SetOptions and Toolbar

[Gusev]

Hello guys,

I need this functionality (https://demos.telerik.com/kendo-ui/grid/persist-state) but there are some problems.

I want to clarify one thing:
 - You have a grid (you may check your own link - https://demos.telerik.com/aspnet-mvc/grid/editing-popup)
 - In console I write:

var grid = $(".k-grid").data("kendoGrid");
grid.setOptions(grid.getOptions())"

and suddenly the toolbar breaks down.
  
I've checked a javascript version (https://demos.telerik.com/kendo-ui/grid/editing-popup) and everything is fine over there.

Let's check how "grid.options.toolbar" looks like:
JS:

{name: "create"}{name: "save"}{name: "cancel"}

MVC:

{ command: { { name: null, buttonType: "ImageAndText", text: "create"}, ...

So, it seems as "grid.options.toolbar" is useless when we talk about "MVC Wrappers".

The most important part - https://docs.telerik.com/kendo-ui/api/javascript/ui/grid#methods-setOptions
Yes, I see this note "When using the Grid MVC wrapper, any server templates will not be retrieved by the getOptions", but what can be counted as a "server template" talking about "toolbar"? If I use Kendo MVC, then everything or only when I use this one ".ToolBar(s => s.Template("<a random template>"))"?

So should I use what's described in this link?
https://github.com/telerik/ui-for-aspnet-mvc-examples/blob/master/grid/grid-preserve-server-toolbar-template-after-set-options/GridPerserveToolbarServerTemplate/Views/Home/Index.cshtml

Thank you for your time and sorry, probably I'm not the first who's asked it
Have a nice day

Hi,

Indeed when using a toolbar Template() it will not be persisted out of the box by getOptions. In that scenario it is recommended to use the approach illustrated in the example you are referring to. 

This is necessary as the server-side templates are rendered server side. When restoring them via setOptions the templates need to be reinitialized to be displated correctly.

Hi Viktor,

Can you please provide example for persisting default create toolbar generated using below code. How do I handle conditional part in this scenario.

.ToolBar(toolbar =>
      {
          if (condition)
          {
              toolbar.Create().Text(Resources.Constant_AddNewTemplate);
          }
      })

Hello Jigisha,

 

In order to implement the behavior you can add similar condition when restoring the Grid settings. You can access a field in JavaScript using the approach described in the stackoverflow thread below.

When this is available you can construct the Grid options object accordingly and call setOptions.
