Yes, I want to expose a event that I can hook too.
So, I can tell it to fire in the local control... but pretty much do nothing locally... but then hook it to a page event that will do the heavy lifting.

Have you added an AsyncPostBackTrigger[^] for the control?

ASP.NET

<asp:UpdatePanel runat="server" UpdateMode="Conditional">
  <ContentTemplate>
     <uc:CusParamTextBox ID="CusParamTextBox1" runat="server" OnExposedUpdate="Update" />
  </ContentTemplate>
  <Triggers>
    <asp:AsyncPostBackTrigger ControlID="CusParamTextBox1" EventName="ExposedUpdate" />
  </Triggers>
</asp:UpdatePanel>

I did try something like that, but a little different because I am adding the controls dynamically to a existing update panel.

I did try but with no luck..

SQL

CusParamTextBox tmpctrlx = new CusParamTextBox();
tmpctrlx.ExposedUpdate += new EventHandler(UpdateText);
ScriptManager1.RegisterAsyncPostBackControl(tmpctrlx);
CusParamControls.Controls.Add(tmpctrlx);

and on the page that contains the dyn control

<asp:UpdatePanel runat="server" ID="upMain" Visible="true" ChildrenAsTriggers="true" UpdateMode="Conditional">
    <ContentTemplate>
        <asp:Panel runat="server" ID="CusParamControls"></asp:Panel>
    </ContentTemplate>
</asp:UpdatePanel>

Sorry, I'm not overly familiar with the UpdatePanel. You might be better off posting this new issue in its own thread.

NB: It would be better to post the question in the ASP.NET forum[^].

Hi Rich,

Its ok, I manged to figure it out..
I wanted to add the solution to the post too so other may do the same.

Right after your add your control, and then your event via the init...
If you want to put your control inside a update panel and stop a full page post back then you must register your control with the parent page and do it inside the actually control code itself... outside dont seem to work via the main page containing the control.

protected override void OnInit(EventArgs e)
{
base.OnInit(e);

ScriptManager script = ScriptManager.GetCurrent(Page);
TxtParamValue = new TextBox();
TxtParamValue.TextChanged += new EventHandler(TxtParamValue_TextChanged);
if (script != null) { script.RegisterAsyncPostBackControl(TxtParamValue);}
base.Controls.Add(TxtParamValue);
}

Thanks, and enjoy all!

Hi All,

First time posting here, long time programmer..

So, I have a need for custom controls that I am using to dynamically render a list with call backs..

So, far I had no problem doing simple inherited based controls and hooking their callbacks...
IE CusControl : TextBox...
Then its fairly easy to hook the TextChanged event and add the controls a dynamic list and catch the post backs.

Now, the hard part is

Hi,

I have created a project with a third party control which has a distributable license.When I create a set up to this project and when I implement in other place it works fine.

At the same time when I add the dll files to another existing project and try to integrate both the project I get license issue. The message I receive is control expired error.

Though the license file is embedded with the dll.

Regards,
N.ShanthaKumar.

I have no idea what type of mail server you are using, but looking into the log files and mail storage you should be able to work out where from the email was sent.

It's possible to sign a PDF using a certificate, and yes, that can be built with C#. What USB-token? If that's what contains the certificate, then you'd be writing some additional code to read from it.
