It's allright the way you're using to find control from cell.

There may the chance of dropdown absense over there or the name you have written may be slightly different then the actual control name.

You could always move on by checking if the cell has control by following way.

C#

if (grd.Rows[0].Cells[0].HasControls())
        {
        }

Solution 2

The rows and cells in the grid view control are indexed as zero based. If the item code is in the first column, you need to access it at .Cells[0], not .Cells[1]. If you are getting null for the values that is the first thing I would validate.

he's getting the right value for val2. And since he's specifying the specific name, then one could assume that he's using the right indices...but you know what they say about assuming!

Solution 3

I wouldn't go that deep into the row, try removing the Cell property.

DropDownList val1 = (DropDownList)Gridview1.Rows[intRow - 1].FindControl("txtItemCode");
TextBox val2 = (TextBox)Gridview1.Rows[intRow - 1].FindControl("txtDescription");

Solution 4

My first guess would be based on the name you gave...txtItemCode implies a textbox, not a dropdownlist.

Even if that's true, step through your code. Put a breakpoint at the line that you set val1.

Then, add a watch for Gridview1.Rows[intRow - 1].Cells[1].FindControl("txtItemCode") and see what it returns. Does it return anything? If so, is it a dropdownlist?
