Question

如何在DataGridView的cell中添加UserControls

Answer 1

这个我刚好会,以前看了别人的博客学会的

先从工具箱拖一个textbox到窗体form1中.然后设置其为visible属性为false

在窗体加载中写
private void Form1_Load(object sender, EventArgs e)
{

textBox1.Visible = false;
textBox1.Width = 0;
dataGridView1.Controls.Add(textBox1); //这句很重要的
}

datagridview1的CurrentCellChanged的事件中写
private void dataGridView1_CurrentCellChanged(object sender, EventArgs e)
{
this.textBox1.Visible = false;
this.textBox1.Width = 0;
try
{
//前提是你的datagridview1一定要有数据呀
if (dataGridView1.Columns[dataGridView1.CurrentCell.ColumnIndex].HeaderText == "你选中的单元格所在的列名")
{
//以下是把把textbox1的位置与datagridview1的单元格的位置一样,不过长宽均比单元格的短2
this.textBox1.Left = dataGridView1.GetCellDisplayRectangle(dataGridView1.CurrentCell.ColumnIndex, dataGridView1.CurrentCell.RowIndex, true).Left;
this.textBox1.Top = dataGridView1.GetCellDisplayRectangle(dataGridView1.CurrentCell.ColumnIndex, dataGridView1.CurrentCell.RowIndex, true).Top;
this.textBox1.Width = dataGridView1.GetCellDisplayRectangle(dataGridView1.CurrentCell.ColumnIndex, dataGridView1.CurrentCell.RowIndex, true).Width-2;
this.textBox1.Height = dataGridView1.GetCellDisplayRectangle(dataGridView1.CurrentCell.ColumnIndex, dataGridView1.CurrentCell.RowIndex, true).Height - 2;

string str = Convert.ToString(this.dataGridView1.CurrentCell.Value); this.textBox1.Text = str;//将单元格的值赋给文本框
this.textBox1.Visible = true;
}
}
catch
{
}
}
在文本框的Validating事件中
private void textBox1_Validating(object sender, CancelEventArgs e)
{
this.dataGridView1.CurrentCell.Value = this.textBox1.Text;//如果文本框输入内容后,把其值赋给其对应的单元格
}
