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.

There's quite some examples on digitally signing a PDF. I suggest you start there Smile | :)

Looping between different functions

spin_108513-Aug-13 13:00

spin_1085

13-Aug-13 13:00

Hello again Code Project!

Here is the deal, I have two separate functions called InputData and DisplayPlayerData. Each of these functions have loops inside of them. The loop in InputData is supposed to get player's name and player's score, breaking the loop with a sentinel and not to exceed 100 players. No problem.

The other function, DisplayPlayerData, has a loop to display the name and score of each player.

I am thinking that I could use a state controlled while loop. What I really need to know is how to bring the input data from the first function into the second function. Would this function look like public static void DisplayPlayerData(){} or do I need to declare a few variable in the ()?
