Answer 1

Google chrome has such more issues with controls. You can specifically check version you are running on & what ascii values it takes? when you try to use keys. One more thing, check your textbox markup whether it is correct or not?

Answer 2

below code works fine, replace TargetControlID="txtPhone" by your text field id.

<ajax:MaskedEditExtender ID="textPhone_MaskedEditExtender" MaskType="None" runat="server"
                                CultureAMPMPlaceholder="" CultureCurrencySymbolPlaceholder="" CultureDateFormat=""
                                CultureDatePlaceholder="" CultureDecimalPlaceholder="" CultureThousandsPlaceholder=""
                                CultureTimePlaceholder="" Enabled="True" TargetControlID="txtPhone" Mask="(999)-999-9999"
                                AutoComplete="true" ClearMaskOnLostFocus="false" CultureName="en-US">
                            </ajax:MaskedEditExtender>

Answer 3

It seems this was a bug in the MaskedEditExtender. See this CodePlex issue.

You could try updating to the latest version at it states it was fixed in the April 2013 release.

Alternatively there is a small fix available here.

Add below code, it should work fine.Thanks.

protected void Page_Init(object sender, EventArgs e)
        {
            try
            {
                if (!ClientScript.IsStartupScriptRegistered(GetType(), "MaskedEditFix"))
                {
                    ClientScript.RegisterStartupScript(GetType(), "MaskedEditFix", String.Format("<script type='text/javascript' src='{0}'></script>", Page.ResolveUrl("../Javascript/MaskedEditFix.js")));
                }
            }
            catch (Exception ex)
            {
