Answer 1

I think the PromptCharacter attribute is what you are looking for. Sample taken from the Ajax Control Toolkit homepage, with attribute added.

<ajaxToolkit:MaskedEditExtender
TargetControlID="TextBox2" 
Mask="9,999,999.99"
MessageValidatorTip="true" 
OnFocusCssClass="MaskedEditFocus" 
OnInvalidCssClass="MaskedEditError"
MaskType="Number" 
InputDirection="RightToLeft" 
AcceptNegative="Left" 
DisplayMoney="Left"
ErrorTooltipEnabled="True"
PromptCharacter=" "/>
