Custom zoom

If you want to disable the scrolling behavior when the Control key is pressed, you can use the following custom implementation:  

        public class CustomGrid : RadGridView
        {
            public override string ThemeClassName
            {
                get
                {
                    return typeof(RadGridView).FullName;
                }
            }
            protected override void OnMouseWheel(MouseEventArgs e)
            {
                if (System.Windows.Forms.Control.ModifierKeys == Keys.Control)
                {
                    return;
                }
                base.OnMouseWheel(e);
            }
        }

Hello, Dess,

thanks for your quick reply. Yes, the Font is enlarged. It's applied in the FontChanged event, but I suppose it doesn't matter a lot. The AutoSizeRows property seemed like a good idea but it works only for single line strings. It's logical that for multiline text the row gets higher to show its full content. But that's the problem - I don't want this behavior. Users can store quite long texts in some columns and it wouldn't look good. The grid serves as a quick overview, it's not important to show whole texts, just the first line. I have Multiline and WrapText set to false, but with AutoSizeRows, it always shows everything. So I tried to set row height manually, which worked only partially as I wrote in the first post.

I hope I described my intentions in an understandable way.

I didn't try the scrolling suggestion yet, but it seems like it should do the trick, thanks.

Regards,

Tomáš

Hello, Dess,

I just wanted to inform you that I found a way how to resize all the parts of grid. So consider this solved. But another issue popped up - when I use a Metro or Metro Blue theme, changing the font size doesn't have any effect on the grid - the font size remains still the same.

Any ideas on this? Thanks

Tomáš

        Font f = new Font("Arial", 10f, FontStyle.Regular);
        private void radGridView1_ViewCellFormatting(object sender, CellFormattingEventArgs e)
        {
            e.CellElement.Font = f;
        }

You can manage the font size dynamically during the application's execution. Once the font is edited, you need to force the ViewCellFormatting event by calling the MasterTemplate.Refresh method.

In case you are still experiencing any further difficulties, it would be greatly appreciated if you can provide more details about the exact implementation that you have on your end. Thus, we would be able to integrate this approach in my sample project and provide further assistance. Thank you in advance

I am looking forward to your reply.

Hello, Dess,

thank you, the ViewCellFormatting event was the right place, the font changes correctly now. I am not sure why for all other themes it was good enough to just set the new font like this: ragGridView1.Font = new Font("Arial", 10f, FontStyle.Regular), but I guess I don't have to know everything.

Thanks again for your time.

Regards

Tomáš
