在dataGridView的单元格中托管Button控件

一、在dataGridView的cell单击事件中构造含Button控件的文本框无法显示在dataGridView中的单元格中

   private void dgvAccountContrast_CellClick(object sender, DataGridViewCellEventArgs e)
        {
            if (e.ColumnIndex == accountCode.Index)
            {
                try
                {
                    Rectangle rect = this.dgv_accountCodeContrast.GetCellDisplayRectangle(e.ColumnIndex, e.RowIndex, true);

                    //adding textboxbutton control at code column
                    //在dataGridView的cell单击事件中构造含Button控件的文本框无法显示在
                    //dataGridView中的单元格中
                    this.textBoxWithButton = new TextBoxWithButton();

                    this.textBoxWithButton.btnCode.Click += new EventHandler(btnCode_Click);
                    this.textBoxWithButton.Leave += new EventHandler(txtbtnControl_Leave);
                    this.textBoxWithButton.txtCode.TextChanged += new EventHandler(txtCode_TextChanged);

                    this.textBoxWithButton.Visible = false;
                    this.dgv_accountCodeContrast.Controls.Add(this.textBoxWithButton);
                    this.textBoxWithButton.Location = rect.Location;
                    this.textBoxWithButton.Size = rect.Size;

                    this.textBoxWithButton.btnCode.Text = "...";
                    //textBoxWithButton.Refresh();
                    this.textBoxWithButton.Visible = true;
                    this.textBoxWithButton.Focus();
                    if (!string.IsNullOrEmpty(this.dgv_accountCodeContrast.CurrentRow.Cells[accountCode.Name].Value.ToString()))
                    {
                        this.textBoxWithButton.txtCode.Text = this.dgv_accountCodeContrast.CurrentRow.Cells[accountCode.Name].Value.ToString();
                    }
                    else
                    {
                        this.textBoxWithButton.txtCode.Text = "";
                    }
                }
                catch (Exception) { }
            }
        }

二、构造窗体时即构造含Button控件的文本框(自定义控件)，在dataGridView的Cell单击事件中仅设定含Button控件的文本框可见于事件中的单元格，

此时，可以显示在dataGridView中的单元格中,但是无法更改自定义控件的大小，即使编程中更改的自定义控件的大小

2.1 构造窗体时即构造含Button控件的文本框(自定义控件)代码：

 void InitializeControlsState()
        {
            //表头样式
            DataGridViewCellStyle style = new DataGridViewCellStyle();
            style.Alignment =
                DataGridViewContentAlignment.MiddleCenter;
            style.ForeColor = Color.IndianRed;
            style.BackColor = Color.Ivory;
            style.Font = new Font(dgv_accountCodeContrast.Font, FontStyle.Bold);

            dgv_accountCodeContrast.ColumnHeadersDefaultCellStyle = style;

            this.accountCode = new DataGridViewTextBoxColumn();
            this.accountCode.Name = "本地科目编码";
            //定义列的排列顺序
            accountCode.DisplayIndex = 0;
        
            this.accountCode.Width = 270;
            //this.accountCode.Resizable = DataGridViewTriState.False;
            this.dgv_accountCodeContrast.Columns.Add(accountCode);

            this.Description = new DataGridViewTextBoxColumn();
            this.Description.Name = "本地科目名称";
            Description.DisplayIndex = 1;
           
            this.Description.Width = 150;
            this.dgv_accountCodeContrast.Columns.Add(Description);

            //adding textboxbutton control at code column...
            this.textBoxWithButton = new TextBoxWithButton();
            this.textBoxWithButton.Visible = false;
            this.dgv_accountCodeContrast.Controls.Add(this.textBoxWithButton);
        }

2.2设定自定义控件的显示位置的代码：

   private void dgvAccountContrast_CellClick(object sender, DataGridViewCellEventArgs e)
        {
            if (e.ColumnIndex == accountCode.Index)
            {
                try
                {
                    Rectangle rect = this.dgv_accountCodeContrast.GetCellDisplayRectangle(e.ColumnIndex, e.RowIndex, true);

                    //adding textboxbutton control at code column
                    //在dataGridView的cell单击事件中构造含Button控件的文本框无法显示在
                    //dataGridView中的单元格中
                    //所以只在此处设定自定义控件的显示位置
                    
                    this.textBoxWithButton.Location = rect.Location;

                    //虽然更改了自定义件的大小，但不生效
                    this.textBoxWithButton.Size = rect.Size;

                    this.textBoxWithButton.btnCode.Text = "...";
                  
                    this.textBoxWithButton.Visible = true;
                    this.textBoxWithButton.Focus();
                    if (!string.IsNullOrEmpty(this.dgv_accountCodeContrast.CurrentRow.Cells[accountCode.Name].Value.ToString()))
                    {
                        this.textBoxWithButton.txtCode.Text = this.dgv_accountCodeContrast.CurrentRow.Cells[accountCode.Name].Value.ToString();
                    }
                    else
                    {
                        this.textBoxWithButton.txtCode.Text = "";
                    }
                }
                catch (Exception) { }
            }
        }
