DataGridViewにTextおよびProgressBarsを設定する

Question

私は各スレッドがDataGridViewの行として表示されるマルチスレッドアプリケーションを作成しています。対応するスレッドの進行状況を示す各行にProgressBarが必要です。

質問は、これは可能ですか？そしてもしそうなら、どうですか？

Answer 1

私はクラスDataGridViewProgressColumn.cs（ソース：MSDN）を加えそれから私は、GridViewコントロール

DataGridViewProgressColumn column = new DataGridViewProgressColumn(); 

kryptonDataGridView1.ColumnCount = 2; 
kryptonDataGridView1.Columns[0].Name = "TESTHeader1"; 
kryptonDataGridView1.Columns[0].AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill; 
kryptonDataGridView1.Columns[1].Name = "TESTHeader22"; 
kryptonDataGridView1.Columns[1].AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill; 
kryptonDataGridView1.Columns.Add(column); 
kryptonDataGridView1.Columns[2].AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill; 
column.HeaderText = "Progress"; 


object[] row1 = new object[] { "test1", "test2", 50 }; 
object[] row2 = new object[] { "test1", "test2", 55 }; 
object[] row3 = new object[] { "test1", "test2", 22 }; 
object[] rows = new object[] { row1, row2, row3 }; 

foreach (object[] row in rows) 
{ 
    kryptonDataGridView1.Rows.Add(row); 
}

<DataGridTemplateColumn Header="Progress" Width="*" Visibility="Visible"> 
    <DataGridTemplateColumn.CellTemplate> 
    <DataTemplate> 
    <StackPanel> 
     <TextBlock Text="{Binding Progress}" HorizontalAlignment="Center" /> 
     <ProgressBar Value="{Binding Path=Progress, Mode=OneWay,UpdateSourceTrigger=PropertyChanged}" Minimum="0" Maximum="100" Height="25" /> 
    </StackPanel> 
</DataTemplate>
