hi
C#
gridview formatting dynamically change gridview cell color based on cell value in AspNet 


my code:
C#
protected void Page_Load(object sender, EventArgs e)
   {
       if (!this.IsPostBack)
       {
           this.BindGrid();
       }
   }
   private void BindGrid()
   {
       using (DataSet ds = new DataSet())
       {
           //ds.ReadXml(Server.MapPath("~/Customers.xml"));
           int i;
           for (i = 0; i < 20; i++)
           {

               if (System.IO.File.Exists(Server.MapPath("~/Files/SiteInfo" + i + ".xml")))
               {
                   ds.ReadXml(Server.MapPath("~/Files/SiteInfo" + i + ".xml"));
               }
           }
           GridView1.DataSource = ds;
           GridView1.DataBind();
       }
   }

   protected void OnPageIndexChanging(object sender, GridViewPageEventArgs e)
   {
       GridView1.PageIndex = e.NewPageIndex;
       this.BindGrid();
   }


What I have tried:

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
int Temperature = int.Parse(e.Row.Cells[4].Text);

if (Temperature <= 50)
e.Row.Cells[4].BackColor = System.Drawing.Color.Red;
else if (Temperature <= 30)
e.Row.Cells[4].BackColor = System.Drawing.Color.Yellow;
else
e.Row.Cells[4].BackColor = System.Drawing.Color.Green;
}

}

i tried this code but not working..

It should work as the code looks fine.
Make sure
1. You have no hidden columns in which case your Temperature column index may b different than what you see.
2. Debug and check if the control hits the break point.

I believe that is the correct event to do it in so put a breakpoint there and see what happens.

Is the event handler wired up? Your screen-shot shows that the values in cell 4 are not integers, so I would expect the int.Parse line to throw an exception.
