I would like to suggest couple of helpful features on the OnRowRender event on the grid component.  I know these can be done with a custom row template.  But if a couple of additional properties would be tacked on to "GridRowRenderEventArgs args", it would be helpful.

1. Columns and Cells collection
   Would like to override the display of a databound item, but not the underlying data.
   
2. Selection
   Based on props of the databound item, it would be helpful to disable the ability to select the row.

So the Date Filter is not working.

I believe this is because my data has Time with it, I couldn't find any help on how to ignore the time part in the date filter.

 <GridColumn Title="Date Visit" DisplayFormat="{0:D}" Field="DateOfVisit">
                    <Template>
                        <label class="gridLabel">Date Visit:</label>
                        @{
                            if ((context as Visit).DateOfVisit!= null)
                            {
                                @((context as Visit).DateOfVisit.Value.ToShortDateString())
                            }

                        }
                    </Template>
                </GridColumn>

Hello

I noticed the DateRangePicker "OnChange" fires "on blur".

Confirmed by the docs;

https://docs.telerik.com/blazor-ui/components/daterangepicker/events#onchange

Is it possible to expose OnInput even for a "react style" onchange event?

https://linguinecode.com/post/onblur-vs-onchange-react-text-inputs

I think the StartValueChanged and EndValueChanged events have the same behaviour so unbinding might not be a solution..?

Attached is a use case where it is confusing because the events are not in sync... You'll see the grid data changes (data bound), but OnChange after you click out.

I wasn't sure if I should report this as a bug or not. With a modal window, you can tab beyond the modal window into the URL, and then continue on into the page behind the modal window itself. I was able to recreate this on the Modal demo, and fire a search, even though I couldn't click to get there. As I saw in another post that it is essentially a viewport modal (https://feedback.telerik.com/blazor/1510450-prevent-the-user-from-dragging-a-window-out-of-the-viewport), would it be possible to force modal to be system modal, as was available back in the ancient Winforms days?

ADMIN EDIT

That's how a web page behaves. Code in a web page cannot and should not prevent the user from using their OS. The browser chrome (address bar, buttons and so on) are part of the OS, and as such are beyond the sandbox of the web app. The web app is limited to the viewport, it cannot go out of it, or interact or control elements outside of it. Anything else would be a severe security issue.

A system-wide modal dialog is only possible though a native application, but not in a web application.

Similar to how TelerikTextBox lets you set a label that moves above the control when filled, TelerikComboBox and TelerikMultiSelect also need this.

Currently you can set a label on TextBox but not some of the other editor controls.

Here is a screenshot comparing the textbox with the combo:

Here is the material UI demo for a combo with this feature:

https://material-ui.com/components/selects/

The attributes that the Telerik Input components, FormItem, and FormGroup should all be consistent in the attributes that are supported.  For example, the TelerikSlider component doesn't support an Id property.  The FormGroup component doesn't support a Class property.

If I place the Slider inside a FormItem Template and provide my own label. I can't associate the label with the Slider since there is no Id property.

Also, if I am using a FormGroup to make sure that two input controls are shown horizontally install of vertically, I can't override the gray horizontal rule that shows with the group, especially when I am not providing LabelText.  I don't want to override this at the TelerikForm as I would like the default behavior in specific instances.

The attached screen shot highlights the issue.  Here is the razor component markup.  Note: Replace the custom RecSetSelector component with a dropdownlist.

I see a good solution for angular (PopupSettings.appendTo)

https://www.telerik.com/forums/datepicker-doesn%27t-open-in-ionic-modal#5117655

but blazor only has the PopupClass attribute to work with.  Assigning that a class with a large z-index didn't help

It would be really cool to be able to edit documents much like the WPF syntax editor.

Our use case is that we use blazor for our admin tools and we need to give a better look and feel (color coding) to some stored SQL and XML.  Nothing fancy just a better experience.

Hi,

I have a grid, it has quite a few columns - maybe 10-15, and this is causing 2 problems which are kind of related.

First problem is it tries to squash them all onto the screen making them all narrow and that hides the header text - I have played with horizontal scrollbar but so far I've only managed to resize them after it loads (or to workaround that I have tried save state after I've resized them with some success, but i'd really prefer the default starting point to be wider than the screen - if you have an example you can show me how to do this?)

Next problem is when I add a filter row to it - its basically unusable.  Even though the columns are narrow, they look like they should be wide enough, but instead what happens is the filter button appears in the middle by itself and nothing else appears - sometimes I see " ___ Y      "  but most of the time its "        Y         ".  It seems very poor use of space by default.  This is the material theme. 

Can you help?  I did try with the filter menu but it is more complicated for our users and they prefer the idea of filterrow, plus it also crashes intermittently (see below for callstack).

There doesn't seem to be a way to deselect the selected row either by clicking on a selected row again or by two-way-binding and setting it to an empty list.

This would be pretty handy as currently the only way that makes sense for me is to make no use of selection mode at all.

Hi, 

I reported this last week but it got declined ??  Perhaps a picture will help

The default grid displays the filter icon OVER the text and this makes the text unreadable.  This is just the material format from your websites themebuilder

The icon should be closer to the column width adjuster - as you can see from the attachment there is more space between the columns than there is text

I would expect it to be  "| Description  Y |"  and not "|  Desc... Y        |" which is what its doing.  (really the space between the filter icon and the column adjusted is just wasted and there seems to be no way to fix it)

I've tried to move the k-i-filter using CSS and while giving it a left margin of 32px is working ok and making it look reasonable, it still has the circle highlighter when you click it in the wrong place and I can't figure out how to move that also.

It would be nice to switch the color schemes used by the telerik Blazor components on-the-fly in an application (i.e. switch from light mode to dark mode). I realize you have a JS approach to this problem, however that requires maintaining multiple stylesheets and custom javascript, which we are trying to avoid in a Blazor project. I like the approach used by MudBlazor where basically all css colors are variables that can be easily switched at runtime without any javascript:

https://mudblazor.com/wasm/customization/theming/overview

Example live daylight map: https://www.flightradar24.com/

Hi,

Would be great if there could be a Timeline component for Blazor. Just like the Timeline component for WPF at "https://docs.telerik.com/devtools/wpf/controls/radtimeline/overview".

I need that component or something similar to show time based instances of activity on a particular item. A lack of such visualisation feature is making us hold on to the WPF one. 

Thanks.

Hi,

we are having a hard time to come up with a general application layout (menu/navigation).

We found PanelBar, Menu and Drawer... are there any other controls related to menu & navigation?

A more UX oriented documentation (and not only for the technical components individually) would be nice e.g. like they do it here: Overview | Clarity Design System

Kind regards

Steffen

Hi !,

I just installed and started to use Telerik Blazor , all controls are working fine but when trying to use the Dialog Component, after adding the cascading parameter in the code section i getting the following error :

Thank you for your support.
