Current RadGrid only has headers/header templates for column headers. The only way to have headers for each row would be to manipulate the grid data and adding the header for each row into the grid data itself. And if we wanted to group the row headers is another round of manipulating the grid data and also manually merging the cells. Is it possible to have to have it as a feature of the RadGrid just like column groups and column headers to simplify the task? example of the final output ->

Update data values using drag and drop directly from the chart, something like this:

A lot of customers would have this functionality without changing the HTMLChart controls.

We are missing the following navigation options (like the ones the RadScheduler has): go to the previous, next period (day/week/month) or go to a specific date.
Also, the views should show only the specified period (so the week view should show the current week by default). Now, if we have a task that started last year, even the day view shows several months of data.

I have two dates for a Task[Eg: Plan Dates & Actual Dates]. I want to show both plan and actual dates in same row, both with different colors. Below I have attached an image for reference.


To show both Planned and Actual dates(if any) for a particular single task on the same row with different colors for both.

Regarding RadGanttView (couldn't find it in the List)
Seems odd to me that you cannot override the default double click behaviour.
(in my case I would like to open a radWindow instead of entering Cell Edit Mode).

Couldn't find any event for it either client or server side.
This would be very useful if think, so I thought I try and request it :)
Both Task Click (SelectionChanged) and task double click should be accessible.
Talking about the grid part of the control.(left side)

I am migrating Excel Documents into Line of Business application into web pages. Which means everything excel can do, my client expect the telerik controls to do!

In your RadGantt controls, the Left hand side of the control is perceived to be a RadGrid this it is expected to have the same affordances of radGrid.
Which means that I expect the 
<CommandItemSettings ShowAddNewRecordButton="false" />
to work.

Which means I can apply all my learning of radGrid to the left hand side of radGantt.

There is a need to add custom buttons to the button strip of RadGantt.

The buttons for "Day | Week | Month" view appears on the top right of the RadGantt. The "Export to Pdf" button appears on the top left corner. I would like to add new buttons next to the "Export to Pdf" button. 

I would suggest taking this as a feature request. There are many scenarios where we need to have custom buttons in the toolbar of the RadGantt. Let the priority be decided by public opinion.

Currently, the RadGantt allows only format strings as a value for the WeekHeaderDateFormat property. For example, allowing a template similar to Kendo Gantt:
https://docs.telerik.com/kendo-ui/api/javascript/ui/gantt/configuration/views.weekheadertemplate#viewsweekheadertemplate 
https://docs.telerik.com/kendo-ui/api/javascript/ui/gantt/configuration/columns.headertemplate 

Use case - show week number instead of the dates. 

Workaround to show week number: The suggestion is based on the https://demos.telerik.com/aspnet-ajax/gantt/examples/accessibility-and-internationalization/localization/defaultcs.aspx demo. 

What you should add to the Gantt markup declaration is the WeekView-WeekHeaderDateFormat="dd/MM/yyyy" and OnClientDataBound="OnClientDataBound" properties. 

// https://stackoverflow.com/questions/6117814/get-week-of-year-in-javascript-like-in-php
function getWeekNumber(d) {
    // Copy date so don't modify original
    d = new Date(Date.UTC(d.getFullYear(), d.getMonth(), d.getDate()));
    // Set to nearest Thursday: current date + 4 - current day number
    // Make Sunday's day number 7
    d.setUTCDate(d.getUTCDate() + 4 - (d.getUTCDay() || 7));
    // Get first day of year
    var yearStart = new Date(Date.UTC(d.getUTCFullYear(), 0, 1));
    // Calculate full weeks to nearest Thursday
    var weekNo = Math.ceil((((d - yearStart) / 86400000) + 1) / 7);
    // Return array of year and week number
    // return [d.getUTCFullYear(), weekNo];
    return weekNo
}
function OnClientDataBound(sender, args) {
    if (sender.get_viewsData()[sender.get_selectedView()].type == "week") {
        $telerik.$('.rgtTimelineWrapper thead>tr:first .radHeader', sender.get_element()).each(function (index) {
            var $this = $(this)
            var datestring = $this.text().substring(0, 10);
            var date = new Date(datestring);
            var weekNumber = getWeekNumber(date)
            $this.text("Week " + weekNumber)
        })
    }
}

Allow setting a client template for the task's tooltip. 

Workaround: https://www.telerik.com/support/code-library/custom-task-tooltip

If the RadGantt custom column could be a type of "Rich Text", then we could insert any html including link buttons (e.g. edit task ),  Icons ( e.g. tick for task complete), or rich text in red, green or whatever. 
We would also need the data_bind event available to populate the custom field. :)

In the RadGantt, when using WebServices with the Gantt, there is no OnClientRequestEnd client side event.

We have a scenario where we're wanting to be able to track whether or not an insert/update event succeeded (and update a control elsewhere on our page if it did) or failed (and show an alert if it didn't). however there is currently no event handler for when WebService requests from the RadGantt have completed.

I would like to use the RadGantt control in combination with my own RadWindow that would pop up as an edit control when clicking on a row in the treeview control of that object. There currently appear to be no client side events on the treeview. 

I would like the treeview to have a third mode that is not exactly "ReadOnly=True" or "ReadOnly=False", but would allow the row to be highlighted on click. The row data would not be editable, and clicking anywhere in a row would raise a client side event that I could trap.

Thanks for considering.

Currently, the Headers are cycled by pressing the Tab key and this FeatureRequest is to improve the behavior and allow arrow navigation between headers, similar to the Kendo UI Grid:

• https://demos.telerik.com/kendo-ui/grid/keyboard-navigation 

Also, pressing Home/End should navigate to the first/last focusable cell in the row, while Ctrl+Home/Ctrl+End should navigate to the first/last focusable element in the Grid.

I think it would be a great addition to the grid control if there was an attribute that you could apply to the columns called "SortNullsLast" or something along those lines. This attribute would modify the grid's sorting functionality and only apply the ascending or descending sort to non-null values.

Currently when you sort ascending, null values are sorted to the top of the grid. This new attribute would allow the non-null values to show up at the top in ascending order.

An example of why this would be useful is having a grid that tracks an optional requested completion date of a task. You would want to be able to sort the grid so that the earliest date shows first in the grid. Right now, any records that don't have this optional date would show first, which doesn't make sense.

How can I search for multiple items?

For example, "Telerik"  or "UI"?  By this, I mean that I put  "Telerik" and "UI" in the searchbar. Refer to https://demos.telerik.com/aspnet-ajax/pdfviewer/overview/defaultcs.aspx

Add the ability to upload whole folders to the RadCloudUpload, similar to the FR for AsyncUpload:

• https://feedback.telerik.com/aspnet-ajax/1376730-add-folder-upload-with-drag-and-drop-radasyncupload

Under heavy load in a multithreaded environment, a concurrency issue can occur, related to System.Collections.Generic.Dictionary`2.Insert

This might lead to High CPU usage and might require an IIS restart.

Workaround:

• Use CDN for Telerik styles and scripts
  • https://docs.telerik.com/devtools/aspnet-ajax/controls/scriptmanager/cdn-support/custom-cdn-provider 
  • https://docs.telerik.com/devtools/aspnet-ajax/controls/scriptmanager/cdn-support/overview 

   

We are trying to get our site to be WCAG AA compliant however the Telerik DatePicker appears to have inline styling on the second popup for month selection:
