Hi All, We have A requirement Where we have disable controls inside a grid.These controls can be textbox, DropDownlist (in TemplateField), ComandField present inside the grid.We have to call a generic method for doing the same .(since it can be done for multiple grid.) PFB the code snippet we use. 
Which disables all the controls inside the page.
The bolded part of the code is used to loop inside a grid view.(Not Working.)Is this ideal way to deal with the requirement.Or can someone suggest be a better way.        
public void DisableMe(Page p1, string strStatus)
        {
            if (strStatus != null)
            {
                if (strStatus.ToUpper() == "TRUE")
                {
                    foreach (Control page in p1.Controls)
                    {
                        foreach (Control page1 in page.Controls)
                        {
                            foreach (Control page2 in page1.Controls)
                            {

            }
        }
 

U can use Foreach control c in GridViewRow R1  Enable/Disable
Do it for each row of DataGrid/Gridview
 
Please Mark as Answer if it solved ur problem.
