DataGridView - how to delete Row

Question

Hi all I am working on C# project using C# 2.0. I have a DataGrid that contains 10 rows and at runtime I insert one more row at DataGridView.Insert(01); in my next step I want to delete the row from DataGridView at DataGridView.RemoveAt(9) // Index 9 is the last row in the grid. But I am not able to delete the row. I am getting following exception: System.InvalidOperationException:Uncommitted new row cannot be deleted. at System.Windows.Forms.DataGridViewRowCollection.RemoveAt(Int32 index) Please help if you know the solution. Thanks in advance for your help.

Well the exception sounds as though you're trying to delete the row used for adding new data at the bottom of the grid. However that makes no sense because if you started with 10 rows (including the 'new' row) and then inserted another row at index 0 at runtime you'll have 11 rows and the 10th (with an index of 9) will be the last one with any data in it. It should therefore be deletable. Possibly therefore you didn't in fact have 10 rows to start with or the Rows collection is not getting updated for some reason. You can always check whether a row is a 'new' row or not before attempting to delete it by using the DataGridViewRow.IsNewRow property. You could therefore try a different approach: if (dataGridView1.Rows[9].IsNewRow) dataGridview1.Rows.RemoveAt[8]; else dataGridview1.Rows.RemoveAt[9];

Not sure if it helps but search: http://www.sourcepop.com/GetResults.aspx?q=delete%20row%20datagridview There are a whole bunch of tutorial links there for the datagrid add edit delete etc. You can compare your code to this and should find some answers I think.
