View Full Version : [CLOSED] Loading usercontrol with only the path (usercontrol contains ext.window inside)

Feb 13, 2012, 6:30 PM

I´m creating a reusable GridPanel, where I set the SQL query and path to usercontrol for the maintenance of records (add and edit)...

What I need is load my usercontrol with just the path for this usercontrol.

My usercontrol has a ext.window inside with 'ok' and 'cancel' buttons. When the 'ok' button is clicked, I want update my GridPanel.

Thanks for any help!

Could you concretize the questions? How do you try? What problems are you facing?

As well, I'm not sure that I understand the following well:

What I need is load my usercontrol with just the path for this usercontrol.

Please clarify.

Hi Danill!

I created an example to demonstrate what I need.

I can load the UC1 and UC2 only with the path (The path to the UserControls is in combobox).

But the UC3 (which contains a ext.Window) I can not load using ext: UserControlLoader.

The only way that I'm able to load the UC3 is registering the usercontrol on page (see 'Load UC3' button) but this I do not want.

I want to load the UC3 with only the path, how I do with the UC1 and UC2. (but not inside the TabPanel).

I would also like to delegate a function to the UC3 to refresh the page that loaded the UC3.

uc3 code behind

Public Class uc3
Inherits System.Web.UI.UserControl

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

End Sub

Public Sub Start()
End Sub

End Class

This might look something like this.

Example C#

protected void LoadUC3(object sender, DirectEventArgs e)
UserControlLoader ucl = new UserControlLoader();
ucl.Path = "TestUC.ascx";
(ucl.UserControls[0] as TestUC).Start();

TestUC.ascx is the user control with Window. The "TestUC" is the class name of that user control.

Hi Daniil...

I made the changes you suggested ...
The ext.window opens... but it does not close when I click in close button of window (x).

My code looks like this:

Protected Sub LoadUserControl(sender As Object, e As DirectEventArgs)

Dim ucl As UserControlLoader = New UserControlLoader()

ucl.Path = cmbUC.SelectedItem.Text
ucl.UserControlID = "UC_" & CStr(Rnd() * 1000000000000000.0)
DirectCast(ucl.UserControls(0), SuperaWeb.uc3).Start()

End Sub

I guess it's closed on the first attempt, but not close on the second one or further, right?

I think it's an id conflict.

I've just tried your code and the following

ucl.UserControlID = "UC_" & CStr(Rnd() * 1000000000000000.0)
produced 2 same ids of 3 (!).

You should change this policy, I mean producing random ids.

Hi Daniil ...

you're right!

I use now System.Ramdom.Next to generate UserControlID. It´s working.

Thanks a lot...

Now, I need get a return of my usercontrol. this return 'say' if I need refresh my GridPanel.

It has an easy example of how I could do this?

I think it would be best to start a new forum thread since the initial question has been answered (in the thread's title).

Ok, no problem

Thanks a lot for answer this question!
