any other way to data bind than via @bind-Value?

[Arnaud]

Hello,

 

I am using Telerik DDL for Blazor (2.6.1).

For now it works as expected.

 

Right now, for what I could see, you can only databind to the selected VALUE (via bind-Value property).

Is there a way that I missed, to databind via the selected ITEM?

 

I use this code:

<TelerikDropDownList Data="@MyListOfMyItem"
TextField="@(nameof(MyItem.prop1))" ValueField="@(nameof(MyItem.prop1))"
@bind-Value=@MyItemSelected
TItem="MyItem" TValue="string"/>

 

At the moment, I can only access to the prop1 property of the selected MyItem element (using @bind-Value).

I can obviously deduct the MyItem element from the collection via LinQ,

but I would definitelyprefer to have another binding property that directly returns the MyItem element to me.

In other words, something similar to the SelectedItem from MS components.

Is there a way to do that? If not, is it something that you plan to release in the future?

 

Thx in advance

Hello Arnaud,

Yes, you can get an instance of the model when an item is selected a dropdown. 

You can do so by following the instructions below:

• Use the unique identifier you get from the component (the Value)
• Get the entire model from its data source by filtering it (e.g., by using the Where() operator).

More information (like why this cannot be implemented out-of-the-box) and working example can be found on our Knowledge Base from this link: https://docs.telerik.com/blazor-ui/knowledge-base/dropdowns-get-model
