Editor show RTF Text

Hi,

is it possible to show Word RTF Text inside this editor (bcz when I do I get all the RTF Stuff printed out and not processed) ?

And if not, is there any way to display RTF Text inside one of your components ? (I tried the new component you added which converts html to rtf, but its not always converting my stream text correctly - I guess I am missusing that component by just trying to convert text, but I tried my luck :)

Regards

Paging: Only load data of the current page

Hi

Is it possible to implement paging in a way that the Datasource contains only the Data to display?

Lets assume i have 1 Million records, but for performance reasons i just want to load 10 at a time from sql server.

How can I tell the Grid that he's on Page 2 of X and have a total record of 1 Million (in AJAX mode)?

DECLARE @PageNumber AS INT, @RowspPage AS INT

SET @PageNumber = 2

SET @RowspPage = 10

SELECT ID_EXAMPLE, NM_EXAMPLE, DT_CREATE

FROM TB_EXAMPLE

ORDER BY ID_EXAMPLE

OFFSET ((@PageNumber - 1) * @RowspPage) ROWS

FETCH NEXT @RowspPage ROWS ONLY;

Thanks and best Regards

Giuseppe

Changing TabIndex for Grid Pager Elements

For adherence to compliance standards, I would like to provide the ability to focus the grid pager elements via the keyboard.

Given the following grid:

@(Html.Kendo().Grid<WebPortal.WebModels.Search.MemberReference>()

.Name("MemberGrid")

.HtmlAttributes(new { style = "height: 220px;" })

.Columns(columns =>

{

columns.Bound(m => m.FullName).Title("Member Name").Width(230)

.ClientTemplate("<a href='javascript:'

onclick=\"selectMember('#: ProperNameWithCityState#', '#: City#', '#: State#', '#: SystemId#', '" + Model.InputSystemId + "', '" + Model.InputFullName + "')\" >#= FullName#</

a>");

columns.Bound(m => m.HccId).Title("ID").Width(230);

columns.Bound(m => m.BirthDate).Title("Birth Date").Width(80);

columns.Bound(m => m.City).Title("City");

columns.Bound(m => m.State).Title("State").Width(60);

})

.Pageable(p => p.Messages(m => m.Empty(@noSearchResultsMessage)))

.Reorderable(reordable => reordable.Columns(true))

.Resizable(resize => resize.Columns(true))

.Sortable()

.Scrollable()

.Events(events => events.DataBound("onGridDataBound"))

.AutoBind(false) // Prevent initial data load

.DataSource(dataSource => dataSource

.Ajax()

.ServerOperation(false)

.Sort(s => s.Add("FullName"))

.PageSize(5)

.Read(read => read.Action("FindMembers", "Search")

.Data("getMemberSearchInput")

)

.Events(events => events.Error("onKendoDataSourceError").Change("onGridDataSourceChange"))

)

I am attempting to do this on the grid data bound event:

function onGridDataBound(e) {

// set tab index on pager elements so they can be focused via keyboard

$("#MemberGrid > div.k-pager-wrap.k-grid-pager.k-widget").find("a").not(".k-state-disabled").attr("tabindex", "0");

}

While I can verify that the jQuery selection is correct, the tab index does not seem to get persisted in the rendered code. The rendered pager elements still have a tab index of "-1".

Is there another event I should be using?

Grid in Wizard

Hi,

I'd like to add a grid in one of my steps but having a hard time figuring this out and no good examples. I'd like to load the content by calling my controller using the method ".LoadContentFrom("ActionName", "ControlerName");" which you have the ability to with many other controls but for now I think using a TemplateId will work?

Thanks,

Wizard
