I bind the TelerikEditor Value to a property that is reloaded with different unrelated content. The editor keeps the Undo/Redo stack so for the "second" content I can Undo back to the "first" content. I'd like to be able to clear the Undo stack.

Hi,

  I had to figure this out myself for the ComboBoxSettings because there is no documentation for this. 

  The MinWidth works from the Combobox width or greater extending the size of the popup and

   MaxWidth only creates a popup width of the Combobox only. 

Please document this feature and how to use it.  And, is this intentional because it wasn't intuitive for me to figure out.

I created a REPL for you to test this out for yourself. 

https://blazorrepl.telerik.com/GcYHOXGQ46qRkI8K54

When a culture that has comma for decimal separator is used, the ColorPicker formats the rgba() CSS rule as rgba(255,255,255,0,6) which is incorrect. The alpha value should always have a dot as a decimal separator.

<TelerikColorPicker @bind-Value="@value">

@code {
    public string Value { get; set; } = "#282f89";
}

Set the culture of the application so that the default decimal separator is a comma (el-GR).

// in Program.cs file
CultureInfo.DefaultThreadCurrentCulture = new CultureInfo("el-GR");
CultureInfo.DefaultThreadCurrentUICulture = new CultureInfo("el-GR");

The rgba() rule is formatted as rgba(255, 255, 255, 0,6) but should be formatted as rgba(255, 255, 255, 0.6).

When a filter descriptor is created and the value is of type DateTime? (nullable DateTime) the serialized value is incorrect.

    DataSourceRequest request1 = new()
    {
         Filters = new[] {new FilterDescriptor("Test", FilterOperator.IsEqualTo, DateTime.Now.Date) {MemberType = typeof(DateTime)}},
         Sorts = new List<SortDescriptor>()
    };

    DataSourceRequest request2 = new()
    {
         Filters = new[] { new FilterDescriptor("Test", FilterOperator.IsEqualTo, DateTime.Now.Date) { MemberType = typeof(DateTime?) } },
         Sorts = new List<SortDescriptor>()
    };

    string query1 = request1.ToODataString(); // outputs $count=true&$filter=(Test%20eq%202022-05-12T00:00:00.0000000Z)&$skip=0
    string query2 = request2.ToODataString(); // outputs $count=true&$filter=(Test%20eq%202022-05-12%2000:00:00)&$skip=0

All I ask is to give a way to have a proper working datepicker. Like your javascript datepickers. That doen't care only for right values but for the person that uses it. Telerik was an early adopter in the Blazor ecosystem, I don't know how they haven't yet fixed their datepickers.

You can do this with many ways. I don't know them all but I will propose some here.

1. Create a second datepicker component that works properly.
2. Put an attribute in the component to work with free-text
3. Maybe if this attribute is on you can switch behind between 2 different components
4. Find a other solution of your own.

In the end behind the scenes you shouldn't bind the datepicker input in the datetime property but to a sting one. DevExtress has done this right.

This will solve

1. Proper user expirience when a user uses the keyboard to edit dates
2. Copy-Paste issue
3. Clear date parts issue
4. all from 30/4/2022 to edit to 31/5/2022 with out having to clear the input
5. Strange editing of years (I have an example in the end)
6. Allow to have dots or what ever the users want between dates numbers. (e.x. 13.3.2022 )

I this is a trade-off and you will have senarios with wrong inputs and other things, but you already know them from the javascript world, and it's less importand than the aboves.

*Strange editing of years

Lets say that we have the year 1998 19and we want to put 2014.

the users See
-> 1/1/1998
-> 1/1/9982
-> 1/1/9820
-> 1/1/8201
-> 1/1/2014

That's not user friendly, and is very disturbing.

The idea of the feature is to be able to customize the list of FilterOperators displayed in the list of the FilterRow and FilterMenu.

FilterRow UI element

FilterMenu UI element

Docking Control like WPF Docking Control: https://www.telerik.com/products/wpf/docking.aspx

As a user, I would like to ability to pin one to many row(s) in a grid so that the pinned rows are always the first rows at the top of the grid.

If a filter is applied, the pinned records that match the filter should be displayed first.  Non matching rows may be hidden.

If a column sort is changed, the pinned rows should be sorted then the unpinned rows should be sorted to ensure the pinned rows are always at the top of the grid.  

As a developer, Pinning should be a optional feature configured when the grid is setup.

This essentially would only add a data populated "pin" column the user can toggle on or off, but the real effort in this request is around the sorting and filtering to ensure when the user clicks a column the event is captured, and the sort is submitted as pin column, then the selected column, to ensure the pin takes precedent.  

Currently, the validation of the grid can be disabled altogether via the GridValidationSettings.Enabled option. However, we cannot control the validation of the grid per column.

Also, we cannot control when the validation is triggered. The simple inputs expose the ValidateOn option, but it cannot be set to the default editors of the grid without the need for an explicit declaration of a custom editor.

Hello,

I'm trying to find a way to update an ArcGauge Blazor component in a way that animates from the old value to the new one: currently, this widget totally restartes the animation from the min value to the current one, whenever it refreshes. To be more specific, I'd like to achieve the same behavior as the Angular ArcGauge demo animation.

Is there any way to accomplish this in Blazor?

Kind regards,

Gabriele Volpato

Steps to reproduce

1. Add a DatePicker
2. Bind it to nullable DateTime object
3. Use the dd.MMM.yyyy format
4. Select any date and when the popup is closed press any numeric key on the keyboard.

My users want to paste dates in the date inputs (date pickers in our case). This seems to work in Kendo, but does not work in Blazor, even when the format of the copied data matches the Format of the component.

<p>
    Try copying this date which is valid in the current format: 23/03/1998
    <br />
    then paste it in the date picker and see what happens to the <code>TheDate</code> field
</p>

@TheDate
<br />

<TelerikDateInput @bind-Value="TheDate" Format="dd/MM/yyyy" /> @TheDate.ToString("dd/MM/yyyy")

@code {
    DateTime TheDate { get; set; } = new DateTime(2019, 11, 27, 02, 03, 44);
}

ADMIN EDIT

Allowing the paste into the DateInput (and by extension date picker,...)  would have a lot of cases to control and that is why we have not yet enabled it. If the format is M/d/yyyy, for example, validation for numbers lower or equal to 12 would not be possible when the month is regarded. If the user pastes 8/2/2020 could mean two things - 8th of February 2020 or 2nd of August 2020. This might cause issues as the data that goes to the database might be incorrect and causing the application to misbehave.

That being said, how would you suggest handling the pasting of dates in the component. How would you like from us to handle the format difference of the dates? Please comment below.

Initially, the grid is filtered by "Is FTE? = True". It shows 20 lines. The sum of "Hours" should be 800. But the footer shows another value (depends on the random logic which you've implemented). See the attached screenshot.

Then, when changing the filter, the correct sum is shown.

But I need the correct value initially...

Re: I've just found out that using the OnRead event instead of the standard data binding solves the issue. Better said, it's a possible work-around.

Hi, It is possible to have a component that enables the use of the camera and to be able to scan barcodes or QR (1D  & 2D), for Blazor Web assembly and Blazor Server Side. Now this require JavaScript library like as QuaggaJS.

I think that having such a component is very useful and will allow you to build applications with advanced functionalities, other companies offer but only to generate barcodes or QR codes.

Best Rgards,

We need this existing control in a Blazor based control:

https://www.telerik.com/aspnet-core-ui/skeleton-container

We'll need to fall back to MudBlazor who does support this control.

We are existing licensed users under AVEVA.

Blazor load on demand (as users keys in) combo-box with multi column

When filtering using a GridSearchBox - to filter across all columns, we have an issue where if you change a GridColumns Visible attribute to false that row will still be visible in the grid results even though it no longer matches the filter.

Take this snippet for example: Telerik REPL for Blazor - The best place to play, experiment, share & learn using Blazor.

1. Use Search box and search for a Name. e.g "Chang"

2. Click "Toggle Name Visibility" button

Expected: Since Name column is now hidden, the column should no longer be used in filter and the row should no longer be displayed. In reference to the GridSearchBox: https://docs.telerik.com/blazor-ui/components/grid/filter/searchbox#filter-from-code where it's mentioned that the search box will filter only on columns that are visible. It doesnt seem to refresh the filter.

Actual: Row still displayed even though it no longer matches filter

Just wanting to raise this as an issue and also hoping you may know a potential work-around for this?

A potential work-around I have tried is re-applying the existing filter in the search box by following documentation here in the "Filter From Code" section: https://docs.telerik.com/blazor-ui/components/grid/filter/searchbox#filter-from-code

While I am able to apply a filter from code I cannot seem to retrieve the value that is currently in the search box as I want to reuse it. How can I achieve this with a GridSearchBox? There doesnt seem to be a property available on the GridSearchBox component for binding it's value. Would I need to create a custom filter input to achieve this?

Hi,

I try to implement a calendar there i use Range selection mode. I want the user only to click on the start range and then we will set end range in code based on the start range date. 

So i have set an RangeStartChanged event handler and that works but the gui component think i am in select end Range date so i want to exit the selection state after i have select Start date.

Is there anyway to do that?

ADMIN EDIT

A possible workaround for the time being - use Multiple selection mode of the Calendar and simulate Range selection. Handle ValueChanged event, programmatically add the desired count of dates to the selection and style them as range: https://blazorrepl.telerik.com/cQuzvKbO29J2Tbnt04.
