[RESOLVED] DataGridView Bold One Row

How can I modify this:

vb Code:

Content.Font = New Font("Verdana", 8, FontStyle.Bold)

So that in my datagridview it only makes the selected row bold when it is double clicked?

Whole Thing:

vb Code:

Private Sub Content_CellContentClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles Content.CellDoubleClick
        row = e.RowIndex
        If row >= 0 Then
            Content.Font = New Font("Verdana", 8, FontStyle.Bold)
        End If
    End Sub

Thanks!

You will have to set that individual row's DefaultCellStyle, like so:

vb.net Code:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim BoldRow As New DataGridViewCellStyle With {.Font = New System.Drawing.Font("Verdana", 8.0!, FontStyle.Bold)}
        Me.DataGridView1.Rows(rowindex).DefaultCellStyle = BoldRow
    End Sub

Kool that works!

Now when I change rows by double clicking the previously bolded row stays bold, why is that?

vb.net Code:

Content.Font = New Font("Verdana", 8, FontStyle.Regular) ' I was expecting this row to make them all normal font...
Dim BoldRow As New DataGridViewCellStyle With {.Font = New System.Drawing.Font("Verdana", 8.0!, FontStyle.Bold)}
Content.Rows(row).DefaultCellStyle = BoldRow

It's because that row is no longer pointing to the DataGridView.RowsDefaultCellStyle anymore. You have given it a new custom CellStyle. So, you will have to reset the rows where you have given it a custom font to the DataGridView.RowsDefaultCellStyle again (or a new CellStyle, whichever suits your needs).

This is what I would do. Everytime you bold a row, add it to a class level variable called bolded rows. Then when you want to unbold those rows, you loop through that list and change their CellStyle. Like so:

vb.net Code:

Public Class Form1
    Private BoldedRows As New List(Of DataGridViewRow)
 
    Private Sub DataGridView1_CellDoubleClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellDoubleClick
        Me.DataGridView1.Rows(e.RowIndex).DefaultCellStyle = New DataGridViewCellStyle With {.Font = New Drawing.Font("Verdana", 8.0!, FontStyle.Bold)}
        Me.BoldedRows.Add(Me.DataGridView1.Rows(e.RowIndex))
    End Sub
 
    Public Sub ResetBoldedRows()
        For Each BoldRow As DataGridViewRow In Me.BoldedRows
            Me.DataGridView1.Rows(Me.DataGridView1.Rows.IndexOf(BoldRow)).DefaultCellStyle = Me.DataGridView1.RowsDefaultCellStyle
        Next
        Me.BoldedRows.Clear()
    End Sub
 
    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        ResetBoldedRows()
    End Sub
End Class

Nice Thanks!
