Every time I press the "Test" button, only one textbox is generated. If I click twice, I expect two textboxes to appear.
I attempted this solution, and it seems to work well except for one issue. The textbox is recreated each time so the user's input is lost...
Aspx:
<asp:UpdatePanel ID="upTest" runat="server">
<ContentTemplate>
<asp:Button ID="btnTest" runat="server" Text="Test" OnClick="btnTest_Click" />
<asp:Panel ID="pnTest" runat="server" />
</ContentTemplate>
</asp:UpdatePanel>
Code-behind
protected void btnTest_Click(object sender, EventArgs e)
{
pnTest.Controls.Add(new TextBox());
}
