DAtAgriDviEw添加行号

获取datagridview行号和列号,参考实例和注解如下: private void dataGridView1_CellEnter(object sender, DataGridViewCellEventArgs e) { iTag = (int)this.Tag; //if (iTag == 4) //{ // if (e.ColumnIndex ==3) // MessageBox.Show("该列为...

public Form1(){ InitializeComponent(); this.dataGridView1 .RowsAdded+=new DataGridViewRowsAddedEventHandler(dataGridView1_RowsAdded);}private void dataGridView1_RowsAdded(object sender, DataGridViewRowsAddedEventArgs e){ for (i...

控件添加如下事件即可在*号那个位置显示序号: //datagridview添加行号 private void dataGridView1_RowStateChanged(object sender, DataGridViewRowStateChangedEventArgs e) { e.Row.HeaderCell.Value = (e.Row.Index + 1).ToString(); }至于...

string newValue="test"; dataGridView2.Rows[i].Cells[0].Value=newValue;

可能有3种情况1.不是自动生成列的情况 :this.dataGridView1.AutoGenerateColumns = false;需要自己写代码设定 属性窗口中没有 可以写在Form_Load里没有给DataColumn设定DataPropertyName2.自动生成列的情况:应该设定成 this.dataGridView1.Aut...

//using System.Linq; private void button2_Click(object sender, EventArgs e) { int[] selIndexes = this.dataGridView1.SelectedRows .OfType() .Select(x => x.Index) .OrderBy(x => x) .ToArray(); foreach (int n in selIndexes) Messag...
