c# - Change cell color on different values - Gridview

Question

I need to distinguish two consecutive cells.

Each one in a row, if they have different values, when databindind the values to a gridview.

So, if in the row 1 I have the cell "ABC" and in the row 2 I have the cell "CBA".

I need to color each cell with a different color.

What is the best way to do it?

Answer 1

This is called Conditional Formatting

You can enable the RowDataBound Event in the markup

<asp:GridView ID="gridview1" runat="server" OnRowDataBound="RowDataBound">

</asp:GridView>

And put this in your Code-Behind file.

protected void RowDataBound(Object sender, GridViewRowEventArgs e)
{
    if(e.Row.RowType == DataControlRowType.DataRow)
    {
        if(e.Row.RowIndex == 0)     // This is row no.1
            if(e.Row.Cells[0].Text == "ABC")
                e.Row.Cells[0].BackColor = Color.Red;

        if(e.Row.RowIndex == 1)     // This is row no.2
            if(e.Row.Cells[0].Text == "CBA")
                e.Row.Cells[0].BackColor = Color.Green;
    }
}
