[Solved] NestedViewTemplate parent

[Jeroen Eikmans]

Hi,

I have a RadGrid with a NestedViewTemplate in a DetailTable in a DetailTable.
So the grid (without columns etc) looks like this :

<telerik:RadGrid ID="customerRadGrid">
    <MasterTableView DataKeyNames="CustomerID">
      <DetailTables>
         <telerik:GridTableView DataKeyNames="ProductID">
            <ParentTableRelation>
              <telerik:GridRelationFields DetailKeyField="CustomerID" MasterKeyField="CustomerID" />
            </ParentTableRelation>
            <DetailTables>
              <telerik:GridTableView DataKeyNames="SupplierID">
                <ParentTableRelation>
                  <telerik:GridRelationFields DetailKeyField="ProductID" MasterKeyField="ProductID" />
                </ParentTableRelation>
                <NestedViewTemplate>
                      <asp:Button ID="startButton" runat="server" Text="Start"
                        onclick="startButton_Click" />
                </NestedViewTemplate>
              </telerik:GridTableView>
            </DetailTables>
         </telerik:GridTableView>
      </DetailTables>
    </MasterTableView>
  </telerik:RadGrid>

In the template there is a button for the user to click.
When the user clicks the button i need to know what the parent row is, so i can get the datakeyvalue of that row.

I tried this by setting the row to selected as soon as the user expands it but since there can be multiple rows expanded this isn't working.

Anybody any ideas?

Hello Roel,

You can try out the following code to achieve the required scenario:
c#:

protected void startButton_Click(object sender, EventArgs e)
    {
        Button btn = (Button)sender;
        GridNestedViewItem nestedviewItem = (GridNestedViewItem)btn.NamingContainer;
        GridDataItem dataItem = (GridDataItem)nestedviewItem.ParentItem; //to access the parent row
        string strtxt = dataItem.GetDataKeyValue("SupplierID").ToString(); // to get the datakeyvalue
    }

Thanks
Princy.
