[Solved] Filter from clientside issues?

[Jang-Soo Lee]

I'm using an evaluation version of 2009.2.701.35, and seem to be running into issues filtering from the clientside. Whenever I try to call the filter function on the mastertableview, it gives me an error within the MicrosoftAjax.js served by TelerikWeb.UI.WebResource.axd, specifically that the trim() function is not available on a variable i. This error is within the Sys$Enum$parse function of that file.

The way that I'm calling the function that I'm calling is as thus (from a RadComboBox):

        function filterCounty(sender, args){

            $find(<%=RadGrid1.ClientID%>).get_masterTableView().filter("CountyCode", sender.get_value(), Telerik.Web.UI.GridFilterFunction.EqualTo);

//            alert(sender.get_value());

        }

Based on what I'm seeing, the enum gets evaluated to the numeric value 5, and then is sent to the Sys$Enum$parse function. For whatever reason, the javascript engine seems to choke at this point.

Is this a problem that has been run into before?

Just as added information, the call seems to originate from toDynamicLinq:function(b). This is what is given to my browser:

toDynamicLinq:function(b){var h="";

if(typeof(b)!="undefined"){h=b

}var i="";

if(this._filterFunction!=null){var g=Telerik.Web.UI.GridFilterFunctionsDynamicLinqFormat();

var f=g[Telerik.Web.UI.GridFilterFunction.parse(this._filterFunction)];

if(f!=null){var a=Telerik.Web.UI.GridFilterFunction.parse(this._filterFunction);

var e="";

var d="";

if(a==Telerik.Web.UI.GridFilterFunction.IsNull||a==Telerik.Web.UI.GridFilterFunction.NotIsNull){e=""

}else{if(a==Telerik.Web.UI.GridFilterFunction.Between||a==Telerik.Web.UI.GridFilterFunction.NotBetween){d=this.getDynamicLinqValue(this._fieldValue.split("")[1]);

e=this.getDynamicLinqValue(this._fieldValue.split(" ")[0])

}else{e=this.getDynamicLinqValue(this._fieldValue)

}}var c=this._fieldName;

if(h!=""){c=String.format("{0}.{1}",h,c)

}i=String.format(f,c,e,d)

}}return i

}

The line that calls the Sys$Enum$parse function is the below line. _filterFunction corresponds to 5: 

var f=g[Telerik.Web.UI.GridFilterFunction.parse(this._filterFunction)]; 

When I try with a string filtertype, instead of Linq, it also errors at the parse function, but from a different source:

toString:function(b){var h="";

if(typeof(b)!="undefined"){h=b

}var d=this._fieldName;

if(h!=""){d=String.format("{0}.{1}",h,d)

}var i="";

if(this._filterFunction!=null){var g=Telerik.Web.UI.GridFilterFunctionsSqlFormat();

var f=g[Telerik.Web.UI.GridFilterFunction.parse(this._filterFunction)];

if(f!=null){var a=Telerik.Web.UI.GridFilterFunction.parse(this._filterFunction);

if(a!=Telerik.Web.UI.GridFilterFunction.Between&&a!=Telerik.Web.UI.GridFilterFunction.NotBetween){if((this.get_dataTypeName()=="System.String"||this.get_dataTypeName()=="System.Char")&&a==Telerik.Web.UI.GridFilterFunction.Contains||a==Telerik.Web.UI.GridFilterFunction.DoesNotContain||a==Telerik.Web.UI.GridFilterFunction.StartsWith||a==Telerik.Web.UI.GridFilterFunction.EndsWith){i=String.format(f,d,this._fieldValue)

}else{i=String.format(f,d,this.getQuotedValue(this._fieldValue))

}}else{var e=this._fieldValue.split(" ")[0];

var c=(this._fieldValue.split(" ").length>0)?this._fieldValue.split(" ")[1]:"";

i=String.format(f,d,this.getQuotedValue(e),this.getQuotedValue(c))

}}}return i

}

It happens at the below line:

var f=g[Telerik.Web.UI.GridFilterFunction.parse(this._filterFunction)];

Just as a note: The documentation for the filter function found here: http://www.telerik.com/help/aspnet-ajax/grid_filter.html seems to be wrong. This is what caused the error.

Currently, the documentation says to use the enum (e.g. Telerik.Web.UI.GridFilterFunction.EqualTo), whereas the actual client-side filter function being used by the default RADGrid behavior uses a string ("EqualTo")

Thus, changing from:

$find(<%=RadGrid1.ClientID%>).get_masterTableView().filter("CountyCode", sender.get_value(), Telerik.Web.UI.GridFilterFunction.EqualTo);

to:

$find(<%=RadGrid1.ClientID%>).get_masterTableView().filter("CountyCode", sender.get_value(), "EqualTo");

made the script behave properly.

Please confirm and correct the documentation.

Thanks,

Hello Jang-Soo Lee,

I cannot reproduce the problem you described as both ways seem to work on my end. Find attached a simple example which behaves as expected with the latest version of the controls. Try it out and let us know what is different in your scenario.

I faced the same problem above, and the string filter type "Contains" instead of 1 solved the problem !!! thanks Jang-Soo Lee
