View 2 RepliesIn a DatagridView I have databound checkboxcolumns. But if I check or uncheck multiple checkboxes, not all changes are saved. (It doesn't trigger the property Set method on all, maybe on every 2nd). However if I after each checkbox-click, click on another cell (column) before the next checkbox, then all actions will trigger the Set methods. So it seems the cell validation does

View 8 RepliesIs is it possible to add trailing text after the checkbox for a Datagridview CheckBoxColumn?
The situation is like this. Say the DataGridView shows name of employees from datatable. The user can select employees from the displayed list in the DGV. For the selection, I inserted a checkboxcolumn into the datagrid. Everything OK.
But just want to know whether it is possible to merge the two column into 1, so that the check box precedes the name of the employee in the same cell rather than in a different column.
how can I get the checkboxcell value for each row on the click of a button?

View 1 RepliesI have a datagridview with contacts on a form with clients. The underlying table for contacts has a field for Contactnumber. This is a identity column so its new number is generated by SQL Server.
I add a row and when I move to the next record on the form, the form �nd the information in the datagrid is saved to the database. So far, so good. The problem is: when I move back and try to delete that newly made row I get an error about concurrency.
It's logical actually, the record is saved, but the dataset of the datagrid doesn't yet know what the new contactnumber is. Apparently it's not information that it gets back automatically from SQL Server.
How can I make the dataset know the new identity of the row that is saved to the database? I use a simple da.Update(dsVerwijderingen, Tabelnaam) to save the changes to the database.

I saved a text file. The text characters were in RichTextBox iwth multiple lines. I used
RichTextBox1.AppendText(ControlChars.Cr) or RichTextBox.AppendText(ControlChars.Lf)
at the end of each line, but when I opened this text file using NotePad, all lines were displayed with ONE line. The strange thing is: if I open the same text file using other editors, .e.g. an IDE of Microchip or Freescale or Multi-edit...the text display had multiple lines as expected.
What should I do to make display as expected in NotePad?
