    <p>The default style for the row header should already be defined when you build your <code>DataGridView</code>. So I would use:</p> <pre><code>if ( /*I want to change this row */) { DataGridViewCellStyle rowStyle; // = Grid.RowHeadersDefaultCellStyle; rowStyle = Grid.Rows[i].HeaderCell.Style; rowStyle.BackColor = Color.Wheat; Grid.Rows[i].HeaderCell.Style = rowStyle; } </code></pre> <p>This way you fill your <code>rowStyle</code> with the predefined style and then change only the part you want to change. See if this solves your problem.</p> <p>//EDIT As you wish to keep the other stylings of the default Windows DataGridView, you would also need to set more of the other parameters of the style. See <a href="http://www.codeproject.com/Questions/164629/How-to-change-only-DataGridView-RowHeader-s-Grid-C" rel="nofollow noreferrer">this post.</a></p> <p>Or try this. When initialiazing:</p> <pre><code> dataGridView1.CellPainting += new DataGridViewCellPaintingEventHandler (dataGridView_CellPainting); </code></pre> <p>Then create the handler function with something like:</p> <pre><code> void dataGridView_CellPainting(object sender, DataGridViewCellPaintingEventArgs e) { DataGridView dv = sender as DataGridView; DataGridViewCellStyle rowStyle;// = dv.RowHeadersDefaultCellStyle; if (e.ColumnIndex == -1) { e.PaintBackground(e.CellBounds, true); e.Handled = true; if (/*I want to change this row */) { rowStyle = dv.Rows[e.RowIndex].HeaderCell.Style; rowStyle.BackColor = Color.Wheat; dv.Rows[e.RowIndex].HeaderCell.Style = rowStyle; using (Brush gridBrush = new SolidBrush(Color.Wheat)) { using (Brush backColorBrush = new SolidBrush(e.CellStyle.BackColor)) { using (Pen gridLinePen = new Pen(gridBrush)) { // Clear cell e.Graphics.FillRectangle(backColorBrush, e.CellBounds); //Bottom line drawing e.Graphics.DrawLine(gridLinePen, e.CellBounds.Left, e.CellBounds.Bottom - 1, e.CellBounds.Right, e.CellBounds.Bottom - 1); // here you force paint of content e.PaintContent(e.ClipBounds); e.Handled = true; } } } } } } </code></pre> <p>This code was based on <a href="https://stackoverflow.com/questions/6041044/how-to-paint-only-datagridviews-cell-background-not-its-content">this post.</a> You would only then need to create more paint conditions for mouseover and selected state. But this should work for you.</p> <p>Remember to remove: <code>Grid.EnableHeadersVisualStyles = false;</code> or force it to: <code>Grid.EnableHeadersVisualStyles = true;</code>.</p>

    1. COThe problem is with turning Grid.EnableHeadersVisualStyles to false. The row headers change to the color, but the column headers are flat and don't look as the did with Grid.EnableHeadersVisualStyles to true. Ive tried your idea for the columns (getting and resetting the style) but its not working ... I will post pictures of what I am talking about

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.
