user controls

Author	Message
John Gor #1 / 4	user controls I just created my first user controls and I am quite e{filter}d to see them working. However, I would like to have descriptions of the properties appear when the devellopper clicks on a property in the properties window ( at the bottom of the property window just like any other standar property) and when they are selecting the property from the drop box ( when you type datagrid1. you get a set of values and you can choose from the list and as you go down the list you get a little message explaining what the property does) I am not sure this will make sense to anyone, but if it does the help would be deeply appreciated. BTW, how can I cancel a keypress , I assume it is in the keypress event but I see no way to cancel it there. Thank you very much Jonn

John, What you need to do is put an Import statement at the top of your code file for the System.ComponentModel. Then you will need to use Attributes (Category, DefaultValue and Description) above your property. Here is an example for you: ********************************** Imports System.ComponentModel .... Private m_MyProperty As String <Browsable(True), _ Category("Your Category Here"), _ DefaultValue(""), _ Description("Indicates a file to use for " + _ "design time puposes if an InputTask is not specified"), _ Public Overridable Property MyProperty() As String Get Return m_MyProperty End Get Set(ByVal Value As String) m_MyProperty = Value End Set End Property ********************************** Also, there is a more info in the helps file regarding these and many other Attributes. The best way to search for them is to append the word "Attribute" to the end of them when searching such as: "CategoryAttribute" Typing the full name is optional when using Attributes in code though. Hope this helps, Cal

John, One other thing I just now noticed is that you are also wanting the tool tips on the Intellisense drop down list. At this time, it is only possible from C# and not from VB.NET. As for you last question regarding the keypress event, you need to set the KeyPressEventArgs parameters "Handled" property to True as in the following code: Public Class MeTextBox : Inherits TextBox Protected Overrides Sub OnKeyPress( _ ByVal e As System.Windows.Forms.KeyPressEventArgs) e.Handled = True End Sub End Class Once again, hope this helps.
