Error in treegrid after using isFrozen property.

[Wilma Hill]

Hello,

I have faced the issue related to the treegrid when isFrozen property is used to the e-columns.

Error produced when editing after isFrozen=true is done in the treegrid table are:

1.ERROR Error: Cannot read property 'querySelectorAll' of undefined

2.ERROR Error: Cannot read property 'querySelector' of undefined

Here is stackblitz link:

Hi Wilma, 

 

Thanks for contacting Syncfusion Support. 

 

Query#:- Issue while using isFrozen property on Editing. 

 

We are able to replicate the problem at our end while using isFrozen property to columns. To overcome this problem we suggest you to use FrozenColumns API which performs the same functionality of isFrozen property. 

Refer to the code below:- 

App.Component.html 

<ejs-treegrid #treegrid [dataSource]='data' height='400' childMapping='subtasks' [treeColumnIndex]='1' [frozenColumns]='2' [allowSelection]='false' [editSettings]='editSettings' [toolbar]='toolbar'> 

              <e-columns> 

                      <e-column field='taskID' headerText='Task ID' isPrimaryKey='true' width='90' textAlign='Right' 

                             [validationRules]='taskidrules'></e-column> 

                      .    .    . 

              </e-columns> 

 

</ejs-treegrid>
