Web control in web control
Hi,There are two simple web user controls A and B, where B contains A. They just display the bunch of text boxes, so I do not need them even in tool pane. They sit in the same project next to web form.I noticed that web user control put on ASPX page does not appear in code behind, but if I create it with protected keyword and name being exactly the same as id it works fine. I can access such a web control from code behind and see the value assigned in IE. The problem is that the same routine does work for my A web control in B. When I assign the value IE, I keep getting null reference. ...
Controlling web control instances on Web Form
I have created a composite control, extending functionality of the Hidden Control. However, I would like to prevent the user from adding this control to the page multiple times. I only want one instance of the control on the Web Form. What setting in my project to I adjust to enable this functionality? I can not find it in any of the books that I have referenced. Is this a setting or is this code that has to be added to the inheriting class.
Looks like there is no standard apporach. But I'd consider using static field to count number of created objects and throw exception if second object ...
Use Web Custom control or Web User control?
Friends, I have a generic aspx page and its functions which is used in many .NET web application. The generic page contains a HTML Div control, server drop down list, server buttons, server textbox and it have different server and client functions to do its tasks for calling aspx pages in web applications.
My problem is I do not know whether I should make that generic page as a web user control (but this is tedious because all other application folders must store frontpage aspx and code behind files of the generic page) or as a web custom control (This seems to be good beca...

the web control event should be handle in the code behind page, is the event handler for the button you are clicking registered? You can try double clicking the button, should give you the default btn_click event handler in code behind.
Also, make ...
controlling an object in a web control from the page the web control is placed in
I have created a web control in vb.net that has an image button and an image. when it loads the image button is visible and the image is not.
I want to be able from the page which "includes" the web control to set the image button to invisible and the image to visible.
When I tried this, the main page didn't recognise the image button or the image (both < asp: objects).
help would be gratefully appreciated.
oh yeah, it's inline code so any code behind stuff will just confuse me ;)
Some code please.-- Justin Lovell...
I have a web user control being used by another web user control, but the one being used will not display the labels in the resx file.
I am using DotNetNuke version 3.13 (might be 3.013) on a Window's XP machine, SP2. I have what I find to be an extremely odd situation. I have a project called TDS.Controls. This project is a web control library. Each control has its own resx file, which is located in the App_LocalResources directory. Each control inherits from Framework.UserControlBase, just like DotNetNuke's User control in DNN\Controls\User.ascx.vb. As a matter of fact, this control is doing the exact same thing I am trying to do. It is a web user control with its own resx file being used by another web user control (See ...
How to use a web user control from one web app in another web app?
I have a production web app project (at work) that has custom web user controls in it.I have another web app project for experimenting and I want to use some web controls from the production web app. The big trick is that I need to load the controls dynamically.LoadControl() doesn't seem to work - it complains about loading controls from a different application. I also tried adding a project reference to the production web app and using "UC1 newUC = new UC1();" and then "this.Controls.Add(newUC);", but the controls (like TextBoxes) on the web user control don't seem to exist on the new UC1s....
Web User Control to Web User Control...
Hi, I have 2 User controls on a page and want Control1 to call a method of Control2. Is this Possible?
Example:
Con1 = Datalist showing products, each with a Quantity Box and a Button.
Con2 = Repeater showing Cart Preview (name, Price)
in page.aspx.
When I click on the button on the DataList in Con1 it adds the item into the Session based Cart. However it does not update the Cart Preview. I need to call BindPreview() in Con2 in order to update the Cart Preview...
Does that make sense? argh! any help much appreciated!

Reusing custom web control in the same web control
Hello,
I'm newbie in web development and of course asp.net. I am actually trying to build my first page and I'd like to know if it is possible to make a custom webcontrol that will contain itself. Let's say I want to draw a folder hierarchy in treeview-like structure. I thought I could make a control that will display a folder and if this folder contains subfolders then for each the control will include itself. Is this even possible? What would you suggest me to do to?
Thanks in advance.

Mobile Web Controls vs. Web Controls
I am using VS2003 and I have realized that Mobile Web Controls are very basic and simple.
So I saw in a post the way to use Web Controls inside Mobile Web Forms. Since then, I often use Web Controls instead of Mobile Web Controls.
I put the Web Control inside a Mobile DeviceSpecific and put this DeviceSpecific inside a Mobile Panel.
Why the Mobile Controls are so simple? Does it happen the same in VS2005 or 2008?
And, is it right to use only Web Controls inside Mobile Web Forms?
Thanks.

Web Form and Web User Control
Hello,
I have a Web User Control (ascx) that includes a button. This button has an onclick event method.
This Web User control is included into a Web Form. (thru LoadControl).
However, when I click on the button, the event method is not executed.
What should I include in order it works fine?
Thanks in advance.

Using Loadcontrol is using dynamic controls and when using dynamic controls you must recreate the same dynamic controls ono postback to econstruct the page control tree. It is best if you do this during the Page PreInit event.
