How to select a row in a DataGridView on MouseDown

8 New Member
Hello,

This is really frustrating me. I am trying to get my application to select an entire row in my DataGridView on MouseDown. I can get it to select the whole row on MouseUp no problem, but it will not do it on MouseDown. I would think this would be extremely easy, but for some strange reason, no matter what I try, it just doesn't do it. Can anyone help me with this? Here is the code that I think should work:

private void dgMyGrid_CellMo useDown(object sender, DataGridViewCel lMouseEventArgs e)
{
dgMyGrid.Rows[e.RowIndex].Selected = true;
}


Thanks!!!

Is there such an event available or do you have to use a custom event handler?

There is an event for CellMouseDown already. And the properties of e give me row index and column index and such. The event fires when the mouse button is pressed down overtop of a cell on your DataGridView (the new DataGrid). I've searched the MSDN site which gives some examples of using this event. Their example pops up a MessageBox on CellMouseDown, which tells you the column/row location of the cell you clicked. I reproduced their example, and the MessageBox does pop up on MouseDown, but regardless of what I try, the row won't select on MouseDown.
I've also tried using just the regular MouseDown even (instead of CellMouseDown), but e doesn't give you RowIndex or Column index, so that is not as useful of an event. And regardless, it doesn't work either. For either, when I do mouse down just the single cell highlights. Then if I recall correctly, on mouse up is when the whole row selects (I have since changed the events to MouseUp so I'm not sure of the prior behavior. I'm still trying to get it changed to on MouseDown/CellMouseDown though).

It's the weirdest thing. It's like their event doesn't work right.

Grrr... I'm still hoping to figure this out. If I can't figure it out today then I'll probably just be leave it happening on the MouseUp event.

In an application I am writing I use both double click and mousedown, first for playing a track, second for doing a drag. Problem is that , unlike explorer, teh listview does not select the item under the mouse, but does so after a click.. Is there any way to change that behaviour in VB.NET or is there a work around? As it is now the on mousedown the previously selected item is dragged, not the one under the mouse..

Hello, I have a datagridview that is too wide for the form, so I'm trying to put scrollbars on the form and the datagridview table.

I need a DataGridView in which, if the user clicks on a cell, the entire row is selected. But if the user clicks on a cell with the control-key down, the selected row does not change. I thought I should be able to just set SelectionMode to something like "NoSelect", then I could capture the MouseDown event and set Row.Selected to true when I need to. Apparently, there is no "NoSelect" option for SelectionMode. Anyone know how to do...
