DataGridView.AutoResizeRows Method

Definition

Namespace:

System.Windows.Forms

Assembly:

System.Windows.Forms.dll

Adjusts the heights of some or all rows to fit their contents.

Overloads

AutoResizeRows(DataGridViewAutoSizeRowsMode)	Adjusts the heights of the rows using the specified size mode value.
AutoResizeRows(Int32, Int32, DataGridViewAutoSizeRowMode, Boolean)	Adjusts the heights of the specified rows using the specified size mode, optionally calculating the heights with the expectation that column widths will subsequently be adjusted.
AutoResizeRows()	Adjusts the heights of all rows to fit the contents of all their cells, including the header cells.
AutoResizeRows(DataGridViewAutoSizeRowsMode, Boolean)	Adjusts the heights of all rows using the specified size mode, optionally calculating the heights with the expectation that column widths will subsequently be adjusted.

AutoResizeRows(DataGridViewAutoSizeRowsMode)

Adjusts the heights of the rows using the specified size mode value.

public:
 void AutoResizeRows(System::Windows::Forms::DataGridViewAutoSizeRowsMode autoSizeRowsMode);

public void AutoResizeRows (System.Windows.Forms.DataGridViewAutoSizeRowsMode autoSizeRowsMode);

member this.AutoResizeRows : System.Windows.Forms.DataGridViewAutoSizeRowsMode -> unit

Public Sub AutoResizeRows (autoSizeRowsMode As DataGridViewAutoSizeRowsMode)

Parameters

autoSizeRowsMode

DataGridViewAutoSizeRowsMode

One of the DataGridViewAutoSizeRowsMode values.

Exceptions

InvalidOperationException

autoSizeRowsMode has the value AllHeaders or DisplayedHeaders, and RowHeadersVisible is false.

InvalidEnumArgumentException

autoSizeRowsMode is not a valid DataGridViewAutoSizeRowsMode value.

ArgumentException

autoSizeRowsMode has the value None.

Examples

The following code example demonstrates how to resize all rows based on non-header cell content. 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 SizeAllRows( Object^ /*sender*/, EventArgs^ /*e*/ )
{
   dataGridView1->AutoResizeRows(DataGridViewAutoSizeRowsMode::AllCellsExceptHeaders);
}

private void SizeAllRows(Object sender,
    EventArgs e)
{
    dataGridView1.AutoResizeRows(
        DataGridViewAutoSizeRowsMode.AllCellsExceptHeaders);
}

Private Sub SizeAllRows(ByVal sender As Object, _
    ByVal e As System.EventArgs) Handles Button11.Click

    DataGridView1.AutoResizeRows(DataGridViewAutoSizeRowsMode.AllCellsExceptHeaders)

End Sub

Remarks

This method is useful if you want to control when rows resize. The row heights are adjusted only once per method call; if the contents of the rows later change, the rows will not automatically adjust. To resize a specific row, use the AutoResizeRow method. To resize a subset of rows, use the AutoResizeRows(Int32, Int32, DataGridViewAutoSizeRowMode, Boolean) overload. To set the rows to automatically resize whenever their contents change, use the AutoSizeRowsMode property.

For cell contents to wrap onto multiple lines when a row is resized, the cell style in effect for the cell must have a WrapMode property value of True.

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

AutoResizeRows(Int32, Int32, DataGridViewAutoSizeRowMode, Boolean)

Adjusts the heights of the specified rows using the specified size mode, optionally calculating the heights with the expectation that column widths will subsequently be adjusted.

protected:
 void AutoResizeRows(int rowIndexStart, int rowsCount, System::Windows::Forms::DataGridViewAutoSizeRowMode autoSizeRowMode, bool fixedWidth);

protected void AutoResizeRows (int rowIndexStart, int rowsCount, System.Windows.Forms.DataGridViewAutoSizeRowMode autoSizeRowMode, bool fixedWidth);

member this.AutoResizeRows : int * int * System.Windows.Forms.DataGridViewAutoSizeRowMode * bool -> unit

Protected Sub AutoResizeRows (rowIndexStart As Integer, rowsCount As Integer, autoSizeRowMode As DataGridViewAutoSizeRowMode, fixedWidth As Boolean)

Parameters

rowIndexStart

Int32

The index of the first row to resize.

rowsCount

Int32

The number of rows to resize.

autoSizeRowMode

DataGridViewAutoSizeRowMode

One of the DataGridViewAutoSizeRowMode values.

fixedWidth

Boolean

true to calculate the new heights based on the current column widths; false to calculate the heights with the expectation that the column widths will also be adjusted.

Exceptions

InvalidOperationException

autoSizeRowsMode has the value AllHeaders or DisplayedHeaders, and RowHeadersVisible is false.

InvalidEnumArgumentException

autoSizeRowsMode is not a valid DataGridViewAutoSizeRowsMode value.

ArgumentException

autoSizeRowsMode has the value None.

ArgumentOutOfRangeException

rowIndexStart is less than 0.

-or-

rowsCount is less than 0.

Remarks

This method is useful if you want to control when rows resize, but you want to resize only a specific subset of rows, such as those within a range of bound records that have been updated. The row heights for the specified rows are adjusted only once per method call; if the contents of the rows later change, the rows will not automatically adjust. To resize a specific row, use the AutoResizeRow method. To resize all rows, use a different overload of the AutoResizeRows method. To set the rows to automatically resize whenever their contents change, use the AutoSizeRowsMode property.

For cell contents to wrap onto multiple lines when a row is resized, the cell style in effect for the cell must have a WrapMode property value of True.

This overload lets you specify a sizing mode that calculates the new heights based on values in a limited set of cells, 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 fixedWidth parameter is false, the row heights will be calculated with the expectation that you will call the AutoResizeColumn or AutoResizeColumns method next.
