asked on GridView Cell Color Red If Text Empty?
The following code changes the entire column to Red, however I would like to just change Only cells with empty text.
Q. How can I change Only certain Cells Red and not the entire column?
protected void gridView1_RowDataBound(obj
{
if (e.Row.RowType == DataControlRowType.DataRow
{
if(e.Row.Cells[7].Text.Con
e.Row.Cells[7].BackColor = System.Drawing.Color.Red;
}
}

maybe coz your that column would be empty that's why the condition is true to get the cell color Red

Okay, here's how it's done in RowDataBound (similar to MajorBigDeal).
I can now read text of both:
protected void gridView1_RowDataBound(obj
{
foreach (GridViewRow row in gridView1.Rows)
{
if(row.Cells[6].Text == "10")
row.Cells[6].BackColor = System.Drawing.Color.Red;
if(((Label)row.FindControl
((Label)row.FindControl("l
}
}
I can now read text of both:
asp:BoundField
asp:TemplateField (Text='<%# Bind("FirstName") %>'>).
asp:TemplateField (Text='<%# Bind("FirstName") %>'>).
protected void gridView1_RowDataBound(obj
{
foreach (GridViewRow row in gridView1.Rows)
{
if(row.Cells[6].Text == "10")
row.Cells[6].BackColor = System.Drawing.Color.Red;
if(((Label)row.FindControl
((Label)row.FindControl("l
}
}

New Problem:
1. asp:CommandField won't 'fire', throws error:
"Object reference not set to an instance of an object."
However, asp:ButtonField works fine.

Yes but it doesn't make sense to put that in row data bound because you are iterating the entire grid for every row. For example, if your grid has 100 rows , your loop will run 10000 times. I guess it doesn;t really matter but I think it would be better in the page load.

I'll give you points because your solution works, but not in RowDataBound.
