For a Data Grid in a Win Form, when the user selects a row and then presses
the Enter key, how do I capture that the user pressed the enter key? 3 7283
Hi,
First of all, I would like to confirm my understanding of your issue. From
your description, I understand that you need to know how to handle the key
press event in a DataGrid. If there is any misunderstandin g, please feel
free to let me know.
This depends on how your datagrid looks like. If the selection is to the
whole row (The whole row is highlighted), you can handle the
DataGrid.KeyDow n event to achieve this.
private void dataGrid1_KeyDo wn(object sender,
System.Windows. Forms.KeyEventA rgs e)
{
if(e.KeyCode == Keys.Enter)
{
MessageBox.Show ("Enter key pressed");
}
}
When the focus is in a datagrid cell, the above keydown event will not get
fired. We need to do the following:
Add this line in InitializeCompo nent(),
this.dataGrid1. ControlAdded +=new
ControlEventHan dler(dataGrid1_ ControlAdded);
Then add this:
private void dataGrid1_Contr olAdded(object sender, ControlEventArg s e)
{
e.Control.KeyDo wn +=new KeyEventHandler (Control_KeyDow n);
}
private void Control_KeyDown (object sender, KeyEventArgs e)
{
}
However, in this case, we can use the above method to handle all the key
event except the Enter key and some other control keys. Because the event
is NOT fired when Enter key is pressed. This is by design. So I suggest you
stick to the first method to handle DataGrid.KeyDow n event.
HTH.

How do I force the Data Grid to only select rows and not select cells? If
the user can only select rows this will work for me because I'm using the
Data Grid to show available License Dealers to select from.
Thanks for your last response, it was easy to understand and worked. If
only I can set the Data Grid to select rows only then it will be perfect.

Hi All!
I would like to make my WinForm DataGrid control so that user could easily
edit the items in the **related table**.
For instance, I have customers table and it has one-to-many relationship
with the customerType table. I would like the WinForm DataGrid to display a
column with "Customer Type" where users can select the type of customer from
a drop down list.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.

For most users, this new feature is actually very convenient. If you want to control the update process,...
