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.

Accessing Property Value Of A Custom Control By Another Custom Control In Design-time

Oct 18, 2010

I created an Extender which has a custom property that drills down a list XML elements from an xml file, where users can select xml elements during design-time. This works perfectly fine. However, my code only has a hardcoded xml filename (source of the xml elements list) and I need to change this by maxing the xml file user-specified.

What I did is that I created another control (panel) which has a custom property that when clicked (through the ellipsis), it will allow a developer to select the xml file which is supposed to be the source xml file that the Extenders shall use. The filedialog from custom panel's property works perfectly fine.

However, my problem now is that when I drag-drop my Extender, I cannot find a way to get the property value of the custom Panel Control which contains the xml filename. I tried creating a static variable which I thought the custom controls can share but VS2010 is breaking.

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 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.

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 :: Category Attribute Of User Control Property Does Not Work Correctly In Categories Tab

Aug 19, 2010

I have a User Control (ascx) and a property which a want to display in my categories tab in Visual Studio in the category named "Styles".

[Code]....

And here is the problem: Actually I do not need a get, because I only have to set the property (write only property). But when I omit the get, the property is displayed in the "Misc" category in the categories tab in Visual Studio. Only when I code the get as well, then the property is displayed correctly in the "Styles" category in the categories tab in Visual Studio.

Does anybody know why? How can I display the category correctly only with set?
