How to apply CSS to a GridView Row based on a condition

Assuming you have a GridView with a 'Discontinued' column. You now want to apply a different css class for all the rows that are Discontinued, then here's how to do so.

C#

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)

{

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

    {

        DataRowView drv = e.Row.DataItem as DataRowView;

        if (drv["Discontinued"].ToString() == "true")

            e.Row.CssClass = "selected";

    }

}

VB.NET

    Protected Sub GridView1_RowDataBound(ByVal sender As Object, _

                                         ByVal e As GridViewRowEventArgs)

        If e.Row.RowType = DataControlRowType.DataRow Then

            Dim drv As DataRowView = TryCast(e.Row.DataItem, DataRowView)

            If drv("Discontinued").ToString() = "true" Then

                e.Row.CssClass = "selected"

            End If

        End If

    End Sub
