RowSelected and RowDeselected in TreeGrid when using AutoCheckHierarchy and ShowCheckbox

1. I saw that RowSelected and Deselected are triggered when the Checkbox is selected, does not matter if is a parent or child but when you select a row for the second time on the same page, the RowDeselected is triggered before the RowSelected event. And when you deselect a row the RowDeselect is triggered first but the args data is the last selected one-row data and no the deselected one, after the RowSelected es executed with the deselected row data as args.data.
I tried with CheckboxChange but this only returns the Index or Indexes but not the data and the GetRowByIndex is deprecated.
I add a sample code to reproduce the bug.
2. Is there a method to get all the selectedCheckRows? the GetCheckedRecords(), gets the checked records on the current page of the grid

Hi Adriana,    
    
Thanks for contacting syncfusion forum. 
 

Query1 : RowSelected and RowDeselected in TreeGrid when using AutoCheckHierarchy and ShowCheckbox


Based on your query, you are using the checkbox column feature. The rowselection and checkbox column(showcheckbox property and autohierarchy property) are different.  Checkbox column is only used for selecting the records hierarchically. If a checkbox is checked, it does not indicate that the respective row is selected. 
 
So, the RowSelected and RowDeselected events are invoked based on the status of the highlighted rows (i.e. selected rows) not based on the selected checkboxes. 
 
Please refer to the below documentations for more details: 
 
 
 
If you want to select the row based on checkbox and row selection event, we suggest you to use the checkbox selection feature. 
 
Please refer to the below demo and documentation:

Thanks for the answer your suggestion to use the checkbox selection feature, when I select a parent does not select the children that is why I am using the showcheckbox property and autohierarchy property, and also the position of a checkbox, when is a parent and when is a child, I saw that ChechboxChange is an event triggered when I select the checkbox, I can know if was selected or deselected, because args has RowIndex but I cant get the data by args. Any other Suggestion?

Hi Adriana,   
 
Thanks for the update. 
 

Query:   I saw that ChechboxChange is an event triggered when I select the checkbox, I can know if was selected or deselected, because args has RowIndex but I cant get the data by args. Any other Suggestion? 

Based on your query, We suggest that you use  the GetCurrentViewRecords method. You can get the selected data using the GetCurrentViewRecords method with the selected row indexes.

Please refer to the below code snippet,

 
<SfTreeGrid @ref="treeGrid" …> 
             <TreeGridEvents CheckboxChange="chekboxchange" TValue="WrapData"></TreeGridEvents> 
….. 
                </SfTreeGrid> 
…. 
 
    protected void chekboxchange(CheckBoxChangeEventArgs<WrapData> args) 
        { 
            var index =args.SelectedRowIndex; 
            var data = this.treeGrid.GetCurrentViewRecords()[Convert.ToInt32(index)]; 
            Console.WriteLine(data); 
 
 
        } 

Please refer to the below screenshot: 
 
 
Please refer to the below sample, 
 
Please refer to the below API documentation:
