RadFilter. Prohibit some boolean operators in filter expressions

[Ivan]

Hello Telerik team,

First of all, thank you for bringing web components, to the next level! 

I would like to ask, whether there is a way to remove some boolean operators, e.g. all except for AND, to simplify filter expression? We need to simplify end user experience, hence would like to remove unnecessary options (OR, NOT OR, NOT AND).

Thanks in advance!

Hello Ivan,

You can use the following code snippet in order to reduce the options in the menu for RadFilter

<script type="text/javascript">
                function pageLoad()
                {

                    $find('<%=Filter.ClientID %>').get_contextMenu().add_showing(
function (sender, args)
{
    sender.findItemByValue("Or").set_visible(false);
    sender.findItemByValue("NotAnd").set_visible(false);
    sender.findItemByValue("NotOr").set_visible(false);
}
);
                }
            </script>

Best wishes,

I need do this in code behind.

Hello Julieta,

You can remove the NotAnd and NotOr group operations server-side as shown below:

protected void Page_Load(object sender, EventArgs e)
{
RadFilter1.Localization.GroupOperationNotAnd = "";
RadFilter1.Localization.GroupOperationNotOr = "";
}
