I'm trying to create a UserControl in ASP.NET to display news items based on two values that are passed in, NewsTag and ItemLimit. The problem is that the SQLdatasource is not picking up the properties in SqlDataSource1_Init. Instead the calls to the properties are empty when this is called but after render have values.
<script runat="server">
Public Property NewsTag() As String

I have a Windows Form frmMain() holding seven more-or-less unrelated UserControls, ucFlopsy", "ucMopsy", "ucCottontail", etc...I say "more-or-less" because each of the seven UC has three similar public read/write properties:
IsLocked (a boolean indicating if the following two properties are "Locked")
IsLockedID (if IsLocked=True then IsLockedID is an integer)
IsLockedName (if IsLocked=True then IsLockedName is a string)

Is there a way to expose a UserControl's properties to the Properties Window in the Designer?
View 3 RepliesI have a usercontrol that has a main form and calls another form within the usercontrol to get some data from a database that allows the user to select some items from a CheckedListBox control on the sub form. I want to pass the selected items from the CheckedListBox back to the main form and display the results there. I have a public property called DBList of type List(of String) on the main user control. If I create a reference to the usercontrol form the second form within the usercontrol I get a new instance of a user control. All I want to do is set the property on the usercontrol and close the secondary form. How do I reference the usercontrol from the form within the usercontrol?

I am trying to develop a control that'll allow the developer to populate a collection through markup (e.g. Properties decorated with the attribute PersistenceMode(PersistenceMode.InnerProperty). I have an example from Brian Chavez that more or less does what I want but I want to have the control inherit from UserControl and not Control.Here is the code I have in vb.net:

<PersistChildren(False)>
Public Class AggregateFeeds

As it is now when I try to compile I get a compiler error that simply says object instance not set to an instance of an object on the line above. If I take it out, the page loads just fine and the Settings object reflects the values in the markup. Why am I having trouble getting the collection to populate correctly?
I'm developing a form with usercontrols which have to be edited during disign.The project has a connectionstring in de my.settings.The usercontrol has a property which is also called connectionstring.Now, I want to pass the project connectionstring to the usercontrol connectionstring, when the usercontrol is dragged to a form.

Is there any simple way to hide all the design time properties of a User Control.
When my UC is on a form there's a lot of properties in the properties explorer. All those default ones that every UC has. AccessibleName, AccessibleRole, Anchor etc etc etc (dozens of the them)
Any way to hide most/all those and just expose my own ?
I suppose I want my User Control to be more like a 'Component' like the Timer and other components that don't have a UI. Short of rewriting my UC as a Component is there any quick way to hide all those form properties ?
Creating a usecontrol:
The control will have numberous properties available at design and run time.
I am having trouble creating and exposing FONT properties for the child objects.
Example: The control will have a label with a designtime and useradjustable Display font. I wish to
1) be able to set the Font attributes via the properties dialog at design time.
2) set those properties via GUI at runtime.
The problem...
Code:
Private propArtistHeaderFont() As Font
Public Property ArtistHeaderFont() As Font
Get
[Code].....
So clearly I can not pass the FONT properties back and forth via the SET/GET method.
I can create a Custom UserControl with simple properties (Integer, String, etc) and have those properties show up in the Property Panel. I can also create a Custom UserControl with properties like Size, Rectangle, etc and the properties will show up as an expandable item in the Property Panel (click on the '+' and the Size expands to Width & Height).
Is it possible to create properties with my own custom structure? e.g. Property 'Message' expands to Text, ForeColor, BackColor, Blink etc. I have tried creating a property that references a simple class or structure with containing the properties representing my custom structure but in the Property Panel the property is greyed out and cannot be expanded or modified.
I have a UserControl that has a Property - Text. How can I allow multi-lines of text to be created in its Properties (as a TextBox)

I have a class and method exposed to a client asp.net app. The class looks like
<DataContract()> _
Public Class Class1
Private v_string As String
Private v_integer As Integer
[code]....
The method is declared as
<OperationContract()> _
Function GetStuff(ByVal bar As Class1) As String
In the client code I create an instance of Class1 and set the values for v_string and v_integer, but using Wireshark to look at the xml being sent to the server only a value for v_string is being sent as part of Class1. I'm guessing this is because it considers the value of v_integer to be null/not set. Here is an example of the client code.
Dim MyService as New Service1.ServiceClient
Dim test as New Service1.Class1
test.P_integer = 1

how different types are passed/used since Integer is a intergral type and String is a class, but can't seem to work out what to do to fix the problem.
Passing data between forms without any public methods or properties on the forms. everything but the "Controller" class, which I would like you furnish. I just changed the title from "Intermediate" to "Beginner" This solution is an example of the Observer Pattern. The "Controller" class is the "observed" class, which in this case means it publishes events.
' File Definitions.vb
Public Delegate Sub MessageDelegate(ByVal sender As Object, ByVal e As MessageEventArgs)
Public Class MessageEventArgs : Inherits EventArgs
Public Message As String
[CODE]...
The program should initially display Form1, and Form2. Clicking of the button on either form will modify the Title Text of both forms. I think that you will find the final end result to be pretty neat, as it works with any number of open forms not just two. I think asking for the Controller class is easier than asking for the code in the forms. My solution for Controller class has 7 lines of content, 9 lines if you include Class, EndClass. A minimal solution could achieved with only 4 lines of content, but it would a textbook example of bad programming.
I have MainLayout.master that has UC_Menu.ascx on it. I have a page named Customer.aspx that uses MainLayout.master. Customer.aspx also contains a UserControl named UC_Details.ascx.How can I have UC_Menu.ascx call a function that is in UC_Details.ascx with this scenario?
View 3 RepliesI have a Windows Form that contains a custom control container as a UserControl. For the sake of this question, this custom control container is called Dashboard. This container called Dashboard contains numerous other controls depending on their permissions. I need to raise events that are contained on these controls through the Dashboard control and over to the Windows Form.
How can I bubble up the event? I'm using VB.NET for this project, but can convert C# into VB.NET.Also, to complicate matters, the main Windows Form is a VB6 project. So, I'm using the InteropFormsToolkit to accomplish this.
I have two UserControls on a MasterPage. DataEntryUC contains several TextBoxes and DropDownList. NavSaveUC contains navigation buttons. When the user clicks on a navigation button, I will be saving the data entered into DataEntryUC from the NavSaveUC UserControl.

I just discovered the joys of UserControl's and I was wondering if it is possible to populate the usercontrol with data from a database in the UserControl's Form.Load event instead of the form the userControl is placed on. I feel it would make using the control a lot easier if it just populated itself without anymore code.I tried it with a ListView but it gave me a bunch of errors, so I didn't know if it had to be done a certain way or if it was just one of those things that doesn't work no matter what.
View 8 Replies[code]I want to make the Properties Window to update the properties for X and Y at each MouseMove, so they become immediately visible for the user.
View 2 RepliesI'm making a control and I am trying to finalize my design time properties grid. I have several List(of Class) items as public properties and when I click on the design time menu (while testing the control) there is the word "Collection" and a button with an ellipsis (...) that brings up a neat pop up with the buttons Add/remove and all of the public properties of the collection's class on the right hand side. Basically for a non-collection instance of a class (with public properties) I'd like a similar button to show up. I know I could put all of the properties in the main control class and group them, but I like the pop up box feature. Anyway to duplicate this? (think font grid item etc.)
View 3 RepliesIn the form design I set up a TableLayoutPanel, 20x20 cells and in cell (1,1) a PictureBox (called Target) containing the image of a small target. The properties box for Target shows some very promising properties, Column and Row - and if you overwrite the values in the properties box, the PictureBox obligingly shifts to the corresponding cell position in th design. However in VB it is not possible to refer to Me.Target.Row or .Column - neither appears during coding in the menu of properties, and deliberately coding either of them produces an error like
Error 1 'row' is not a member of 'System.Windows.Forms.PictureBox'.
1. Why does the properties box show properties that cannot be altered programmatically?
2. How can my program move Target around in the TableLayoutPanel?
I'm working on a Hazardous Materials label printing program. One of the options is to do an "NFPA" label. Since there are 4 values required with 4 or 6 options, the ratings are entered via radio buttons in a group box. That's working okay. I display values in the NFPA diamond as they're entered: left quadrant blue, top quadrant red, left yellow, bottom red. I'm having trouble with the label in which the rating will be displayed on top of a jpg diamond for the white. In this quadrant the text can be up to 4 characters. I can accept the text going into an adjacent block a little, but the corners of the label overlap into another quadrant/color. I reduced the font size which solved the overlap problem but the font is then too small and looks terrible. I tried to make the background of the label transparent to let the color come through correctly but that's not a valid value for label.background. I'm figuring that the transparent background is the best solution. What can I use that will accept a transparent background so the color shows through?
I'm trying to set the transparent property via label properties properties, not via code. Here's the code if it makes any difference:
Public Class NFPA
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Close()

What I've done is create a User Control Library (Project) and I've added a single User Control to that project. The control contains a single FlowLayoutPanel, and I created a Property on the control itself to pass the FlowDirection from the Control to its FlowLayoutPanel child.
Build, reference, component appears in the Toolbox and everything works fine, but the property on the control does not appear in the Properties window when I go to edit it at design time.
I have a BLL class which contains properties for the fields in a Country table (CountryCode, CountryName, etc). It also has a property ioDAL, which is a reference to a DAL class (created with SubSonic 2.2), which has same named fields.
I have a LoadRecord() method which calls the DAL's FetchById() method that populates the DAL properties by calling the database (SQL Server 2005 FWIW).What I then want to do, rather than writing code to populate each BLL property from its DAL equivalent, is to use AutoMapper (from CodePlex). I think the line should be something like
Mapper.CreateMap(ioDAL, Me)()but this gives errors "Value of type (DAL class / namespace naming) cannot be converted to 'System.Type'" and "Value of type (BLL class / namespace naming) cannot be converted to 'System.Type'".
