What exactly do you mean be "gridview"? Full type name, please. When it comes to UI, you should always tag the UI library/framework or application type you are trying to use.

Solution 1

I assume this is ASP.NET. Try this:

C#

protected void Your_GridView_RowDataBound(object sender, GridViewRowEventArgs e)
{
   if (e.Row.RowType == DataControlRowType.DataRow)
   {
         for (int i = 0; i < e.Row.Cells.Count; i++)
         {
           if (e.Row.Cells[i].Text == "&nbsp;")
           {
                e.Row.Cells[i].Text = "not available";
           }
         }
   }
}

Sir, It's working for only textboxes inside gridview. But I am trying to check boundfield value.
when I am retrieving the value of the empty cell, it is showing only a space, but when I am checking the length of string of thet cell it's giving 6.

First of all,the code i provided doesn't point at any textbox or any control. Check the value that you are binding to that GridView. If its showing length of 6,it means that its not empty. You stated in your question that for null value its showing empty. In that case,above code works.

yes, in my database table the value is showing null. But when I am binding with gridview and checking null value for cell, i am not getting output.
In message alert box, the empty cell is showing blank, but when m getting the length it is showing 6.
