Bar series with Point series in one cartesian chart?

Hi,

I am having problems displaying Histogram(bar series) with Points(point series) within them in a CartesianChart in WPF.

If I declare only one single Horizontal axis(Categorical) for both the series, then the series are appearing one after another horizontally.

If I declare two separate axis(categorical) for both, then the scales arent getting adjusted equally.

I would want to achieve such that either both share a single Horizontal axis and both series are drawn overlapping or

let both series have two separate axis and their scale is equvivalent.

How do I achieve this?

RadRibbonGallery MVVM

Hello,

I'm trying to add RadRibbonGallery to MVVM examplefrom the Example Demo:
\Telerik_UI_for_WPF_2018_1_220_Demos\Examples\RibbonView\MVVM

so i already add a template selector and add the elements in view model
the RadRibbonGallery displayed

BUT, the images inside each item has border when mouse is hover, and on click the item NOT selected,

only if i click on the the BORDER of each item inside the Galley, then the item selected

here is my progress until now:

the template selector:

GridViewRow template customization

Hi.

I have RadGridView with some 12 columns defined. This grid is bound to list of business objects and is editable.

I would like some rows of the grid to have changed layout.

I was able to define and apply ControlTemplate for GridViewRow, to display row data in one TextBlock that has width equal to the width of the Grid.

This template works fine for rows selected by one of the businessobject properties (using DataTrigger)

But I need to further modify this Template in this way that, its width should be equal to the total width of the first 8 columns and the last 4 columns should be visible and editable as in standard grid row.

In existing threads i didn't found any soulution to this problem, so I would like to ask how can I achieve such an effect?

I am using RadGridView version 2018.1.

Thanks in advance.

RadRibbonView is too high in the Fluent theme

Hello,

In the documentation, it is said that the image for a large button should be 32 x 32 pixels. With images this size, there is a huge empty area in the bottom of the RibbonView.

If the height is correct, the buttons should be vertically aligned... or, better, a top margin should be added.

See the screenshot

RadRibbonButton has its content left aligned in Fluent theme

Hello,

When a button has a text that is larger than 32 pixels, the content of the button is left align, but it should be centered, as in other themes.

See the screen shot for an example.

RadGridView - Data Virtualization

Hi,

I have a requirement to populate high volume of data(>50000 rows) in the gridview. I feel data vitualization/lazy loading is a good way to implement this. If I load 500 records at a time and keep loading while scrolling the content the next set, how can I address the following scenarios :

Select All option(for the whole underlying datasource)
Sorting, grouping features of the grid(for the whole underlying datasource)
Export to excel feature(for the whole underlying datasource)

Assuming all the records are not loaded for the above mentioned scenarios,

Regards,
Anand

GridView control dynamic column binding

Hi,

I have a requirement to implement a screen to show information in a grid with distinct columns/data for each button click(3 buttons).

For e.g., Button1_Click -> Grid must render columns ( Column1, Column2)

Button2_Click -> Grid must render columns ( Column11, Column12, Column13)

Button3_Click -> Grid must render columns ( Column21, Column22, Column23, Column24 etc.,)

I do not want to have 3 different grids for each button click by show/hide and have their exclusive bindings just because i feel it is not a right approach. Also I should be able to bind my data fields appropriately to the columns. I really appreciate if someone can share their experience to achieve this in a manageable and scalable way. Hope the scenario is self explanatory. Thanks in advance.

Regards,

Chand.

Multiple problems with KeyTipService

Hi,

I'm running into some issues using the KeyTipService with the RadRibbonView.

The first issue is that if the ribbon is minimized, the key tips seem to display most of the time, without popping up the ribbon tab. (See attached picture). I say most of the time, since once in a while it will actually work (the ribbon tab will open), but then sometimes after it does work (the ribbon tab opens), it might not close afterwards! (e.g., if the user clicks the application title bar instead of choosing a key tip).

The second issue is that when the ribbon is NOT minimized, the key tips seem to work pretty well, except for an annoying focus rectangle that I cannot seem to get rid of when displaying a menu (see attachment). I have tried setting IsFocusable to false and the like, but still can't get it to stop showing. Any tips on how to get rid of that focus rectangle (using RadContextMenu and RadMenuItem).

Finally, when the key tips do display, they display very slowly. i.e., when using ALT, then picking a tab, the key tips on that tab take a long time to display. So much so that you can see them pop up, gradually, from left to right. At first I thought it was a deliberate animation, but seeing that Office and other applications show the key tips instantaneously, I am wondering whether it's just a performance issue, because if the key tip the user wants is to the far right hand side, then they have to wait a couple of seconds to see it.

As for these three issues, the one I am most concerned about is the flaky behavior with key tips when the ribbon is minimized, because it looks out of place and users will have a difficult time trying to navigate it. They shouldn't have to have the ribbon maximized in order to use key tips.

Kind Regards,

Wayne.

as you noticed in the last details, it says 3 objects after opening the window and closing for three times. I have spent quite long time trying to figure out what is going on, but I couldn't. I worked on different screens with RadGridView and pretty much same controls and there is no problem. Did I miss out anything?
If you need further details, let me know
FYI: when RadGridView is commented out, there is no problem
