View 2 Repliesduring design time i cannot figure out how to resize the datagridview columns in vb.net!
View 2 RepliesI'm trying to allow users to resize columns of my datagridview, but it's not working. I have this line:
DataGridView1.AllowUserToResizeColumns = True
I want users to be able to resize columns the same way they would if in excel.
So i have this code that adds two Columns to the form at start up.But my question is that how can i make the Columns to resize with the form movement?
ListView1.Columns.Add("The Path Of The File", 800, HorizontalAlignment.Left)
ListView1.Columns.Add("Size", 80, HorizontalAlignment.Left)
Is it possible to have the columns in a listview resize when the listview resizes for the form. Im using VB 2008 express edt.
View 1 RepliesI got a very simple question regarding resizing listview columns. I have a form with a listview anchored to it (top, bottom, left, right). The form is resizable and the user will be able to resize the listview columns manually. However, I need the listview to resize its columns automatically when the form is resized (especially when its maximized).
But, I don't want all the columns to resize, only the ones I choose. For example, the listview will have 6 columns in total (0-5). When the user resizes or maximizes the window, I need only columns 2 and 4 (or columns 3 and 5 or columns 1 and 5) to resize. Now, I have come up with two pieces of code as listed below.
Code Part A: The following code only resizes one column. When the form is maximized, only the column ID provided will resize and fill the rest of the control. It works perfectly but I need to be able to resize multiple columns (as explained above):
Public Sub lvResizeSingleCol(ByVal resizeColumn As Integer, ByVal listViewName As ListView)
Dim w As Integer = 0
For column As Integer = 0 To listViewName.Columns.Count - 1
If column <> resizeColumn Then
w += listViewName.Columns(column).Width

How do I sort a DGV by 2 columns? The DGV is not bound.
View 4 Replieswhat's the best way to add some space between some columns, just to aid the user to read/understand the data (i have more than 50 columns).In this particular case i'm using a data bound dgv and one approach that i'm using currently, it's in the SQL statement add a new column named SPACE1, SPACE2, etc...Something like:
SQL
SELECT col1,col2,NULL AS SPACE1,col3,NULL AS SPACE2...
I know that i can add columns at runtime, and handle the cell paint event to change the left and rigt margins... But i don't know what option should i use, does anyone know a better way or in the above three it's the best one?
So i have a datagridview with two combos, when the form it's created i fill the first one with all the MainValues, and the second one with all possible values for the MainValues (called SecondValues) (1..N).Now my issue, when the user selects one value from the first combo i want to fill the second combo with all values related to the selected MainValue, i can do this for example by filling the datatable again with a parameter that filters the data, but if the previous rows have different main values, the dgv throws errors because it doesn't find the binded ones in the new filtered datatable.
How can i handle this? One datatable for each line?! Other thing, i'm using the SelectionChangeCommited event for handling the values change (in theEditingControlShowing), but if the user uses the keyboard to select the values the event doesn't behave in the same way or the way that i need. The values in the combo are numeric values (1001,1020,2010,3010), when the user select one of the values, i need to fill another cell in the same row with the number selected plus some string, example combo:1001 cell:1001XPTO. So if the user presses 1 in the keyboard the combobox selects the 1001 and fills the cell with 1001XPTO, but if i keep pressing the keyboard to select the 1020, by pressing 0 and 2, i get the 1020 selected in the combo, but the cell remains with the 1001XPTO.

I am trying to figure the best way to programmatically re-size table column headers in ReportViewer.Basically, my current resolution is the following: ColumnWidth = Header Caption_CharacterCount * 0.32...Where 0.32 is an estimated width of a typical character using my current font size.The issue is that the width leaves a lot of whitespace for longer captions.The more characters a caption has, the more whitespace I end up with.The issue with estimating this way is that not all characters are the same width. A good example would the the "I" character, which takes up less screen width than the rest of the alphabet.[code]

I have code to add the columns and populate the first combobox, but I can't figure out how to do the second one since it can (and usually will) have a different list for each row AND the list must change when the selection in the first is changed.

Is there a way to programmatically send information from a text box into specific columns in a DataGridView? I tried
vb.net
Column1.Text = TextBox1.Text
and it obviously does not work.
I want to be able to have a dozen or so text boxes be emptied into separate columns in a row of a datagridview. This way the text boxes can be cleared and have new values entered then save the new values as a second row in the datagridview. This is so my VB gui which which runs everything through an old cmd line program, can do batches instead of one run at a time.
The problem is I have absolutely no idea how datagridview works. I've tried searching google and only found some vague things and stuff about databases. I also tried the MSDN library and that was of no help either, couldn't find anything on simply adding stuff and if I had it'd probably be to complicated to be of use to me.
I want all the contents both in columns and rows to auto resize its length depending on the length of text that is to appear in the cell...but it seems I cant get the idea on how to properly use the auto size method.

View 5 RepliesI uses datagridview for show query results from database which may have 0 to x number of rows. So I made calculation to calculate size of underlaying form and my datagridview dependable on number of matched rows. Underlying form is transparent and all of that looks like user control what appears and works just fine. But here is one issue: Every time datagrid have to grow, black square in that area is showed before datagrid is filled, what is not nice and surely unwanted. Did datagridview have some mechanism to freeze it and show data when populating is finished?
