Hello,

i need some help regarding a problem with the context-menu. i am total new with the framework so maybe my question sounds a little stupid. sorry for that. 

When an entry in the context menu is clicked twice (kind of double-click) the app has a problem with the request that is still beeing executed by the first click. 

So how can i disable a context menu-entry inside a click handler. We are using typescript.

The handler starts with 

    private OnMenuItemSelect(event: ContextMenuSelectEvent): boolean {
        const item = $(event.item);
        const menuItemId = this.GetMenuItemIdFrom(item);
        if (menuItemId == null) {
            return true;
        }
        const menuItem = this.GetMenuItemById(menuItemId);
        if (menuItem == null) {
            return true;
        }

 

How can i access the clicked entry and disable it ?

Hi

On Kendo Grids we use the following template on a column to convert the string to a href link:

(e.g. workItemLink = <a href="/link/to/a/page.aspx?Key=ABC">ABC</a>

columns: [
	{
		field: "workItemLink",	
		template: "#=workItemLink#",
		title: "Work Item Ref",
		width: "110px"
	}
]

This doesn't seem to work on kendoGantt columns:

columns: [
	{ 
		field: "workItemLink",
		template: "#=workItemLink#",
		title: "Link"
}]

Are templates not supported in gantt charts? Is there another way to add a link the column part of the gantt?

Thanks
Ben

greetings.

I drew a line chart where the x-axis is the time value and the y-axis is the number.
How can I highlight (or select) the place corresponding to the time axis of the line chart by clicking the time text link outside the chart?

 

thank you for answer.

I have a parent kendo grid which has a detail kendo grid with a custom template. The custom detail template includes a tab strip with two tabs. Each tab includes a single kendo grid. I am using the default create and edit kendo grid buttons with some custom text. The controls on the parent grid seem to be working normally. When I press "Add New Row" a kendo editor pops up (pop up editing enabled) and in the background I can see that a new row is created. However, on two detail grids which are contained within each of the two tabs it seems that the pop up create and edit functionality is not working correctly. A window is popped up and the editing/creating actually works, but the grid acts strangely - mainly when I press the cancel button to exit out of an "edit" event for a particular item in one of the detail grid rows. 

I believe that I have included the appropriate amount of code to look into the issue. 

Thanks for the help! 

<div data-ng-controller="GridCtrl as gridCtrl"><script type="text/x-kendo-template" id="detail-grid-template"> <div class="detail-tab-strip"> <ul> <li class="k-active"> Grid One </li> <li class="k-active"> Grid Two </li> </ul> <div> <div class="grid-one"></div> </div> <div> <div class="grid-two"></div> </div> </div> </script><script type="text/x-kendo-template" id="grid-one-editor"> <div> <ul class="fieldlist"> <li> <label for="GridOneID">ID</label> <input type="text" class="k-input k-textbox full-width k-state-disabled" disabled="disabled" name="GridOneID" data-bind="value:GridOneID"> </li> <li> <label for="GridFieldOne">One</label> <input type="text" class="k-input k-textbox full-width" name="GridFieldOne" data-bind="value:GridFieldOne"> </li> <li> <label for="GridFieldTwo">Two</label> <input type="text" class="k-input k-textbox full-width" name="GridFieldTwo" data-bind="value:GridFieldTwo"> </li> <li> <label for="GridFieldThree">Three</label> <input type="text" class="k-input k-textbox full-width" name="GridFieldThree" data-bind="value:GridFieldThree"> </li> <li> <label for="GridFieldFour">Four</label> <select id="GridFieldFour" name="GridFieldFour" data-bind="value:GridFieldFour"></select> </li> <li> <label for="GridFieldFive">Five</label> <select id="GridFieldFive" name="GridFieldFive" data-bind="value:GridFieldFive"></select> </li> </ul> </div> </script></div>

When I export to Excel using the Export to Excel button in a kendo grid, the Excel file generated has the grid column titles as the Excel column headers.  Which is what I want.

When I export to Excel using the grid.exportSelectedToExcel(true), the generated file has the grid column fields as the Excel column headers.  I don't want the field names exposed.  How to prevent or change this?  Thank you.

Code:



Results for each type of export.  The top part of the image is the desired result.

Hi...

In the Syncfusion Gantt Control, it's very easy to show/set the task dependencies (see screenshot of task properties bellow).

 

How to do the same in the jQuery Gantt?

Thank you.

Hello,

Cascading Comboboxes do not clear and reset values correctly when Virtualization is enabled.

I mimicked the bug though Codepen.

Find it here and follow instructions to reproduce the bug.

Hi

my pager in the grid component does not show the active page:

analysing the HTML there is a class k-state-selected

but this class is nowhere defined in the current default theme

"@progress/kendo-theme-default": "^5.12.0",

 

checking with the working demo from the kendo page the pager as rendered as buttons instead of li and there is a class k-selected which is also defined in the theme:

I'm working with all current versions:

"@progress/kendo-angular-buttons": "^7.0.0",
"@progress/kendo-angular-common": "^2.0.0",
"@progress/kendo-angular-dateinputs": "^6.0.0",

Hello, 

I have recently updated from R1 2022 to Kendo UI R1 2023, and now I am facing some backward compatibility issues regarding grid component.

New version does not support optional chaining in grid column field, for example:

columns:[{

field: "object?.property?.property"

}]

such approach throws an exception on sort operation (it works as expected in R2_2022).

Is there a fix foreseen in the near feature?
