    <p>I have a <code>DataGridView</code> with a few <code>DataGridViewComboBoxColumn</code>'s where the actual value is tied to an ID but the <code>DisplayMember</code> is the string counterpart in a lookup table. I'm trying to make it so when I sort by that column then the sort is done based on the <code>DisplayMember</code>, not the <code>ValueMember</code>. I know this was addressed in <a href="https://stackoverflow.com/q/2895849/371184">this question</a> but the answer was less than in depth nor did I understand it.</p> <p>What I've tried thus far</p> <ul> <li>Binding to the <code>SortCompare</code> event but discovered it isn't fired on a databound column.</li> <li>Manually sorting on the <code>ColumnHeaderMouseClick</code> event but rows in a <code>DataGridViewRowCollection</code> are read-only and I can't programatically insert rows (while swapping) on a databound collection.</li> <li>Creating a hidden <code>DataGridViewTextBoxColumn</code> where the cells are automatically set to the <code>DisplayMember</code> of the original column then attempting to sort that column instead. However, a databound collection cannot be sorted based on an unbounded column.</li> </ul> <p><strong>Edit:</strong> To further clarify: I'm attempting to sort the entire <code>DataGridView</code> based on the <code>DisplayMember</code> of the comboboxes, not sort the comboboxes themselves.</p> <p>How can I sort a <code>DataGridView</code> based on the <code>DisplayMember</code> of a databound <code>DataGridViewComboBoxColumn</code>?</p>

    2. COMaybe? I know the SQL statement I'd have to use but I'm not sure how to invoke SQL directly on the DataGridView.

    3. COare you not binding your dgv with a datatable or so? In that case how are you populating datatable? I guess you are getting the values from underlying db, aint so?

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.
