  how to find a checkbox control in repeater? my code is not working..

  protected void Button1_Click(object sender, EventArgs e)
      {
          foreach (RepeaterItem i in Repeater1.Items)
          {
              CheckBox chb = (CheckBox)i.FindControl("CheckBox1");
            
              if (chb.Checked)
              {
  
                  
                  dcdc.modify_request(true);  // procedure called;
  
  
              }
             else { Response.Write("not found in "+i+itration); }
  
          }

  Hi,

  protected void Button1_Click(object sender, EventArgs e)
      {

  		
  		for (int itemCount = 0; itemCount < rptrSubjects.Items.Count; itemCount++)
  		{
  			CheckBox chkBox = ((CheckBox)rptrSubjects.Items[itemCount].FindControl("chkSubjects"));
  			if (chkBox != null && chkBox.Checked == true)
  			{
  				lblStatus.Text = lblStatus.Text + ""+ chkBox.Text;
  				lblStatus.Text = lblStatus.Text + "</br>";
  			}
  		}
  
  		
  
  	}

  Hi, there is no error in your above codes. Please check your markup to make sure “CheckBox1” exists in your repeater. You can also paste your markup here, we will help to check them.

  my code is correct then their is problem with the procedure called in the code.

  the procedure is not able to modify each row of the repeater.

  public DataClassesDataContext dcdc = new DataClassesDataContext();
  
  
  
  for (int count = 0; count < Repeater1.Items.Count; count++)
              {
                  CheckBox chb = ((CheckBox)Repeater1.Items[count].FindControl("CheckBox1"));
  
  
                  //CheckBox chb = (CheckBox)i.FindControl("CheckBox1");
                  // Label lab=(Label)i.FindControl("Label1");
                  if (chb != null && chb.Checked == true)
                  {
                      
  
                      dcdc.modify_request(true);
  
  
                  }
                  
              }
          
  
  
  //repeater1 binded again.

  
  the procedured

  dcdc.modify_request(true);

   is not modifying the values in each row. // the procedure is called to modify the checked users verifcation_id to true when button is clicked. how i called the procedure.???

  Hi, please set breakpoints to:

  exbond

  dcdc.modify_request(true);

  and debug the codes to check where the issue occurs. Additionally, please paste your codes (dcdc.modify_request();)here for analysis.
