Comments: hello everybody, I suffered the same issue. To work around this I have implemented a custom ToolkitScriptManager that basically add a JS to Fix this problema. This is my custom class: ``` Public Class ToolkitScriptManagerCustom Inherits ToolkitScriptManager Protected Overrides Sub OnPreRender(ByVal e As System.EventArgs) MyBase.OnPreRender(e) Dim sb As New StringBuilder sb.AppendLine("<script>") sb.AppendLine("function FixMaskedEditExtender() {") sb.AppendLine("if (!Sys) return;") sb.AppendLine("if (!Sys.Application) return;") sb.AppendLine("var els = Sys.Application.getComponents();") sb.AppendLine("if (!els) return;") sb.AppendLine("for (i = 0; i < els.length; i++) {") sb.AppendLine(" if (els[i]._name == ""MaskedEditBehavior"") {") sb.AppendLine(" var mk = els[i];") sb.AppendLine(" var el = mk._element;") sb.AppendLine(" if ($) {") sb.AppendLine(" $(el).blur(function(event) { $(this).val($(this).val().replace(new RegExp(mk._PromptChar, ""g""), '')); });") sb.AppendLine(" } else {") sb.AppendLine(" el.setAttribute(""onblur"", ""this.value = this.value.replace(new RegExp("" + mk._PromptChar + "", 'g'),'');"");") sb.AppendLine(" }") sb.AppendLine(" }") sb.AppendLine("}") sb.AppendLine("}") sb.AppendLine("Sys.Application.add_load(FixMaskedEditExtender);") sb.AppendLine("</script>") Dim l As New LiteralControl(sb.ToString()) Me.Controls.Add(l) End Sub End Class ``` I hope this can help somebody
