 void AutoResizeRowHeadersWidth(System::Windows::Forms::DataGridViewRowHeadersWidthSizeMode rowHeadersWidthSizeMode);

public void AutoResizeRowHeadersWidth(System.Windows.Forms.DataGridViewRowHeadersWidthSizeMode rowHeadersWidthSizeMode);

member this.AutoResizeRowHeadersWidth : System.Windows.Forms.DataGridViewRowHeadersWidthSizeMode -> unit

Public Sub AutoResizeRowHeadersWidth (rowHeadersWidthSizeMode As DataGridViewRowHeadersWidthSizeMode)

Parameters

Exceptions

Remarks

This method is useful if you want to control when the row headers resize. The width of the row headers is adjusted only once per method call; if the contents of the row headers later change, the row headers will not automatically adjust. To set the row headers to automatically resize when their contents change, use the RowHeadersWidthSizeMode property.

This method lets you specify a sizing mode that calculates the new width based on values in a limited set of headers, such as those in displayed rows only. This improves performance when the control contains a large number of rows.

Examples

The following code example illustrates how to resize the row header widths based on changes to the contents of the first row header. This code example is part of a larger example provided in How to: Programmatically Resize Cells to Fit Content in the Windows Forms DataGridView Control.

void SizeFirstRowHeaderToAllHeaders( Object^ /*sender*/, EventArgs^ /*e*/ )
{
   dataGridView1->AutoResizeRowHeadersWidth(0, DataGridViewRowHeadersWidthSizeMode::AutoSizeToAllHeaders);
}

private void SizeFirstRowHeaderToAllHeaders(Object sender, EventArgs e)
{
    dataGridView1.AutoResizeRowHeadersWidth(
        0, DataGridViewRowHeadersWidthSizeMode.AutoSizeToAllHeaders);
}

Private Sub SizeFirstRowHeaderToAllHeaders(ByVal sender As Object, _
    ByVal e As System.EventArgs) Handles Button8.Click

    DataGridView1.AutoResizeRowHeadersWidth( _
        DataGridViewRowHeadersWidthSizeMode.AutoSizeToAllHeaders)

End Sub

Remarks

This method is useful if you want to control when the row headers resize if only the contents of the header in the specified row have changed as a result of user edits or changes to a bound data source. The width of the row headers is adjusted only once per method call if the content change requires it; if the contents of the row headers later change, the row headers will not automatically adjust. To set the row headers to automatically resize when their contents change, use the RowHeadersWidthSizeMode property.

This method lets you specify a sizing mode that calculates the new width based on values in a limited set of headers, such as those in displayed rows only. This improves performance when the control contains a large number of rows.

This overload is protected and is designed to enable you to achieve ideal cell height-to-width ratios in a derived DataGridView class. If the fixedColumnHeadersHeight or fixedRowsHeight parameters are false, the width of the row headers will be calculated with the expectation that you will call methods such as AutoResizeRows and AutoResizeColumnHeadersHeight next.
