I have couple of questions with datagridview 1.How to handle the Enter-Key when the user edited the columns value.?I mean, without changing the columns values we can suppress the enter-key by following. No problem. It's working Fine.
Private Sub DataGridView1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles DataGridView1.KeyDown
If e.KeyCode = Keys.Enter Then
Dim numCols As Integer = DataGridView1.ColumnCount
Dim numRows As Integer = DataGridView1.RowCount

But after if I select any one column & changed the values then if I press <Enter> it's moving to next row. But I want to move it to next column..
2. With Datagridview - I have a column for date. and it's defaut format is mm/dd/yyyy. But Iam looking to read the date by "dd/mm/yyyy" format. Also if the user feed wrong date format then it has to display my Error message. "INVALID DATE"
I have 5 textboxes embedded in a datagrid that require a date format (mm/dd/yy), but can be left empty if user doesn't have date. User can poplutes these textboxes for multiple records and hit submit button. On the submit i loop through the grid. If dates are populated AND they are in the correct format then I call a stored procedure that inserts the record into a table. If any of the dates that are populated in the textbox is not a date or in the incorrect format I need to display error message in a label. I got all this to work, but if it throws error message all the data in the grid is wiped out.
How can i keep data in each textbox and still display the error message?

View 21 RepliesI would like to create a multicolumn list of items, similar to the right pane of the Windows Explorer window. There are rows, one for each item. And there are columns similar to the filename, size, date of last modification, etc. columns of Windows Explorer. The data supplied to the control will be individually extracted from files. (I mean, no database, no spreadsheet is available as a source.)
Question: Which control is the best for this purpose? I tried listbox, but it seems "multicolumn" means not what I'm used to in Excel VBA.
