Create unique name for grid in template

[Ludek Soukup]

Hi,
I need to create unique grid name inside template, i try with javascript, but it doesn't work.

<script id="conditionGroupTemplate" type="text/x-kendo-template">
    @(Html.Kendo().Grid<Rule.ConditionViewModel>()
                  .Name("entryGroupConditions" + //here i need to call getGUID()//)
                  .Columns(columns =>
                  {
                      columns.Bound(o => o.Text);
                      columns.Command(command =>
                      {
                          command.Destroy();
                      }).Width(110);
                  })
                  .ToolBar(toolbar =>
                  {
                      toolbar.Template("<div class='toolbar'><a class='k-button k-button-icontext pull-left' onClick='AddGroup(\"\\#entryGroupConditions\", \"Skupina podmínek\")'><span class='k-icon k-add'></span>Přidat skupinu</a><h3>AND</h3></div>");
                  })
                  .ClientDetailTemplateId("conditionTemplate")
                  .AutoBind(false)
                  .DataSource(ds => ds
                      .Ajax()
                      .Model(m => m.Id(o => o.Path))
                      .Destroy(del => del.Action("DeleteAttribute", "Rule"))
                  )
                  .Resizable(resize => resize.Columns(true))
                  .ToClientTemplate()
    )
</script>

function getGUID(){
        return (salt() + salt() + "-" + salt() + "-4" + salt().substr(0,3) + "-" + salt() + "-" + salt() + salt() + salt()).toLowerCase();
    }

    function salt(){
        return (((1+Math.random())*0x10000)|0).toString(16).substring(1);
    }

Any help?
thanks

Hi Ludek,

The Name string of the Grid can contain a Kendo UI template expression, for example:

http://demos.telerik.com/aspnet-mvc/grid/hierarchy

.Name("grid_#=EmployeeID#")

... where EmployeeID is the unique primary key field in the master Grid.

One may expect to be able to use something like this:

.Name("entryGroupConditions#=getGUID()#")

http://docs.telerik.com/kendo-ui/framework/templates/overview#handle-external-templates-and-expressions

However, this approach cannot be used for widget names, due to special escaping that occurs behind the scenes.

That's why the expression inside the Grid Name() can only contain a variable reference, and no function calls or arithmetic operators. The variable can be either a custom global variable from the page, or a field from the master Grid's data item.
