User Control Properties Intellisense

Sep 30, 2011 03:09 PM|LINK
Hi,

I've created an user control in a ascx file.

I've assigned some properties to that control, something like this (Title):
```
private string _title;
/// <summary>
/// Get or set Title of my grid panel.
/// </summary>
public string Title { get { return _title; } set { _title= value; } }
```
When I add my control in an aspx page and register it in the aspx page, I can list all properties like 'Title' of my control using intellisense support.

For some other properties of the control, I'd like to have a kind of list of allowed value for these properties, the same that happen for example for the columns of a grid view. When you have a grid view in your asp.net page and start typing '<', you see that the intellisense shows allowed values, for example AlternatingRowStyle, Columns, etc...

If you select Columns, you can see that the intellisense shows you a list of available values you can choose, for example asp:BuondField, asp:ButtonField and so on.

Do there is an example of the code somewhere that shows how to create for an user control having some properties with a list of available values that are showed by the intellisense?

I hope the question is clear.

Thanks

hi ,

if you mean a Template like this:

<uc:usercontrol1 id="uc1" ..................>

   <Title>

      some soms omsome some

   </Title>

</uc:usercontrol1>

you can use this links : Link1   , Link2

and if you mean that the Title Property have many Values , you declare this Property as Enum of Values like this :
```
public enum Values {
            Some1 ,
            Some2,
            Some3
        }
        private Values _vals;
        public Values Title
        {
            set
            {
                _vals = value;
            }
            get { return _vals; }
        }
```

Hi,

thanks for your quickly reply.

It is not enough. I try to explain.

Whit the code you suggested, if I include my user control in a page and if I I start to type: 'Title', the intellisense suggest me all the value allowed for that property but it is not the goal.

I would have the following situation. Consider the example showed in the Link1, when I add the control in the page and when I a start to type MessageTemplate and close the tag, then I would receive fron the intellisense some allowed value for MessageTemplate node and I would customize this kind of allowed values.

Example:
```
<uc:TemplateTest runat="server"> <MessageTemplates> <MessageTemplate SomePropertiesForThisMessageTemplate /><MessageTemplate SomePropertiesForThisMessageTemplate /> </MessageTemplates> </uc:TemplateTest>
```
It is not easy to explain, I can give you an example of a library that include some controls with this behaviour (Ext .NET www.ext.net). If you see the example Editable Grid Panel (http://examples.ext.net/#/GridPanel/Editable/Editor_with_DirectMethod/), you can see that for the component

<ext:GridPanel...

you can have the properties Listener like this
```
<Listeners> <KeyDown Fn="startEditing" /> <AfterEdit Fn="afterEdit" /> </Listeners> 
```
that is the goal.

I hope it is more clear now.

Many thanks

I'm afraid I don't have any samples of this, and perhaps you can check with our All-In One Code Framework site - that is a good place to go to ask for samples such as this.

I think it's called a control collection, I forget, but I know what your talking about. There are very few examples on the subject.
