Does A Composite Server Control(inc. User Control, Custom Server Control) Normally Encapsulate Css Properties?

Nov 7, 2010

If a composite server control normally encapsulate styling information inside, it is an example of code encapsulation and modularization. However if css properties are included inside the composite control, it is not ideal for code/styling separation and css code re-use principles. Now which consideration should be the main consideration?

Custom Server Controls :: Composite User Web Control - Properties - Best Practice

Jan 12, 2011

I would like to ask you what is the best practice for developing composite user web control with multiple controls inside from the stand point of dealing with properieties. In my situation I would like to use header menu bar with logos, buttons, java baset visible/hidden menus itc as web control. I was successfull in implementing new control in my project.

But my question goes to issue of properties for ALL OF controls. I know how to hard code all required properties like: text, visible, enable for all controls. It's a lot of work. ( This is the very edge of my asp.net comprehension ) Is there a more elegant way provide an access to controls's properties without hard coding seperatelly?

Custom Server Controls :: Custom Control's Constructor / User To Set That variable In The Properties Window After They Drag The Control Onto A Form?

Mar 4, 2010

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.

Custom Server Controls :: Composite User Control Cannot Be Added To TableRow Dynamically

Jan 21, 2011

I have a composite user control consisting of three standard table cells (a legend, an image with a tool tip, and a text field control). If I add these to a TableRow in my aspx page it works fine and produces legal HTML in my source. The below works fine ...

<tr><MyControl:dataField
ID="txtEmail"
DataType="Email"
runat="server"
/></tr>

However when I try to do the same programmatically (C#) the TableRow won't accept anything in its Controls collection that isn't a TableCell. I could make my control a nested table in its own right but I lose the alignment of my form items on the page with multiple controls, as each table aligns itself according to its contents. Is there anyway I can make the TableRow accept my control as collection of cells or do I need to do some casting or making my user control inherit some kind of TableCell attributes? I can also dynamically add my controls to a TableCell item which actually displays OK in IE but creates illegal HTML (<td><td></td><td> ... </td></td> - I assume this is illegal) in my resulting source. The code below DOES NOT work ...

Custom Server Controls :: Accessing Properties Of A User Control From The Inherited Code Page?

Mar 8, 2010

If the answer to this question exists somewhere, I'm no good at searching for it. This is sort of a simple question, the response being two parts: (1) is it possible? (2) if so, how?

I've created a web user control for my site's footer. In my web.config I have it registered like this:

[Code]....

Then, within the pages on my site, I simply insert it like this:

[Code]....

But obviously, that didn't work. I get this error: The type or namespace name 'FooterControl' could not be found (are you missing a using directive or an assembly reference?)

So I'm really not sure what to do at this point. I can put all of my code in the ASPX file and make my life easier, but I would kind of prefer not to.

How To Expose Child Control Style Properties In A Custom Composite WebControl

Feb 23, 2010

I am writing a custom composite WebControl and want to expose styles of child controls it encapsulates to the ASP.NET designer. The code I currently have is similar to the skeleton below (which for simplicity only has one child control).

With the code below, I can see property "ChildPanelStyle" in the designer, but when I try to modify one of the properties (e.g. CssClass) in the designer, it immediately resets itself to its default value. It looks like the designer serialization isn't happening.

What am I doing wrong?

UPDATE

I've updated the sample with an additional style property that is managed directly by the custom control, rather than simply being the property of a child control.

The HeaderStyle property is persisted properly by the designer, but the ChildPanelStyle property isn't.

Of course I could manage all my styles like HeaderStyle, and apply them during rendering, but I'm hoping there's a simpler solution whereby child controls can take care of themselves, and I don't need any custom rendering.

Custom Server Controls :: Composite Control - Mismatching The Result?

Nov 3, 2010

I am creating a composite control. On the selection of item in the dropdownlist, the result should be shown. But its mismatching the result. Here is the code for the control:

[Code]....

If I have a breakpoint on the selection index changed event of the dropdownlist, then on every selection it should go to the event. Problem is when I select an item which makes the "singlelineText" textbox to appear and after it I select any other item, it doesn't stop at the dropdown event instead it goes to the "CreateChildControls" method of the composite control which results in wrong data.

Custom Server Controls :: Making Phonenumber Composite Control?

Mar 17, 2011

I am trying to make a PhoneNumber Control. I inherit from Composite Control. It contains 5 controls : 1 Label (Text to show before), 3 TextBoxes(area, prefix and line) and a Custom Validator. What I want to happen is the validator to validate the control is belongs to in two ways: 1. that the field is required and 2. That the COMBINED text of the 3 textboxes is 10 digits. I believe i can accomplish this with the expression ^d{10}$. Now I have it about halfway working, it will validate the control using client-side
embeded validation on a submit click, however I need the control to validate as soon as the text of any of the boxes changes. I know this is done on the aspx page by using a Custom Validator -> specifying client and server side validation functions -> and then at end of page doing ValidatorHookupControlID(control, va lidator). My goal is to do all of this within the control to clean aspx code and make it more reusable.

Custom Server Controls :: Trigger Click Event In Composite Control?

May 10, 2010

My CompositeControl creates dinamically several RadioButtonLists according to the DataSource information. These controls are added to the Controls list and rendered in CreateChildControls event.

I need to create a LinkButton that clear a specific RadioButtonList selection and do a postback, to load the DataSource information again (some selections changes the data that need to be loaded from the database). For each RadioButtonList, I've put a LinkButton and assigned the Click Event to a method inside the same CompositeControl, to do the RadioButtonList cleaning.

Unfortunatelly, the LinkButton doesn't trigger the Click Event. In HTML code, the link has the "onclick" attribute setted with the asp.net event, but when clicked, nothing happens.

In fact, the designer class is a copy of a sample class in MSDN and I only tried to customize it to work for me. I'm not sure if all methods are necessary or not.

I have the following two questions:

Custom Server Controls :: Unable To Use A Web User Control Inside Another Web User Control

Mar 10, 2011

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?
