Need to find RadNumericTextBox in Edit FormTemplate

[Steve Y]

I have a Grid with an Edit FormTemplate which has six controls of Type RadNumericTextBox all sitting inside a table.

The grid goes into edit mode and, as each textbox has data entered into it, I need to be able to find the other five, get their values and keep a running total which I'll be displaying elsewhere on the page. I have the grid ajaxified and each control has autopostback="true". I have the onTextChanged event for each textbox wired and I'm seeing each control fire in code behind.

So far so good. However, I cannot find the other five textboxes. So far in the research I've done, I see many examples of using grid events such as editing and inserting etc which gives an easy path to find the controls using:

GridEditFormItem item = e.Item as GridEditFormItem;

However, all I have is either the sender as my RadNumericTextBox or RadGrid1 as a starting point for any contained controls.

Can anyone help point me in the right direction.

Thanks, Steve

Hi Steven,

You can use OnTextChanged server-side event where you can cast sender argument to RadNumericTextBox and find the grid item using NamingContainer property:

GridItem item = (GridItem)((RadNumericTextBox)sender).NamingContainer;

Now you can use FindControl() for GridItem to find desired control by ID.
