Solution 1

1. Loop through all the datalist items.
2. Use FindControl method on datalist item to get the checkbox in discussion
3. Check if it is checked or not. In case it is, then use FindControl again to get the hidden label value.

Try!

UPDATE:
Try something like...

C#

int count = dl.Items.Count; 
for (int i = 0; i < count; i++) 
{
  Checkbox chk = dl.Items[i].FindControl("chkID") as Checkbox;
  if(chk.Checked)
  { 
    Label ID = dl.Items[i].FindControl("lblID") as Label; 
    string item = ID.Text; 
    // if more than one is checked, continue the loop and track all the texts. 
    // Like: string selectedItemTexts += ID.Text + ",";
  }
}

hi i need to get the only the checked event column value
int count = dl.Items.Count;
for (int i = 0; i < count; i++) {
Label ID = dl.Items[i].FindControl("lblID") as Label;
string item = ID.Text;
}

Here as per ur advice we can use condition to get the checked value, but i need only the row by which the checked event happen?

Its good to see,I need to get only the row value at where the checkbox checked event is happen that is: after loading the datalist, if i click any one checkbox from the list, i need to get that row value and do some calculation and then again bind the datalist,
