Dynamically Adding Controls to User Control
Hi to all,
first, here is what I have on my .ascx code:
<asp:Label ID="lblCategory" runat="server" Text="Category" /> <asp:DropDownList ID="ddlCategory" runat="server"></asp:DropDownList>
<table>
<tr>
<td>
<asp:Label ID="lblItem" runat="server" Text="Item Question"/>
</td>
<td>
<asp:Label ID="lblType" runat="server" Text="Item/ Question Type" />
</td>
<td>
<asp:Label ID="lblChoices" runat="server" Text="Choices" />
</td>
</tr>
<tr>
<asp:PlaceHolder ID="phItemPlaceholder" runat="server"></asp:PlaceHolder>
</tr>
</table>
<asp:LinkButton ID="lbtnAdd" runat="server" Text="[Add More Item/Question]" />
What I would want to happen is that, when the user clicks on the lbtnAdd,
it will automatically add text boxes on the specified place holder (phItemPlaceHolder) with in the .ascx pageI already know how to programmatically add the user control on the, say for example default.aspx page.
My problem is how to add controls dynamically, say textboxes on the user control.
Please aide me with this.
thanks in advance
Moist
