VS 2005 Resizeing The DataGridView Cells?
Jul 23, 2009
I created a DataGridView and entered some data in it,at runtime it looks like this:Attachment 72177Here the 3rd row name column cell is a bit short according to the name size....so i want to increase the cell size at runtime such that the user can see the full name.....Again the roll and age cells are a bit short.....so i want to decrease them as well..
I tried this with the AutoSizeColumnsMode and the AutoSizeRowssMode but in vain...How to do this?

I'm working with datagridview.I found an example on the web about creating a datagridview: firs I make my array containing data, then I make a datatable from array, then I make datagridview from datatable.I don't know if it's the correct way but it seems work.In a column I make random numbers for test: for example I have on column "Time" these values: 1155, 1725, 584, 996, 1352.Then I try to sort with code when I press pushbutton: it doesn't work because I have the values:1155, 1352, 1725, 1758 (until now it seems to work correctly), but then I have 584 and 996 values: wrong!Ok, let's try with the manual sorting: same result.I filled cells with "integer" values, let's try using strings, then I used "value.tostring" same result.I also tryed to fill strings with blankspaces to obtain same length, but nothing changed. "1155", "1352", "1725", "1758", " 584", " 996".Then I tryed to fill with "0" values:"1155", "1352", "1725", "1758", "0584", "0996".The same.How can I fill cells values?

i wanna compare my cells in datagridview. I have a datagridview with n columns and n rows. I have my datagridview row value as Time . I need to compare all the row cell values with one particular time.
Here you go with an example.
if my dgv is filled with time values such as 3:42:10 AM 4:43:17 PM etc..I need to compare all the cell values to 5:00:00 PM. greater than condition. I need to highlight only the values which are greater than 5:00:00 PM but less than 3:30:00 AM.

I'm current in college and working on some computing coursework and putting the finishing touches on it when i stumbled across a bit of a problem.I'm trying to compare two cells in a database and i use datagridview to display the database in my form. The database is created by sql commands within my actual program if that makes any difference. What i have created for my coursework is a program that manages the stock and such for a small music shop and in the stock table im trying to compare values in two different collumns, but in the same rows. I need it to display a message box in the event that the value in the one cell is less than the other, which is basically checking if the stock for a certain CD has fallen below the reorder level.

Is the following grid layout possible with DataGridView in VB.net? Kind of similar to html table layout. I'm adding data cell by cell. However I'm not sure on how to get the layout for Group A & Group B Cells.

I have a Windows Form VS2010 .NET 4 project with a standard DataGridView bound to a datasource on a form.
The grid has a text column that I want to be a point and edit at the character clicked to. Like normal textbox/editors when you click on the character you want to adjust. If possible I would also like to use the UP/DOWN keys to move between rows but would like the cursor to move to the same character position obviously in the same column without selecting the entire text.
I have tried a few things:
DataGridView1.ClearSelection()
DataGridView1.BeginEdit(False)
The BeginEdit just puts the cursor at the end of the text, which means another click to point to the character position for editing.
I know a Commercial grid like DevExpress defaults to editing in which you can click to the correct character position with one click but obviously costs money.
I have tried in the DataGridView1_EditingControlShowing event
If TypeOf e.Control Is System.Windows.Forms.DataGridViewTextBoxEditingControl Then
Dim tb As TextBox = e.Control
tb.SelectionStart = 5
[Code]....
I am just trying to remove the two or three clicks to get to the character position that needs adjustment.

I have a DataGridView with cells from a database file that contains data. Basically, I want to get the text from the selected cells in the DataGridView and display it in a textbox at the click of the button. The code for the button click event is:
Private Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim SelectedThings As String = DataGridView1.SelectedCells.ToString
TextBox1.Text = SelectedThings
End Sub
However in TextBox1 I get:
System.Windows.Forms.DataGridViewSelectedCellCollection
I'm thinking it isn't as simple as it seems. I'm a C developer just learning VB.NET.
