Unable to Close Popup in Self-Referential Data Mode

[Tien Pham]

Source Code Used:
I am using the two components from the example for easier tracking:
Syncfusion Blazor Dropdown Tree Example

• The component on the left uses Hierarchical Data.
• The component on the right uses List Data (Self-referential data).

Issue: When using List Data, the popup does not close after selecting an item. I performed the same actions with ​Hierarchical Data​, but the issue did not occur.

Steps to Reproduce:

1. Click the arrow of Electronics to collapse this item.
   
   
2. In the Sports & Fitness category, select the item Team Sports.
   
   
3. The popup remains open and does not close.
   
   
   Syncfusion Version: I encountered this issue in version 28.2.3.

Hi Syncfusion Team,

I have a question about how to download version 29.1.35 without using NuGet. I tried checking the Patches section and other places like https://www.syncfusion.com/support/directtrac/patches, but I couldn’t find version 29.1.35.

Could you please guide me on how to download it?

As shown in the image below, only version 29.1.33 is available for download

Hi Tien,

Syncfusion provides the Essential Studio installers only for the Volume release (v29.1.33) and Service Pack updates and it does not apply for the weekly releases(29.1.35). 

v29.1.35 is the Weekly release version. Weekly release versions are only published in nuget.org and NPM and are not distributed as standalone installers. You can access these versions directly from NuGet or NPM and integrate them into your project without any additional setup installation.

Also, we provide patch support for the release version alone.

To upgrade to any new version (main or service), you must download and install the setup and use the latest Syncfusion components from the installer.

https://www.syncfusion.com/account/downloads/studio/licensed/29.1.33

Refer to the below documentation link to know about the steps for installing the installer.

https://help.syncfusion.com/common/essential-studio/installation/web-installer/how-to-download

Installation steps - https://help.syncfusion.com/common/essential-studio/installation/web-installer/how-to-install

If you use Syncfusion components from NuGet packages(nuget.org), or if you're upgrading the NuGet packages from one major version to another, such as from v28.* to v29.* you should generate and register the corresponding version and product license key in your projects to prevent trial license warnings.

Syncfusion license keys are major version and product-specific and the generated license key is just a string that needs to be registered before any Syncfusion control is initiated.  Please generate and register the corresponding version and product license key in your projects to prevent trial license warnings.

Also, ensure that all the referenced Syncfusion assemblies\NuGet packages are on the same version as the license key’s version in your project.

Refer to this link for generating license key,

https://help.syncfusion.com/common/essential-studio/licensing/how-to-generate

Refer to this link for registering license key,

https://help.syncfusion.com/common/essential-studio/licensing/how-to-register-in-an-application

Refer to the below KB article to know which version license key should be used in the application,

Hi  Leo Lavanya Dhanaraj,

Thank you for your information.

Because security concerns, we do not register key directly in our source code. Instead of that we download package from Essential Studio and upload it to our internal package feed.

We are following approach in this KB
https://support.syncfusion.com/kb/article/14894/how-to-register-syncfusion-license-securely-in-blazor-wasm-app

So can we download the package 29.1.35 from public nuget feed to our internal feed? Does it have any conflict with other 29.1.3 packages? 

Regards,

Hung Le
