I'm trying to do a scheduler for a lesson schedule. Which control should I use and how to do?
Here you find an image of what I'm trying.
You should create a UserControl based on the "DatePicker" control.
And then redefine the control template, using a UniformGrid.
There is no simple and quick way to do that yourself. Either you recreate a custom control based on a DatePicker, or you try to find a library of controls already doing what you are trying to.
I believe a few controls already exists to do that, but I don't have names to throw in.

We're developing a custom control (to make our lives easier), which included a customs (external) grid control and some default buttons and text. The grid control has the option to add columns by clicking the small arrow on the top right of the grid in designer, like shown in the picture.
We want to keep this option when putting our new custom control on a (win)form. Is there any way we can achieve this?
I've already looked into the 'verbs' and I can add my own custom verbs to the new control, but I'm not sure the arrow is a verb (as it does not show the option on the bottom of the properties). I also haven't been able to find how to use the verbs from the grid control.
Thank you very much!
I've found the solution to my problem.
I thought the way to add columns was a custom control when in reality, it was a default CollectionEditor. This, in combination with Smart Tag, solved my problem.
I want to add control to user GUI that would represent excel like table but I cannot find additional control that would do that. Control like that would be used for easier data entry.
I believe that VBA has control like that and I am missing something obvious.
Does anyone know where to activate control like that?
If you have VB6 installed then, this should work:
Microsoft Flex Grid Control
However, if you do not have (vb6) then, another option is to create one yourself by dynamically adding controls to your UserForm (such as a textbox) and then tracking those object. It would take some work, but it would be an option.
So I've made the following control in Design Mode then added the control to a new page Custom in my toolbox.
Now, what would I use for the progID parameter in Controls.Add()? How do I look up this value? Controls.Add("Forms.Frame.1") adds a regular frame, not the desired custom control.
As far as I am aware, you do not generate a new progID with a custom control. Per the MSDN documentation for custom/modified controls:
Note: When you drag a control onto the Control Toolbox, you only transfer the advanced property values.
So only the properties are transferred; the actual control is still of the same type/s as the one you created it from. Further, it looks like this progID is "a unique system-wide string that the Windows operating system can use to identify your control's type." So unless you are up to coding your own control, it looks as though you're just passing properties to the custom toolbox controls you create there.
You'll have to just replicate the custom control each time you want to add it. Just create a sub with all the correct properties and call it. Not what you were looking for, but it'll get the job done.
To illustrate what I'm asking, let's say I have a custom TextBox that has 2 modes. Mode 1 only allows numbers, and mode 2 only allows dates in a particular format.
Using a class module I can create this custom TextBox, and I can use a loop when the userform initialises to set which TextBoxes are custom.
What I'd like to happen is have the custom TextBox, or what ever custom control I want, show up in the toolbox. And I also want its custom properties, if they exist, to show up in the property window.
So far, I've been unable to find a way to do this. In fact, I've been unable to find out if it's even possible. It seems, to me anyway, that it's something that should be possible, but maybe I'm barking up the wrong tree. If it's possible I'd really appreciate being pointed to a resource.
How do you create your own custom component for vb.net 2008? I want it to simply output to a .dll, not a whole winforms app.
So, here is what I have done so far:
Made a class library project
Added a custom control object
Confused myself badly
Googled it, to no avail
How can I control the component? For example, I want my component to not have a visible design view, I want it to stay below like the stopwatch component and the notifyicon component and such, it is not something to be designed. Then, how do I edit the possible properties a user can control, and make them effect the end result? What do I place the code which powers the component on? The class library file, or something else?
Thanks for your help! I have a whole set of components I am going to create, this will get me going much faster than trial and error.
I think you may want to check some walkthrough on how to create components. Such as this one: Walkthrough: Authoring a Component with Visual Basic. Once you are done with that one, there are more walkthroughs on various related topics, such as how to use design-time support, implementing designers and so on.
OK... This is a really abbreviated example. You should start by basing yous off of an existing .net component.
Public Class MyControl
Inherits DataGridView
'...add your properties/functionality...'
End Class
Then compile the DLL, and add it as a reference to whatever project you are working on. Once added, you can add the controls in the DLL into your toolbox.
This has more instructions on how to modify a UserControl (slightly different from the one above, but it explains well. This is a general explanation.
#comments -
Yes, there, are things that will do what you want. Start with a class that inherits Form instead of DataGridView in the example I gave you, and the changes described in the links provided.
"Your properties and functionality" is whatever you want to do that the base control does not do.
