I am trying to add datagridview control in my custom control but i failed.
I started creating new project[windows custom control library], added datagridview control on it and also added a property naming "DGVMain" which refers to datagridview control.
I compiled it.
While testing i find its properties like visible and other working but when i click on columns property it doesn't work. i.e i cannot add/edit columns into the datagridview of my custom control.
Did i miss any steps or do i need to add some more actions?
As you don't have other control within your custom control, maybe an inherited user control would be more appropriate in this case and I'm sure it will also fix your problem.

I used a custom "skin" or w/e you may call it for uniquely designed forms in Visual Studio, to be accurate for VB.NET.
I decided to remove the custom form and the problem is that all controls are now hidden, but they still exist within the project.
Is there any way to make them visible in designer again, so I can add them to my new form.
Check to Location of the missing controls , maybe it's outside bounds.
I have a created a custom user control which consists of 2 controls:-
Textbox
Listbox
The function of this control is to act as a dropdown list. Below is the image of the control:-
Problem
Now the problem i am facing is that if i insert this user control into a container control like a panel then the list gets hidden inside that container control.
and if i just create the user control outside the container control then it would interfere with the Tab Order (focus order) of the form.
Is there any work around where the user control exists in the container control and still shows the complete list without being hidden in the panel?
Edit i wrongly added c# instead of VB.NET
It can be achieved by having the list as ToolStripDropDown. Similar customization have been done in the following discussion,
Show control inside user control outside the boundaries of its parent
Hope this suits you.
I've taken over a project, which contains some UltraWinGrid controls on some of the forms.
On one of the original forms which has been there since before I took on the project, there is a ContextMenuStrip, which has just one ContextMenuToolstripItem on it, captioned 'Default for Column'.
This ContextMenuStrip is hidden by default, however, when the user right-clicks on the UltraGrid, the ContextMenuStripItem is displayed on the grid (rather than at the top of them form where the ContextMenuStrip is).
I'm trying to replicate this behaviour in a new form that I've added myself, however, after adding the ContextMenuToolstripItem in, I cannot get it to display when right-clicking my grid.
I've put a breakpoint on every subroutine in the in the older forms class, and none of them are triggered when right-clicking it.
Additionally I have also searched the class for DefaultForColumnToolstripMenuItem, and the only place it appears is in the Click event of the ContextMenuToolStripItem itself.
So, how else is it possible to show it when right-clicking the grid? I've copy and pasted the ContextMenuStrip from the old form onto the new form and still nothing occurred.
I'm assuming it's in a property somewhere that I'm missing?
Check for a ContextMenuStrip property on the UltraWinGrid. You can set it in the designer and your context menu will appear on right click without having to deal with the MouseClick handler, checking the mousebutton used, etc.
For a custom control I'm making, the datagridview is pretty much only going to be a customized version of the original. However, so that other controls I have made can interact with it, I have made it inherit my MetroControl class.
Since I cannot add multiple "Inherits", I have placed a DataGridView and docked it inside the control. From here I can then influence and theme it. Most of the properties are handled by my theming (such as the "RowHeadersStyle" etc..
I need to push forward the "Columns" property of the DataGridView so that the user can interact with the same column setup screen that they would as if they were using the normal DataGridView. Is there any way I can simply forward this property (as it would make it much easier for both me and the user)?
Yes, you can add a property on your UserControl that just returns the Columns property on the DataGridView (Assuming that your DataGridView is stored in field named dataGridView):
public DataGridViewColumnCollection Columns {
get { return dataGridView.Columns; }
}
That's it
When answering another question I started to wonder how I could Add new properties to all controls in a form just like the ToolTip-control does.
For example I could use that to Add a "IsDirty"-flag to all textboxes just by adding the component to the form and it would handle this for every textbox.
When adding the tooltip-control to the form all controls magically gets a new property "Tooltip on tooltip1" that can be set both programatically and in design view.
I want to be able to do my own enhancer like that.
It's an Extender Provider.
