[Solved] filter by text string

[Hetal]

hello..

generally we use filter as follows in code...

var enteredFilterStr = null;
gridPersons.filter("");
enteredFilterStr = "FNAME~substringof~'" + $("#FNAME").val() + "'";
gridPersons.filter(enteredFilterStr);

but my requrement is I want to compare just 1st 4 characters of both input field ($("#FNAME").val()) and grid column value (FNAME).
So, I can do on input field as follows...

enteredFilterStr = "FNAME~substringof~'" + $("#FNAME").val().substr(0,3) + "'";

But how can I apply the same logic on FNAME grid column value?

have you tried playing with the query string filter? 

http://server/index.html?Grid-filter= {insert filter}

No, I don't have any idea of this. Can you give details of the same. Just now I have following code...

gridPersons.filter("FNAME~substringof~'" + $("#FNAME").val() + "'and~MNAME~substringof~'" + $("#MNAME").val() + "'and~LNAME~substringof~'" + $("#LNAME").val() + "'");
$('#PersonSearchListWindow').data('tWindow').center().open();

where gridpersons variable having all records and applying filter on it gives filtered data.
and grid is then shown in PersonSearchListWindow  telerik window. So how can I apply your logic now?
