How to update

[Weilun]

I am new to telerik and i want to ask how to update in radgrid with EditMode="InPlace" and without user double-click on the row
i saw this demo (http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/editondblclick/defaultcs.aspx) which require user to double-click the row to edit
In my case i want to update the data in RadNumericTextBox without the user double-click on the row.

This is my RadNumericTextBox

<telerik:GridTemplateColumn DataField="quantity"
                FilterControlAltText="Filter TemplateColumn column" UniqueName="quantity"
                HeaderText="Quantity" SortExpression="quantity">
                <ItemTemplate>
                    <telerik:RadNumericTextBox ID="quantityTextBox" runat="server"
                        ShowSpinButtons="True" width="50px"
                        DbValue='<%# Convert.ToDouble(Eval("quantity")) %>'
                        DataType="System.Int32" Culture="en-SG" NumberFormat-DecimalDigits="0" MinValue="0" MaxValue="999" ClientEvents-OnValueChanging="editQuantity">
                </telerik:RadNumericTextBox>
                </ItemTemplate>
            </telerik:GridTemplateColumn>

The RadNumericTextBox ClientEvents-OnValueChanging="editQuantity" and i am stuck at the javascript.
I am not sure of how to update without getting the selected rows.

Sorry about my bad english and thank everyone for reading my problem or giving me advice/help.

Hello,

You can set AutoGenerateEditColumn as true in RadGrid. This will add a GridEditCommandColumn with  Edit command name to the Columns collection.

Thanks,

Thank Princy.
I know that by setting AutoGenerateEditColumn to true it will generate a edit colum.
Is there any other way for me trigger the update function by using the ClientEvents-OnValueChanging in my RadNumericTextBox.
Mean that if user change the value in the RadNumericTextBox it will auto update with the new value.

Thank for replying.
