C#關於DataGridView控件的使用總結

DataGridView常用方法：
dataGridView1.ReadOnly = true;//全部單元格隻讀 

	

dataGridView1.Columns[1].ReadOnly = true;///指定單元格設置隻讀（列）第一列 

dataGridView1.Rows[2].ReadOnly = true;///指定單元格設置隻讀 （行）第二行 

dataGridView1[1, 2].ReadOnly = true;///指定單元格設置隻讀 （第1行，第2列）利用坐標 

	

dataGridView1.AllowUserToAddRows = false;//禁止用戶追加行 

dataGridView1.AllowUserToDeleteRows = true;//允許用戶刪除行操作 

	

//提示是否刪除指定行數據 

private void dataGridView1_UserDeletingRow(object sender, DataGridViewRowCancelEventArgs e)
        {
   DialogResult diaR = MessageBox.Show("刪除該行嗎?", "確認", MessageBoxButtons.OKCancel, MessageBoxIcon.Question); if (diaR == DialogResult.OK)
            {
                e.Cancel = false;
            }
}

	

//提示刪除了哪一行數據
private void dataGridView1_UserDeletedRow(object sender, DataGridViewRowEventArgs e)
        {
            System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder(); 

messageBoxCS.AppendFormat("{0} = {1}", "行號為", e.Row); messageBoxCS.AppendLine(); 

DialogResult diaR = MessageBox.Show("刪除了" + messageBoxCS.ToString(), "確認"); }

	

//刪除選定的多行 foreach(  DataGridViewRow r in dataGridView1.SelectedRows)
 { if (r.IsNewRow == false)    {   ataGridView1.Rows.Remove(r);     }      
}

	

取得選定的行、列、單元格
//選定的單元格
            foreach (DataGridViewCell c in dataGridView1.SelectedCells)
            {
                string cr = string.Format("{0},{1}", c.ColumnIndex, c.RowIndex); listBox1.Items.Add("選定的單元格位置是：" + cr); }

	

//選定的行/列
            foreach (DataGridViewRow c in dataGridView1.SelectedRows)
            {
                listBox1.Items.Add("選定的行是：" + c.RowIndex); }
foreach (DataGridViewColumn c in dataGridView1.SelectedColumns)
            {
                listBox1.Items.Add("選定的列是：" + c.ColumnIndex); }

	

//指定選定單元格
         dataGridView1[0, 0].Selected = true; dataGridView1.Rows[0].Selected = true; 

dataGridView1.Columns[0].Selected = true; 

	

//設置行內容
            dataGridView1.Rows[0].HeaderCell.Value = "第1行"; 

	

//利用數組添加添加數據時，類型都是默認的字符串類型 

string name = "Jim"; 

string gender = "男"; 

string age = "18"; //將上麵三個變量合成一個數組 

string[] row = { name, gender, age }; //給dataGridView1控件添加數據 

dataGridView1.Rows.Add(row);//添加數據 

	

/

/左上角的文字
            dataGridView1.TopLeftHeaderCell.Value = "左上角"; 

	

//列中顯示選擇框CheckBox
            DataGridViewCheckBoxColumn column1= new DataGridViewCheckBoxColumn(); {
                column1.HeaderText = "選擇框"; column1.Name = "checkbox"; column1.AutoSizeMode =
                DataGridViewAutoSizeColumnMode.DisplayedCells; column1.FlatStyle = FlatStyle.Standard; //顯示選擇框的三種狀態
                 column1.ThreeState = true; }
            dataGridView1.Columns.Add(column1); 

	

//顯示按鈕控件 DataGridViewButtonColumn col=new DataGridViewButtonColumn();
            col.Name="Button";
            col.UseColumnTextForButtonValue=true;
            col.Text = "按鈕";
            dataGridView1.Columns.Add(col);
觸發的事件為： private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
        { if (dataGridView1.Columns[e.ColumnIndex].Name=="Button")
            {
                MessageBox.Show("觸發了按鈕");
            }
 }

	

單元格列顯示圖像的是：DataGridViewImageColumn

//顯示圖像
            DataGridViewImageColumn dgvI=new DataGridViewImageColumn(); 

dgvI.Name="Image";

 dgvI.ValuesAreIcons=false; 

dgvI.Image = new Bitmap("c://windows//Blue Lace 16.bmp"); 

dgvI.ImageLayout=DataGridViewImageCellLayout.Zoom;

 dgvI.Description="測試的圖片"; dataGridView1.Columns.Add(dgvI);

 dataGridView1["Image", 0].Value = new Bitmap("c://windows//Blue Lace 16.bmp"); 

	

//獲取總行數：
dataGridView1.Rows.Count; 

	

獲取當前選中行索引：
int i = this.dataGridView1.CurrentRow.Index; 獲取當前選中列索引：
int j = this.dataGridView1.CurrentCell.ColumnIndex;
