[Solved] Value of numeric textbox in Template column zoroed on sort

[idwaikat]

Hello all.

I have a template column inside a grid, this column contains numeric text box as follows:

	<telerik:GridTemplateColumn DataField="Cost" HeaderText="Cost" UniqueName="Cost">
	<ItemTemplate>
	<telerik:RadNumericTextBox runat="server" ID="numtxtCost" Width="80px"></telerik:RadNumericTextBox>
	</ItemTemplate>
	</telerik:GridTemplateColumn>

when trying to sort the grid (by clicking the header column of any other column) the entered (not saved yet) values of the template column vanish; the numeric textboxes re-initialized to zeros...


do you have any idea of how to fix it

Thanks

Hi,

The Numeric Textbox control text will not be persisted on postbacks, so you need to persist the text state on TextChanged event of the textbox. A similar scenario wherein the checked state of a checkbox placed inside a TemplateColumn, is persisted is illustrtated in the following help document. Probably this should help you get started:
Persisting CheckBox control state in GridTemplateColumn on rebind

Thanks
Princy.

Thanks Princy, but the link you provided gives me: The system cannot find the path specified.

I think this is the correct link .

It seems that the solution depends on manuall coding and using viewstate to store/read values for each control.

I'll try it.

Thank you.
