DataGridViewCellFormattingEventArgs.RowIndex DataGridViewCellFormattingEventArgs.RowIndex DataGridViewCellFormattingEventArgs.RowIndex DataGridViewCellFormattingEventArgs.RowIndex Property

定義

書式指定するセルの行インデックスを取得します。Gets the row index of the cell that is being formatted.

public:
 property int RowIndex { int get(); };
public int RowIndex { get; }
member this.RowIndex : int
Public ReadOnly Property RowIndex As Integer

プロパティ値

書式指定するセルの行インデックス。The row index of the cell that is being formatted.

次のコード例は、 RowIndexプロパティを使用して、書式設定されているセルを取得する方法を示しています。The following code example demonstrates how to use the RowIndex property to retrieve the cell being formatted. 次に、セル参照を使用して、セルのツールヒントテキストを設定します。The cell reference is then used to set the cell's ToolTip text.

// Sets the ToolTip text for cells in the Rating column.
void dataGridView1_CellFormatting(Object^ /*sender*/, 
    DataGridViewCellFormattingEventArgs^ e)
{
    if ( (e->ColumnIndex == this->dataGridView1->Columns["Rating"]->Index)
        && e->Value != nullptr )
    {
        DataGridViewCell^ cell = 
            this->dataGridView1->Rows[e->RowIndex]->Cells[e->ColumnIndex];
        if (e->Value->Equals("*"))
        {                
            cell->ToolTipText = "very bad";
        }
        else if (e->Value->Equals("**"))
        {
            cell->ToolTipText = "bad";
        }
        else if (e->Value->Equals("***"))
        {
            cell->ToolTipText = "good";
        }
        else if (e->Value->Equals("****"))
        {
            cell->ToolTipText = "very good";
        }
    }
}
// Sets the ToolTip text for cells in the Rating column.
void dataGridView1_CellFormatting(object sender, 
    DataGridViewCellFormattingEventArgs e)
{
    if ( (e.ColumnIndex == this.dataGridView1.Columns["Rating"].Index)
        && e.Value != null )
    {
        DataGridViewCell cell = 
            this.dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex];
        if (e.Value.Equals("*"))
        {                
            cell.ToolTipText = "very bad";
        }
        else if (e.Value.Equals("**"))
        {
            cell.ToolTipText = "bad";
        }
        else if (e.Value.Equals("***"))
        {
            cell.ToolTipText = "good";
        }
        else if (e.Value.Equals("****"))
        {
            cell.ToolTipText = "very good";
        }
    }
}
' Sets the ToolTip text for cells in the Rating column.
Sub dataGridView1_CellFormatting(ByVal sender As Object, _
    ByVal e As DataGridViewCellFormattingEventArgs) _
    Handles dataGridView1.CellFormatting

    If e.ColumnIndex = Me.dataGridView1.Columns("Rating").Index _
        AndAlso (e.Value IsNot Nothing) Then

        With Me.dataGridView1.Rows(e.RowIndex).Cells(e.ColumnIndex)

            If e.Value.Equals("*") Then
                .ToolTipText = "very bad"
            ElseIf e.Value.Equals("**") Then
                .ToolTipText = "bad"
            ElseIf e.Value.Equals("***") Then
                .ToolTipText = "good"
            ElseIf e.Value.Equals("****") Then
                .ToolTipText = "very good"
            End If

        End With

    End If

End Sub 'dataGridView1_CellFormatting
