View 2 Repliesis it possible to create kind of widgets that are pluggable in ASP.NET MVC? I'd like to give my users the option to upload and attach a widget that I provide (ie. zip format). Recently I thought about deploying Areas in different project assemblies. Is it still possible with MVC RC2 (later RTM) and is there an option to dynamically attach that areas (say from a admin panel)?
Second question, how would you guys create a dynamic layout where admins could select widgets to display, arrange them, disable, move them etc.? I mean a flexible layout that can be changed via the admin panel without having to touch the code. Here I thought about defining and storing layout widgets paths in a db. Later I could associate these widgets with routes (in db). For each request (controller, action) I would fetch the layout among with associated widgets and output them recursively. Probably I could user RenderAction and PartialViews for that.s my direction correct or should I focus on some other technique?
I need a way to create unique values for a property in my custom server control..
In this case I will have the poroperty called "Name" and I neeed the value of Name to be unique for each "instance" of the control...
So for instance if I have a page with more then one instance of the control, I dont want the value of the Name property for these instances to be allowed to be the same..
...to put it kind of simple, if I dont remember this incorrect, I want it to be sort of like the ID property..but with another name then ID.
How to create a user control for this kind of layout. I have a css. But dont know how to create a control for this kind of display.

i have written the required properties which are working fine except the "checked" property. here is my code for 'checked' property. i tried both the below ways (commented one and not commneted) . the problem is the 'checked' value is not setting the value at the get set part of the property.its assigning the value at the design time , but when i check and uncheck its not updating the property value.which is resulting me wrong .

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.
I need to create one custom text box control which should be bind with data base.
I am referring following link...

public class SimpleTextBoxControl : DataBoundControl

private TextBox nameTextBox;
public string DataTextField

get
{
object o = ViewState["DataTextField"];
return ((o == null) ? string.Empty : (string)o);

set
{
ViewState["DataTextField"] = value;

}
[
Bindable(true),
Category("Data"),
DefaultValue(""),
Description("The text to display on the link."),
Localizable(true),
PersistenceMode(PersistenceMode.InnerDefaultProperty)

public virtual string DataTexValue
{
get
{
string s = (string)ViewState["Text"];
return (s == null) ? String.Empty : s;
}
set
{
ViewState["Text"] = value;
}
}
protected override void PerformDataBinding(IEnumerable retrievedData)

if (retrievedData == null)
return;
base.PerformDataBinding(retrievedData);
Controls.Clear();

I have created an asp.net custom control and now want to pass some values to it from the page which will use the control.Is there any way i can add my own property to the control (like Text property is present for a Label control)?
View 4 RepliesHow would I add a (dropdown) list of available values for a custom server control property?
(Just like 'Visible' property of most controls has valid values of 'True/False' and nothing else can be entered or selected)
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.
I have some (probably very basic) questions about developing custom controls. I am wanting to derive a set of button controls, and the first one I have started on is a "DeleteButton", that has a additional property (DeleteConfirmationText) that is built into the OnClientClick attribute. To get that added, I overrode the Render method as follows:
[Code]....
This all works well. Now, I will add some logic to make sure that there is some text in the DeleteConfirmationText property, but that isn't the intent of my question.
What I am also wanting to do is to override some of the default property values, so I added that to the default constructor:
[Code]....
Now, in the designer in VS2008, and I look at the properties for the control, there isn't a default value shown in the "Properties" section, and the Causesvalidation still shows the underlying classes default value of "True". As well, in design mode, where the GridView control that containse my DeleteButton control would be displayed, there is an error box "There was an error rendering the control. 'Are you certain you want to delete this attorney?' cound not be set on property 'DeleteConfirmationText'. Here's the markup where I am defining the deletebutton control:
[Code]....
What am I doing wrong?
I want to create a custom control where I define several specifically named DIV sections. The code-behind logic of the custom control will perform operations on these named DIV sections. The page where the custom control is hosted needs to be able to add named controls to the DIV sections and perform operations on these named controls added to the DIV sections.
Let me explain a little further. In the custom control, I want to have code behind logic that fires the following Page Event and uses a condition to make one or another specifically named DIV section visible or not:
< _
ToolboxData("<{0}:BaseDetails runat=""server""></{0}:BaseDetails>") _
> _
Public Class BaseDetails
[code]...
how can I create a custom control which is able to generate the named DIV sections "DetailsNameDiv1" and "DetailsNameDiv2" where my custom control can check a condition and make one or the other visible. Also, I need to be able to add controls to these named DIV sections when I host the custom control and the control that I add to the named DIV section needs to let me set values of these controls from the code behind logic of the page (or usercontrol) where the custom control is being hosted (in my example, I am adding TextBox controls that I want to set the Text property from a SQL Data Reader).
I have currently on multiple pages a modal popup that displays the information below, we are getting to the point where we need to call this popup from multiple locations, currently i have duplicate setups on each page that i want to use it on, but its becoming a mess to manage when a change is needed.. so im looking to see if what i have within the modal popup can be turned into a control that i can call anywhere thru out the site and have just 1 setup to maintain going forward..If its possible to create a control that can then be placed within the modal popup and server the same purpose that would be great any links here is what i have within the modal popup that i have on atleast 3 pages currently..
