I have some trouble with setting the last row in my datagridview selected. I select the last row this way: <pre><code>if (grid.Rows.Count > 0) { try { grid.Rows[grid.Rows.Count - 1].Selected = true; grid.CurrentCell = grid.Rows[grid.Rows.Count - 1].Cells[1] } catch (IndexOutOfRangeException) { } catch (ArgumentOutOfRangeException) { } } </code></pre> When I execute this code I get an exception: <code>IndexOutOfRangeException occurred</code>: Index-1 does not have a value. When I debug the <code>Rows</code>collection and the corresponding <code>Cells</code> collection I see both collections are filled. The index also exists of the Rows and Cells collection. I have no clue what I am doing wrong here. Someone who can help me out here? Thnx EDIT: Here is the complete exception: <pre><code>System.IndexOutOfRangeException: Index -1 does not have a value. at System.Windows.Forms.CurrencyManager.get_Item(Int32 index) at System.Windows.Forms.CurrencyManager.get_Current() at System.Windows.Forms.DataGridView.DataGridViewDataConnection.OnRowEnter(DataGridViewCellEventArgs e) at System.Windows.Forms.DataGridView.OnRowEnter(DataGridViewCell& dataGridViewCell, Int32 columnIndex, Int32 rowIndex, Boolean canCreateNewRow, Boolean validationFailureOccurred) at System.Windows.Forms.DataGridView.SetCurrentCellAddressCore(Int32 columnIndex, Int32 rowIndex, Boolean setAnchorCellAddress, Boolean validateCurrentCell, Boolean throughMouseClick) at System.Windows.Forms.DataGridView.set_CurrentCell(DataGridViewCell value) </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
