DataGridView.AutoResizeRow Method

Definition

Namespace:

System.Windows.Forms

Assembly:

System.Windows.Forms.dll

Adjusts the height of the specified row to fit the contents of its cells.

Overloads

AutoResizeRow(Int32)	Adjusts the height of the specified row to fit the contents of all its cells including the header cell.
AutoResizeRow(Int32, DataGridViewAutoSizeRowMode)	Adjusts the height of the specified row using the specified size mode.
AutoResizeRow(Int32, DataGridViewAutoSizeRowMode, Boolean)	Adjusts the height of the specified row using the specified size mode, optionally calculating the height with the expectation that column widths will subsequently be adjusted.

AutoResizeRow(Int32)

Adjusts the height of the specified row to fit the contents of all its cells including the header cell.

public:
 void AutoResizeRow(int rowIndex);

public void AutoResizeRow (int rowIndex);

member this.AutoResizeRow : int -> unit

Public Sub AutoResizeRow (rowIndex As Integer)

Parameters

rowIndex

Int32

The index of the row to resize.

Exceptions

ArgumentOutOfRangeException

rowIndex is not in the valid range of 0 to the number of rows minus 1.

Examples

The following code example resizes the third row in a DataGridView to fit the column contents. 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 SizeThirdRow( Object^ /*sender*/, EventArgs^ /*e*/ )
{
   dataGridView1->AutoResizeRow(2, DataGridViewAutoSizeRowMode::AllCellsExceptHeader);
}

private void SizeThirdRow(Object sender, EventArgs e)
{
    dataGridView1.AutoResizeRow(
        2, DataGridViewAutoSizeRowMode.AllCellsExceptHeader);
}

Private Sub SizeThirdRow(ByVal sender As Object, _
    ByVal e As System.EventArgs) Handles Button7.Click

    Dim thirdRow As Integer = 2
    DataGridView1.AutoResizeRow( _
        2, DataGridViewAutoSizeRowMode.AllCellsExceptHeader)

End Sub

Remarks

This method is useful if you want to control when a row resizes. The row height is adjusted only once per method call; if the contents of the row later change, the row will not automatically adjust. To resize all rows, use the AutoResizeRows method. To set the row to automatically resize whenever its 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.

AutoResizeRow(Int32, DataGridViewAutoSizeRowMode)

Adjusts the height of the specified row using the specified size mode.

public:
 void AutoResizeRow(int rowIndex, System::Windows::Forms::DataGridViewAutoSizeRowMode autoSizeRowMode);

public void AutoResizeRow (int rowIndex, System.Windows.Forms.DataGridViewAutoSizeRowMode autoSizeRowMode);

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

Public Sub AutoResizeRow (rowIndex As Integer, autoSizeRowMode As DataGridViewAutoSizeRowMode)

Parameters

rowIndex

Int32

The index of the row to resize.

autoSizeRowMode

DataGridViewAutoSizeRowMode

One of the DataGridViewAutoSizeRowMode values.

Exceptions

InvalidOperationException

autoSizeRowMode has the value RowHeader and RowHeadersVisible is false.

InvalidEnumArgumentException

autoSizeRowMode is not a valid DataGridViewAutoSizeRowMode value.

ArgumentOutOfRangeException

rowIndex is not in the valid range of 0 to the number of rows minus 1.

    Dim thirdRow As Integer = 2

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 height 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.

AutoResizeRow(Int32, DataGridViewAutoSizeRowMode, Boolean)

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

protected:
 void AutoResizeRow(int rowIndex, System::Windows::Forms::DataGridViewAutoSizeRowMode autoSizeRowMode, bool fixedWidth);

protected void AutoResizeRow (int rowIndex, System.Windows.Forms.DataGridViewAutoSizeRowMode autoSizeRowMode, bool fixedWidth);

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

Protected Sub AutoResizeRow (rowIndex As Integer, autoSizeRowMode As DataGridViewAutoSizeRowMode, fixedWidth As Boolean)

Parameters

rowIndex

Int32

The index of the row to resize.

autoSizeRowMode

DataGridViewAutoSizeRowMode

One of the DataGridViewAutoSizeRowMode values.

fixedWidth

Boolean

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

Exceptions

InvalidOperationException

autoSizeRowMode has the value RowHeader and RowHeadersVisible is false.

InvalidEnumArgumentException

autoSizeRowMode is not a valid DataGridViewAutoSizeRowMode value.

ArgumentOutOfRangeException

rowIndex is not in the valid range of 0 to the number of rows minus 1.

This overload lets you specify a sizing mode that calculates the new height 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 fixedWidth is false, the row height will be calculated with the expectation that you will call the AutoResizeColumn or AutoResizeColumns method next.
