Hello Ron,

You can access the RadComboBox, inside ItemTemplate of RadGrid, in the SelectedIndexChanged Event by using the Sender property. Here is a sample code.

aspx:

<telerik:GridTemplateColumn DataField="CategoryID" HeaderText="Site" SortExpression="SC"

UniqueName="SC">

<ItemTemplate>

<telerik:RadComboBox ID="RadCombo1" DBSelectedValue='<%# Eval("CategoryID") %>' runat="server"

AutoPostBack="true" OnSelectedIndexChanged="RadCombo1_SelectedIndexChanged">

<Items>

<telerik:RadComboBoxItem Text="Item1" Value="1" />

<telerik:RadComboBoxItem Text="Item2" Value="2" />

<telerik:RadComboBoxItem Text="Item3" Value="3" />

<telerik:RadComboBoxItem Text="Item4" Value="4" />

<telerik:RadComboBoxItem Text="Item5" Value="5" />

<telerik:RadComboBoxItem Text="Item6" Value="6" />

<telerik:RadComboBoxItem Text="Item7" Value="7" />

<telerik:RadComboBoxItem Text="Item8" Value="8" />

</Items>

</telerik:RadComboBox>

</ItemTemplate>

</telerik:GridTemplateColumn>

. . . . . . . . . . . . . . .

<asp:Label ID="lbl1" runat="server">

</asp:Label>

C#:

protected void RadCombo1_SelectedIndexChanged(object sender, RadComboBoxSelectedIndexChangedEventArgs e)

{

lbl1.Text = (sender as RadComboBox).SelectedValue;

}

Thanks,
Shinu.

Thanks for taking the time Shinu,

I'm not necessararily looking to set the label control to the selected value of the combo box, I'm just trying to set the value of the label when combo box selectedindexchanged and for some strange reason neither of the textbox or label controls outside the grid would work. I did try to implement your solution just to see if it would work and unfurtunately it didnt. Here's my code; The last line of the code block you can see lblSubtotal is set after a foreach loop, but it never happens on the page.

protected void RadComboBox1_OnSelectedIndexChanged(object sender, RadComboBoxSelectedIndexChangedEventArgs e)

{

RadComboBox cmboBx = (sender as RadComboBox);

GridDataItem dataItem = cmboBx.Parent.Parent as GridDataItem;

string item = (dataItem["Items"].FindControl("ddlItems") as RadComboBox).Text;

(dataItem["Description"].FindControl("txtDescription") as RadTextBox).Text = InvoiceItems.GetItemDetails(item, 3).Description;

string price = (dataItem["Price"].FindControl("txtPrice") as RadNumericTextBox).Text = InvoiceItems.GetItemDetails(item, 3).Rate.ToString();

string qty = (dataItem["Qty"].FindControl("txtQty") as RadNumericTextBox).Text = "1";

string discount = (dataItem["Discount"].FindControl("txtDiscount") as RadNumericTextBox).Text = "5";

double total = 0;

total = (double.Parse(price) * Int32.Parse(qty)) - double.Parse(discount);

(dataItem["Amount"].FindControl("lblAmount") as

Label).Text = total.ToString();

double subTotal = 0;

foreach (GridDataItem gridItem in grdInvoiceItems.Items)

{

double lineTotal = double.Parse((gridItem["Amount"].FindControl("lblAmount") as Label).Text);

subTotal += lineTotal;

}

lblSubtotal.Text = subTotal.ToString();

}
