Splitter Pane SizeChanged event is not called

[Sorin]

Hello SF team,

I'm using the latest version 19.3.0.47

I noticed that the SplitterPane SizeChanged event is not being called.
This makes it impossible to assess the latest size value upon a resize event.

For example, in the code below the event is never called.

I attached code to demonstrate this.

Thanks,
Sorin

Hi Sorin,

On further validating the reported query “SizeChanged event of splitter pane is not triggered when resizing the pane”

The `SizeChanged` is an event call back of the property pane `Size`, it will not be triggered when resizing the pane using the splitter separator bar.

For your requirement to get the size of the pane when resize using the splitter separator bar, can be achieved by using the `OnResizeStop` event where the argument `PaneSize` returns both the left and right side pane sizes.

We have prepared a sample for your reference,

Code Snippet:

<SfSplitter Height="25%" Width="100%">

    <SplitterEvents OnResizeStop="@OnResizeStop"></SplitterEvents>

      . . . 

</SfSplitter>

 

@code {

    public string LeftPaneSize { get; set; } = "50%";

    public string RightPaneSize { get; set; } = "50%";

    public void OnResizeStop(ResizingEventArgs args)

    {

        var leftPaneSize = args.PaneSize[0];

        var rightPaneSize = args.PaneSize[1];

    }

}

Thank you Vinitha for the reply and suggestion!

I am able to use the code provided to achieve my project's needs.

Just out of curiosity, will SF eventually fix the  SizeChanged event? 

(it would be nice because then I can just bind my parameter directly to it)

Hi Sorin, 

 

 

We want to let you know that the ‘SizeChanged’ event is an event call back of the property pane `Size` and it will set a callback of the bounded value, it will not trigger when resizing the pane using the splitter separator bar and this is the behavior of the SizeChanged event. Please use the “OnResizeStop” event for your requirement as we told in the last update.
