HI

I met a problem about Grid Sortable : 

  Grid setOptions sortable = false clear header template UNEXPECTEDLY.

What's going on ?? Why header template lost ? 
How to avoid this situation or 
how to disable sortable temporary and header template will not be cleared.

Sample Code : 


  View
                columns.Bound(c => c.Column1)
                  .HeaderTemplate
                  (
                    @<text>
                
                    <input type='number' class='k-textbox' onfocus="class1.focusAllDays({ element: this })" style='width: 50px; font-size: small;' />

                    </text>
                  )
                  .Width(280);


  Javascript

    class1 : 

    focusAllDays: function(e)
    {
      var grid = get your grid;
      //
      grid.setOptions({  sortable: false });
    },


Best regards

Chris

Hello, Chris,

The issue occurs because the header template is rendered on the server and after the setOptions method is used the template is lost on the client.

We have an example how this can be resolved for the Toolbar template, but the logic is similar for the header:

https://docs.telerik.com/aspnet-mvc/helpers/grid/how-to/state/grid-preserve-server-toolbar-template-after-set-options

I hope this is helpful.

Regards,
Stefan
