What I am trying to do is fill the contents of the datagridview with the cell contents. There are two ways to do this.
1) Either set the DGV width to the cell contents width, or
2) Autoadjust the width of the cells to the width of the DGV.
how to implement either of these two approaches?

In VB.NET for the combo box, I have set the autocomplete mode to "SuggestAppend" and autocomplete source to "ListItems". Its working as expected. But the width of the autosuggest dropdown box is not same as that of combo box and so it looks weird.I tried changing the value dropdown width property but it changes the value of normal dropdown box (seen after clicking down arrow on combobox), and not the autosuggest dropdown box.So what code or property needs to be set to make autosuggest dropdown box the same width as that of combobox width?
View 1 Repliesbeen trying to find examples of how to go about auto sizing the controls i have within a grid control if the users screen is larger than the default size.Currently i am unable to resize the controls when i enlarge the form. Is there any code currently that can find all controls inside the grid and resize them on the fly when the form is resized?My current code is:
<Window x:Class="Window1"

I have a custom datagridview control. I am loading data into it row by row. The control does not resize its cell width to its content. It only does so if I set autosize column property to Fill or AllCells. The problem is I can not use autosize because its killing my performance as I am loading large amount of data into the grid.
The cell does not display the contents completely, it just clips it. e.g for "sampletext" it would display "Samplet..." .
I want the cell to be resized according to the cell that contains the longest string value.

I have a drawing program written in VB6 that is capable of printing very thin lines to a laser printer. In VB .net, even though the pen width is set to 1, the thinnest lines are way too "thick". The equivalent line width in VB .net using a pen width of 1 is about the same as the DrawWidth = 4 in VB6. So, my question is, how can I print very thin lines to a laser printer in VB .net?

I want to be able to hide the left hand side of the screen and right hand side of the screen at the beginning of the program.
Then when the user presses create new button the left hand side of the screen becomes available so they can create the new item. Then when they press save it comes back to the middle datagrid only.
Then I want to add an event when the double click on the datagrid row (data is programmed in to the datagrid in the code) the right hand side of the screen becomes visible then when the button allocate is pressed the right hand side disappears again just leaving the datagrid.

I am using this code which I am checking with the form width size that if they are greater than 672, then do something....

If Me.Size.Width >= 672 Then
MessageBox.Show("the form size is greater than 672")
Else

When the width size is no greater than 672, the messagebox will display that it says "the form size is greater than 672" which it sound didn't looks right for me. What I am trying to do is to check the width size that if they are greater than 672 then display the messagebox that says "the form size is greater than 672", otherwise if the width size is no greater than 672 which is equal, then display the messagebox that says "the form size is no greater than 672".

View 3 RepliesI have a comboboxcolumn in a DataGridView. I have loaded int with string data that appears in the dropdown box. I have added an event to it for an SelectedIndexChanged. What I am trying to do is autosize the width of the cell in the column based on the string chosen in the drop-down box within this SelectedIndexChanged event. This seems to work but it does not work off the initial selection change. When I select the desired string in the dropdown box the width of the cell does not autosize. I am not sure why.
I was trying to get around this by wrapping an IF stmt around the autosize logic by saying if cell value = "" then cell.width = Max Width of all loaded strings/ However, I can't figure out how to access the string array loaded into the dropdown list

View 4 RepliesI have a databound DataGridView, and I'd like to keep one column in front, with a slightly smaller width than the default. The grid's AutoSizeColumnsMode property is set to Fill so that the columns fill out the entire grid. This makes the first column equally large as all others, which is why I need to set its width manually. The smaller column is the first one with the checkboxes. I have two grids that I need to do this with, and for some reason it works just fine with the first grid, but gives a null reference error on the second grid...
Here's the code for the first grid (working fine):
vb.net
Public Sub UpdateTodoGrid()
' Load todo items
todoGrid.DataSource = _TodoManager.LoadAll()
' Set backcolor
For Each row As DataGridViewRow In todoGrid.Rows
[Code] .....
As you can see, the code is exactly the same (except for not setting the BackColor of each row and not using the ReadOnly property*). When I run this code, it gives me a null reference error ("Object reference not set to an instance of an object.") on the line where I set the column's Width. Obviously 'col' is not Nothing (otherwise it would have errored before that line), and there's nothing else there that could be Nothing... I assume that something happens internally in the grid when you set the width of a column, and that there is a null reference there, but obviously I have no control over that.
The grid's are absolutely the same, as the second grid is just a 'copy' (meaning I copy/pasted it in the designer) of the first. So all their properties are equal. I thought maybe the ReadOnly properties were the problem, but I tried putting them in in the same way and the issue did not go away... The first grid is not ReadOnly (because the checkboxes need to be editable), but all rows except the first are, while the second grid is completely ReadOnly.
I have a form with a text box in a toolstrip. I would like to make the width of the textbox relative to the form size when the form is resized. The following code works fine except when you click the restore button from a maximized state.
