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.

At the moment only the TelerikTextBox has a Title parameter that I can use to add a tooltip to it.

ADMIN EDIT

A workaround for the others can be wrapping them in another HTML element whose title attribute you can use.

Here is an example with the checkbox:

<span title="the checkbox title">
    <TelerikCheckBox @bind-Value="@theBool"></TelerikCheckBox>
</span>
@code{
    bool theBool { get; set; }
}

Subject says it all.  We're porting a large WPF application to Blazor and need WPF Telerik controls with corresponding functionality.  One of those controls is the breadcrumb control.

Would need to work in Blazor client or server topologies.

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

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,

is there a way to use the kendo-popup from https://www.telerik.com/kendo-angular-ui/components/popup/ in Telerik UI for Blazor? Is it a planned feature for the future?

Thank you,

Hello.

I have a scenario where I need to make some nodes in a TreeView checkable and some not.  It would be nice if there was an "IsCheckable" binding that determines whether a node should render a checkbox or not.

Although I've no use for it yet, the same could be done for "IsSelectable".  

Is there some way to do this already, and I'm just not seeing it?  I'd prefer not to use JavaScript interop, or recreate the checkbox functionality through an ItemTemplate.

I'm using a numeric textbox to handle a decimal value with the Format is set to "#,0" (which it needs to be since the client's specification is to have a whitespace as a decimal separator). While the entered value is less than a thousand then the entire value gets selected when tabbing into the component, but once it's large enough to display a group separator tabbing just puts the cursor at the end of the input without selecting the value.

I believe this to be a bug.

Now we can expand/collapsed tree view item using bound read/write model property.

We need to bind read-only property or controll expandability outside of tree view.

Examples:

• Expand tree view item when IsActive read-only model property is true
• Expand/collapse all tree items with a button click

Thank you

Hi,

it would be nice to have a single button in the GridToolbar that opens the column chooser menu or something like that (popup?).
Often we need to save space in a grid and disable the menu option for the columns but then we lose the ability to choose which columns the user might want to disable. This also apply to very small columns with small header information, e.g. if you just need 2 or 3 letters to describe the column data then the menu with its three dotted button is to large.

Best Regards,
Thomas

When a content is displayed in TelerikWindow and a TelerikTreeView`s item is expanded, the item`s content is above the window one due to higher z-index.

To fix it, use this CSS:

Using your tree view live sample, filter the list with "1", then try to expand "Test1" - crash.

I would expect "Test1" to apprear in the list but without the expandable icon or the expandable icon does nothing when clicked

Hello,

I have updated Blazor UI to the latest version (2.9.0) and some of my controls lost their state.

Let me explain:

I have a page with 4 tabs (TelerikTabStrip), if i choose the value of a dropdown (TelerikDropDown) in the first tab and move to the second tab and then come back to the first tab, the value would be lost and the dropdown is empty however, if i put a breakpoint and look at the model, it shows that the value is still preserved.

Is there something i am missing? is this an update gone wrong (on my side)?

I have downgraded back to 2.8.0 and it works as expected.

Thanks.

We have had major complaints from users when using the combo box.  They use the filter, see the first item highlighted, then click tab and the item in not selected.  They do a lot of data entry and don't want to use the mouse or use the down arrow to select it.  They are used to a regular HTML select control which works that way.  Is there any Javascript workaround for this?  If not, I probably have to go back to using a standard select box.  The reason I am using the combobox and not the dropdown is because your dropdown doesn't support tabbing out of the box and that was a deal breaker for them.

I saw an article on using the PopupClass for the ComboBox but that isn't a supported property.

Thanks!
