Question

I have designed a gridview with a radio button inside the itemtemplet. I also have a confirm button. A user is allowed to check several radio button and when a confirm button is pressed then database is updated with the value of radio button.

But when i check the button it is shown as checked in UI but when I check through code behind, it shows checked property of radio button as false.

  for (int i = 0; i < gvTransaction.Rows.Count; i++)
  {
      if (!((String.IsNullOrEmpty(gvTransaction.Rows[i].Cells[0].Text)) || (gvTransaction.Rows[i].Cells[0].Text == "&nbsp;")))
      {
          string transactionID = gvTransaction.Rows[i].Cells[0].Text;
          RadioButton btn = (RadioButton)gvTransaction.Rows[i].FindControl("rbtSelect"); 
          if (btn.Checked)
          {
              // Although the radiobutton is checked code never reach here. 
          }
      }
  }

How are you binding the GridView? If you are doing it in Page Load, make sure that you are not reloading the gridView on page PostBacks

protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { //Bind GridView here } 

do let us know if this help
