LinkButton Mode Opens Two Windows when target is _blank

Hi Charles,

I have already replied to the forum post that was opened by you on the matter, so that I paste my answer below for the rest of the community:

I confirm this is an issue with the control. I have logged it here (
http://feedback.telerik.com/Project/108/Feedback/Details/163485), so that you can comment and monitor its progress

For the time being you can use the following JavaScript workaround:

Copy Code

<telerik:RadButton ID="radbtnVehicleList" runat="server" Text="Google" Skin="Default" Width="200px"

    NavigateUrl="http://www.telerik.com" ButtonType="LinkButton" AutoPostBack="false" Target="_blank">

</telerik:RadButton>

<script>

    Telerik.Web.UI.Button.NavigationFunctionality.prototype = {

        clicked: function (ev) {

            var that = this;

 

            that.base.clicked(ev);

 

            that._handleNavigateUrl();

        },

 

        _handleNavigateUrl: function () {

            var that = this,

                target = that.options.navigateTarget,

                url = that.options.navigateUrl;

 

            if (!url) return;

 

            if (target && target == "_blank")

                window.open(url);

            else if (target && target == "_parent")

                window.parent.location.href = url;

            else if (target && target == "_top")

                window.top.location.href = url;

            else if (!target || target == "_self")

                window.location.href = url;

            else {

                var targetFrame = $("iframe[name='" + target + "']").get(0) ||

                                    $("frame[name='" + target + "']").get(0) ||

                                    $("#" + target).get(0);

 

                if (targetFrame && targetFrame.tagName.toLowerCase().indexOf("frame") > -1) {

                    targetFrame.setAttribute("src", url);

                } else if (target) {

                    window.open(url, target);

                }

            }

        }

 

    };

</script>
