Filtering numeric value with a custom dropdown

[Joshua]

Hi,

Right now, I'm struggling to implement a custom dropdown filter for a column which displays numerical data. The dropdown doesn't end up getting populated with any of the data from that column. I modified a dojo to demonstrate what I'm talking about. In this dojo, no data displays in the dropdown filter for "Freight". I'm struggling to figure out why this is not working.

Thanks for your help!

Hello Joshua,

The reason why the drop down is not populated is because args.dataSource is undefined. Even then this configuration is placed inside the columns.filterable.cell.template function, you can still define dataSource as when using a regular drop down configuration.

I modified the sample you sent to use the same data source as the grid and now works as expected:

Won't initializing a separate dataSource allow for duplicate values coming back for the dropdown? I thought that was the reason to use args.dataSource, so that there are no duplicates: http://docs.telerik.com/kendo-ui/api/javascript/ui/grid#configuration-columns.filterable.cell.template

Hello Joshua,

We discussed the behavior with the developers and it seems to be a bug. The same functionality works when the type of the column is string but it brakes when it is a number. Check out the following sample:

• http://dojo.telerik.com/aVUYe

  
We will investigate what is causing this behavior and fix it as soon as possible. As a token of gratitude for reporting the issue to us I have updated your Telerik points.

As a workaround until we fix the issue, you can configure custom data source and return distinct items from your service
