My code is like this:
foreach (GridDataItem item in rdgLocation.Items)
{
if (item.Selected)
{
try{
if (strCondition == "Locations")
{Session[
"LocationID"] = Session["LocationID"] + item["LocationID"].Text.ToString() + "-" + item["Location"].Text.ToString() + "-" + item["ParentLocationID"].Text.ToString() + ";";
}
else
{
Session[
"LocID"] = item["LocationID"].Text.ToString();
Session[
"LocName"] = item["Location"].Text.ToString();
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}

}

}

Hie Princy
Look at the information on my debug immediate window

?rdgLocation.Items[2]["location"].Text

"Nedbank"

?rdgLocation.Items[2].Selected

false

but Nedbank is a selected row on my grid. this is only happening on rows at the third level and there after.

item.OwnerTableView.Name is returning a space,"", but i can use the one above because im sellection from only one table so im not keen on this.

I think there is a problem with the control. i Have tried solving this problem many times without success, I hope the Telerik Support will have a serious look at it.
