Hello Codey McCodesalot,
Unfortunately, at present there is no property that controls the dimensions of the dialog of RadSpell, because the content of the dialog - buttons, textareas, etc are not automatically resizable. Your approach to set width and height to RadWindow (we are using it to load the spellcheck dialog inside it) is the right one, however you have a mistake in the selector.
... Actually instructs the browser to set width and height to each <div />
element that is in the .RadWindow.RadWindow_MyCustomSkin.rwNormalWindow.rwTransparentWindow
parent, and this makes things that terrible. You need to refer only the parent class in order to set new width and height to the control, i.e:
However, please, have in mind that this will not make the controls inside automatically fit to the new dimensions, and you will need to set new values in your custom skin.
Have a great weekend,
