Customise Filter Expression Text

[Fergal]

Is it possible to edit the display text for the RadFilter Expressions? For instance, on the RadFilter, you see an Expression for "StartsWith" - is it possible to edit that text (to enter a space for example: "Starts With"), but not actually change the functionality of the expression object?

I don't want to have to implement my own set of expressions, just alter the display text of the items already there.

Thanks
Fergal

Hi,

Try setting the following.
aspx:

<telerik:RadFilter ID="RadFilter" runat="server" Localization-FilterFunctionStartsWith="Starts with"></telerik:RadFilter>

Thanks,
Shinu

Looks like exactly the feature I wanted, thanks!

Next Question: Can I change the text in the Expression Preview?

For example, I've changed "IsNull" to display "IsPresent" - I'd like to write that out in the Expression Preview in a user readable format that matches the display text.

Hello Fergal,

In order to achieve this you can use this code snippet:

function pageLoad(sender, args)
        {
            var filter = $find("<%=RadFilter1.ClientID %>");
            var menu = filter.get_contextMenu();
            menu.add_showing(FilterMenuShowing);

            var elements = document.getElementsByTagName("a");
            for (var i = 0; i < elements.length; i++)
            {
                if (elements[i].className && elements[i].className.indexOf("rfExp") != -1 &&
                    elements[i].innerHTML == "IsNull")
                {
                    elements[i].innerHTML = "IsPresent";
                }
            }
        }

        function FilterMenuShowing(sender, args)
        {
           sender.findItemByValue("IsNull").set_text("IsPresent");
        }

In the example provided the IsNull value is replaced both in the field editor and in the context menu.

All the best,
