TreeGrid Guid? as IdMapping and ParentIdMapping

Hello,

should a TreeGrid support a nullable Guid as IdMapping and ParentIdMapping? If so, in my case the whole GUI hangs in the session as soon as a list with a corresponding model is bound as the DataSource. Only refresh via F5 then helps.

Hi

 I think I have found some kind of issues related to using Guids as Id's in the TreeGrid. I downloaded your sample and modified it a bit to reproduce the error. 

 The issue I found is when you try to add a new item at the toplevel. Have attached a zipfile with an short description of the errors (Treegrid - Guids.docx) and two videos describing the errors I have described in the word file and the source code (your Sample-656747257) but updated .

Query 2: Could not edit and updated the newly added record 
 
For performing CRUD functionalities properly, we need to set one of the column as “Primary key” column. Please check the below help documentation, 
 
In your sample, you have not set the primary key for any column. We suggest you to set IsPrimaryKey property to true for GUID column in order to resolve the reported issue. 
 
Please check the below code snippet, 
 
 
 
<SfTreeGrid DataSource="@TreeDataSource" IdMapping="Id" ParentIdMapping="ParentId" TreeColumnIndex="1" 
            Toolbar="@(new List<string>() {"Add", "Edit", "Delete", "Update", "Cancel"})"> 
                        IsPrimaryKey="true" 
                        Width="80" 
                        TextAlign="TextAlign.Left" /> 
        ------ 
    </TreeGridColumns> 
</SfTreeGrid> 
 
 
NOTE: Field value should be unique value. 
 
Kindly get back to us for further assistance.

Hi 

Thanks for your help. 

To set the IsPrimary to true solves the problem. 

Thanks!
