[Solved] Grid Filtering Issue - Enums in Client OperationMode

[Ron DeFreitas]

I'm not sure if you guys have this fixed in the Commercial license, but I noticed this issue and found the fix for it in version 2011.2.712.  My apologies if this is the wrong forum or if this was already answered, but since I couldn't find it myself I had to go digging.

Problem:
Only tested this in Firefox, but attempting to filter on a numeric Enum column while in Client OperationMode would fail to change the grid, and would yield the following error in Firebug:

aE.toLowerCase is not a Function

Source:
I located the issue in telerik.common.js - line 1743

if(typeof expr.value === "string" && !expr.caseSensitive) {

     caseSensitive = function(value) {

        return value.toLowerCase();

     };

Solution:
The assumption was made that the filtered value was a string in all cases.  Cast it to a string and move on with your life :)

if(typeof expr.value === "string" && !expr.caseSensitive) {
     caseSensitive = function(value) {
        return value.toString().toLowerCase();
     };

Attachments:
I've attached a new version of telerik.common.min.js for users of version 2011.2.712 that resolves this issue.

[Edit - The previous version I attached still had an extra debugger... this one should be fine]

Hmmm, frustrating that you cannot remove posted files on this forum...

Here is the correct attachment.

Hi Ron Defreitas,

Thank you for reporting this. We were able to locate the problem. The fix will be available with next version of the component. Meanwhile I have updated your telerik points.

Thanks Rosen,

Here is the complete snippet I ended up fixing, as failing to cast the other value to a string was causing a different error...  (again, starting from line 1743)

if(typeof expr.value === "string" && !expr.caseSensitive) {
     caseSensitive = function(value) {
        return value.toString().toLowerCase();
     };
} else {
    caseSensitive = function(value) {
        return value.toString();
    };
}

I also did get error on same lines, but my error was value is null error. This happened when i was grouping in mvc grid on a column which also had null values. So did change those lines with null check. I am not really good at javascript, but it works onmy mahine

if(typeof expr.value === "string" && !expr.caseSensitive) {
     caseSensitive = function(value) {
        return  value == null ? "" : value.toString().toLowerCase();
     };
} else {
    caseSensitive = function(value) {
        return value == null ? "" : value.toString();
    };
}
