newbie best practice for scripts

You've all been doing this for a bit, so please be patient...

Please follow along to see the logic…don't assume the initial error is my issue...

In MVC - I have a part view and wanted a datepicker on it.

So in my _PartialFormName.cshtml I had (from the sample) the following:

<input id="datepicker" />
        <script>
            $(function() {
                $("#datepicker").kendoDatePicker();
            });
</script>

This reports the error $ not defined.

That's because the render scripts call hasn't loaded the JQuery library at the bottom of the _Layout.cshtml page:

    @Scripts.Render("~/bundles/scripts")

AND the script is not in a @section Script section that will be rendered by the call:

    @RenderSection("scripts", required: false)

So, I put the script for datetimepicker it in the @section Script block...

BUT that's in the main MainPage.cshtml razor page, NOT the _PartialFormName.cshtml partial page…

So I need to know and collect all the control scripts of ALL partial views and put their scripts in the containing page?

******************************************
Now the best practice question...

Should I reference a child script named for that partial view containing all of the kendo scritps for that page?

How do we best contain kendo scripts? Is there a best practice?

Thanks

Thanks

Clear grid ClientFooterTemplate

Hello,

I currently have a clear grid button and the following code clears the rows from the grid:

$("#studentGrid").data('kendoGrid').dataSource.data([]);

But my problem is, I have a ClientFooterTemplate with totals. How do I clear the ClientFooterTemplate in a javascript call? I could do it on the DataBound event, but just don't know how to clear that footer.

Thanks...

Kendo Grid - Data Annotations Validations

I am working on a UI where I am editing grid in an Ajax Popup Edit. The following data annotations do not work as expected in the popup edit:

[DataType(DataType.Password)]
[Display(Name = "Confirm password")]
[Compare("Password", ErrorMessage = "The password and confirmation password do not match.")]
public string ConfirmPassword { get; set; }

[StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 6)]
[DataType(DataType.Password)]
[Display(Name = "Password")]
public string Password { get; set; }

[StringLength(500, ErrorMessage = "Image path cannot be more than 500 characters.")]
[Display(Name = "Image path")]
[DataType(DataType.ImageUrl)]
[RegularExpression(@"^http(s?)\:\/\/[0-9a-zA-Z]([-.\w]*[0-9a-zA-Z])*(:(0-9)*)*(\/?)([a-zA-Z0-9\-\.\?\,\'\/\\\+&%\$#_]*)?$", ErrorMessage = "Image path format is incorrect.")]
public string ImagePath { get; set; }

Currently for Add/Edit both, I am getting a minimum password length should be 6. Also both for Add and Edit I get "Image path format is incorrect" even when there is nothing typed in that field

In addition to the above
On Edit - I do not want the password to be required. On New I want password to be required.

Thanks

Telerik Grid Custom Binding:Grouping on Complex Property

i have implemented Custom Binding.I get error like "object reference not set to an instance of an object" when Group a column which is complex Type(Order.Name).

public static IEnumerable<AggregateFunctionsGroup> BuildInnerGroup<T, TObject>(IEnumerable<TObject> group, Func<TObject, T> groupSelector, Func<IEnumerable<TObject>, IEnumerable> innerSelector)
{
return group.GroupBy(groupSelector)
.Select(i => new AggregateFunctionsGroup
{
Key = i.Key,
Items = innerSelector(i)
});
}

public static Func<IEnumerable<TObject>, IEnumerable<AggregateFunctionsGroup>> BuildGroup<T, TObject>(Func<TObject, T> groupSelector, Func<IEnumerable<TObject>, IEnumerable<AggregateFunctionsGroup>> selectorBuilder)
{
var tempSelector = selectorBuilder;
return g => g.GroupBy(groupSelector)
.Select(c => new AggregateFunctionsGroup
{
Key = c.Key,
HasSubgroups = true,
Items = tempSelector.Invoke(c).ToList()
});
}

public static IEnumerable<AggregateFunctionsGroup> ApplyGrouping<T>(this IQueryable<T> data, IList<GroupDescriptor> groupDescriptors)
{
Func<IEnumerable<T>, IEnumerable<AggregateFunctionsGroup>> selector = null;
foreach(var descriptor in groupDescriptors.Reverse())
{
var tempDescriptor = descriptor;
if(selector == null)
selector = g => BuildInnerGroup(g.Select(p => p), p => p.GetType().GetProperty(tempDescriptor.Member).GetValue(p, null), i => i.ToList());
else
selector = BuildGroup(p => p.GetType().GetProperty(tempDescriptor.Member).GetValue(p, null), selector);
}

return selector != null
? selector.Invoke(data).ToList()
: null;
}

For simple field it is working well.When I Group a field with complex type(Order.Name) i get the above error in ApplyGrouping function.In debug mode i see in ApplyGrouping function,the tempDescriptor.Member property value is Order.Name.I need to Split the property on dot(.) and make the grouping(like in the sorting which i already implemented for complex type). Please give a suggestion for grouping.i post the same issue in StackOverflow

Delete Record on Confirm popup

Hi guys, I have this grid:

@(Html.Kendo().Grid<Entity>(Model)

.Name("valueGrid")

.ToolBar(commands => commands.Create().Text("Add new value"))

.Columns(columns =>

{

columns.Bound(c => c.DOMAINID).Visible(false);

columns.Bound(c => c.CODE);

columns.Bound(c => c.VALUE);

columns.Command(command => { command.Edit().UpdateText("Save"); command.Destroy().Text("Delete"); });

})

//.Events(e => e.SaveChanges("OnSaveChanges"))

.Sortable()

.Scrollable()

.DataSource(dataSource => dataSource

.Ajax()

//.Events(e => e.Error("OnDatasourceError"))

.ServerOperation(false)

.Model(m => m.Id(v => v.CODE))

.Update(update => update.Action("UpdateValue", "DomainValue"))

.Create(create => create.Action("CreateValue", "DomainValue"))

.Destroy(delete => delete.Action("DeleteValue", "DomainValue"))

)

and I noticed that the delete action is called as soon as the user click on remove command, even if the confirmation popup is displayed.
I need to invoke the action only on the confirm from the user. I search a bit online but everyone is doing this with a custom popup.
I remember, however, that in another project I've done that automatically, but I wasn't using MVC back there.

Thanks
Fabio
