Trying to make a DataGridView field a color if a condition is met.

[Norris Chappell]

Duh! Thanks.

[Norris Chappell]

Still getting the same error. :(

[Mathi Mani]

Can you post what value is coming in

e.Row.Cells[5].Text

It will give a better idea on what we are dealing with.

[Norris Chappell]

the count is 9.

[Norris Chappell]

sorry I meant 0.9500

[Mathi Mani]

decimal ActualFTE=Convert.ToDecimal(e.Row.Cells[5].Text);
if (ActualFTE > 1.25)

In the above code check whether e.Row.Cells[5].Text returns data that can be converted to decimal. Or add ToString() at the end and see if it helps.

decimal ActualFTE=Convert.ToDecimal(e.Row.Cells[5].Text.ToString());

[Norris Chappell]

Same error: Input string was not in a correct format.

[Mathi Mani]

Just to make sure everything is fine, try hardcoding the value and see if you still get the error.

decimal ActualFTE=Convert.ToDecimal("0.9500");

If this works without exception, then you can be sure, the problem is with the expression e.Row.Cells[5].Text. This expression you use should return some string (like your value 0.9500) that can be converted to decimal for the conversion to work without exception.

[Norris Chappell]

okay it didn't error this time but nothing changed.

[Mathi Mani]

May be the value ActualFTE is not greater than 1.25, as per your condition.

   if (ActualFTE > 1.25)
   {
      e.Row.BackColor = Color.Red;
    }

So the color will not be changed.

[Norris Chappell]

That is true for most of the 251 rows. I only see a couple that are over 1.25. So I should take out that code?

[Norris Chappell]

Do you think I should post all of my code to see if I have something missing?

[Mathi Mani]

When you want the row to be colored? Change the if condition based on that. It should work.

[Norris Chappell]

Not the whole row only that field. ActualFTE.

Refere this question for changing the color of a grid row based on some condition. The code is in Vb.Net but you can get the idea. How Can I Change A Rows Backcolour Based On The Value In The First Cell Of The Same Row[^]

[Norris Chappell]

Mathi, I was able to get it to work. Thank you for your help and patience. You and others have help me to complete this project.

protected void gvCATW_RowDataBound(object sender, GridViewRowEventArgs e)

{
if (e.Row.RowType == DataControlRowType.DataRow)
{

// To check condition on integer value
if (Convert.ToDecimal(DataBinder.Eval(e.Row.DataItem, "ActualFTE")) > 1.25M)
{
  e.Row.BackColor = System.Drawing.Color.Red;
}

}
