To grant this application the required permission,<br/>
contact your system administrator, or use the Microsoft .NET Framework Configuration tool.<br/>

i'm having one user control in asp.net ,i just want to add the user control multiple times in a single web page in runtime in a separate table. How to do this?
View 3 RepliesI'm coding an application that will work with many arrays of data. To make the code easier I want to make a user control (called Multiselect) that will include a textbox and a treeview. The textbox will be alway visible and treeview will appear when needed.The user will put a string in the textbox and the MultiSelect will search all of the stored data in a array that match the searched string. When done, the TreeView will appear and show the found items. User will have an opportunity to choose the right items through checkboxes.
What I can't do is the TreeView. I want it to act like the autocomplete in Visual Studio editor - for example you are in a class and type "me." and Visual Studio offers you all methods possible in a window. This windows doesnt get focus, but if on the top of the main form so the found items are visible over the text.
I am currently trying to create a generic navigation control with a similar style to the outlook navigation bar. I have figured out how I would be able to dynamically create the bottom part where you select the menu option, but I'm struggling to figure out how I would be able to create the top part, which can contain any user control that the developer would want.So basically what I'm trying to figure out is, is there a way to allow for a developer to add controls to a specific area of your user control?
If there is a way of achieving that then if anyone knows how to do this;In ASP.Net you have the login controls and with one of them, you are able to have different views depending on whether the user who is viewing the web page is logged in or not. Is there a way of achieving this in VB.Net for a user control that could be set up so that I could have the developer able to switch the view in the designer to show them the view for when a specific navigation option has been selected.
I have followed the directions from this web site and the control works on a new form. But I have now written my own User Control. It compiles, I have changed Active Config within the Solution Properties to Release | Any CPU and built the Solution. But I can not find the .dll within the .NET framework Components after selecting Choose Toolbox Items from the Tools menu.
View 2 RepliesI have a bit of a problem creating a user control at the moment. I'm creating it within my current project via the 'Project> Add User Control' menu item. The problem is that when I create the control, run a build and add it to my form the controls within the custom user control are about one and a half times the size they should be.

creating a user control object in runtime using createobject function or whatever better function in vb.net.

Dim b As New Security.Sec_Role
b.Name = "Sec_Role"
b.visible = true

I want to show a Listbox below the cell of datagridview, for that i inherited a

I use this code
Public Class DataGridViewTLBoxColumn

View 4 RepliesIn my project i added a User Control so that i can reuse in different Windows forms.I designed and coded the UserControl1 according to my need and now i want to use it in Form2 but i cant understand how to do it?
View 2 RepliesI have created a User Control in VB 2005 that adds other controls dynamically. This is a fairly simple test project, with checkboxes added to the control at run-time. Here's the user control:
Public
Class UserControl1
Public x
[Code]......
Then I built the test control and tried to added it to the Toolbox. When I did this--i.e., browsed to the dll and double-clicked it, I got the errror message:
"There are no components in ... that can be placed in the toolbox."
Is it even possible to add a User Control to the Toolbox without compile-time components?
I need to upgrade my application to a modern style interface component like Dotnetbar or Krypton,these doesn't provide a equivalent control for bindingnavigator so I have to create it with some buttons and textbox.I use bindingnavigator only for navigation as in the image
It is possible to create a user control (with 4 buttons and a textbox) that inherit bindingnavigator and to have new style buttons ?
I figured it out. Check out the finished control [URL]..I'm trying to make myself a simple 'star rating' control.
It would have the properties:
StarCount (number of stars)
StarValue (number of stars highlighted)
I want to draw the stars using GDI+, have them highlight on mouse over, and change the StarValue when clicked.I have an idea on how to do this from experience with working with forms, but I'm having some difficulties with the Control development part. I couldn't find any tutorials which didn't inherit a control (such as a checkbox or button), and I have no idea how to make my control editable in the designer.
I think what I need to do is create StarCount as a property like this:
[Code]...
I also want to execute my drawing code at design time, so I can see the stars while laying out a form. as a side note to that, I don't know how to change the size of the control at run or design time, nor how to disable the user from changing it at design time.as a side note - I know that there are a few star rate controls already floating around the internet, but I do not like the quality of them (or at least the one's I've seen), they felt very windows 98. I'm trying to make something that will fit well into windows 7 (plus I want to implement custom images, but that can wait until I get it working)
I believe that this is in the correct forum due to it being about creating an interface item, but if I am wrong then let me know and I'll try and bring this thread to the attention of the mods to be moved to a more appropriate forum. I am currently trying to create a generic navigation control with a similar style to the outlook navigation bar. I have figured out how I would be able to dynamically create the bottom part where you select the menu option, but I'm struggling to figure out how I would be able to create the top part, which can contain any user control that the developer would want.

The one thing that I have thought of that could possibly cause a problem is having the capability of knowing when one of the user controls has been clicked, while I haven't figured this out exactly, I believe I should be able to achieve this by having an event for the navigation user control that provides the developer a reference to the control.
While I would hope that I have explained what I'm thinking well, its before my first coffee of the morning so I might have missed out some detail which would help someone to help me if I have then please let me know and I'll provide any details required.Also if what I'm envisioning is Pie in the sky, then let me know and I'll just have to make a base which I would just have to make a more bespoke system.

View 2 RepliesI 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:

...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.
In a user control I have the code shown below.
I now realize that it is incorrect because the container's InitializeComponent property initializations have not run yet and they must be run prior to Refresh being called.

I am trying to build a tournament bracket application. In order to build the application efficiently I would like to make a user control "GameControl" that represents a game and give it attributes that represent the names of the competitors "TeamNameA" and "TeamNameB" ,an attribute "Winner" to represent which team should move on, and an attribute "NextRoundGame" that assigns another instance of the user control so that it can assign the "winner" to one of the "TeamName" attributes of the next round in the competition. If the controls were native to VB I feel like I could do it easily (I have only spent about 30 hours self teaching/tutorial following) but I can't seem to find out how to pass values to custom attributes of custom user controls through code.
