Today, at the time of online shopping, I saw a child boots mention of this issue, read the post and found the landlord finally gives his own solution, I feel pretty good, so the content of the post of finishing the next, turn out
Thinking solution is this: create three new button template columns, delete the first picture, a second display to edit images, add a third display picture to see the code.
Code first button template column:
a using the System;
the using the System.Windows.Forms;
namespace two combined heads column headings redraw
{
public class DataGridViewButtonColumnDel: the DataGridViewColumn
{
public DataGridViewButtonColumnDel ()
{
this.CellTemplate new new DataGridViewButtonCellDel = ();
this.HeaderText = "Button";
}
}
}
the System the using;
the using the System.Windows.Forms;
the using the System.Drawing;
namespace two combined heads column headings redraw
{
public class DataGridViewButtonCellDel: DataGridViewButtonCell
{
protected void the override the Paint (
Graphics graphics,
Rectangle clipBounds,
Rectangle cellBounds,
int rowIndex,
DataGridViewElementStates cellState,
object value,
object formattedValue,
string errorText,
DataGridViewCellStyle cellStyle,
DataGridViewAdvancedBorderStyle advancedBorderStyle,
DataGridViewPaintParts paintParts)
{
base.Paint(graphics, clipBounds, cellBounds, rowIndex, cellState, value, formattedValue, errorText, cellStyle, advancedBorderStyle, paintParts);
Image _img = Properties.Resources.imgDelete_x16;
graphics.DrawImage(_img, cellBounds.Location.X + 5, cellBounds.Location.Y+3, _img.Width, _img.Height);
}
}
}
Second button code template columns:
the using the System;
the using the System.Windows.Forms;
namespace two combined heads column headings redraw
{
public class DataGridViewButtonColumnEdi: the DataGridViewColumn
{
public DataGridViewButtonColumnEdi ()
{
this.CellTemplate new new DataGridViewButtonCellEdi = ();
the this = .HeaderText "Button";
}
}
}
the using the System;
the using the System.Windows.Forms;
the using the System.Drawing;
namespace two combined heads column headings redraw
{
public class DataGridViewButtonCellEdi: DataGridViewButtonCell
{
protected void the override the Paint (
Graphics Graphics,
the Rectangle clipBounds,
Rectangle cellBounds,
int rowIndex,
DataGridViewElementStates cellState,
object value,
object formattedValue,
string errorText,
DataGridViewCellStyle cellStyle,
DataGridViewAdvancedBorderStyle advancedBorderStyle,
DataGridViewPaintParts paintParts)
{
base.Paint(graphics, clipBounds, cellBounds, rowIndex, cellState, value, formattedValue, errorText, cellStyle, advancedBorderStyle, paintParts);
Image _img = Properties.Resources.imgEdit_x16;
graphics.DrawImage(_img, cellBounds.Location.X + 5, cellBounds.Location.Y + 3, _img.Width, _img.Height);
}
}
}
第三个按钮模板列的代码：
using System;
the System.Windows.Forms the using;
namespace two combined heads column headings redraw
{
public class DataGridViewButtonColumnAdd: the DataGridViewColumn
{
public DataGridViewButtonColumnAdd ()
{
this.CellTemplate new new DataGridViewButtonCellAdd = ();
this.HeaderText = "Button";
}
}
}
the using the System ;
the using the System.Windows.Forms;
the using the System.Drawing;
namespace two combined heads column headings redraw
{
public class DataGridViewButtonCellAdd: DataGridViewButtonCell
{
protected void the override the Paint (
Graphics Graphics,
the Rectangle clipBounds,
the Rectangle cellBounds,
int rowIndex,
CellState DataGridViewElementStates,
Object value,
Object formattedValue,
String the errorText,
the DataGridViewCellStyle CellStyle,
DataGridViewAdvancedBorderStyle advancedBorderStyle,
DataGridViewPaintParts paintParts)
{
base.Paint (Graphics, clipBounds, cellBounds, rowIndex, cellState, value, formattedValue, the errorText, CellStyle, advancedBorderStyle, paintParts);
Image = Properties.Resources.imgAdd_x16 _img;
Graphics.DrawImage (_img, cellBounds.Location.X. 5 +, + cellBounds.Location.Y. 3, _img.Width, _img.Height);
}
}
}
the above code is almost the same, red is loaded with a different part of the picture.
The picture is introduced through the project resource file. Method is: Open Windows Explorer, expand the "Properties" node (this node is hidden by default). Double-click Resources.resx, click "Add Resources", select "Add existing resources"; add three pictures: imgDelete_x16.png, imgEdit_x16, imgAdd_x16.png,
After dragging on form1 a DataGridView1, to DataGridView1 manually add two, respectively DataGridViewButtonColumnDel created above, DataGridViewButtonCellEdi two buttons template columns, ID, respectively Column1, Column2;
form1 background code is as follows:
a using System;
a using the System.Collections .Generic;
the using the System.ComponentModel;
the using the System.Data;
the using the System.Drawing;
the using the System.Text;
the using the System.Windows.Forms;
