TextBox scaling with Microsoft Sans Serif font

[Frank Beerens]

Hi,

When I use a telerik textbox, and set the font to Microsoft Sans Serif (size 11,25 pt) (see A in the attachment), some characters are not displayed fully. When I use Segoe UI it is rendered correctly (B in the attachment). Looks like the scaling of the component does not work 100%. Setting autosize to false does not work either: I am able to scale the control, but the 'inner textbox' stays too small.

Best Regards

Hello Desislava,

There is no relation between my two posts. This has noting to do with DPI scaling or whatsoever.

To reproduce this problem:
Create a winforms project, put two radtextboxes on a form, and set the font of one of them to Microsoft Sans Serif (size 11,25 pt).
When you type a character like 'g', the lower curve of the character is not painted correctly.

It also happens when using a combobox. The lower parts of the characters dissapear when using Microsoft Sans Serif 11.25 pt.

Hello Frank,

Following up on this case, it appears that this is a known issue which we already have in our feedback portal: http://feedback.telerik.com/Project/154/Feedback/Details/110711-fix-radtextbox-text-is-cut-from-below

As you can see in the description, the workaround is to set a MinimumSize to the inner text box. You can also see how to use TextMeasurer to measure the height of the text so that the text box sizes correctly with all fonts.

this.radTextBox1.TextBoxElement.TextBoxItem.HostedControl.MinimumSize = new Size(0, 20);
this.radDropDownList1.DropDownListElement.TextBox.TextBoxItem.HostedControl.MinimumSize = new Size(0, 20);

I hope you find this useful. Should you have any other questions, do not hesitate to write back.
