What is Code behind? What do you mean by C#?

Make them disabled) Something like

C#

myTextBox.Enabled = false;

In this case user would not be able to change value in textbox.

Edit To validate numbers, you should write a method, that will occur when text in textbox is changed (take from events in textbox) and it should check, if there are only numbers or not.

You can use RegularExpressionValidator for that TextBox.

Refer - Re: How validate in Gridview textbox as numeric[^] for one Example.

Then you can go for Soultion 1 by Alexander Dymshyts.

But handling Validations at the client side is a good and better approach.

Solution 3

on click of the grid event write code to check for the text box editing. if both condistion satisfied than you can go for regular expression which allow user to enter only numeric [0-9] something kind of.

in this way you can achieve your desire functionality.
