[Solved] Hiding plus sign in detail view

[Venkitachalam]

Hi,

I am using server side hierarchy for detail view of grid.
Is it possible to hide ‘+’ sign if child list (details) is null?

Thanks & Regards,

Hi Venkitachalam,

In order to hide the expansion button under conditions, try to add property on your record (like ChildsCount), and use onRowDataBound to change innerHtml of td that contains expansion link.

@(Html.Telerik().Grid<ParentModele>(Model.Data)
.Name("parents-grid")
.Columns(columns =>
{
columns.Bound(x => x.Id)
.ClientTemplate("<#= Id #>")
.Title("Id");
})
.DetailView(ssSsdetailView => ssSsdetailView.ClientTemplate(
Html.Telerik().Grid<ChildsModele>()
.Name("Childs_<#= Id #>")
.Columns(columns =>
{
columns.Bound(x => x.Id)
.Title("Id");
columns.Bound(x => x.Title)
.Title("Title");
})
.DataBinding(dataBinding => dataBinding.Ajax().Select("Liste", "Childs", new { idParent = "<#= Id #>" }))
.Pageable(settings => settings.PageSize(25).Position(GridPagerPosition.Both))
.ToHtmlString()))
.Pageable()
.DataBinding(dataBinding => dataBinding.Ajax().Select("List", "Parents"))
.EnableCustomBinding(true)
.ClientEvents(events => events.OnRowDataBound("onRowDataBound")))

<script type="text/javascript">
function onRowDataBound(e) {
if (!e.dataItem.ChildsCount)
e.row.cells[0].innerHTML = '';
}
</script>

You just have to set property Childscount of your ParentModele objects.
