ajax:MaskedEditExtender

Hello,

I am having a textbox control inside a DataGrid in my Project. It has to only take in decimal values, with 7 numbers in the fraction part.

I used the ajax:MaskedEditExtender for this and got the fraction part right. But when i click into the textbox moving the cusor some places left of the decimal and then i try to press the dot, the cursor does not move to the right of the decimal. I have to press dot once again to move the cursor right of decimal.

Is there any solution for this?

 My code is like this :

<ajax:MaskedEditExtender ID="MaskedEditExtender1" runat="server" TargetControlID="TxtRate"
  Mask="99999.9999999"  MaskType="Number" InputDirection="RightToLeft" OnFocusCssClass="MaskedEditFocus" OnInvalidCssClass="MaskedEditError" PromptCharacter=" " />

Thanks

Yasir
