Hi,

Does anyone know how to add columns dynamically to a DataGrid.

i populate the grid using the .ItemDataBound

the current structure of my grids are as below....

<asp:templatecolumn>
<headertemplate>
<asp:label id="lblDisp" runat="server" text="" tooltip="" />
</headertemplate>
<itemtemplate>
<asp:label id="lblSales" runat="server" cssclass="GridTDText"></asp:label>
 
<asp:label id="lblProfit" runat="server"
cssclass="GridTDText"></asp:label>
 
<asp:label id="lblMargin" runat="server"
cssclass="GridTDText"></asp:label>
</itemtemplate>
<edititemtemplate>
<asp:textbox id="txtSales" runat="server" cssclass="GridTextBox Small"

></asp:textbox>

<asp:textbox id="txtProfit" runat="server" cssclass="GridTextBox
Small"></asp:textbox>
 
<asp:textbox id="txtMargin" runat="server" cssclass="GridTextBox
Small"></asp:textbox>
</edititemtemplate>
</asp:templatecolumn>

One approach is to simply add an extra column to your dataset and then bind
the dataset to the datagrid. The extra column would then show up
automatically.
