在WinForm中,双击DataGridView列头设置当前列的显示为指定的图片
在WinForm中,双击DataGridView列头设置当前列的显示为指定的图片,
再双击时列头显示回之前的文字 --------------------编程问答--------------------
public partial class Form1 : Form
{
bool flag = true;
bool show = true;
int index = 0;
public Form1()
{
InitializeComponent();
this.dataGridView1.Rows.Add("1", "1", "1", "1");
this.dataGridView1.Rows.Add("1", "1", "1", "1");
this.dataGridView1.Rows.Add("1", "1", "1", "1");
this.dataGridView1.Rows.Add("1", "1", "1", "1");
this.dataGridView1.Rows.Add("1", "1", "1", "1");
}
private void dataGridView1_ColumnHeaderMouseDoubleClick(object sender, DataGridViewCellMouseEventArgs e)
{
if (flag)
{
this.dataGridView1.Columns[e.ColumnIndex].Visible = false;
DataGridViewImageColumn iconColumn = new DataGridViewImageColumn();
iconColumn.Image = GetImage(Application.StartupPath + @"\g.png");
iconColumn.Name = "new";
iconColumn.HeaderText = "new";
dataGridView1.Columns.Insert(e.ColumnIndex, iconColumn);
index = e.ColumnIndex;
flag = false;
}
else
{
this.dataGridView1.Columns[index].Visible = !show;
this.dataGridView1.Columns[index + 1].Visible = show;
show = !show;
}
}
private Image GetImage(string path)
{
FileStream fs = new FileStream(path, System.IO.FileMode.Open);
Image result = Image.FromStream(fs);
fs.Close();
return result;
}
}
好久木有写过代码了啊，将就将就看吧…… --------------------编程问答-------------------- 呃，上面没有考虑当前列问题，不过那应该不是什么大问题 --------------------编程问答-------------------- 不是整列显示指定图片,而是列标头显示就可以了.
比如是DataGridVeiwTextBoxColumn.双击它的列标头可以在列标头上显示指定的图片,再双击那图片去可以去掉
补充：.NET技术 , C#
