I have a DataGridView on a Windows Form that can have up to 25 columns and up to many thousands of rows. There are no defined columns in the DGV, these are dynamically generated in the code. No columns are frozen. The DGV works as expected in the version I inherited. Then I got my hands on it…
I am adding a toolbar to the form. The issue I am facing is that when I lower the top of the DGV to fit just below the toolbar and ensure the DGV fits on the form, I lose my horizontal scroll bar. I can scroll the thumb off the form, so it is no longer visible. My Document Count field shows as expected in the image below.
DGV no horizontal bar and thumb scrolled off form
Some potentially related field values from DGV Properties:
AutoSizeColumnsMode = None
AutoSizeRowsMode = None
Dock = None
ScrollBars = Both
Any input would be much appreciated.
Added a Screen Shot to help clarify the issue.
Design View of the form
Solved! Thanks #Luke #LarsTech for suggestions. Not sure why but recreating it solved the horizontal scroll bar issue. I deleted my grid and recreated it in the Designer just like the previous one. This time I used Dock Right instead of None or Fill. I did use BringToFront also, because SendToBack shrunk my toolbar to half the size. I lost my blank area on the right of the grid, but i can live with that.
Thank you so much for the help!

So I'm having troubles making my FlowLayoutPanel work the way I want.
When adding multiple controls to it so that vertical scroll appears and when scrolled to bottom I don't want controls to be touching the bottom border of FlowLayoutPanel.
Padding works properly for all but the bottom side, controls are properly spaced away from the edges of the FlowLayoutPanel, I don't know why bottom is special.
I need a solution that does not include adding invisible/transparent controls to it.
The closest I got to what I want was lowering the clientsize by some amount, but then in that area control doesn't repaint so it shows parts of added controls forever.
Kind of fixed with with larger margins on child controls, so I'm closing this.
I am creating a UWP app and I am using the VariableSizedWrapGrid control. I am binding the Width of the a ComboBox in the grid to it the ComboBox width resizes based on the entries in the list. ( I am using a simple property exposed through my view model.) When I had the items in a StackPanel with a Horizontal orientation it worked fine. See picture below
The challenge of course is that on a smaller screen I need the fields to wrap around. So I switched the StackPanel to a VariableSizedWrapGrid. However, when I do that, the Grid does not seem to be handling the resizing of the ComboBox correctly as I get what is shown below. (See the ComboBox is now cut off
Any suggestions on how to resolve this would be greatly appreciated.
You are using the wrong Panel for the job. The one you're looking for is a WrapPanel (which doesn't exist actually though), but there are some implementations available, eg.: http://codepaste.net/8gr5go
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.
EDITED:
I think we can just draw an image that resemble the grid using this article : drawing in a datagridview Currently creating a way to make the image drawn in tile mode. :)
Each time I develop a datacentric application using VB.NET regardless of how much the data displayed in the datagrid, I always want the grid to display full row of empty data, not just blank panel.
Can we achieve this using VB.NET design time property?
And also, we must not trigger the display of vertical scrollbar this way.. :)
Thanks
You might try doing a screen capture of the dgv when it is full of blank lines and use that as your background. However, you'll have a problem with the vertical lines if they resize the columns. In your picture you don't have any vertical lines so if you don't need them then just erase them and your problem is solved.
There's also the option of using the Virtual Mode. When you set that property to true then you can set the number of visible rows, but you are responsible for telling the dgv what each individual cell is supposed to contain: http://msdn.microsoft.com/en-us/library/2b177d6d.aspx
Or you can just add extra blank rows to whatever datasource you are setting your DGV to.
Use the ScrollBars property to turn the vertical scroll bar off.
I have one gridview which was in a panel and I set panel's Scrollbars property as vertical and height 200px. Gridview has number of rows (say 1000). If i scroll down and selected a 900th row,scroll bar will move to top.I want to focus on that row after selection(ie.scroll bar will be on the same position when we selected). Is there anyone to help me?
your gridview can have scrollbars too I think.
Otherwise try using datagridview. they are slightly different with properties.
If that doesnt work check the properties of your gridview.
Are you allowed to edit or select anything?
I think if you answer those questions the solution will show itself.
Hope this helped.
