Custom Server Controls :: Create A User Control Which Takes XML As Input?
Mar 6, 2010
I'd like to create a user control which takes XML as input, applies an XSL transform on it, and displays the results of the transform in the web form or windows form in place of the user control. The transform should happen automagically when the windows form or web form is first loaded. I'd think this would be pretty easy to do. I just don't know how. point to a guide/tutorial on how to do this?

I have a user control (ascx file) that contains an interface for users to change the data retrieved from the db. So, I am displaying data and most of this data can be edited by the user. When the user enters text into a textbox, and clicks "Save Changes", the value they typed in is lost and not persisted to the database. I realize now this is because the SaveChanges button does a postback, and the user control gets reloaded with its original valuesbefore the code within my SaveChanges button gets executed. I'm not sure if there are properties I need to set to save the input data, or if I need to write my own code to do it. What is the generally accepted method to do this? (Also, all of the controls in the ascx file are wrapped in an Update Panel.)

I have a custom control which inherit from the Table class and in the constructor, it takes a an integer as an argument. There is no empty constructor.
Is there a way for the user to set that variable in the properties window after they drag the control onto a form.
I know some .NET controls, you can set the source for the parameter to different things like another control's property, QueryString using just the properties window.
Right now, I have to create the control dynamically. I read the query string and then created the object.

I have created a user control and am ready to convert it into a custom control. I am trying to follow:
[URL] the steps mentioned in the link.
I am not seeing Build / Publish Web Site option.
I am using VS 2008. I only see Publish User Control but it doesn't give all the settings mentioned below. When I do publish user control, it just copies the ascx file to the desired location. how can I convert the user control to custom control.

I'm new to all of this, so go easy on me. This should be an easy one. I have created a custom SmartContentBlock user control for a CMS.The control works, but only if I invoke the Fill() function in the Page_init event in the codebehind of the ASPX page. My goal is to modify the class file so that the Fill() in the codebehind is no longer neccesary. So, for reference, here's the gist of the current situtation.Controls.cs

I have a web user control that represents a simple message box. It is used to display simple messages like "Item has been deleted", or "The item was saved successfully".
On the other hand, I have another web user control that represents the item in the form of an editable form (I made this a user control because this is used in two different pages). I want to embed an instance of the message box user control inside the editable form. I am writing this right after the @Control directive:
[Code]....
Instead of using @Register directives, I register the user controls in web.config and so far this has worked just fine.
With the above markup, the project compiles, but whenever I try to navigate to a page that contains this construct, I get an HttpParseException exception. Furthermore, Visual Studio states that the tack w7rc9:MessageBox doesn't represent a known control.
What am I doing wrong?

I have a custom user control with some input fields and a submit button. I need to validate the fields using the jquery validation plugin when the submit button is clicked. (The function of the submit button is to create another custom control which displays the data entered in the above mentioned control)
Bt as far as I knw, validation plugin works only with form validation ryt? And my custom control does not contain a form tag as I am using master pages. The custom control is present in one of the content pages and the master page already contains a form tag with a runat=server attribute. And I guess one page can contain only a single form tag with runat=server attrib ryt?
So how do I get it to work?

I am using two user controls in my page. The controls are loaded dynamically one at a time. I'm just referencing the user controls in the page and loading them dynamically using 'LoadControl()'. Everything is working fine till now and the user can switch the controls one another.
Here the issue I found is eventhough the controls are working as expected and the data is visible, the rendered HTML contains only the first loaded user control's markup.
Even if the current control displayed is 'usercontrol2', the source shows 'usercontrol1' markup. How can I force the page to render 'usercontrol2' markup and remove 'usercontrol1' markup while loading'usercontrol2'?
