get itemdata on dropdownlist event of gridtemplatecolumn

[Jota]

Hello! I'm working with a RadGrid with HierarchyLoadMode="Client", in the second level of detailTables  I have a GridTemplateColumn with a dropdownlist like this:

<telerik:GridTemplateColumn HeaderText="Alta Petició" HeaderStyle-HorizontalAlign="Center" UniqueName="UNDDLAltaTop" ItemStyle-HorizontalAlign="left">
<ItemTemplate>
          <asp:DropDownList ID="DDLTP" runat="server" OnSelectedIndexChanged="DDLTP_SelectedIndexChanged" />
</ItemTemplate>
</telerik:GridTemplateColumn>

 I'm set datasource of DDLTP in itemDataBound event:

 

if (e.Item.OwnerTableView.Name == "Son")
{
    if (e.Item is GridDataItem)
    {
        GridDataItem item = (GridDataItem)e.Item;
        DropDownList ddl = (DropDownList)item["UNDDLAltaTop"].FindControl("DDLTP");
        setDatasource(ref ddl, "ID_TP");
    }
}

This works perfect!

 

Now I need to access to itemdata like (ItemCommand Event) to get the value of another column of the row

protected void DDLTP_SelectedIndexChanged(object sender, EventArgs e)
{

}

 

If I use an imagebutton to make the postback i can access itemData with ItemCommand Event but I don't like this solution:

<telerik:GridTemplateColumn HeaderText="Alta Petició" HeaderStyle-HorizontalAlign="Center" UniqueName="UNDDLAltaTop" ItemStyle-HorizontalAlign="left">
<ItemTemplate>
          <asp:DropDownList ID="DDLTP" runat="server"/>
          <asp:ImageButton  ID="BAltaPeticio" runat="server" CommandName="Altapeticio"           ImageUrl="../../Imatges/b_Add.gif" ToolTip="Alta Petició" />
</ItemTemplate>
</telerik:GridTemplateColumn>

Can you help me??

 

thanks

Hello Jota,

You can access the container grid item using the following approach:

protected void DDLTP_SelectedIndexChanged(object sender, EventArgs e)
{
    DropDownList list = (DropDownList)sender;
    GridDataItem item = (GridDataItem)list.NamingContainer;
}

Once you have a reference to the item, you can extract the desired values:

Hope this helps.
