.NET Forum / Windows Forms / WinForm General / October 2005MULTISELECT DATAGRID
Is there a good way to get an arraylist of all selected rows in a datagrid without loop through all the rows of its dataview ??? I have a great number of rows shown on the datagrid. For the performance of the application I think it's no a good idea to loop through all the rows to test IsSelected (Row) property. Many thanks  SignatureNQ Hi.. I think partially you can do this in following way... in Grid Click event get the HitTestInfo.. this one returns the hti.Row and hti.Column. Store this ht.Row in arrayList and get the Primary Key out of this. Now, from the table do Find on Table with Primary Key so that you can get the individual row and you don't have to do isSelected from dagarid. Let me know if you want code snippet then I can provide that also.

I would use the CTRL and the CAPS options to select more than one row at the same time and the mouse dragging it through the rows of the datagrid selecting and unselecting the rows. Then I would like to get all the rows selected...

I dont understand what do you mean by dragging, but as I understand when you press the CTRL button, you can catch which button was pressed in KeyUp or KeyDow or MouseUp event. Store first hti.Row in temperory variable and check in those events if CTRL is pressed with left mouse button click , if yes then select all the rows which are between first hti.Row and second hti.Row. by datagrid.select[hti.Row,hti.Column] get the primary key values of the rows and do DataTable.Find and get the individual rows. And pass that row collection to some other form... As I understand you want to do multiple select as we do in Excel by pressing SHIFT button ok I reached the result Many thanks... > > This solution doesn't work as I would like. > > I would use the CTRL and the CAPS options to select more than one row at the [quoted text clipped - 15 lines] > As I understand you want to do multiple select as we do in Excel by > pressing SHIFT button Free MagazinesGet these publications absolutely FREE for up to 12 months.
