How to dynamically change font size of Grid

[Peter Meinl]

I wont to let the user change the font sizes of a GridView using a Slider (like in Excel 2007) so he can see more data if he chooses a smaller font.
How cant I do this?

Hi Peter Meinl,

Do this when your slider value changes:

this.grid.FontSize = 30; //I have hard-coded this but you will use the real value here.
this.grid.UpdateLayout();

This should do it.

And how do I change RowHight and ColumnWidth's proportionally?

Hi Peter Meinl,

You can't do that at run-time. When you change the font and update layout cells are automatically adjusted.

Kind regards,

In my test the cell hight does ony adjust when the font size gets very big. It does not adjust when I select a smaller font size (see screenshot attached). There seems to be MinRowHight which I do not know how to change.

 

    Private Sub slidFontSize_ValueChanged(ByVal sender As Object, ByVal e As System.Windows.RoutedPropertyChangedEventArgs(Of Double)) Handles slidFontSize.ValueChanged
        RadGridView1.FontSize = e.NewValue
        RadGridView1.UpdateLayout()
    End Sub

How can I make the cell hight and width adjust too?

Hi Peter Meinl,

Can you send me your test project. I will try to think of something, but I am not sure that this will be possible.
