我有一个WinForm应用程序,在此表单上我有以下控件。
1-Grid view
2-Copy button
- 如何在网格视图的第一行旁边只放置一个按钮(复制按钮)? - 单击复制按钮后,如何填充第一行并使其他16行与我的第1行相同?但只有不同的ID才能获得递增的值。
示例:
ID Explanation Teacher_ID
--- ----------- ----------
0 hello 45 CopyButton
1 hello 45
2 hello 45
3 hello 45
. . .

. . .
16 hello 45
答案 0 :(得分:0)
创建一个查找类
public class LookUp
{
public long Id { get; set; }
public string Explanation { get; set; }
public long TeacherId { get; set; }
}
点击按钮
private void ClickEvent()
{
//Use correct columnId or name here
var name = dataGridView1.Rows[1].Cells[2] != null ? dataGridView1.Rows[1].Cells[2].ToString() : "";
var id = dataGridView1.Rows[1].Cells[3] != null ? long.Parse(dataGridView1.Rows[1].Cells[3].ToString()) : 0;
var datalist = GetList(name, id, 16); //you have a copy of values with diffrent ids -- rest is for you
}
//create a method which return copy of values but with different id
private IEnumerable<LookUp> GetList(string name, long id,int till)
{
for (var i = 1; i <= till; i++)
{
yield return new LookUp() { Id = i, Explanation = name,TeacherId = id};
}
}
