[Solved] Get Column value from e.Row.DataItem in RowDataBound event of ASP.Net GridView

This way

C#

protected void OnRowDataBound(object sender, GridViewRowEventArgs e)
{
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            DataRowView dr = (DataRowView)e.Row.DataItem;
            string field1 = dr[0].ToString();
            //OR
            field1 = dr["name of field1"].ToString();
        }
}

VB.Net

Protected Sub OnRowDataBound(ByVal sender As Object, ByVal e As GridViewRowEventArgs)
    If e.Row.RowType = DataControlRowType.DataRow Then
        Dim dr As DataRowView = CType(e.Row.DataItem, DataRowView)
        Dim field1 As String = dr(0).ToString()
        'OR
        field1 = dr("name of field1").ToString()
    End If
End Sub
