How to find child controls in asp.net dynamically

for (int row = 0; row < 10; row++) 

{

TableRow tr= new TableRow();

tr.ID = string.Format("tr_{0}", row);

for (int cell = 0; cell < 4; cell++) 

{

TableCell tc= new TableCell();

tc.ID = string.Format("tc_{0}{1}", row, cell); 

}

 

table.Rows.Add(tc);

 

 

 

  

} 

 

 

On the above highlighted I could just remove a hyperlink for row 0 and tablecell 3. I need to make dynamic, in that way it removes the hyperlink if I click row 5 or so on so forth.. Right now I hardcoded but hwo to make that tr_0 as tr_i or something for each row selected and tc_03 something dynamic?
