Hello, 

Any way possible that a custom method can be fired using the selected items from multiselect. There is absolutely no where in the documentation to specify this. It is only provided SelectedItemsChanged that takes lambda. When trying to fire a custom method on selected items when the user clicks a button, the follwing   error is thrown: 

Argument 2: cannot convert from 'method group' to 'EventCallback' .

It is provided a link below : The lambda expression in the handler is required by the framework: https://github.com/aspnet/AspNetCore/issues/12226. 

It doesn't really make sense why this link has been provided as it takes you to a blog page and absolutely no solution is provided.

So may I ask, how do you fire a custom method only on the selected items?

Thank you.

Kind regards

Hello,

Any way possible that you can use GridCheckboxColumn multiple select and fire a custom method only for those selected items? I didn't see anywhere is the documentation if it's possible. Thank you

Problem Description

In my code currently we have a Telerik DropDownList that triggers a redraw of a TelerikGrid based on the option selected within the dropdown.  

The current challenge is that when the DropDownList selection is changed, the focus is still set to the DropDownList.  The effect this has is that when a user attempts to click the edit or add buttons within the Grid, the user has to click twice with the mouse.  The first click doesn't seem to do anything because it's that click that causes the focus to be taken off of the DropDownList, while the second click actually allows the desired action to be triggered.

Note below, how focus is still set to the dropdown

The problem is that the DropDownList doesn't have a Blur() event, and none of the Telerik Components within the page (Form, Grid, and all of their child components) have the SetFocusAsync() method.  

Current Solution in Place

The current solution we're using is to have an invisible TelerikTextBox on the page that we call SetFocusAsync on when a selection is made to the DropDownList. This is not the most ideal solution and I am reaching out to see if there is a better way to handle this.

Thank you so much, and enjoy your day!

Hi,

How do I add colors to the Editor text color picker in the editor?

The colors Red, Purple, Pink, etc are missing from the color picker.

The editor can support the missing colors, but they are included in the color picker.

Thanks,

Hi, do you have a working sample of Cascading DropDownList with Virtualization?

My use case:

There are 2 dropdowns (A and B), dropdown B cascaded from A, dropdown B has virtualization turn on (large data) .

I want to use the onChange-virtualization so I can still use my standard bind-value.

I tried to follow your example https://docs.telerik.com/blazor-ui/knowledge-base/samples/dropdownlist-cascading-samples.zip from your article https://docs.telerik.com/blazor-ui/knowledge-base/dropdown-cascading

The problem with that "onchange-virtualization" sample is the second dropdown is still loading all the data

I already tried not calling GetAllproducts() but just calling Rebind() (on the productDropDown) now the problem is the selectedValue on the second dropdown won't change after the first dropdown value has been changed. This does not happened when I use non virtualization.

The other problem with Rebind(): the skip value is not reset to 0.

So do you have the latest sample for this common virtualization use case?

Thank you

Since upgrading from Telerik 3.0.1 to 3.1.0, DateInput controls no longer bind to properties for me. 

The following works in 3.0.1 but not 3.1.0

@page "/TestPage"

<p>Message: @Message</p>
<p>MyDate: @MyDate</p>

<TelerikTextBox @bind-Value="Message"></TelerikTextBox>
<TelerikDateInput @bind-Value="MyDate" Format="dd/MM/yyyy"></TelerikDateInput>

@code {
    public string Message { get; set; }
    public DateTime MyDate { get; set; }
}

I would like to limit how many nested groups in the Filter the user can make.  Something like MaxNestedDepth. 

Does something like this exist? I couldn't see it in the docs. 

Thanks.

PS: there is no tag for the Filter control, Grid was the closest related control I could find.
