I have a GridTemplateColumn that displays 3 columns of data - Parent/Child relationship with the current row. I need to be able to filter on any of the three columns.
I can create a FilterTemplate that displays 3 textboxes in the FilterCell to match up with the 3 columns of data. But I can't get the GridFilterMenu to attach to the textboxes. The example for the MS DropDownlist customization is sort of what I'm trying to do (http://www.telerik.com/help/aspnet-ajax/grdoperationswithdropdownlistinedititemtemplate.html). But that is based on a single column of data.
Any ideas of how I can expand this to incorporate all the textboxes in the filter template?
Thanks

Hello Phil,
Basically, to be able to filter a template/custom column you have to set its DataField property. Since this value accepts a single field, filtering by more than one field from the same template column is not supported scenario.
As a workaround you can add separate columns for the different fields, but hide those of them that you do not need. This way you can apply the approach demonstrated in this online example and add additional controls in the filter template of the template column. I have attached a small sample that implements this technique. For demonstration purposes I have left the "City" column visible, but if you do not need it in the grid columns, just hide it by setting Display="false".
I hope this helps.
