Cell appearance not updated after deleting rows
posted
I have a problem deleting rows that have a cell with an image and a tooltiptext. For example:
row1, cell1 has icon and tooltip
row2, cell1 has icon and tooltip
row3, cell1 has no icon and tooltip
row4, cell1 has icon and tooltip

after I delete the row2, the next happens
row1, cell1 has icon and tooltip
row3, cell1 has the icon and tooltip of row4
row4, cell1 has no icon neither tooltip

IMO it seems what's happening is that the datasource and the grid are updated when a row is deleted, but the datasource (?) of the appearance and tooltip not. Here some source code of a failed test (assuming the row I want to delete is in band 1):

UltraGridRow parent = row.ParentRow; //just to select the parent after deleting the row
poolGrid.ActiveRow = null; //remove any reference to active row so after deleting the row there won't be any permanently selected row (grid bug)
row.Selected = false; //the same as the previous line
row.Hidden = true; //test, failed
poolGrid.SuspendLayout(); //test, failed
row.Delete(false);
poolGrid.ResumeLayout(); //test, failed, paired with suspendlayout
parent.Selected = true; //select parent

     How are you applying the Appearance to the row? Usually, the best and most efficient way to apply any row-level settings like a tooltip or an appearance is to use the InitializeRow event. 

     If that's not helpful, then I recommend you make sure you get the latest Hot Fix. This might be a bug that has already been fixed. 

    If that doesn't help, then you should Submit an incident to Infragistics Developer Support an, if possible, include a small sample project demonstrating the problem so they can check it out.
