Hi,

The much anticipated excel like filter capability is scheduled to be release on Q1 2015. Also we know that kendo grids can support persisting it's state (including filters) via grid.options.

My question is whether the excel like filters be capable of reloading their filter status (i.e all checkboxes matching a grid filter are checked) by default, if we follow the normal save/persist techniques as outlined here.

Thanks a lot.
Chris.

Specifying a template when using BindTo

Is it possible to specify a template when using BindTo? I tried the following:

@(

Html.Kendo().TreeView()

.Name("treeView")

.BindTo(Model, mapping =>

mapping.For<SomeViewModel>(binding =>

binding.ItemDataBound((item, viewModel) =>

{

item.Text = viewModel.DisplayName;

})

.Children(viewModel => viewModel.Children)))

.TemplateId("some-template")

)

Specifying the template like that has no impact on the node at all. I also noticed in ItemDataBound the NavigationItem (item) has a Template property but I'm not sure what to set on it (nothing I tried worked). I also tried the Html property, but that messes up the bindings. How can I define a template?

How Hide a Column?

In KendoGrid you have for example Hidden():

@(Html.Kendo().Grid<MyModel>()
.Name("cdhReservaGrid")
.HtmlAttributes(new {@class="slim-rows"})
.Columns(columns =>
{
columns.Bound("IdReserva").Hidden();
})

How do you do this in Kendo TreeList??

Change FilterDescriptor.Member name in the view

Hi,

How to change the FilterDescriptor.member name in the view ?

columns.Bound(e => e.Name).Filterable(true);

In the above sample, the filter will set the Member to "Name", because this is the name of the property bound to the column.
What if I want to change the member name, is that possible ??
Thanks.

Custom Popup Editor for Individual Cell

Hi, I'm just getting started using UI for ASP.NET MVC and love the default popup editor. I was wondering how to create a popup editor that only shows editable data for one individual cell. Right now I have cells in a column that represent a grid of 3x3 numerical values and need the ability to edit these en masse. Right now I can edit my rows easily using inline, but this column and a few others display a List<type> of items that I have to write html elements for in javascript.

.Columns(columns =>

{

columns.Bound(p => p.LEXId).Hidden(true);

columns.Bound(p => p.LEXName).Title("Name");

columns.Bound(p => p.LEXDescription).Title("Description");

columns.Bound(p => p.AllTranches).ClientTemplate("#= tranchesTemplate(data) #"); //edit these cells in a popup

columns.Bound(p => p.ComponentName1).Title("Comp1");

columns.Bound(p => p.ProximityTranche1).Title("Proximity");

columns.Bound(p => p.ComponentName2).Title("Comp2");

columns.Bound(p => p.ProximityTranche2).Title("Proximity");

columns.Bound(p => p.IsActive);

columns.Command(cmd => cmd.Edit()).Title("Update");

})

<script type="text/javascript">

function tranchesTemplate(item) {

var html = "<table>";

for (var i = 0; i < item.AllTranches.length; i++) {

if (item.AllTranches[i]) {

if ((i % 3 == 0) || (i == 0)) {

html += "<tr>";

html += "<td>";

html += item.AllTranches[i];

html += "</td>";

} else {

html += "<td>";

html += item.AllTranches[i];

html += "</td>";

}

html += "</tr>";

html += "</table>";

html += "<table>";

html += "<tr>";

html += "<td><a class=k-button tranche-edit>Edit</a></td>";

html += "</tr>";

html += "</table>";

return html;

}

</script>

So I have all the tranches populated with the appropriate values, is there some way to quickly build out a popup 3x3 grid using jQuery? Apologies in advanced if this is answered somewhere, but my team lead is urging me to post on here. :)

MVC kendo Gird page Vulnerability

Hi,
I am try to looking for the solution to fix kendo Grid's vulnerability, the vulnerability had find by WebInpsect vulnerability scanner.
when the scanner send a attack post parameter like:

sort=%0d%0aSPIHeader:%20SPIValue&page=1&pageSize=6&group=&filter=&AreaId=-1&DisciplineId=-1&FieldId=-1&MajorId=-1&Keyword=

the scanner attack sort parameter, I got a error "DbSortClause expressions must have a type that is order comparable.", that seems sort parameter value problem, but I never assign sort parameter,

another problem is the scanner send another attach paramter "sort=&page=1%0d%0aSPIHeader:%20SPIValue&pageSize=6&group=&filter=&AreaId=-1&DisciplineId=-1&FieldId=-1&MajorId=-1&Keyword="
I got a exception
System.Number.StringToNumber(String str, NumberStyles options, NumberBuffer& number, NumberFormatInfo info, Boolean parseDecimal) +14345541

It's seems another Poor Error Handling issue in kendo grid.

Can any one give me some suggestion to fix those problems ?

Thanks, Regards,

TreeView: checkChildren property not to uncheck Parent when child unchecked

We are using kendo treeview to display hierarchial datasource in cshtml.

One of our requirement is to check/uncheck all children checkboxes when a parent is checked/unchecked, so we used checkChildren property to
achieve this.

@(Html.Kendo().TreeView()

.Name("SampleList")

.Checkboxes(chk => { chk.CheckChildren(true); })

.DragAndDrop(false)

.ExpandAll(true)

.....

But the issue is when we uncheck a child, the parent should not get unchecked, even if we have one child inside the parent.

Can you please provide jquery code snippet to achieve this?

Thanks.

Unknown params when using column filterable

Hi,

Working with MVC5 and Kendo().Grid.
Using filter on columns, won't fire the javascript function with the right params or I don't understand how to !!
The aim is to remove the decimals from the integer in the filter box.

This is what I have:

.Columns(columns =>

{

columns.Bound(e => e.InternalId).Width(60).Filterable(filter => filter.UI("NumericFilter()"));

})

-and the function:

function NumericFilter(control) {

alert ("Got here...");

$(control).kendoNumericTextBox({ "format": "n0", "decimals": 0 });

}

When the function is called, the param is null. If removing the parentheses from the function name in the filter definitions, the call is not fired at all.
The above code is found somewhere else on this site.
Thanks.
