Hi,

I am struggling with getting a user control to work in the backend.

For testing purposes, I have created a very simple user control, that updates a label with current datetime when a button is clicked. But when I click the button, nothing happens. I have inserted my usercontrol below:

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="WebUserControl1.ascx.cs" Inherits="usercontrols.WebUserControl1" %>

<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>


<div>


<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
    <asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click"></asp:Button>

</div>

</ContentTemplate>
</asp:UpdatePanel>

In my codebehind I have:

        protected void Button1_Click(object sender, EventArgs e)
        {
            Label1.Text = DateTime.Now.ToString();
        }

In dashboard.config I have inserted

     <tab caption="MyTest">
              <control addPanel="true">/usercontrols/WebUserControl1.ascx</control>
      </tab>

Any help is appreciated.

Thanks

Thomas

Hi Thomas

Could you try to hardcode a text, which is displayed instead of a date maybe? Don't know if it could be something with the date formatting.

I'm thinking like setting Label1.Text ='test'; for instance.

Hi Jan

I tried to hardcode the text, but it did not make any difference.

Btw I am on Umbraco 4.6

Hi Thomas,

How is your development setup? Are you building your control in an external web-app project, or are you writing your code, and building directly in the Umbraco website.

Either way you need to make sure that the dll, that contains the compiled code for your user control is copied to the bin folder of the site at runtime.

Hi

The strange thing is that the exact same usercontrol works fine in the frontend-website. It is only in the backend, it does not work.

The usercontrol is developed in the umbraco website.

thanks

Thomas

Hi Thomas

Hmmm, maybe it's caching that is the problem then - what happens if you clear it?

Hi Jan

I tried both clearing the browsercache and I also tried republishing the site, but it didn't solve the problem. I tried adding OnClientClick to see if it is only serverside-events which are not fired or if it is also clientside-events. The clientside-events are working but not the serverside-events. Do I need to register the serverside-events somehow besides the normal "OnClick" flow? Are there any casing conventions or something else, that I should be aware of?
```
<asp:LinkButton ID="button1" runat="server" Text="Button" OnClick="button1_Click"
                OnClientClick="alert('test');"></asp:LinkButton>
```
Thanks

Thomas,

I've been trying to figure out this same issue as well, and finally figured out what the problem was. If you're using a default installation of 4.6.1, one of the dashboard tabs in the Content area is Change Password. The changepassword usercontrol is using field validators in order to confirm that a user enters values in the textboxes. On your simple control, when it attempts to do a postback the runtime is first processing the field validators on the Change Password tab, and preventing a postback from occuring as the textboxes are not populated.

If you comment out the Change Password tab in the dashboard.config your usercontrol will execute properly.

Hi Andy

thanks, it works. I don't think I would have figured it out myself :-)

best regards
