I need to display a popup dialog box when an Aspx page first loads. I do this inside of the page load method
with PageIsPostBack.
How can I prevent the popup from being displayed though when the user hits the refresh button or F5 button.
Or the back button?
if(!Page.IsPostBack)
{
// Dispaly popup here
}
After postback if user presses F5 or refresh duplicate values are inserted.
View 1 RepliesDo Not refresh the page if i press the f5 button in asp.net.
View 1 RepliesSome say it is not a bug it is default in asp.net. but for me it is a bug in logic. When you say refresh it should be reload the component that you are refreshing. But in asp.net i notice that they recalling all activity and viewstate like event and data that are triggered in the previous postback. My opinion it is a redo not refresh. this is only my observation on the issue dont hate me on this microsoft fan.
on aspx page:
private
static string __VIEWSTATE_FETCH;
protected void Page_Load(object sender,
EventArgs e){

after that i am going to some other page ,after going other page when i click on back button in browser it is coming in the previous page but the message which poped up before again getting popup.

View 1 RepliesI'm reading an invoice dataset and building a html table with checkboxes and textboxes in it, and I put that code in a postback = false block, then i got a button and a literal. The button click will loop through the html table checkboxes to calculate a total and assign it to the literal and display it. I got everything working except one thing, every time i click the button, the html table refreshes and lost all the value in textboxes....even though I put the html building block in the postback = false block,it seems like it still won't preserve the values in the textboxes once there's a button click...Anybody knows a solution to that? I want the textboxes keep what values are there.
Here is the code part:

I am a problem with Postback event.
I have a web page (aspx) which takes longer time to load the page. If this page is loading and if user requests same page by clicking menu link again, it is considered as not postback and page starts loading again (as soon as it finished first page load).
I want to prevent this from happening. When page is loading and user requests same page again, it should not process those requests and should be neglected.
This aspx page is requested from menu (which is designed on seperate master page).
I have 2 checkboxes (yes/no) that when selected cause the entire page to refresh during postback mode. How can I elimiate this?

How to prevent the content of the UpdatePanel from the PostBack which is occurred in the whole page ?
I have the following code:
<head runat="server">
<title></title>
<script type="text/C#" runat="server">
// I don't want it to call this event handler
[Code]....
The previous code will write in the TextBox2 in spite of it exists inside an UpdatePanel with Conditional for UpdateMode.
I want it to update only when I call UpdatePanel1.Update();
I have next situation:
1) Polls EF model (Poll (ID,Text),PollQuestions(ID, PollID, Answer),PollStatistics (ID,VotesCount))
2) Action in Home Controller named Poll which returns Poll model
3) Action in Home Controller names PollResult which returns PollStatistics model
4) On Partial View Poll (radiobuttons using PollQuestions list), ActionLink to post pack
5) On Partial View PollStatistics results information
6) In Home View <div id="Poll">{Here is shown Poll PartialView}</div>
I'm quite new to MVC tech. so the question would be how can I manage Ajax postback when ActionLink is pressed and show up polls result using PollStatistics? (How does result view is passed?) If it's possible - just simple example :)
I have a textbox added in an item template so I can enter data. But when I press enter in a textbox it caused the page to postback and I lose the data entered. I can tab through fine but why does Enter cause a postback? Can I disable this?

I have created a page with a gridview in asp.net that displays the records of a database table and allows users to delete checked records by clicking on a delete button. After I delete a record and I try to refresh the page from the browser (I am using mozilla)I get the follow message:
"To display this page, Firefox must send information that will repeat any action (such as a search or order confirmation) that was performed earlier."
and if I click resend another record is deleted automatically. Even though I am reloading the gridview after the deletion the application executes again the onclick event of the delete button is executed and the gridview things that there is a checkedbox selected so the code executes my delete function again.
Is there any way to get rid of these behavior. I have been trying quit a few things but nothing works for me.
I have a treeview loaded with nodes. When I click on a node that is set to .Selected, I want a frame to load with that node's objects. Instead, it appears that the TreeView is posting back and causing the node that was clicked to be lost. For example,setting the below function to OnSelectedNodeChanged causes a NullReferenceException.
Protected Function LoadObject(ByVal sender As Object, ByVal e As EventArgs)
Dim node As TreeNode = tv1.SelectedNode
Response.Write(node.Text.ToString())
I am checking to see on the form if they answer No to question one then go to comments. On the client side I added autopostback="true". So when the page reloads the random number in the label is updating to a new number. How can I avoid the random number not to be updated when the page post pack to itself?
Protected Sub form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles form1.Load
Dtetxt.Text = Date.Now
F()
End Sub
Private Sub F()
Dim _r As New Random()
Dim n As Integer = _r.[Next](5)
' Can return 0, 1, 2, 3, or 4
Label2.Text = n.ToString
End Sub
