Problem deleting newly added row from DBG

Hi, There is an exception while deleting newly added row from a databound grid (1.6.1.5 VS.NET 2003/XP or win2k). Steps for reproducing: 1. Start the filter bar grid sample. 2. Go to the last empty row and type in "abc" in CustomerID column, hit tab and enter "abc" as company name. 3. Click on the same row header (without switching the row) and hit delete button. 4. Notice the error "There is no at position 91.". FYI, it works: - If I just type "abc" in company id and then select the row and hit delete key - If I type in abc/abc in company id and company name and then switch to the row above last row (WOLZA), come back to "abc" and then delete the row. Can you please look into this. thanks, - Reddy

Hi, I got 1.6.1.8 version of syncfusion libraries yesterday. I am using Vs.NET 2003/win2k. This bug seems to be fixed in the demo, I reported earlier. But in my code, I still see this problem once in a while (it is randomly failing). Here is the stack trace: catched at Syncfusion.Windows.Forms.Grid.GridDataBoundGrid.EndEdit() in :line 0 System.IndexOutOfRangeException: There is no row at position 1. at System.Data.DataView.GetRecord(Int32 recordIndex) at System.Data.DataView.IsOriginalVersion(Int32 index) at System.Data.DataRowView.SetColumnValue(DataColumn column, Object value) at System.Data.DataColumnPropertyDescriptor.SetValue(Object component, Object value) at Syncfusion.Windows.Forms.Grid.GridModelDataBinder.EndEdit() at Syncfusion.Windows.Forms.Grid.GridDataBoundGrid.EndEdit() thanks, - Reddy

I nailed this bug down. When I am editing in a cell, then try to delete that row, I got the exception. I am now checking if current cell IsEditing, I am calling CurrentCell.EndEdit() and Binder.EndEdit(). It is working fine now. thanks, - Reddy

You may want to try the 2.0.3.0 version which is now available. Are you deleting the row by clicking the header and pressing the delete key? If you are programatically deleting the row, did you try what Reddy suggested above? Are you showing some kind of dialog when you do this? Are you using multiple threads? Can you see this problem in any of our samples so we can see it here?

hi! Thanks for your answer i solve the problem.... in fact, the source code was not very clean! a lot of datatable update (add/del/edit) for nothing!!!! so I simplify the code, and now everything''s ok.... a+ syl
