I want create a user control (Div) like panel to be used in all my web pages. For example, The UserControl can have two DIVs or TRs with a background design. If it's added to a Page, the UserControl has to allow controls to be added into it, i.e. Divs, Labels, and TextBoxes. The height of the div should be AUTO.

I'm trying to create a user control class that extends Panel. Essentially, what I want to do is to have a panel that fires off an event whenever it's clicked upon.
So, I create something like this:
[Code]....
And then, in the ClickPanel.ascx.cs file:
[Code]....
I'm not exactly sure whether this would work as I haven't had the opportunity to test it yet.
The problem is that I can't have a class inherit from Panel. Creating a user control class requires that my class extend User Control - at least that's what the error messages have been saying up until now. The problem is that if I do extend it from the base class of UserControl then I lose all the functionality of the Panel itself and the entire thing is rendered pointless.
I'm attempting to create a simple menu user control just as outlined here.
The attached code results in an "Object reference not set to an instance of an object" error, but I can't figure out why.

View 5 RepliesI am trying to create a web page, that use a user-control (the user control is win-form).I am getting the message : That assembly does not allow partially trusted callers.I put the dll on c:windowsassembly, but I don't know why I getting the above.Here is my code

i created a user control called userCon.asxc. may i know how do i do when i click on button1, then the userCon.asxc will load into panel1?
I checked on internet, but found only those loading the user control to page when execute. What i want is to load user control into panel1 when button1 is click. .
I have 2 user controls. The first user control generates custom paging and assigns the output as a string literal. The second user control is a simple repeater which uses values from the paging control via a query string to decide which relevant chunk of data to retrn.
The custom paging control is embeded in the custom reapeater control. In my my page, I simply call the customer erpeater control and everything works treat.I now want to add update panels to this but I can't think where to start.
The paging control looka like this.

I have a user control with a panel on it:
CustomControl.ascx
<%@ Control Language="vb" CodeBehind="CustomControl.ascx.vb" %>
<asp:Panel ID="myPanel" runat="server"></asp:Panel>
I'd lke to expose that panel as a property that I can use at design time.
CustomControl.ascx.vb
<ParseChildren(True), PersistChildren(False)> _
Partial Public Class CustomControl
Inherits System.Web.UI.UserControl
#Region "Members and Properties"
<PersistenceMode(PersistenceMode.InnerProperty)> _
Public Property SomePanel() As Panel
Get
Return myPanel
End Get
Set(ByVal value As Panel)
myPanel= value
End Set
End Property
#End Region
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Response.Write(myPanel.HasControls.ToString())
End Sub
End Class
And then bring the control onto a page like so:
<ucl:CustomControl runat="server">
<SomePanel>
<asp:Label ID="lblText" AssociatedControlID="txtBox" runat="server"></asp:Label>
<asp:TextBox id="txtBox" runat="server"></asp:TextBox>
</SomePanel>
</ucl:CustomControl>
When I run the page, HasControls is true but nothing is rendered. What am I doing wrong?
I am fixing issues in a project where I was not able to figure out a solution for the below problem. There are multiple user controls in Main.aspx page. First one is header.ascx which is added directly in .aspx page. and the others are added dynamically from Page_Init event. Basing on the hyperlink clicked from the menu on the left side of the main page, the respective user control is displayed.
Now, If I try to add script-manager/update panel inside any of the dynamic user controls, the respective user control page throws error. I have noticed that the header.ascx control is using scriptmanager. Is it creating the problem? How to handle this kind of issue?

I have a usercontrol which has a combobox inside it.
This UserControl is the inside an asp panel - and when the panel is visible, the dropdownlist within the control binds to its datasource and behaves itself.
When the panel visibility is set to false, the dropdownlist within the usercontrol is empty.
I have block of code that consists of a textbox a button and a dropdown. The text entered in the text box filters the dropdownlist when the user clicks the button. The Ajax works great when it is in a simple page but if I put the same code in a User control I get flicker.

I have a ajax tabcontainer which I load with tab panels at runtime. Now I am trying to do a fade in/out when a user selects a different tab panel. How do I approach something like this.
View 2 RepliesI'm having a bit of an issue in my ASP.Net application moving focus from a textbox in one user control to a text box in the next user control on the page after postback. I've searched high and low over the last several days to find a solution but, for whatever reason, have been unable to do so.
I have a page that has user controls loaded dynamically to allow a user to enter data.The number and type of user controls loaded to the page is determined at run time based on a database query.It is possible than many controls of the same type can be loaded. Each user control has its own update panel. Within the update panel of each control is a regular asp panel. Inside of the regular panel there are at least 2 server controls (any other controls that may exist in the user control are not affected by this issue) - a text box and a button.The defaultbutton property of the regular panel is set to the ID of the button within the user control. The desired behavior is to allow the user to enter data into the textbox on one user control hit enter to save the data on that user control the application will set focus to the textbox of the next user control on the page after the data from the "current" user control has been saved. Other considerations;
The application uses master pages. We make extensive use of ajax and the ajaxtoolkit in the application. I am using Visual Studio 2010 and .Net 4 The issue - when first entering the page, one can enter data into the first textbox and press the enter key. Data from "current" user control is correctly saved and focus is correctly moved to the next user control on the page.
Data can be entered into the textbox of "new" user control and when the enter key is pressed, the data is correctly save. The focus appears to move correctly to the next user control on the page.Data cannot be entered into the textbox of the control. Pressing the enter key will not save the data (because none was entered) but the focus will move to the textbox of the next user control on the page.
Data can be entered into the textbox of the user control. When the enter key is pressed, the data is correctly saved and the focus appears to move correctly to the textbox of the next control on the pageBasically, steps 3 and 4 are repeated until the end of the user controls on the page, alternating between being able to enter data and not. Other items of note When one is able to enter data into the textbox of a user control, one can correctly tab through the textboxes of each user control until the end of the page When one is not able to enter data into the textbox of a user control, pressing the tab key will take the focus to the address bar of the browser.
I created a much simplified example of the scenario described above and was able to consistently reproduce the "bad" focus behavior. All of the ajax toolkit controls and code where stripped out of the sample to rule the toolkit out as a cause. The behavior still occurs without the toolkit.
I am including the code for default.aspx and WebUserControl1.ascx.

How can I get all the textboxes inside a create user wizard control using getElementsByTagName().
Below is my JQuery code:
[Code]....
The above code isn't displaying hint text when the textbox retreives focus.
I think there is something wrong with this getElementsByTagName("asp:TextBox"); , I have also tried getElementsByTagName("TextBox"); , getElementsByTagName(":textbox"); and getElementsByTagName("input"); .
But no one of them gets the textboxes array.
Can anyone tell what will be the correct syntax for getting all the textboxes inside a create user wizard control using getElementsByTagName()?

View 2 RepliesI created a .NET user control to work as a DropdownCheckbox and added Jquery to give the sliding and hide effects. The code is as below:

This control works fine in a normal page, but once I put it inside an update panel it doesn't work. Is there a work around or simply I can't use JQuery inside update panel?
I am hosting a Windows User Control in my web page using <object> tag. Everything works fine when the control is outside the updatepanel and is independent of other web controls but when I move the control inside the update panel, it doen't load the user control properly.
<object id="myBrowser" classid="http:MyBrowser.dll#MyBrowser.UserControl1" height="20" width="400" VIEWASTEXT></object>
why it doesn't render the control properly and what can I do to fix it?
I tried moving the user control outside the update panel but since this user control is shown/hidden dynamically and is rendered based on other web controls which are inside an Update Panel, the user control is not shown at all.
I have a user control with linkbuttons (used for paging) and a repeater inside an update panel. The paging works correctly, but is causing a full page postback every time I click through to the next page.
The update panel looks like this:
[code]....
So far, I have tried adding an async postback trigger for the user control, which does cause an async postback but does not update the rest of the text in the update panel. In otherwords, the async postback occurs and the next page shows up, but the original text in the repeater is there as well just below it.
I have also confirmed that I have IDS set on my linkbuttons, since that can trigger a full postback inside an update panel.
I have tried changing the update panel mode (Always, Conditional, ChildrenAsTriggers, etc.).
None of it makes a difference - the only thing that actually causes an async postback is to use the trigger, but then the rest of the content in the update panel is not updated, so I get duplicate content.
