Get item template control from column

[Aaron Ellery]

Hi,

I am using the grid to view a table with multiple foreign keys. Not using a view, so I want to use a bunch of lookup combos to display the human readable descriptions for each foriegn key. To do this im using a rad combo as a template item for the databound cell. My issue is that I can't seem to find how to get an instance of this control in the codebehind so I can populate the list of values for the foreign key. Any ideas on how this could be done or suggestions of how to accomplish this without using a view? Currently I am binding the data via a datatable in the NeedsDatasource event.

aspx im using to declare the combo template is below.

Thanks.

Columns>

<telerik:GridBoundColumn DataField="DEPARTMENT_CODE_ID" HeaderText="Department" UniqueName="column1">

</telerik:GridBoundColumn>

<telerik:GridTemplateColumn DataField="MODULE_ID" HeaderText="Module" UniqueName="column3">

<EditItemTemplate>

<asp:TextBox ID="MODULE_IDTextBox" runat="server" Text='<%# Bind("MODULE_ID") %>'></asp:TextBox>

</EditItemTemplate>

<ItemTemplate>

<telerik:RadComboBox ID="RadComboBox1" runat="server" Enabled="False" SelectedValue='<%# Eval("MODULE_ID") %>'>

<Items>

Hi Aaron Ellery,

Thank you for contacting us.

You can get an instance of that combobox in ItemCreated:

protected void RadGrid1_ItemCreated(object sender, Telerik.Web.UI.GridItemEventArgs e)
        {
            if (e.Item is GridDataItem)
            {
                RadComboBox comboBox = e.Item.FindControl("RadComboBox1") as RadComboBox;
            }
        }

I hope that's helpful.

Hi Aaron,

You can also use the UniqueName property to access the Controls inside GridTemplateColumn.

CS:

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
    {
        if (e.Item is GridDataItem)
        {
            GridDataItem item = (GridDataItem)e.Item;
            RadComboBox comboBox = item["column3"].FindControl("RadComboBox1") as RadComboBox ;
        }
    }

Thanks
Princy.
