NestedViewTemplate parent item value

[Rayne]

I have a grid with a nested view template. Inside the nested view I have a checkbox. When the value changes, I need to check a value in the parent item's data. How do I get this value?

Using the code below I can get the parent Item, but its DataItem is null.

GridNestedViewItem nesteditem = (GridNestedViewItem)button.NamingContainer;
GridDataItem item = nesteditem.ParentItem;

What am I missing?

Hi Rayne,

I guess you want to change some value of the parent item when a control of checkbox is checked inside the NestedViewTemplate.Please try the below code snippet.

ASPX:

<telerik:RadGrid ID="RadGrid1" runat="server" OnItemCreated="RadGrid1_ItemCreated">
    <MasterTableView DataKeyNames="CustomerID">
        <Columns>
            <telerik:GridBoundColumn DataField="ContactTitle" HeaderText="Contact title"  UniqueName="ContactTitle">
            </telerik:GridBoundColumn>
        </Columns>
        <NestedViewSettings >
            <ParentTableRelation>
                <telerik:GridRelationFields DetailKeyField="CustomerID" MasterKeyField="CustomerID" />
            </ParentTableRelation>
        </NestedViewSettings>
        <NestedViewTemplate>
            <asp:Panel ID="Panel1" runat="server">
                <table>
                    <tr>
                        <td>
                            <asp:CheckBox ID="CheckBox1" runat="server" />
                        </td>
                    </tr>
                </table>
            </asp:Panel>
        </NestedViewTemplate>
    </MasterTableView>
</telerik:RadGrid>

C#:

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
   {
       if (e.Item is GridNestedViewItem)
       {
           CheckBox check = e.Item.FindControl("CheckBox1") as CheckBox;
           check.AutoPostBack = true;
           check.CheckedChanged += new System.EventHandler(check_CheckedChanged);
       }
   }

void check_CheckedChanged(object sender, System.EventArgs e)
   {
       CheckBox checkinner = (CheckBox)sender;
       GridNestedViewItem item = (GridNestedViewItem)checkinner.NamingContainer;
       if (checkinner.Checked)
       {
              string val = item.ParentItem.GetDataKeyValue("CustomerID").ToString(); //Access the DataKeyValue
              item.ParentItem["ContactTitle"].Text="Some Text";   //Access a bound column
       }
   }

Thanks,

Thanks. this bit of code is what I needed:

item.ParentItem["ContactTitle"].Text="Some Text"; //Access a bound column
