The function you re looking for is  Insert    It takes as its parameters the index you want to insert at  and an array of values to use for the new row values   Typical usage might include   myDataGridView Rows Insert 4 new object   value1 value2 value3      or something to that effect

If you want to add the row to the end of the grid use the Add   method of the Rows collection     DataGridView1 Rows Add New String   Value1  Value2  Value3     If you want to insert the row at a partiular position use the Insert   method of the Rows collection  as GWLlosa also said      DataGridView1 Rows Insert rowPosition  New String   value1  value2  value3     I know you mentioned you weren t doing databinding  but if you defined a strongly-typed dataset with a single datatable in your project  you could use that and get some nice strongly typed methods to do this stuff rather than rely on the grid methods     DataSet1 DataTable AddRow 1   John Doe   true

I think you should build a dataset datatable in code and bind the grid to that

If your DataGridView is bound to a DataSet  you can not just add a new row in your DataGridView display  It will now work properly   Instead you should add the new row in the DataSet with this code   BindingSource Name  AddNew     This code will also automatically add a new row in your DataGridView display

If you want to use something that is more descriptive than a dumb array without resorting to using a DataSet then the following might prove useful  It still isn t strongly-typed  but at least it is checked by the compiler and will handle being refactored quite well   Dim previousAllowUserToAddRows   dgvHistoricalInfo AllowUserToAddRows dgvHistoricalInfo AllowUserToAddRows   True  Dim newTimeRecord As DataGridViewRow   dgvHistoricalInfo Rows dgvHistoricalInfo NewRowIndex  Clone  With record     newTimeRecord Cells dgvcDate Index  Value    Date     newTimeRecord Cells dgvcHours Index  Value    Hours     newTimeRecord Cells dgvcRemarks Index  Value    Remarks End With  dgvHistoricalInfo Rows Add newTimeRecord   dgvHistoricalInfo AllowUserToAddRows   previousAllowUserToAddRows   It is worth noting that the user must have AllowUserToAddRows permission or this won t work  That is why I store the existing value  set it to true  do my work  and then reset it to how it was
