Hey - I've attached a sample project to explain this a little better, but essentially what I'm having an issue with is when the grid goes out and does a LoadMore rows, the SectionHeaderView is being redrawn but then when I scroll back up it remains in the middle of the grid.
I was wondering what you think I'm doing wrong.
Hi,
That is strange. From what i can tell, it appears to be a timing issue. As a workaround, if you call UpdateData in a beginInvoke call, it gives the section header enough time to update. I've updated a code snippet below and my changes are in bold.
public override void LoadMoreRows (IGGridViewDataSourceHelper dataSource) { mClinicNavigatorViewController.mPage++; if (mClinicNavigatorViewController.lstGridItems.Count > 0) { mClinicNavigatorViewController.lstGridItems.InsertRange (mClinicNavigatorViewController.lstGridItems.Count, LoadMorePendingDocuments ()); //Rebind the datasource dataSource.Data = mClinicNavigatorViewController.lstGridItems.ToArray (); //Update the display this.BeginInvokeOnMainThread (() => { gridView.UpdateData (); }); } }
Let me know if that helps.
