Example of foreach traversal usage of GridView DataList and DataGrid data controls in ASP. NET

This paper describes the traversal usage of foreach in ASP. NET, GridView, DataList and DataGrid. Share it for your reference, as follows:

//gridview The traversal is as follows:  
foreach (GridViewRow row in GridView1.Rows)
{
  CheckBox cb = (CheckBox)row.FindControl("CheckBox2");
  if (cb.Checked == true)
  {
  }
}
//datagrid Traversal: 
foreach (DataGridItem oItem in ItemsGrid.Items)
{
  CheckBox ck1 = (CheckBox)oItem.FindControl("CheckBox");
  if (ck1.Checked == true)
  {
  }
}
//datalist Traversal 
foreach (DateListItem dl in DataList1.Items)
{
  CheckBox cb = (CheckBox)dl.FindControl("CheckBoxID ");
  if(cb.checked)
  ......
}

GridView:

for(int i=0; i <GridView.Rows.Count;i++)
{
   Label lbl = (Label)GridView.Rows[i].FindControl("Label9") ; 
}

Repeater:

for(int i=0; i < Repeater.Items.Count;i++)
{
  Label lbl = (Label) Repeater.Items[i].FindControl("Label9") ; 
}

DataList:

for(int i=0; i < DataList.Items.Count;i++)
{
  Label lbl = (Label) DataList.Items[i].FindControl("Label9") ; 
}
