I have a numeric text box that is bound to a nullable int. There is also a combo box on the page that will auto set the value and disable the numeric text box if certain values are selected. as follows:

<TelerikComboBox Data="@TareTypes" 
                                     TextField="Name" ValueField="Id"
                                     ValueExpression="@(() => Material.TareTypeId)"
                                     ValueChanged="@((int? e) => TareTypeChanged(e))"
                                     Width="200px"
                                     Placeholder="Tare Type" ClearButton="true"></TelerikComboBox>
<TelerikNumericTextBox @bind-Value="@Material.TareWeight" Arrows="false" Enabled="@tareWeightEnabled" ></TelerikNumericTextBox>                      
                    
                    
                    

and the code...

private void TareTypeChanged(int? tareTypeId)
        {
            Material.TareTypeId = tareTypeId;
            tareWeightEnabled = true;
            if (tareTypeId > 0)
            {
                var tareTypeWeight = TareTypes.Single(t => t.Id == tareTypeId).Weight;
                if (tareTypeWeight.HasValue)
                {
                    Material.TareWeight = tareTypeWeight;
                    tareWeightEnabled = false;
                    editContext.NotifyFieldChanged(editContext.Field("TareWeight"));
                }
            }
        }

the following steps should reproduce the problem

1. enter a value in the numeric text box and then clear it out
2. select a value from the combo box that auto sets the numeric text box value and disables it
3. select a value from the combo box that re-enables the text box. At this point the value is still visible in the text box (as it should be) and the text box is enabled
4. Focus in the text box. this causes the number to disappear. it's as if the number was just a place holder which clears out when you focus on the control.

Hi!

Is there a reason the label has to be defined separately from the label? We'd love a "Label" parameter to be specified in the TelerikCheckbox control directly instead of having to create a separate element

If I set the Visible parameter to false for either ToolBarButton or ToolBarToggleButton it does not hide them from the UI. 

<AdminEdit>

A workaround would be to use the Class parameter and add a display:none CSS rules. 

Code snippet for the workaround:

<style>
    .hidden-button{
        display:none;
    }
</style>

<TelerikToolBar>
    <ToolBarButton Class="hidden-button">Hidden button</ToolBarButton>
    <ToolBarButton Icon="@IconName.Star">Visible button</ToolBarButton>
    <ToolBarToggleButton Class="hidden-button">Hidden toggle button</ToolBarToggleButton>
    <ToolBarToggleButton @bind-Selected="@isSelected">Visible toggle button</ToolBarToggleButton>
</TelerikToolBar>

@code {
    public bool isSelected { get; set; } = true;
}

</AdminEdit>

I would like to be able to style, for example, all grids on my page with certain rules. Thus, if each component had a unique class in its top-level rendering I could use it to cascade through it.

This also applies to dropdown/popup elements (for example, be able to target the popups of dropdownlists).

Ideally, elements that have additional popups (like the dropdownlists) will also expose parameters like DropDownClass so I can add my own class to them and style them per instance, so I don't affect all other instances in my app.

We are looking to update our application to Blazor but one of the controls that we use is the Filter Control ( from .Net Core controls).

Any chance a Blazor control can be created for this?

Hello

Just a minor request re. the Grid search box :)

The typical UI behaviour of a search box, is that when you start typing in it, an "X" will appear within the box, allowing you to clear the value.

This would also be consistent with the Blazor combo-box behaviour.

I'm currently migrating a project from ASP.NET MVC to ASP.NET MVC Core.

In the server code I'm using a DataTable from the database which is converted to a DataSourceResult with ToDataSourceResult.

It worked fine in the ASP.NET MVC version, but the same code in the ASP.NET MVC Core version throws an exception when using aggregate functions.

System.InvalidOperationException: 'No generic method 'Sum' on type 'System.Linq.Enumerable' is compatible with the supplied type arguments and arguments. No type arguments should be provided if the method is non-generic. '

First of all, The team loves the product, and development is going 10x faster with a UI library with so many features.

But we're looking for making diagrams inside our application. Something like https://www.syncfusion.com/blazor-components/blazor-diagram

is it a feature currently in the backlog or is it possible to put it there?

That will make us possible to make a flowchart over what assets are connected to each other in our data center

As we are porting many of our applications from Telerik MVC to Blazor, our clients are complaining about particular features no longer being available.

One of which is the multiline edit for incell edit that is available in Telerik-MVC.

This feature is nice as it allows the grid to have a very "excel - like" feel to it, with a small triangle in the corner to indicate the cell/view-model has been edited.

As is, the user is forced to edit the data line-by-line, and save per line.

In real client work, data is not necessarily modified in this linear/per-row fashion.

Take for example, a client has a list of delivery dates which need to be updated down 1 column, current functionality is painful, as you need to edit 1 date, click save, then move onto the next row instead of just moving down the rows and clicking save after you have finished your edits (like you can with Telerik MVC grid).

My rationale for this feature add: The "big data" age is upon us - and blazor is very well suited for these types of applications being strongly typed/c# etc; would be great to see Telerik lead in rich data input components for data heavy applications, and the grid is the most core UI component hence should be the most feature rich and performant.

Just upgraded to Devcraft complete and I needed a Progress bar and was not able to see it on the current controls.

Will you add a Progress Bar Control for Blazor?  I want to use Telerik on all controls in my project as much as possible instead of pulling another control from the public nuget repository.

Thanks.
