Hi,

Need help to find the best way to apply filter in links - or a different method if that's better.

This is what I want.
I have a page that shows a lot of names, and when clicking on a name, another page should appear showing details for that particular name.
My initial thought was, that this is done by filtering, right !!
Using filters, also allow the user to cancel the restrictions or change filter options, if desired.
I still think this is the right way, I just don't know how.

I have played around with action links:

...ClientTemplate(@Html.ActionLink("#=Company.Name#", MVC.Company.ActionNames.Index, MVC.Company.Name, new { id = "#=Company.Id#" }).ToHtmlString());

-which gives the following URL: "http://localhost:65398/Company/Index/12345".
It would then be possible to save this ID in a session variable and then load it when the AJAS request arrive and then apply the extra FilterDescription to the list of filters, but it's still a hack.

I guess I have to find a way to add the filter parameters to the URL so kendo grid recognize it as a filter.
Any help would be appreciated.
Thanks.

Custom Template DropDownList: Initial value not set on save

Hi,

I'm using the Kendo UI ASP.NET MVC Grid with a Custom Template which includes a DropDownList in a column. The data must be loaded based on different filters, so I populate the DropDownList via a DataSource.

Everything works fine, except if I do not change the value.
These are the steps:
* The grid is loaded, there is no option label, so the first entry is visible.
* If I change the value in the DropDownList, everything works fine and the value is sent to the Server
* If I do not change the value, I get null as value on the server.

It seems like the initial value is not sent back to the server.

What can I do about this? My Kendo Version is 2012.3.1114.

Greets

Attached my custom template in the grid:

@(Html.Kendo().DropDownListFor(m => m)

.Name("SalesRep")

.DataSource(

config => config.Read(read => read.Action("SalesRepRead", "TemplateData", new { area = "" }).Data("filterGrid")))

.DataValueField("Value")

.DataTextField("Text")

)

Problems with default Operator on Filter

Currently using version 2014.3.1411.

I am trying to always filter on the "contains" operator for string columns in my grid.

The problem is that when I start typing in any of the the filters, a request is sent to the
DataSource Read with the following data:

sort:page:1group:filter:Name~startswith~'t'

Then after a delay a second call is sent:

sort:page:1pageSize:5group:filter:Name~contains~'t'

The second call is correct. It has the correct pageSize and filter.

In the grid I have removed all filters except Contains and assigned an Operator("contains") to each filtered cell.

If I inspect the Filter i see this:

<input data-bind="value: value" data-role="autocomplete" data-text-field="Name" data-filter="startswith" data-delay="100" data-min-length="1" data-value-primitive="true" type="text" class="k-input" autocomplete="off" role="textbox" aria-haspopup="true" aria-disabled="false" aria-readonly="false" aria-autocomplete="list" aria-owns="" style="width: 100%;" aria-busy="false"><br>

This is the grid:

@helper RenderProductsSearch()

{

@(Html.Kendo().Grid<ViewableSelectableProduct>()

.Name("grid-products-search-#=ID#")

.AutoBind(true)

.Pageable(pager => pager

.Input(true)

.Numeric(true)

.Info(true)

.PreviousNext(true)

.Refresh(true)

.PageSizes(true)

)

.Scrollable()

.Sortable()

.Navigatable()

.Filterable(ftb => ftb.Mode(GridFilterMode.Row))

.HtmlAttributes(new { style = "height: 100%; border: 0;" })

.Columns(columns =>

{

columns.Bound(e => e.Name).Width(300).Title("name").Filterable(f => f.Cell(cell => cell.Operator("contains").ShowOperators(false).Delay(100)));

columns.Bound(e => e.Sku).Width(200).Title("sku").Filterable(f => f.Cell(cell => cell.Operator("contains").ShowOperators(false).Delay(100)));

columns.Bound(e => e.ShortDescription).Title("description").Filterable(f => f.Cell(cell => cell.Operator("contains").ShowOperators(false).Delay(100)));

columns.Command(command => command.Custom("Select").Click("selectProduct"))

.Title("commands")

.Width(Constants.Columns.Default.Widths.ColumnCommands);

})

.Filterable(filterable => filterable

.Extra(false)

.Operators(ops => ops

.ForString(str => str.Clear()

.Contains("Contains")

)))

.DataSource(dataSource => dataSource

.Ajax()

.Model(model =>

{

model.Id(p => p.Id);

model.Field(x => x.Id).Editable(false);

model.Field(x => x.Name).Editable(false);

model.Field(x => x.Sku).Editable(false);

model.Field(x => x.ShortDescription).Editable(false);

})

.PageSize(5)

.Events(events =>

{

events.Error("standard_grid_error_handler");

})

//.Batch(true)

.ServerOperation(true)

.Read(read => read.Action("ReadSelectable", "Product", new { blockId = "#=ID#" }))

)

.ToClientTemplate()

)

}

Why is the first call happening and why does the input data-filter contain the wrong operator?

thanks

Values are disappearing at in-Cell editing

Hi there,

I've created a grid which bounds on a "Special" object, which has "real" properties and a list of variable properties.

This is the (single) object:

public class DynPartView

{

Guid _Id;

public Guid Id

{

get { return _Id; }

set { _Id = value; }

}

List<Prop> _Properties;

public List<Prop> Properties

{

get { return _Properties; }

set { _Properties = value; }

}

...snip...

string _Standard;

public string Standard

{

get { return _Standard; }

set { _Standard = value; }

}

string _SelectedMKL;

public string SelectedMKL

{

get { return _SelectedMKL; }

set { _SelectedMKL = value; }

}

string _SelectedManufacturer;

public string SelectedManufacturer

{

get { return _SelectedManufacturer; }

set { _SelectedManufacturer = value; }

}

And this is the view:

@(Html.Kendo().Grid(Model)

.Name("partgrid")

.DataSource(dataSource => dataSource

.Ajax()

.Batch(true)

.ServerOperation(false)

.Model(m =>

{

int y;

m.Id(d=>d.Id);

m.Field(f => f.SelectedMKL);

m.Field(f => f.SelectedManufacturer);

m.Field(f => f.Standard).Editable(false);

for (y = 0; y <= Model.PropertiesCount; y++)

m.Field(f => f.Properties[y].Value);

})

.Read(read => read.Action("Read_DynParts", "Parts", new { typeID = _typeid, mklName = _name }))

.Create(create => create.Action("EditingInline_Create", "Parts"))

.Update(update => update.Action("EditingInline_Update", "Parts"))

)

.ToolBar(toolbar =>

{

toolbar.Create();

toolbar.Custom().Text("Kopieren");

toolbar.Save();

})

.Columns(columns =>

{

int j = 0;

columns.Bound(b => b.Id).Hidden();

columns.Bound(b => b.SelectedMKL).Title("MKL");

columns.Bound(b => b.Standard).Title("Norm");

columns.Bound(b => b.SelectedManufacturer).Title("Hersteller");

for (j = 0; j < Model.PropertiesCount; j++)

{

string _title="";

if (Model.Count() >= 1)

_title = Model[0].Properties[j].Name;

columns.Bound(b => b.Properties[j].Value).Title(_title);

}

})

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

.Editable(editable => editable.Mode(GridEditMode.InCell))

.Filterable(ftb => ftb.Mode(GridFilterMode.Menu))

.Pageable(page => page.Enabled(true).PageSizes(new int[] { 10, 30, 50, 100, 1000 }))

.Sortable()

.Selectable(sel => sel.Mode(GridSelectionMode.Single))

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

)

The issue I have: If I click on a property, which is stored in Properties the value is disappearing in the editbox. If I click on a property, which is a "direct" member of the class (e.g. "SelectedMKL"), the value is correctly shown after clicking the cell.
See the Pictures attached.

How can I prevent the value from disappearing?

Greetings, Denis

I have columns Teach%, Sch%, Cit%. My end column is Total%. My client does not want to add up the number manually and enter it as data. They want a row by row total of Teach%, Sch%,CIt% to be summed up in calculated Field Total%.

How can this be accomplished?

Thank you.

Turn off automatic daylight savings detection

Hi,

I noticed when running some tests based on Daylight Savings, that any attempt to select a time during the Spring transition results in the time being set back an hour. (To see this behaviour, attempt to enter 2:30 AM on March 8, 2015). However there are many places that do not recognize Daylight Savings even in time zones that generally do, so I was wondering if there was a way to disable this feature?

Thanks,
Kevin

.Mobile(MobileMode.Phone)

When i use .Mobile(MobileMode.Phone) to get the "add scheduler entry" box to open on tablet / iPhone with one press, this work fine.

However, This same option then opens strangely on the desktop, full width. I would like the desktop to open a popup window, as it would normally do if the additional .Mobile(MobileMode.Phone) was not added. The site is a responsive site and needs this functionality.

Thank you in advance...
