DGV CheckBox - Recognise Which Check Boxes Are True And Update Automatically When The Information Is Opened From A Text File?
May 8, 2012I have code which saves DGV contents including check box columns as a comma separated text file. I also have correct code which will take the text file and re-insert it into the DGV at a later time. This all works.When I'm working on the DGV, I have this
Private Sub DataGridView1_CellValueChanged(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellValueChanged
If DataGridView1.Columns(e.ColumnIndex).Name = "Column12" Then[code]....
So that when the check box is true, columns 1 and 3 turn different colours, and when false, go to a yellow colour.However, when I "re-insert" my DGV info from my text file, the check boxes come back correctly - as true and false on the right rows - but columns 1 and 3 don't change colour. I've tried a "DataGridView1.Refresh" option but not getting it to work.The DGV is unbound. I need it to recognise which check boxes are true and update automatically when the information is opened from a text file.

Password Loop Textbox - Code Works To Read The Entry Data And To Recognise The Correct Data, And The Incorrect
Apr 16, 2012CODE:
That code works to read the entry data and to recognise the correct data, and the incorrect. However, even if entry is correct, the error msgbox will appear (x times of how many records there are in file), despite being navigated to the menu. Anyway that the Else isn't triggered when data is correct. Also for it to appear just one instead of (x times of how many records there are in file.)
.net - RaiseEvent From A UserControl That's Placed On A UserControl That's On A Form?
Jul 11, 2011I 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.

Setting Usercontrol Properties Within A Usercontrol
Mar 22, 2012I 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?
Code in UserControl:
Public Property DBItems() As List(Of String)
Get
Return DBItems

VS 2010 Load Data Into UserControl In UserControl.Load?
Sep 25, 2011I 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.

Asp.net - UserControl And Inner Properties?
Jul 30, 2010I 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:
AggregateFeeds.ascx.vb
Imports Microsoft.VisualBasic
<ParseChildren(True)>
<PersistChildren(False)>
Public Class AggregateFeeds
[Code]...
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?

Now the project itself was built in C #, but the interesting part of me is "Toolbar.cs".
There is a way to replace the "Toolbar.cs" from C#, to VB? Or i must convert all the project? (Unfortunately, I do not know how)
I just want to build the part that I need(UserControl - "Toolbar.cs") in VB, and the rest can stay in C #, it does not matter to me.

View 2 RepliesHow To Use .net Usercontrol From A 64 Bit Library
Jun 3, 2010I am running through an issue for which I am unable to find a solution.My goal is to:1- compile a x64 .NET library (vb) which has a simple User Control 2- Use this dll in a .NET WinForm application targeted to x64 CPU ONLY.
I have been able to do the first step, but now I am unable to add the library into the VisualStudio Toolbox. With our previous x86 version we had just to right click to VS toolbox, click on "Choose items...", then brows to the needed x86 assembly. If we do the same selecting a x64 lib (of course I am running vs on a 64 bit OS), we get the following message "[DLL PATH] is not a Microsoft .NET module."
How To Use Usercontrol On A C# Page
May 26, 2010I've created a usercontrol in VB that handles paging more efficiently than the DataPager (at least for very large datasets). I'd like to use it in a C# project, but I've been having trouble getting it to work.I've tried simply adding PagingControl.ascx to the C# project, but when I do that the markup and VB code behind don't seem to see each other. --Is this a namespace issue?I've tried adding the PagingControl.ascx to its own VB project, then adding that project to the C# project's solution, as well as a reference. --That almost works. I can register the PagingControl usercontrol in the markup. I can access the usercontrol's properties in the code behind, but any property that involves the UI of the usercontrol fails.
Its seems as if the usercontrol's form hasn't had a chance to load by the time the C# page's Page_Load event handler fires. --Maybe this is an "order of operations" problem? At what point in the C# page's lifetime should a usercontrol's form be loaded?

.net - Mousewheel Scroll An Usercontrol?
Mar 4, 2009I have a usercontrol I created. I added a panel and a vertical scrollbar to the right of it. I'd like to be able to scroll it with the mousewheel. The problem is there doesn't seem to be any events that fire on mousewheel. If I take the panel off then the usercontrol has focus and it will fire on mousewheel in the form. But with the panel on it doesn't seem to fire the mousewheel event of the panel, or the usercontrol within the control or even on the form. The best solution would be to have an event fire in the usercontrol but I'd even accept an event on the form and feed it back into the usercontrol.
I'm using vb.net and vs2005 if it matters.
