I found a thread on how to set the RadSpinEditor buttons size using the designer, but I haven't been able to get it to work programmatically..
radSpinTest.SpinElement.ButtonUp.MinSize.Width = 45 <--- this doesn't work because it's a readonly property
Any help would be greatly appreciated.
I don't see a way to remove my thread after solving it myself, but here is the answer:
spinTest.SpinElement.ButtonUp.MinSize = New System.Drawing.Size(50, 25)
spinTest.SpinElement.ButtonDown.MinSize = New System.Drawing.Size(50, 25)
