Rad Filter Default on Page Load

[rik butcher]

is there a way in the code behind on page load to automatically make the rad filter default as if a user has clicked
the "And" - see screenshot
. it would be great if i could default this to behave as if the user had clicked the "Add Expression" button.
any help is appreciated.
thanks again

Hello Rik,

You could achieve your scenario by following the demo below which shows the same functionality implemented. The idea is to add expression to the RadFilter RootGroup Expressions collection by calling the AddExpression method.

i just want a "click" event to be triggered by "page Load" - not build the whole filter all over again.

Hi Rik,

If you want to focus the input element from the filter you could use the code below to achieve your scenario.

<telerik:RadScriptBlock runat="server">
    <script>
        function pageLoad()
        {
            setTimeout(function()
            {
                var input = document.getElementById("<%= WorkOrdersRadFilter.ClientID %>").getElementsByTagName("input")[0];
                if (input.className == "rfText")
                {
                    input.focus();
                }
            }, 100);
        }
    </script>
</telerik:RadScriptBlock>

Kind regards,

so, i assume theres NO WAY to do this in the code behind, correct?

i guess i'm asking for a lot, but there is an event that causes a postback when the user clicks the "add expression" section of the rad filter.
i'm simply trying to do that very same thing.
we have mutiview screens w/ separate rad filters on them and it would be handy when a used clicked one of those tabs if that particular filter would also mimick in the code behind the same event that happens when they click the "add expression".
if no one can do this, just let me know its a limitation of the control. but, i can't help but be curious at this point. since our whole application is nothing but telerik controls.
thanks

Well I figured this out myself. this is exactly what i was asking for and looking for to happen in the code behind.
Not a Link to a Tutorial - i already know where those are.

 

 

RadFilterStartsWithFilterExpression expr1 = new RadFilterStartsWithFilterExpression("WORKORDERNUMBER");

 

expr1.Value =

 

"";

 

WorkOrdersRadFilter.RootGroup.AddExpression(expr1);
