RadNumericTextBox OnValueChanged to pass CommandArgument to back-end

[Aron]

Hello,

I would like to use the RadNumericTextBox as a way to change the quantity of items in a cart.

How can pass the OrderItemId to the back-end C# for logic to happen?

 

<telerik:RadNumericTextBox OnTextChanged="QuantityChanged"  runat="server" Width="30" MinValue="1"
                                 Visible='<%# AllowEditQuantity(Eval("Item.ProdType"), Eval("Show.EventType")) %>'
                                 Value='<%# decimal.Parse(Eval("Item.Quantity").ToString())%>'
                                 CommandArgument='<%#Eval("Item.OrderItemId") %>'>
                                 <ClientEvents OnValueChanged="squareValue"/>
                                <NumberFormat DecimalDigits="0" />
                             </telerik:RadNumericTextBox>

Hi Aron,

To update the value in the data source you would need to access the value that is entered in the numeric input control. Please examine the following article that describes how you can access controls that are placed inside grid cells.

• http://docs.telerik.com/devtools/aspnet-ajax/controls/grid/rows/accessing-cells-and-rows#accessing-controls-in-template-column

Also check out the article below that illustrates how you can update the data for RadGrid manually.
