Hi guys, I want Ascii value for Refresh button. I think Refresh button and F5 function are same . But problem here is , one Linkbutton in my page , when click on the Linkbutton open the new window. Here is when click on the refresh button or F5 , it will open the same window again.

I wrote the code for stoping F5 :

C#

document.attachEvent("onkeydown", my_onkeydown_handler);
window.history.forward(1);
document.attachEvent("onkeydown", my_onkeydown_handler);


function my_onkeydown_handler() {
 switch (event.keyCode) {

      case 116: // 'F5'
          event.returnValue = false;
          event.keyCode = 0;
         // window.status = "We have disabled F5";
          window.event.cancelBubble = true;
          break;
      }
  }

F5 ascii is 116,
is there solution for stoping refresh button of browser .

Who told you there should be such weird thing as the ASCII value? Besides, each browser could do it its own way...

"F5 ascii is 116". To start with, please try not to lie.

Key code has nothing to do with ASCII. I told you that you should not lie, but instead you lie again.

Solution 2

No for that you have to open pop-up window using window.open() function...In this function you can specify many option so not display toolbar of browser so its solve your problem..& disabled F5 key using your javascript code...So by both these way you restrict end user to refresh your page...For more information of windwo.open() check given link

hi,I was mentioned in the below code . But it does not working.

Protected Sub lbnDetails_Click(ByVal sender As Object, ByVal e As System.EventArgs)

Try lblRecordsperPage.Visible = True

ddlRecordsperPage.Visible = True

'When Clicking on the View LinkButton. It will Redirect to the Lease Details Page.

Dim lbnDetails As LinkButton = CType(sender, LinkButton)

'*** Creating Object for GridViewRow

Dim gvRow As GridViewRow = CType(lbnDetails.NamingContainer, GridViewRow)

'*** Getting Values of Fields Using DataKeyNames

objLeaseSearch.LeaseID = gvwLeaseReviewSummary.DataKeys(gvRow.RowIndex).Values(0)

objLeaseSearch.LeaseVersionNumber = gvwLeaseReviewSummary.DataKeys(gvRow.RowIndex).Values(1)

ScriptManager.RegisterStartupScript(Me.Page, Me.GetType(), "Window", "ViewInternalID();", True)

Catch ex As Exception

SetUserMessage(ex.Message, MessageType.ErrorMessage)

ErrorSignal.FromCurrentContext.Raise(ex) End Try End Sub

function ViewInternalID() {

window.open("LeaseDetail.aspx",'_blank','width=800px,height=500px,scrollbars=yes, status=no, resizable=yes,titlebar=yes,menubar=yes');

}

The "refresh button" does not have an ASCII value, or a keycode - it is not activated by the keyboard, it is a mouse click.

You cannot disable F5 reliably in all browsers, and AFAIK it can't even be disabled reliably in any browser! The refresh button you have no access to at all in all browsers.

how to resolve my problem. Is there any other solution.

Please, stop it. This is not your problem. You problem that you don't tell us your real goal, or worse, don't know it yourself (which is very likely). The whole idea is totally wrong. You can get any help only if you explain why are you trying to do such weird thing.

I would not pay much attention for this (correct) answer if not the OP's comment and someone's idiotic vote of 3. I voted 5 (not to compensate, but because this is a correct answer).

HI, I don't know more knowledge of the .net. But i would like to interest on the .net. Could you help me.

:laugh:
Not really - it is absolutely enormous! There are over 40,000 types in .NET 4.0, so it's not a job anyone can do in a text box. :)
What I would suggest is get a book - anything that doesn't have multiple exclamation marks or the works "in xx Days" in the title should be a good start - and work your way through it. That way, you get things explained in a sensible order, with discussions on why to do things, as well as what to do.
