  how to disable a linkbutton to prevent submit several times

  Apr 06, 2012 07:48 AM|LINK

  I have HTML code like this

  <asp:LinkButton ID="AddButton" runat="server" OnClick="AddPatientBtn_Click">
  <span class="Normal">Add</span>
  </asp:LinkButton>

  I find if we click 'Add' several time, and it will add several patient records. I change the code like this

  i use js like:

  button.disabled = true or button.disabled = 'disabled'

  but it still can add several patient records

  what should i do ?

  in linkbutton click event, make it visible false

  protected void AddButton_Click(object sender, EventArgs e)
  {
  
          AddButton.Visible = false;
  
  }

  Hi,

  Check out following links:

  http://stackoverflow.com/questions/6284861/asp-net-prevent-double-clicking

  http://www.codeproject.com/Questions/114164/Prevent-user-from-clicking-submit-multiple-times

  http://stackoverflow.com/questions/926816/how-to-prevent-multiple-form-submit-from-client-side

  http://forums.codeguru.com/showthread.php?t=480279

  Though, the problem of duplicate entry in the database can be handled by enforcing some unique key in the table.

   

  Thank you

  Hope it'll help you..

  when i click add button, it still there.

  i think when the page is send to server ,it will display the 'Add' link

  because the new page has not be send back from server where AddButton.Visible is false.

  button.disabled = true or button.disabled = 'disabled'

  Hello,

  I don't think you can do like this. Use below syntax

  document.getElementById('<%=AddButton.ClientID%>').disabled = true;

  Thanks for all of you!

  I find that LinkButton may not have the disable attribute, it is a <a> in html page.

  so I use another solution

  <asp:LinkButton ID="AddButton" runat="server" OnClick="AddPatientBtn_Click" OnClientClick="return DisableButton()">
  <span class="Normal">Add</span>
  </asp:LinkButton>

  js:

  var pending = false;
  function DisableButton() {
  if (pending) {
      alert("The new patient is being created. Please wait...");
      return false;
      }
      else {
           if (Page_ClientValidate(""))
           pending = true;
           return true;
       } 
  }
