• laiseng Position of selected cell

  How do i find the position ( not the index of row and cloumn)of selected cell in a dataviewgrid I need it to place a control over the grid. Thanks. Regards Alu thanks alot! :) Regards Alu According to whether you want the display area or the client area you use one of the following: 1. For the display area of the currently selected cell: Rectangle rec = grd.GetCellDisplayRectangle(grd.CurrentCell.ColumnIndex, grd.CurrentCell.RowIndex, false); the last argument, when true, returns only the displayed portion of the cell, when false, returns the whole cell. 2.

• R2ks Capturing Key Events

  Hi, I have a form that I want to respond to some key events. On the form is also a numericUpDown. It seems that the numeric is picking off the key events so that the code that I want to run for some specific events is not happening. Any know of how to deal with this Thanks Much.

Also, you can prevent up/down keys ever get to the NumericUpDown control...: private void form1_KeyDown( object sender, KeyEventArgs e) {     if (e.KeyCode == Keys .Up)     {         // Process a key here         e.Handl ...Show All

• Shrek.NET Auto Resize Form Controls when Screen resolution changes?

  Well, what the title says. I have been doing my GUI in a 1600x1200 resolution, but when i took my project home to continue working on it, well it doesnt fit my Widescreen, nor my 19'incher. Is there a way to automatically resize the form i have been reading about anchoring but it seems they only work for forms maximize and minimize, not when im switching resolutions! Any help would be great. Thanks! Anchor and Dock will help only to resize controls on the form but not the form itself. But you need 2 things: 1) Resize your form according to the resolution. 2) Controls also need to be resized upon resizing the form. (This can be done with Anchor and Dock properties).
