I have added an labels on the PictureBox element, due to a fact that PictureBox is dynamically resized while loading (not very important in this case what does it load)... the problem is that the labels are under the picturebox elements, and arent visible when picturebox is over them.
Is there any solution to set the labels display order to the top available?
You can use the BringToFront method.
label1.BringToFront()

I have 2 panels on windows form and both occupied the equal portion on form (i.e. 50%- 50%). Once i run the application, I want to resize the panel size by dragging form with mouse (i.e. 25%-75%). The portion given is not fixed it can be in any size. I just want to resize the panel by dragging/streching mouse.
Please help to resolve the issue.
Thanks,

I think you want to use a SplitContainer control on your form. Put the Panel controls into the two different containers of the SplitContainer, and set their Dock property to Fill. You can set the SplitContainer to Dock.Fill too or set the Anchor properties such that the SplitContainer stretches along with the form.
I have a project where I want to place a png on the form like a "Rubber Stamp". I have the transparent *.png but I need it to be transparent on TOP of all the textboxes, labels, etc. Every time that I use a label or picturebox to hold the image, you still see the form background. It's not being brought transparent on top.
Any assistance is appreciated.
Assuming I understood your question right, let's say you have a PictureBox called PictureBox1, and a Label called Label1, and you've placed PictureBox1 in front of Label1, and the PictureBox has a transparent background. In the form's load event:
PictureBox1.Parent = Label1
If this doesn't work, try adding
PictureBox1.BringToFront()
I have a form with a floating gridview that must appear when filling a textbox or clicking on a button. If item selected or mouse leaving grid, grid becomes invisible so user can see rest of the form. Grid data most cases exceed maximum vertical size, so a vertical scrollbar is needed. My problem is that when mousing to vertical scrollbar triggers MouseLeave event, so grid becomes invisible.
This time I think it's not a code matter, so is there some property to change to make the program identify vscrollbar as part of the GridView? Or else is there some code solution to ignore MouseLeave event when mousing to scrollbar?
Here is my event code, pretty simple:
Private Sub GridCliente_MouseLeave(sender As Object, e As System.EventArgs) Handles GridCliente.MouseLeave
GridCliente.Visible = False
End Sub
Also, I'm using Component One C1TrueDBGrid instead of standard gridview. It may be important.
I found a solution to my problem by adding the GridView to a panel and changing the MouseLeaveevent to the panel. For this to work, the panel must exceed the GridView size at least one pixel each side, since MouseLeave will not trigger if GridView is the same size of the panel (you must mouse over the panel and not any other component inside it to have vb.net consider mouse inside panel). Maybe it's not the best solution but it works for me.
Good afternoon.
I'm having a problem resizing a listview in a form.
In the normal position the listview is placed correctly as you can see in the image.
When i maximize the form, i get a huge space between the top controls and the listview.
How can i solve this situation, so the listview can expand and stay near the other controls?
Thank you.
Set the ListView's Anchor property to all four sides.
Sometimes, I have a picturebox lets say 100x100. But the image it will display is actually 100x400.
I don't want to increase the size of the picturebox itself. Instead, I would like to create a vertical scrollbar (or horizontal if needed).
I could not find a scrollbar in the toolbox, so I guess I have to code it. But, how?
And I still wonder if I didn't make a mistake and didn't see the scrollbar in the toolbox. My apologies then :(
I suppose you could add separate scrollbar controls and sync their Scroll events up with the offset at which the picture in the PictureBox is drawn, but that sounds like actual work. There's a better way.
Add a Panel control to your form, and set its AutoScroll property to "True". This will cause the control to automatically show scrollbars when it contains content that lies outside of its currently visible bounds. The .NET Framework will take care of everything for you under the covers, without you having to write a single line of code.
Drag and drop your PictureBox control inside of the Panel control that you just added. The Panel control will then detect that one of its child controls is larger than its visible area and show scrollbars, thanks to the AutoScroll property. When the user moves the scrollbars, the portion of the image in your PictureBox that is visible will be automatically adjusted. Magic.
(The reason you have to use a Panel control as a container is because PictureBox does not inherit directly from the ScrollableControl base class, which is what provides the AutoScroll property.)
I tried this and it worked well. But I noted that if the picturebox is docked in the panel, the picturebox is automatically set to the size of the parent panel, and can't be set larger (at least not in any way I could find). This defeats the purpose of the technique. So -- put the picturebox on the panel, but don't dock it, and it will work perfectly.
There are no automatic scroll bars on a picture box, but you can add the VScrollBar (and HScrollBar) control to the form and handle the image scrolling manually by redrawing it at a different offset each time the Scroll event is fired.
