I am using IGGrid in my iOS app, and I'm using pullDownCell to refresh grid data. The issue is when grid has no data means number of Rows are zero and if I pull grid view to refresh data then grid header hides behind the pullDownCell but if grid has some data then pullDownCell works fine. So why IGGridView header hides behind the pullDownCell when grid is empty? Also, how can I solve this issue?
Hello Karl,
Thank you for contacting Infragistics.
I am not quite sure I know what pullDownCell does since it is not part of the options, events or methods of the igGrid component. Could you please provide an isolated sample that has the issue represented so we can observe the behavior and also could you tell us the version of the product that you have on your side?
Looking forward to hearing from you.

Hello Martin,
Thank you for reply. Please find the attachment. Here is the sample project for pull down cell issue that I have mentioned. You just need to add your IG.framework bundle file and run it and PullDown the grid you can find the issue.
Hello Quest Analytics,
I appologize for the late response. I moved your question under the "Ultimate UI for iOS" product forums, because it was under a different product (Ignite UI for JavaScript). In this forum your question should get a better visibility to the people who can answer you.

Thanks for the sample!So, it does seem like a bug internally in the grid. However, there appears to be a pretty simple workaround. When you have no data, just say there is 1 row, and in the gridView:cellAt: method, return nil. The grid knows how to handle that and won't display anything:
func gridView(_ gridView: IGGridView, cellAt path: IGCellPath) -> IGGridViewCell!{
// if your have no data
return nil;
// else normal cell logic.
}
Hope this helps,
