Hello,

I am adding an example that shows how you can use the client side MouseDown of the WebMonthCalendar to retain the selection and also show a context menu.

Client side code:

function WebDataMenu1_ItemClick(sender, eventArgs) {
    alert(eventArgs.getItem().get_text() + $find("WebMonthCalendar1").get_selectedDates());
}
 
function WebMonthCalendar1_MouseDown(sender, eventArgs) {
    if (eventArgs._props[0].button == 2) {
        // the following will allow you to retain the selection on the right mouse button down.
        eventArgs.set_cancel(true);
        var menu = $find("WebDataMenu1");
        menu.showAt(null, null, eventArgs.get_browserEvent());
    }	
}

Markup:

<ig:WebDataMenu ID="WebDataMenu1" runat="server" IsContextMenu="True">
    <Items>
        <ig:DataMenuItem Key="Edit" Text="Edit">
        </ig:DataMenuItem>
        <ig:DataMenuItem Key="Cancel" Text="Cancel">
        </ig:DataMenuItem>
    </Items>
    <ClientEvents ItemClick="WebDataMenu1_ItemClick" />
</ig:WebDataMenu>
    
<ig:WebScriptManager ID="WebScriptManager1" runat="server">
</ig:WebScriptManager>
<ig:WebMonthCalendar ID="WebMonthCalendar1" runat="server" 
    SelectionType="Multi">
    <ClientEvents MouseDown="WebMonthCalendar1_MouseDown" />
</ig:WebMonthCalendar>

Let me know if you have any questions with this matter.

Hello Arsalan_bs,

Our controls handles on click, so when you make a right button click the expected is the selection to be lost. You can handle mouse click on the control and to save the selected items and set them selected after that depending on the scenario that you need to implement. And this will be a custom implementation.

If you need further assistance with this matter do not hesitate to contact me.

Sincerely,
