为什么我根据ID号来删除,怎么一删就删两个的了
public void Delete_Click(object sender, System.EventArgs e)
{
foreach(DataGridItem Item in JDataGrid.Items)
{
if(((CheckBox)Item.FindControl("chkDel")).Checked)
{
DeleteRow(this.JDataGrid.DataKeys[(int)Item.ItemIndex-1].ToString());
}
}
Operater operater=new Operater();
DataSet ds=operater.executeDataSet(sql);
this.JDataGrid.DataSource=ds;
this.JDataGrid.DataBind();
operater.Close();
}
//实现删除
private void DeleteRow(string t)
{
string strCon = "server=.;database=ipsoon;uid=sa;password=";
SqlConnection conn = new SqlConnection(strCon);
SqlCommand Cmd = new SqlCommand("delete from PE_Article where ArticleID='"+t+"'",conn);
conn.Open();
Cmd.ExecuteNonQuery();
conn.Close();
}
public void Delete_Click(object sender, System.EventArgs e)
{
foreach(DataGridItem Item in JDataGrid.Items)
{
if(((CheckBox)Item.FindControl("chkDel")).Checked)

conn.Close();
