ContextMenu Postback Arguement

[Ben Gripka]

I am brand new to the telerik controls so this my be very simple.

I have created a context menu that will open anywhere in the document when text is selected.  The text that is selected will be used in the context menu to replace the text of a few items that have [Selection] in their text.

All of this is working the problem I am having is getting the selection text when the user clicks on a menu item and a postback occurs.  Is this possible?

        <script type="text/javascript">

            function getSelText() {

                var txt = '';

                if (window.getSelection)

                    return window.getSelection();

                else if (document.getSelection)

                    return document.getSelection();

                else if (document.selection)

                    return document.selection.createRange().text;

                else 

                    return new String("");

            }

            function onClientShowingHandler(sender, eventArgs){

                var cancel = (getSelText().length == 0);

                eventArgs.set_cancel(cancel);

                if (!cancel) {

                    var selection = getSelText();

                    sender.set_clientState(selection);

                    var items = sender._getAllItems();

                    for (var i = 0; i < items.length; i++) {

                        items[i].set_text(items[i].get_text().replace("[Selection]", selection));

                    }

                }

            }

        </script> 

        <telerik:RadContextMenu ID="RadContextMenu1" 

            OnClientShowing="onClientShowingHandler"

            OnItemClick="RadContextMenu1_OnItemClick"

            CollapseAnimation-Type="None" ExpandAnimation-Type="None" runat="server">

            <Targets>

                <telerik:ContextMenuDocumentTarget />

            </Targets>

            <Items>

                <telerik:RadMenuItem Text="[Selection] is a Manufacturer" Value="Manufacturer" />

                <telerik:RadMenuItem Text="[Selection] is a Vendor" Value="Vendor" />

                <telerik:RadMenuItem Text="Copy" />

            </Items>

        </telerik:RadContextMenu>

Hello Ben Gripka,

Please wrap the code in track / commit changes:

function onClientShowingHandler(sender, eventArgs){
                var cancel = (getSelText().length == 0);
                eventArgs.set_cancel(cancel);
                if (!cancel) {
                    var selection = getSelText();
                    //sender.set_clientState(selection);
                    sender.trackChanges();
                    var items = sender.get_allItems();
                    for (var i = 0; i < items.length; i++) {
                        items[i].set_text(items[i].get_text().replace("[Selection]", selection));
                    }
                    sender.commitChanges();
                }
            }

I hope this helps.

All the best,
