91 单元格中触发的事件，并且两个窗体之间的传值
92 private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
93 {
94 string name=dataGridView1[1, dataGridView1.CurrentCell.RowIndex].Value.ToString();
95 string psw=dataGridView1[2, dataGridView1.CurrentCell.RowIndex].Value.ToString();
96 Form1 form1 = new Form1();//这里是两个窗体之间传递值，需要设置两个字段
97 form1.name = name;
98 form1.psw = psw;
99 form1.Show();
100 }
101 获得当前单元格的内容也就是当前行第一列的值
102 Console.WriteLine(DataGridView1.CurrentCell.Value);
103 // 取得当前单元格的列 Index
104 Console.WriteLine(DataGridView1.CurrentCell.ColumnIndex);
105 // 取得当前单元格的行 Index
106 Console.WriteLine(DataGridView1.CurrentCell.RowIndex);
107 ' 删除名为"Column1"的列
108 DataGridView1.Columns.Remove("Column1");
109 ' 删除第一列
110 DataGridView1.Columns.RemoveAt(0);
111 移除当前行
112 this.dataGridView1.Rows.Remove(this.dataGridView1.CurrentRow);
113 ' 删除第一行
114 DataGridView1.Rows.RemoveAt(0);
115 获得此格的内容
116 DataGridView1【0，0】;
117 dataGridView1.AlternatingRowsDefaultCellStyle.BackColor = Color.MistyRose;//偶数行显示
118 dataGridView1.RowsDefaultCellStyle.BackColor = Color.MistyRose;//奇数行显示
119 显示选择的行
120
128 DataGridView的异常处理
129 1、 CellFormatting事件，每绘制一个单元格系统自动触发此事件
130 private void buttonCellValidating_Click(object sender, EventArgs e)
131 {
132 dataGridView1.CellValidating +=
133 new DataGridViewCellValidatingEventHandler(CellValidating);
134 MessageBox.Show("");
135
136 }
137 private void CellValidating(object sender, DataGridViewCellValidatingEventArgs e)
138 {
139 string errorMessage = "";
140 if (dataGridView1.Columns[e.ColumnIndex].Name == "学号")
141 {
142 if (e.FormattedValue == null)
143 {
144 errorMessage = "不允许空值";
145 }
146 else
147 {
148 string xuehao = e.FormattedValue.ToString();
149 if (xuehao.Length != 8)
150 {
151 errorMessage = "学号必须为8位数字";
152 }
153 else
154 {
155 for (int i = 0; i < xuehao.Length; i++)
156 {
157 if (char.IsDigit(xuehao[i]) == false)
158 {
159 errorMessage = "学号必须为8位数字";
160 break;
161 }
162 }
163 }
164 }
165 }
166 2、DataError事件，如果用户输入了不符合数据源规定的内容，系统在验证数据时就会产生异常
167 3、CellVaildating事件，当用户提交数据时响应这些事件
168
169
170
171
172 if (errorMessage.Length > 0)
173 {
174 MessageBox.Show(errorMessage, string.Format("第{0}行第{1}列有错",
175 e.RowIndex, e.ColumnIndex));
176 dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].ErrorText = errorMessage;//如果用户输入的值无效就可以触发这些事件
177 }
178 else
179 {
180 dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].ErrorText = null;
181 }
private void dataGridView1_MouseClick(object sender, MouseEventArgs e)
{
DataGridView.HitTestInfo h = dataGridView1.HitTest(e.X, e.Y);
if (h.Type== DataGridViewHitTestType.Cell || h.Type == DataGridViewHitTestType.RowHeader)
{
dataGridView1.Rows[h.RowIndex].Selected = true;
//鼠标点时可以获得一行数据，不管点任何一行都是一行数据
int processeId = (int)dataGridView1.CurrentRow.Cells[0].Value;
ShowProcessInfo(Process.GetProcessById(processeId));
}
}
