Menu re-opens after exporting from a grid

[bdrennen]

I have a page with a RadGrid. Several functions for the grid are in a RadMenu. Several of the functions trigger a JavaScript function to open dialogs, windows, and whatnot, while another menu item does a postback to export the contents of the grid to a .csv file. Everything works fine, with the exception of the export. The menu works properly up to the point where the postback completes and the .csv begins downloading. At that point, the menu re-opens with the Export item highlighted. Is there any way to keep the menu from re-opening after the export is complete?

Here's my menu:

<telerik:RadMenu ID="RadMenu1" runat="server"
    ExpandDelay="0"
    CollapseDelay="0"
    ExpandAnimation-Type="None"
    CollapseAnimation-Type="None"
    ShowToggleHandle="true"

    OnItemClick="RadMenu1_ItemClick"
    OnClientItemClicking="OnClientItemClicking"
    ClickToOpen="true"

    Skin="Windows7"
>
    <Items>
        <telerik:RadMenuItem Text="Menu" PostBack="false">
            <Items>
                <telerik:RadMenuItem Text="Save..." />
                <telerik:RadMenuItem Text="Save As..." Enabled="false" Visible="false" />
                <telerik:RadMenuItem Text="Delete" Enabled="false"/>

                <telerik:RadMenuItem Text="|" runat="server" IsSeparator="True" />

                <telerik:RadMenuItem Text="Schedule..." />
                <telerik:RadMenuItem Text="Export" />
                <telerik:RadMenuItem Text="Print" />

                <telerik:RadMenuItem Text="|" runat="server" IsSeparator="True" />

                <telerik:RadMenuItem Text="Reset Grid" />
            </Items>
        </telerik:RadMenuItem>
    </Items>
</telerik:RadMenu>

 

Here's the JavaScript that sits behind the menu:

 

function OnClientItemClicking(sender , args) {
    var itemText = args.get_item().get_text();

    switch(itemText) {
        case "Save...":
            args.set_cancel(true); // Cancel postback
            window.radopen("SaveQueryForm.aspx?KEY=<%= _queryKey %>&user=<%= _username %>&saveKey=<%= _saveKey %>", "RadWindow1");
            break;
        case "Save As...":
            args.set_cancel(true); // Cancel postback
            window.radopen("SaveQueryForm.aspx?KEY=<%= _queryKey %>&user=<%= _username %>", "RadWindow1");
            break;
        case "Delete":
            args.set_cancel(true); // Cancel postback
            window.radopen("DeleteQueryForm.aspx?savekey=<%= _saveKey %>&&user=<%= _username %>", "RadWindow2");
            break;
        case "Schedule...":
            args.set_cancel(true); // Cancel postback
            window.radopen("ScheduleForm.aspx?KEY=<%= _saveKey %>&user=<%= _username %>", "RadWindow3");
            break;
        case "Print":
            args.set_cancel(true); // Cancel postback
            openForm();
            break;
    } // end switch

    if (itemText != "Menu") {
        closeMenu();
    } // end if
} // end OnClientItemClicking

function closeMenu() {
    var menu = $find("<%=RadMenu1.ClientID %>");
    var item = menu.findItemByText("Menu");
    item.close();

    setTimeout(function() {
        menu.close();
    }, 0);
} // end closeMenu

 

The codebehind that handles the export:

protected void RadMenu1_ItemClick(object sender, RadMenuEventArgs e) {
    switch (e.Item.Text) {
        case "Export":
            exportGridToCSV();
            break;
    } // end switch
} // end RadMenu1_ItemClick

protected void exportGridToCSV() {
    RadGrid1.ExportSettings.ExportOnlyData = false;
    RadGrid1.ExportSettings.IgnorePaging = true;
    RadGrid1.ExportSettings.OpenInNewWindow = true;
    RadGrid1.ExportSettings.FileName = ("Student Data Export - " + DateTime.Now.ToShortDateString()).Replace(' ', '_');

    RadGrid1.MasterTableView.ExportToCSV();

} // end exportGridToCSV

 

Any ideas on what I can do to keep the menu from re-opening after the export?

Hello,

This is a known issue and it has been logged for fixing. It is a regression and it is working correctly with 2016 R2 504 You may use the following Ideas & Feedback Portal item to track its status, vote for it and add comments. I am afraid that currently there is no workaround for this issue.

Feel free to contact us again, if you have any questions.

Aha! Thank you for letting me know there currently isn't a workaround--this was driving me batty. I'll keep a lookout for the fix in a future release.
