Kendo Grid Header - column context menu replaces default "sort" when clicking Header text

I have a Kendo grid with sorting, filtering and column menu enabled. Out of the box, there are two clickable actions in each column header:
* Clicking the title in the column header sorts the data in that column
* Clicking the chevron column menu icon displays the column menu options

What I’d like to accomplish - instead of a sort being applied when the title in the column header is clicked is for the column menu options (sort asc, sort desc, columns, filter) to appear. Essentially, I want the title in each column header to take the place of the chevron icon. Is this possible? The main motivation is that some of the columns are just too narrow (ex: 40px)to properly display all the default icons. Is there some event that can be intercepted to do this? BTW, I am using the MVC Html wrappers to setup the grid - if that matters.

Thanks,
R Cornish

Preserve grid state in a cookie - Razor syntax

Hi, i am trying to follow this guide and rewrite it to the Razor syntax:
Preserve grid state in cookie example.

The difference from my code and the example code is that they use AutoBind: false.
I cant use that in Razor because i initialize the data into the model when the view is rendered.

Another difference is that the example uses schema: syntax, don't think i need that when using razor, Am i correct?

Here is my razor code:

01.@model IEnumerable<Backend.ViewModel.ViewSalon>

02.<div id="salonDetail">

03.

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

05. .Name("Grid")

06. .Columns(c =>

07. {

08. c.Bound(m => m.Id).Width(30);

09. c.Bound(m => m.Name).Width(110).HtmlAttributes(new { @class = "customerName" });

10. c.Bound(m => m.Telephone).Width(100);

11. c.Bound(m => m.ContactPerson).Width(100);

12. c.Bound(m => m.City).Width(50);

13. c.Bound(m => m.StatusId).HtmlAttributes(new { @class = "statusid" }).Hidden();

14. c.Bound(m => m.Kundnr).Width(50);

15.

16. })

17. .Scrollable()

MultiSelectFor and Values

Here is a code snip:

@Html.Kendo().MultiSelectFor(model => model.Programs).BindTo((SelectList)ViewBag.Programs).DataTextField("Text").DataValueField("Id").Name("SelectedProgramIds ")

ViewBag.Programs is populated by:

Models.Program[] obj = model.List();

ViewBag.Programs = new SelectList(obj, "Id", "Name", project.Programs);

I'm also using:

public IEnumerable<String> SelectedProgramIds { get; set; }

.. as the property for the saved value in the model.

After I POST, SelectedProgramIds contains the Text Name (but not values) of the entries in the MultiSelect control. How can I get the Value as set by DataValueField(), instead of the DataTextField() after POST?

Also, when the control loads, how can existing items be selected? Currently the box is empty.

$("#regMachine").hide();

</script>

what I want to implement now is something like this:
after the sumbit(save, update) button is clicked I don't want the window to close. I want it to remain open and display something like a progressbar or an ajax loader to inform the user that sth. is happening right now and there's no need to submit again.

in the background there will be items added to the database and I want to display the amount of items added on a new view.

when the db operation is finished the loader should disappear and something like: 6 items have been added to the database should be displayed on a lets call it success view.

hopefully there's a way without creating kendo windows, having partial views with the content displayed and an ajax.beginform.

thanks in advance
cheers, tom

RadHtmlChart TooltipsAppearance ClientTemplate does not display data on binding to a value from database.

Hi,
Facing an issue while binding tooltip to database item, below is the code for reference -

<Series>
<telerik:ColumnSeries Name="Power" Stacked="true" DataFieldY="TotalPower" AxisName="Power">
<Appearance>
<FillStyle BackgroundColor="#36b8f4"></FillStyle>
</Appearance>
<LabelsAppearance Position="Center" Visible="false">
</LabelsAppearance>
<TooltipsAppearance ClientTemplate="#= dataItem.TotalPower#">
</TooltipsAppearance>

<%--
<TooltipsAppearance ClientTemplate="#= kendo(\'{0:dd MMM yy}\', dataItem.Date)#<br/>Power: #= kendo.format(\'{0:N2}\',dataItem.TotalPower)# kW">
</TooltipsAppearance>
--%>
<%--
<TooltipsAppearance ClientTemplate="#=dataItem.Date#<br/>Power: #=dataItem.TotalPower# kW">
</TooltipsAppearance>--%>

</telerik:ColumnSeries>
</Series>

When i use ClientTemplate in TooltipsAppearance to bind tooltip to TotalPower value (this value comes from dataset), it shows "undefined" on mouse over, and instead of ClientTemplate if dataformatstring is used then it display the value
(<TooltipsAppearance DataFormatString="{0}"></TooltipsAppearance>).

My requirement is that, i want to display both Date and TotalPower values in tooltip. Also, tried using kendo after googling this issue, but still without any success.

Please help as I'm stuck into this.

[Solved] Kendo Grid, batch mode, determine when server side save is complete

Hello all! We have a KendoGrid on our MVC view, and it works great - the only question is when a user clicks the Save Changes button, how does the UI know when that action is complete if it is an AJAX request? In our case the grid is bound to server generated data, with Add and Save buttons in the tool bar. When a user enters invalid data into the grid as determined by the data annotations on the model, it works and shows the errors. We have no way of knowing if a successful save occurred though from what i've seen. Any ideas?

Thanks in advance!

[Solved] Why am I getting a number of symbols showing up in my tooltip

Hi,

I am looking to implement the kendo ui tooltip for MVC. With the way I have it implemented now, I am getting a whole bunch of random symbols showing up in my tooltip.

I've attached a screen shot of what I am seeing and attached the relevant portions of code I am using. I am hoping to fill my ServiceTypeToolTip div with significantly more content and there will be about 20 of these such sections on the page.

*I am using Kendo 2013.1.319

Any help would be appreciated.

Thanks!

@(Html.Kendo().Tooltip()
.For("#ServiceTypeImg")
.ShowOn(TooltipShowOnEvent.Click)
.AutoHide(false)
.Animation(true)
.ContentTemplateId("ServiceTypeToolTip")
.Position(TooltipPosition.Right)
.Width(120)
)

<div id ="ServiceTypeToolTip">
