I want to change the forecolor of the row which row contains a specific word "MG". I used the below code but it is not working on the web application.

What I have tried:

C#

    protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
       if (e.Row.RowType == DataControlRowType.DataRow)
       {
           if (e.Row.Cells[0].Text.ToString().Contains("MG"))
           {
                   e.Row.ForeColor = System.Drawing.Color.Blue;
                   e.Row.Style["text-align"] = "Left";
           }
           else
           {
                   e.Row.ForeColor = System.Drawing.Color.Black;
                   e.Row.Style["text-align"] = "Left";
           }
      }
}

Debug it and see if it is even hitting your code the way you want to.

firstly I tried by using bound field then my code works well for color changing but my main work is with the Template field so when I check with breakpoints. it does not go to if condition and always go to else statement. what to do?. my code is working properly with the bound field but not with a template field.

It means that e.row.cells[0] is not what you think it is. So put a breakpoint there and then you can examine what it is and get it fixed.

What color is it? What happens when you change "black" to "not black"?

Check if you actually get the right HTLM code on the client side... (probably not)
I would also advise to use class names instead of inline style...

That's an expected behavior since e.Row.Cells[0] refers to BoundField columns. When using TemplateFields, you need to use FindControl [^] method. For example:

C#

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
       if (e.Row.RowType == DataControlRowType.DataRow)
       {
           //if you have a Label control within TemplateField Column
           string labelValue = ((Label)e.Row.FindControl("YourLabelControlID")).Text;
           if (labelValue.Contains("MG"))
           {
                   e.Row.ForeColor = System.Drawing.Color.Blue;
                   e.Row.Style["text-align"] = "Left";
           }
           else
           {
                   e.Row.ForeColor = System.Drawing.Color.Black;
                   e.Row.Style["text-align"] = "Left";
           }
      }
}
