How to: Programmatically Change Formatting in Worksheet Rows Containing Selected Cells

Article

You can change the font of an entire row that contains a selected cell so that the text is bold.

Applies to: The information in this topic applies to document-level projects and application-level projects for Excel 2013 and Excel 2010. For more information, see Features Available by Office Application and Project Type.

To make the current row bold and the previously bolded row normal

Declare a static variable to keep track of the previously selected row.
```
Static previousRow As Integer = 0
```
```
static int previousRow = 0;
```

Retrieve a reference to the current cell using the ActiveCell property.

Dim currentCell As Excel.Range = Me.Application.ActiveCell

Excel.Range currentCell = this.Application.ActiveCell;

Style the current row bold using the EntireRow property of the active cell.

currentCell.EntireRow.Font.Bold = True

currentCell.EntireRow.Font.Bold = true;

Ensure that the current value of previousRow is not 0. A 0 (zero) indicates that this is the first time through this code.
```
If previousRow <> 0 Then
```
```
if (previousRow != 0)
```

Ensure that the current row is different from the previous row.

If currentCell.Row <> previousRow Then

if (currentCell.Row != previousRow)

Retrieve a reference to a range that represents the row that was previously selected, and set that row to not be bold.

Dim rng As Excel.Range = DirectCast(ws.Rows(previousRow), Excel.Range)
rng.EntireRow.Font.Bold = False

Excel.Range rng = (Excel.Range)ws.Rows[previousRow];
rng.EntireRow.Font.Bold = false;

Store the current row so that it can become the previous row on the next pass.
```
previousRow = currentCell.Row
```
```
previousRow = currentCell.Row;
```

The following example shows the complete method.

Example

Private Sub BoldCurrentRow(ByVal ws As Excel.Worksheet)

    ' Keep track of the previously bolded row. 
    Static previousRow As Integer = 0

    ' Work with the current active cell. 
    Dim currentCell As Excel.Range = Me.Application.ActiveCell

    ' Bold the current row.
    currentCell.EntireRow.Font.Bold = True 

    ' If a pass has been done previously, make the old row not bold. 
    ' Make sure previousRow is not 0 (otherwise this is your first pass through). 
    If previousRow <> 0 Then 

        ' Make sure the current row is not the same as the previous row. 
        If currentCell.Row <> previousRow Then 

            Dim rng As Excel.Range = DirectCast(ws.Rows(previousRow), Excel.Range)
            rng.EntireRow.Font.Bold = False 
        End If 
    End If 

    ' Store the new row number for the next pass.
    previousRow = currentCell.Row
End Sub

// Keep track of the previously bolded row. 
static int previousRow = 0;

private void BoldCurrentRow(Excel.Worksheet ws)
{
    // Work with the current active cell.
    Excel.Range currentCell = this.Application.ActiveCell;

    // Bold the current row.
    currentCell.EntireRow.Font.Bold = true; 

    // If a pass has been done previously, make the old row not bold. 
    // Make sure previousRow is not 0 (otherwise this is your first pass through). 
    if (previousRow != 0)

        // Make sure the current row is not the same as the previous row. 
        if (currentCell.Row != previousRow)
        {
            Excel.Range rng = (Excel.Range)ws.Rows[previousRow];
            rng.EntireRow.Font.Bold = false;
        }

    // Store the new row number for the next pass.
    previousRow = currentCell.Row;
}
