RefreshAsync() on SfTreeGrid throws an Error

[John Johnson]

Hi all,

I am getting an Object not set to an instance of an object error when I am invoking the RefreshAsync() on SfTreeGrid object.

What could be the issue?

<SfButton OnClick="Refresh" Content="Refresh data"></SfButton>

<SfTreeGrid @ref="sfTreeGrid">

   Some fields here

</SfTreeGrid>

@code {

SfTreeGrid<DataObject> sfTreeGrid = new SfTreeGrid<DataObject>();

private async Task Refresh() 
{

 await this.sfTreeGrid.RefreshAsync();   <---- here gets the error thrown.

}
