Description

hi, i want to add some custom field in columnDefs and want to access it from header template. As an example , i want a field let say showFile

$scope.gridOptions.columnDefs = [

       {                
                name: 'ServiceID',
                displayName: 'Service',
                showFile: some data
      }

and want to access showFile inside header template ...


<div class="ui-grid-top-panel"  style="text-align: center">
      {{ want to access 'showFile' }}
</div>

What's the best possible way to do this. As i have tried it using custom method as

<div class="ui-grid-top-panel"  style="text-align: center">
{{grid.appScope.letter()}}
</div>

(plnkr link http://plnkr.co/edit/ZW43LsiLY7GdnX6XEOgG?p=preview ) but , the function (grid.appScope.letter()) is being called for infinite number of times . I have raised the issue but didn't got any reply .. https://github.com/angular-ui/ui-grid/issues/4250 . Can anyone please suggest the best possible way to achieve the above mentioned task.

Research direction
Investigate the ui grid source code to understand how columnDefs are processed and how header templates are compiled. Review the linked issue #4250 for similar context. The custom field 'showFile' needs to be exposed in the header template scope. Check the grid API for methods to access column properties in templates.
