Thank you very mcuh, i will try this and let you know as soon as I am done converting it over to vb

Thank you very much for your help, I believe it will work as soon as I convert this to vb.net, I am a bit rusty on my c#, especially when you try to assign the eventhandlers....but i will look it up, (unless of course you can do this quicker then I can....)

Hi,

Okay, it's possible to disable the mouse wheel, but it requires a bit of work. When the cell goes into edit mode, the grid places a derived TextBox control over the cell and it is this TextBox that handles the MouseWheel. So you have to get a reference to the TextBox and handle it's MouseWheel event and then mark it handled.

Here's some code that worked for me in a small sample:

        private void ultraGrid1_ControlAdded(object sender, ControlEventArgs e)
        {
            EmbeddableTextBox textBox = e.Control as EmbeddableTextBox;
            if (textBox != null)
                textBox.MouseWheel += new MouseEventHandler(textBox_MouseWheel);
        }

        private void ultraGrid1_ControlRemoved(object sender, ControlEventArgs e)
        {
            EmbeddableTextBox textBox = e.Control as EmbeddableTextBox;
            if (textBox != null)
                textBox.MouseWheel -= new MouseEventHandler(textBox_MouseWheel);
        }

        void textBox_MouseWheel(object sender, MouseEventArgs e)
        {
            HandledMouseEventArgs args = e as HandledMouseEventArgs;
            if (args != null)
                args.Handled = true;
        }

A ValueList is what I am manually populating and passing by reference to the grid.displaylayout.band(0).columns(index).valuelist = list The cellis in edit mode at this point, and whenever i use the scroll mouse button (middle one) is when this happens... No sample project able to send, I am working in a project that has 1000s of modules and classes, and of which I would have to sign a waver before sending code The closest thing I can come to giving you the exact nature of the problem, is whithin any generic grid, add the value list manually, but leave the field editable by the user, and then once you set your focus within that cell containing the valuelist, type in a manual entry and then apply the scroll wheel from the mouse, and you will see your manual entry disappears.

Hi,

I'd be happy to try to help, but there are too many unknowns here for me to guess at this point.For example, how are you providing the dropdown for the cell? A ValueList? An UltraDropDown? An UltraComboEditor? An UltraCombo?

And what version of the controls are you using?

Where exactly is the mouse - over the cell? Is the cell in edit mode?

If you could post a small sample project here which demonstrates the problem, I'd be glad to take a look and see if I can figure out what's going on and how to stop it. :)
