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 :: Custom User Control That Fills Itself?

Feb 15, 2010

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

Custom Server Controls :: Paging And Sorting Gridview Custom Control Inside Of A Wizard Control?

Dec 24, 2010

here's a situation and I would appreciate your response.

I have programmatically created the Wizard control:

Page_Load(obj s, evargs e)
{
Wizard ClaimDetailWizard = new Wizard();
foreach(int item in selectedItems)
{
//create new step
//added custom control to new step
//add step to wizard
}
//added wizard to a placeholder on a page
}

Based on List I get from Session i added new steps to my wizard To each step I had added a custom control

Each custom control in tern contains another custom Gridview Control in it.

So here's the problem when the page loads for example for two steps. All is good Wizard does what it's supposed to do.

But when I try to use sorting or paging in that custom Gridview. Somehow it displays the gridview I should see in the next step of the wizard.

Also what I'm noticing through debugging. Is that when I press next in the wizard I go back to the original page where I do all of the code specified above, and it recreates the wizzard. But it goes to the next step. Is this the way wizard supposed to work? Just doesn't seem very efficient.

Custom Server Controls :: Add This Control To The Page,an Alert To Check The Text Value Of The Custom Control?

Dec 20, 2010

created a Custom Textbox Control that is intended to be a "masked date" textbox, so that I can handle different ways a user might enter in a date and make it work no matter what.I did this by creating a custom control with 3 separate Textboxes one for month,one for day one for year,then do some handling for different things that could be entered and it would all work.

The problem I am having is,when I add this control to the page,if I do an alert to check the Text value of the custom control it just gives me "[ServerControl1]" even if I enter in a date.

I tried doing an AutoPostback after entering so that it would refesh the Viewstate to have the values of the textboxes but the control doesnt seem to actually postback, even though I have it enabled.accessing the Textbox value after someoen
has entered a date?first custom control I have created and have been using google.

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?

Custom Server Controls :: Custom Composite Control With Custom Templated Child Controls?

Mar 22, 2011

I am trying to build a custom composite control, which allows me to add custom content to each child control. It's a similar concept to what you have with a GridView and TemplateColumn. The markup used to place the control on the page would end up being something like this:

[Code]....

I have the code below, which allows me to put that markup on the page without throwing any errors, and it renders all the correct HTML, except it doesn't render the contents of the ColumnTemplate. I have replaced the Render() code with a comment because it's quite long winded and doesn't add anything important here:

[Code]....

I have tried to follow examples on MSDN and other forums but I can't make this work. I think I'm missing the code to render the contents of the template, but I don't know how to hook that up.

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 :: Custom Control's Children Do Not Persist Contents After Postback

Feb 25, 2011

I have created a really simple custom control to render panels into a page. The code is below. When I use my control and add any webcontrol to it, after each page postback the contents of these child controls vanishes.

I must have missed something really simple but run the example to reproduce this. Can anyone please enlighten me as to why the controls are being 'emptied' of their contents, and how I stop this occuring?

Here is the code for the control

Custom Server Controls :: Implementing An Interface From A Class Library In A Custom Control?

Jul 8, 2010

I'm building an n-tier application, with the web client and the class library separate. I'm also using the factory pattern of development, using interfaces to act as containers for different objects they are associated with. The problem I'm expreriencing is that I declared a public interface class in the class library and I can create an instance of it in in my aspx pages but whenever I declare it in my custom control code-side, i get an error, like so:

Error 20 The type or namespace name 'IContentMaker' could not be found (are you missing a using directive or an assembly reference?)

notge that I have inherited the class library namespace using the 'using' keyword just in case you are wondering. My code is like so:

using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
using TQO_Classes ; //importing the class library project
public partial class PageContentMgr : System.Web.UI.UserControl
{
private IContentMaker _data; //this line throws the error, it works fine on aspx pages

Custom Server Controls :: Custom Control Design View Error

Aug 13, 2010

I have created a custom control from scratch and it works fine as in you can build the project that uses it and it works fine at runtime. Problem is when you go to design view the control shows an error in the place of where the control should be rendered.

Error: '<SomeValue>' Could not be set to '<SomeProperty>'

This shows up on all my custom set properties. These properties are created as basic as possible. I can give the properties values in Source view and run the app just fine. I can even add a Onclick event. If I don't set any custom properties the control will render fine in Design view. It's only when I set a value to a custom property.

Property Code Example:

I've even removed the Category and Description tags with no difference.

I don't know if what I said makes sens, but I hope it does.

Custom Server Controls :: List Property Of A Custom Control Is Not Persisted?

Mar 15, 2010

I have a custom control, inherited from Button. This is the class definition for the control and 2 properties:

[Code]....

I show you 2 properties, only to illustrate the problem.

as you see Aplicacion property is of a custom type Sistema, and Roles property is of type List<UserRol>.

The Aplicacion property is rendered well, this way:

[Code]....

The problem I have is with List<UserRol>. I couldn't get it to be rendered. I expeect to be rendered this way:

[Code]....

Finally, this is the TypeConverter and Editor definitions for the list:

[Code]....


The UserRol class is a typical class, without any special attributes.

I have discovered that when I use the custom editor for Roles property, the collection is not persisted. When I use the default editor for the collection, the collection is persisted.

Custom Server Controls :: Pass Javacript To Custom Control With ClientID?

Sep 17, 2010

I have a custom control that I have created. I want to be able to pass in a Javascript snippet for a callback function. I am able to do this by passing a string back. The problem is that in the Javascript, I need to reference another server control that is not related to my custom control. So, I need to be able to pass in the ClientID of that control for use in the Javascript. Here is a snippet of what I am trying to do:

[Code]....

Now, I realize that '<%= chkStartDate.ClientID %>' will not be parsed. But, I need it to be parsed so the OnClientOnChangeEvent property of my custom control can take any Javascript for use as a callback. In this instance, I need to pass in the ClientID of the control for the Javascript function to find the control to work with; and this seems to be the one issue that I don't know how to handle.
