 int GetColumnsWidth(System::Windows::Forms::DataGridViewElementStates includeFilter);
public int GetColumnsWidth(System.Windows.Forms.DataGridViewElementStates includeFilter);
member this.GetColumnsWidth : System.Windows.Forms.DataGridViewElementStates -> int
Public Function GetColumnsWidth (includeFilter As DataGridViewElementStates) As Integer

Parameters

includeFilter
DataGridViewElementStates

Een bitsgewijze combinatie van de DataGridViewElementStates waarden die het filter vertegenwoordigen voor opname.

Retouren

Int32

De breedte, in pixels, die nodig is om alle kolommen weer te geven die voldoen aan de filtervereisten.

Uitzonderingen

ArgumentException

includeFilter is geen geldige bitsgewijze combinatie van DataGridViewElementStates waarden.

Voorbeelden

Het volgende codevoorbeeld illustreert het gebruik van deze methode. Dit voorbeeld maakt deel uit van een groter voorbeeld dat beschikbaar is in Hoe to: Het uiterlijk van rijen aanpassen in het Windows Forms DataGridView-besturingselement.

// Paints the custom selection background for selected rows.
void dataGridView1_RowPrePaint(object sender,
        DataGridViewRowPrePaintEventArgs e)
{
    // Do not automatically paint the focus rectangle.
    e.PaintParts &= ~DataGridViewPaintParts.Focus;

    // Determine whether the cell should be painted
    // with the custom selection background.
    if ((e.State & DataGridViewElementStates.Selected) ==
                DataGridViewElementStates.Selected)
    {
        // Calculate the bounds of the row.
        Rectangle rowBounds = new Rectangle(
            this.dataGridView1.RowHeadersWidth, e.RowBounds.Top,
            this.dataGridView1.Columns.GetColumnsWidth(
                DataGridViewElementStates.Visible) -
            this.dataGridView1.HorizontalScrollingOffset + 1,
            e.RowBounds.Height);

        // Paint the custom selection background.
