当按下按钮时，它应该遍历所有选中复选框的项目.不确定是否是您的要求.

 受保护的 无效 Button1_Click(对象发​​件人，EventArgs e)
{
 // 遍历GridView中的所有行
  foreach (GridViewRow di  in  GridView1.Rows中)
 {
   CheckBox chkBx =(CheckBox)di.FindControl(" );
   如果(chkBx！= 空&& chkBx.已检查)
   {
      /// 将您的代码放在此处
}
 }
} 

Dim myCommand As New SqlCommand(sqlselect, myConnection)
Dim myReader As SqlDataReader
myConnection.Open()
myReader = myCommand.ExecuteReader()
If myReader.HasRows Then
While myReader.Read()
Dim isChecked As Boolean = DirectCast(FindControl("chkSelect"), CheckBox).Checked

If isChecked Then
empmail = myReader(column)
fn_AttachGrid(empmail)
Else
End If
End While
myReader.Close()
myConnection.Close()
Else
End If


i have a gridview and a checkbox item in gridview
when button is pressed it should iterate through all the items where check box is checked

解决方案

Please go through below code, see if it helps. Not sure though if it is your requirement.

protected void Button1_Click(object sender, EventArgs e)     
{
 // Looping through all the rows in the GridView          
 foreach (GridViewRow di in GridView1.Rows)         
 {          
   CheckBox chkBx = (CheckBox)di.FindControl("chkSelect");              
   if (chkBx != null && chkBx.Checked)            
   {
      /// put your code here             
   }         
 } 
}
