Set grid footer format only if rows exist

Hi,

We've got a simple server bound grid which show aggregates in the footer and sets the Footer Template format to be currency - ...

.FooterTemplate(f => f.Sum.Format("{0:c}")).

Good if there are rows, but this throws an error if there are zero rows returned in the model.

How can we apply the correct formatting only if there are rows returned?

(Found this thread but the last response says the answer was through a support call - http://www.telerik.com/forums/conditionals-embedded-in-client-templates )

Many Thanks,

Dan.

Sorting in Grouped Column - Telerik Mvc Grid

I am trying to add sorting inside grouped columns, So the Grid is grouped by X and Y columns and then I need to sort for the rows in it.
I need to sort by CustomSortIntegerValue if CustomSort = true, and Alphabetically by Name if CustomSort = false. The last line does not work. Can you please give an pointers/examples on how to achieve this.

@(Html.Telerik().Grid(Model)
.Name("Grid")
.NoRecordsTemplate("Loading ..... Please Wait")
.Columns(c =>
{
c.Bound(x => x.Name).Title("Name");
c.Bound(x => x.CustomSortIntegerValue).Title("Custom Sort");
c.Bound(x => x.Id).ClientTemplate(Html.ActionLink("Edit", "Edit", new { id = "<#=Id#>" }).ToString()).Filterable(false).Sortable(false).Title("").Width(50);
})
.DataKeys(keys =>
{
keys.Add(x => x.Id);
})

.DataBinding(dataBinding => dataBinding.Ajax()
.OperationMode(GridOperationMode.Client)
.Select("RetrieveAllData_AjaxBinding", "CDController"))
.Groupable(grouping => grouping.Groups(groups =>
{
groups.Add(x => x.X);
groups.Add(x => x.Y);
}).Visible(false))
//.Sortable(sort => sort.OrderBy(sortOrder => sortOrder.Add(x => x.CustomSort ? "CustomSortIntegerValue" : "Name").Ascending()).Enabled(false))
)

Validation in Sitefinity fileupload form widget

Hi,

Not exactly sure if I'm in the right place, but here goes. I've included the default Sitefinity file upload widget into my form and have set it to be required. However, when I submit the form it doesn't validate whether a file has been selected or not. The unobtrusive validation is visible if you cancel when selecting a file but does not stop the form from being submitted.

Is this an error in the widget, of am I missing a different setting?

Kind regards,

Remove the Time rows in the Day view

My tasks are going to be all day tasks only. The All Day row has several tasks in it but they are bunched up. I need to remove the time rows in the Day view.

I've tried this as a databound event:

function scheduler_dataBound(e) {

var scheduler = this;

var ele = scheduler.wrapper.find(".k-scheduler-layout>tbody>tr:nth-child(2)");

ele.remove();

if (!isResizedManually) {

isResizedManually = true;

scheduler.view().refreshLayout();

$(window).trigger("resize");

} else {

isResizedManually = false;

}

This gets rid of the time rows but the all day row is still the same height. Another problem with this is that it removes the time rows for all views: Month, Week, Day, etc... I only want them removed for Day.

How can I get this to work?

DatePickerFor stopped working with latest update

I've been developing an app for some time now using the Kendo UI MVC wrappers. I just updated my Telerik components with version 2014.2.1008 this weekend. All of a sudden, the DatePickerFor is not working correctly for nullable DateTime values where it had been working before. Instead of a non-null date value being displayed, I see something like {0:17} in the edit box and it won't validate.

Assuming my model has a property like this:

     public DateTime? DueDate { get; set; }

The following .cshtml markup produces the erroneous result:

    @Html.Kendo().DatePickerFor(model => model.DueDate)

The following .cshtml markup produces the correct result, but I can't use it because the value may be null:

    @Html.Kendo().DatePickerFor(model => model.DueDate.Value)

I can't deploy other code I've been working on tonight because of this problem. I need a resolution to this ASAP.
