I am creating a multi-threaded application in which each thread will appear as a row in my DataGridView
. I want a ProgressBar
in each row indicatin
I added class DataGridViewProgressColumn.cs (source: MSDN)
using System;
using System.Collections.Generic;
using System.Text;
using System.Windows.Forms;
using System.Drawing;
using System.ComponentModel;
namespace Sample
{
public class DataGridViewProgressColumn : DataGridViewImageColumn
{
public DataGridViewProgressColumn()
{
CellTemplate = new DataGridViewProgressCell();
}
}
}
namespace Sample
{
class DataGridViewProgressCell : DataGridViewImageCell
{
// Used to make custom cell consistent with a DataGridViewImageCell
static Image emptyImage;
static DataGridViewProgressCell()
{
emptyImage = new Bitmap(1, 1, System.Drawing.Imaging.PixelFormat.Format32bppArgb);
}
public DataGridViewProgressCell()
{
this.ValueType = typeof(int);
}
// Method required to make the Progress Cell consistent with the default Image Cell.
// The default Image Cell assumes an Image as a value, although the value of the Progress Cell is an int.
protected override object GetFormattedValue(object value,
int rowIndex, ref DataGridViewCellStyle cellStyle,
TypeConverter valueTypeConverter,
TypeConverter formattedValueTypeConverter,
DataGridViewDataErrorContexts context)
{
return emptyImage;
}
protected override void Paint(System.Drawing.Graphics g, System.Drawing.Rectangle clipBounds, System.Drawing.Rectangle cellBounds, int rowIndex, DataGridViewElementStates cellState, object value, object formattedValue, string errorText, DataGridViewCellStyle cellStyle, DataGridViewAdvancedBorderStyle advancedBorderStyle, DataGridViewPaintParts paintParts)
{
try
{
int progressVal = (int)value;
float percentage = ((float)progressVal / 100.0f); // Need to convert to float before division; otherwise C# returns int which is 0 for anything but 100%.
Brush backColorBrush = new SolidBrush(cellStyle.BackColor);
Brush foreColorBrush = new SolidBrush(cellStyle.ForeColor);
// Draws the cell grid
base.Paint(g, clipBounds, cellBounds,
rowIndex, cellState, value, formattedValue, errorText,
cellStyle, advancedBorderStyle, (paintParts & ~DataGridViewPaintParts.ContentForeground));
if (percentage > 0.0)
{
// Draw the progress bar and the text
g.FillRectangle(new SolidBrush(Color.FromArgb(203, 235, 108)), cellBounds.X + 2, cellBounds.Y + 2, Convert.ToInt32((percentage * cellBounds.Width - 4)), cellBounds.Height - 4);
g.DrawString(progressVal.ToString() + "%", cellStyle.Font, foreColorBrush, cellBounds.X+(cellBounds.Width/2)-5, cellBounds.Y + 2);
}
else
{
// draw the text
if (this.DataGridView.CurrentRow.Index == rowIndex)
g.DrawString(progressVal.ToString() + "%", cellStyle.Font, new SolidBrush(cellStyle.SelectionForeColor), cellBounds.X + 6, cellBounds.Y + 2);
else
g.DrawString(progressVal.ToString() + "%", cellStyle.Font, foreColorBrush, cellBounds.X + 6, cellBounds.Y + 2);
}
}
catch (Exception e) { }
}
}
}
Then I used that code to populate the GridView
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);
}
And here is the result
<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>
