C# - Setting Property Default Values For A Web User Control?
Apr 15, 2010I am trying to build a web user control and set some default values for its properties in the code-behind like this:
[DefaultValue(typeof(int), "50")]
public int Height { get; set; }
[DefaultValue(typeof(string), "string.Empty")]
public string FamilyName { get; set; }
[DefaultValue(typeof(Color), "Orange")]
public System.Drawing.Color ForeColor { get; set; }

Databind A Property On A Custom User Control?
Nov 29, 2010I have a custom user control UserProfileLink on which I have two basic string properties, UID and UserFullName which I would like to use in a template column in a DataGrid like this:
....
<ItemTemplate>
<td:UserProfileLink ID="uplUser" runat="server" UID="<%#Eval("UserUID") %>" UserFullName="<%#Eval("UserFullName") %>" />

Custom Server Controls :: Category Attribute Of User Control Property Does Not Work Correctly In Categories Tab
Aug 19, 2010I 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?
Accessing Property Value Of A Custom Control By Another Custom Control In Design-time
Oct 18, 2010I 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 :: List Property Of A Custom Control Is Not Persisted?
Mar 15, 2010I 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.

Setting A Server Control Property From The Content Page?
Oct 27, 2010I need to validate a textbox to ensure the submit date is older than Today. I wanted to use a CompareValidator to do that, but unfortunately the following code doesn't work:
<asp:CompareValidator ID="cvtbDateExpiration" ControlToValidate="tbDateExpiration"
Operator="GreaterThan" Type="Date" ValueToCompare="<%= DateTime.Today %>"
ErrorMessage="Card has expired" runat="server" />
The compiler tells me that ValueToCompare="<%= DateTime.Today %>" is wrong: "This is not scriptlet. Will be output as plain text."
Is there a simple way to achieve this (without setting it using the Code Behind)?

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, 2010I 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.
