How do I inherit an existing control (user control) and add it to the ToolBox?
I have UC that inherits a textbox. It is meant to only accept numeric values. I want to be able to add a property to give the end user the choice of setting the FORETCOLOR to another color other than that which they have chosen for the normal FORETCOLOR settings. Is there some line of code that will allow me to access FONTCOLOR dialog box when a user clicks the FORECOLORNEGATIVE property setting in the Properties settings?View 6 Replies View Related
I am trying to create a custom control and put three of them on the main form of the project. I have the control made, but I can't figure out how to add it to the toolbox.
Note: I am using Visual Studio 2010 EXPRESS EDITION. I don't know if this matters for something like this, but I thought I should probably mention it.
I know how to get a user control into the toolbox, but is there a way to get it to be part of vb.NET's startup as a permanent control? In other words, if I start vb.NET and begin a new project, it would be nice that the custom control is already available without having to load its dll each time I start a new project.View 3 Replies View Related
I am building an application in VS2008 (VB.NET) that contains several user controls. When I was developing under VS2005, all the components in my application would load into the toolbox so I could access them during design.
Since upgrading to VS2008, however, those application-based components do not load, and I cannot access the user controls I have built.
1. Exit Visual Studio
2. Navigate to %USERPROFILE%AppDataLocalMicrosoftVisualStudio9.0
3. Delete the TBD files found there (these are hidden by default)
4. Re-start Visual Studio and open your WPF application - the toolbox will now be reinitialized
and that worked for one session, but it did not get preserved -- when I shut down and came back into VB.NET, the application-based controls no longer loaded.
Is there some setting in VS2008 that I am missing? Or is there another step to getting the app-based controls to reappear each time I load the development files?
I would like to be able to set Control visual properties such as color, boarder, flat style, etc. on the base class of the control so that as I add new instances of the control, each instance inherits the visual properties of the base. I have tried using Application Settings but it appears as though I need to reference an application setting manually each time I add the control to a form. This is a Windows Form question.View 4 Replies View Related
I've got an existing asp.net project written in vb.net. Another person has written a user control in c#.
let me know the steps for adding that C# user control to the vb.net app?
I've tried copying them to the folder and using "Add existing item", however it doesn't compile the code behind at all.
Does VS 2008 have a control availible like the toolbox control from within the studio? I've looked through the list in the toolbox for choose items and am not finding it, but since I don't know what it would be called I might be over looking it.View 3 Replies View Related
Can a custom control NEW Sub be the only one that executes when Inheriting from an existing control please?I am Inheriting from TabControl and I do not want the base New Sub called, is this possible?In other words, I do not want TabPage1 and TabPage2 to be added.A Form has an Activated Sub which runs once a Form is activated.It is a pity that Microsoft have not got such a method in the baseControl Class otherwise I could have used it within a custom TabControl.
Public Class Form1
Private Sub Form1_Activated(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Activated
I have an application going here Form1 has a panel on it named TargetPnl. I need my TargetPnl to display my user control named Vviewer when I click my SearchBtn and also need it to disappear when I click another button.View 1 Replies View Related

I have an aspx page that has two different user controls. I want to find user control A and be able to set properties, etc., from user control B.
I was thinking I could do something like this:
Dim CMFilters As Control = Me.Parent.FindControl("CMFilters")
...but that doesnt work to be able to set properties and call methods. I somehow need to get the user control and and declare it as that user control type.
I have problem in Form controls. I inherit label control in a class Mylabel i use this label on my form not standard label control. now i want change the Font all Mylabel in my form then it not change Font when i use standard label control it's work.

For Each Ctrl as Control In Me.Controls
Ctrl.font= new Font("Arial",10)

I have read and played with code that streams output to a richtextbox but that is runningit from cmd.exe but I run kix32 programs like anything.kix using commmand line kix32 c:anything.kix and it can be run from a *.cmd file as well.
why havent' experts made a toolbox item/control that is say called console? like they seem to have many others dialogbox - browse box etc...? It has been years since VB.net has been out. why why dont they make one??huh? I have looked all over net and it ant no easy job either.
I mean all the code i see makes it very difficult you have to be an expert just to make the coding. Is there some class or something that maybe a beginner/intermediate might be able to tackle..
I just want the command line that is initiated by the kix32 engine to be streamed to my richtextbox in my gui vb.net program

I made a custom control that is a 15x15 grid designed to show a tiled map. Inside I have a class that inherits from pictureBox. The problem comes when I try to place my DLL inside the toolbox. When I click "browse" and select my DLL to import it simply import my class inheriting pictureBox instead of the whole package.
Here is a picture of my files. Grid.vb is the control, clsTile is the pictureBox class and the other one is irrelevant. [URL]

I have the following references in my project:
CrystalDecisions.CrystalReports.Engine, .ReportSource, .Shared, .Web, .Windows.Forms
I also tick crystalReportViewer in .NET Framework components, but the crystalReportViewer control is not get added up in the toolbox.
I made a customized TextBox that I'd like to permanently add to the toolbox. But when I close the project that I created it in, my new control also disappears and I have to copy/paste or import the class-code every time I want to use it. Is there a way to get the control in the toolbox "forever"?I tried to enclose the class in a "Namespace CustomClasses" statement and changed the root namespace in the project properties to "CustomClasses", but nothing of what I tried is permanent. I prefer to store my classes in a "real" root namespace, in the same root as the microsoft and system namespaces.View 4 Replies View Related

I am upgrading user control from vb6 to vb.net.In the vb6 application I am loading 3000 labels using a label control array.In vb.net I am doing same but it's taking too much time to load.In vb6 it's taking 1-2 seconds, but in vb.net it's taking 30-40 seconds for same work. Why does it take too much time in vb.net for same work?Code is given below, here Led is the label control array.

I'm interested in a description of the step-by-step process for creating a custom control and making it available in the toolbox with vb2008. Just for an example, suppose one wanted to have an array of 9 buttons in a 3x3 pattern already labeled 1-9 as a control usable from the toolbox just as a single button or label etc. is, so that one could drag it from the toolbox to the form or a groupbox.View 1 Replies View Related

I am trying to use the Web Browser control in my vb .net user control. I am using VS 2008. Finally, I will be calling my assembly (.dll) from a web page. I wanted to display the usercontrol with the web browser control inside this web page. The problem is I cannot proceed since the Web browser control cannot be called from a partially trusted assembly. Using VS 2008 I have created a strong name for my class, also added the <Assembly: AllowPartiallyTrustedCallers()> to the AssemblyInfo. But still the web browser control cannot be seen in my web page. Do you how I can make my assembly fully trusted so that it can access web browser control? If you have used web browser control, can you confirm if this step is really required?!View 2 Replies View Related

I tried it and get an error but maybe I'm tring the wrong way. Can a usercontrol inherate an application defined class ie.. could you inheritance a classic rect class into a user control to add the hight and width properties to the control without having to do all the coding all over again? Currently I just declair a private instance of the class within the control and then encapsalate. It would be nice if I could just inherit all the functionality of my classes into controls designed to implament the classes.View 1 Replies View Related

I have an asp.net usercontrol which represents a "popup" dialog. Basically, it's a wrapper for the jQuery UI dialog which can be subclassed to easily make dialogs. As part of this control, I need to inject a div into the page the control is used on, either at the very top or very bottom of the form so that when the popup is instantiated, it's parent is changed to this div. This allows "nested" popups without the child popup being trapped inside the parent popup.
The trouble is, I can't find a safe way to inject this div into the page. A usercontrol doesn't have a preinit event, so I can't do it there, and calling Page.Form.Controls.Add(...) in Init, Load or PreRender causes the standard exception "The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases."
I thought I had found a solution by using. ScriptManager.RegisterClientScriptBlock(Page, Me.GetType, UniqueID + "_Dialog_Div", containerDiv, False) which seemed to work well normally, but recently a coworker tried putting an UpdatePanel inside the dialog and now she's getting the error "The script tag registered for type 'ASP.controls_order_viewzips_ascx' and key 'ctl00$ContentBody$OViewZips_Dialog_Div' has invalid characters outside of the script tags: . Only properly formatted script tags can be registered."
How are you supposed to add controls to the pages control collection from inside a user control?
If I need access to the value of a user control's property BEFORE PreRender, would I need to base the custom control off of one of the preexisting data controls (repeater, listview,etc.)?One of my user controls features a gridview control that is configured based on the user control's properties on which it resides. Several of the key properties alter the SQL Statement for the underlying recordsource. I'm now in a situation where the property that sets the WHERE statement for the SQL Statement needs to tied to a value in the user control's parent FormView. Think of the formview as displaying a customer detail record. The user control takes the customer's account number and then displays data from a related table such as Customer Contact Names. Since the gridview is created before the control's prerender event, working within the prerender event doesn't seem efficient.View 1 Replies View Related

The particular control I'm trying to figure out is a UserControl. When I design it as a separate DLL, add it to the Toolbox, then drag it onto the form, it shows up. But when I declare the instance in Form_Load & add it to the Forms Controls, it doesn't show up. (Note that I'm dealing with two different UserControls here as what I don't really want to do is create it as a DLL. It's specific to this project & that's where I want it-in this project. I suppose I could create it as a separate project in this solution, but again-that's not what I want to do. I can add a UserControl to this project, but I can't seem to *use* it. Frustrating.)
Dim X As New Class3
X.Size = New System.Drawing.Size(96, 74)
X.Location = New System.Drawing.Point(5, 5)
Class3 inherits System.Windows.forms.UserControl, and contains a label.OK, found that I can make the UserControl appear by setting the BackColor (X.BackColor=). Doesn't seem like I should need to do that as it's set in Class3, but apparently when I add it to the form it picks up the form's backcolor-which might be the way UserControls work.
But, it still doesn't show the label that's on the UserControl-just a block of color where I placed the UserControl.And now, I might have solved this problem only to raise another. I finally noticed that although Class3 had an InitializeComponent sub it lacked a Sub New-so it never called the InitializeComponent sub.
I added a Sub New that does nothing except call InitializeComponent & now I'm getting the whole thing. I guess now the question is why the Sub New is required for Class3 but not for the DLL? (Or maybe it was created automatically for the DLL but not for Class3? I'll check the hidden code in the DLL project to see if it was created or not.)
