Few months ago I wrote a sample demo on how to Add Dynamic Rows in GridView with TextBoxes and how to Add Dynamic Rows in GridView with DropDownLists. I have had a few comments and emails asking how to do the same with a combination of TextBox and DropDownList. In this post, I'm going to show you the way on how to this. Here are the code blocks below: ASPX: <asp:gridview ID="Gridview1" runat="server" ShowFooter="true" AutoGenerateColumns="false"... <Columns> <asp:BoundField DataField="RowNumber"...
