I am trying to get a functionality where on a click event a popup comes up. And on this pop up there are controls like a text box,a button and a grid which can speak back and forth with the server. Also I need to get values from the grid when the pop up is destroyed.

Got a pretty simple page where i want an update panel to become visible or hidden based on a button click. When i run this page in VS2010 in debug mode it works as i expected it to - page does not post back, the panel just appears or disappears on the page without the whole page refreshing.
I uploaded this to my server, and the page is posting back when you click the button.
Server is win2k8R2 x64 IIs7.5
Do i need to enable anything in the IIS configuration?
when any Button control is clicked generally it Postback the page to itself, and the same page is regenerated.This is the usual defination of postback in context of a Button Control. But my dear friends i am confused that what is the actual mechanism behind this.Okey say for definition the above statement is fine but believe me i not not getting the actual meaning.What is posting back the Page? What is Page in browser's context? There is only html markup, JavaScript and CSS codes in browser's page.These make up the html page. I think there is no any relation of this Browser's page with ASP.NET Page class. What does it mean that browser's content is posted back to the Page itself ?
View 1 RepliesI have a problem of posting back in my website in some browsers. The Problem is: When I am uploading a file using file upload and button or posting page back on some event click after button click I am using:
ClientScript.RegisterClientScriptBlock(Me.GetType, "AddData", "alert('" & f_u_devideo.FileName & " Uploaded Successfully');", True)
But after that the page not not load again and a blank page comes in some browsers
I used the following code for the form download

But form is not posting back on execution of the above statement. What should I do , so that form postback also occurs after this statement.
I have a button on my web form. When it is pressed, the event method for that button is called as it should be. However before the buttons method is called, the page load event is first called. Is there a way to prevent the page load event from being called when the button is pressed? I know about using !Page.IsPostback in the Page load method. However I wish to avoid posting back to the Page Load method altogether when this particular button is pressed.

I have a keyboard-controlled menu which I did with jquery (When I press down, it marks second option and so on...)
But after I select the option I need, I want to click enter to call the button's OnClick method as if the user really clicked it. Which means I have to do a postback.
how do I do that?
i have the below page and i am racking my brain as to why when i have two update panels do they both get post backs. i can tell cause i have two user controls- one in each panel and they both fire page load events when only the left panel should be posing back and updating itself... or else whats the point of update panels if in reality the entire page is posting back!

I have a repeater that has a LinkButton in the Item Template. The LinkButton displays a UserControl that consists of a FormView. The UserControl has an HTML Element that when clicked hides the UserControl by simply change the display of the control from 'block' to 'none'. If the 'Close' span is clicked, the UserControl is successfully hidden, but afterward, the 'Edit' linkbuttons no longer postback.
View 1 RepliesI found alot of thread about how to postback after close the modal popup.
But for me, the system has already did it for me.
How to prevent page from posting back?
here's my code
[Code]....
I have a control which inherits from LinkButton and I'm trying to make sure that the user cannot cause mayhem by performing multiple postbacks. That seemed an easy enough challenge, so I have this code [snippet] on the client:
[Code]....
The alert is of course only there for debugging. If the DisableOnClick value is false, then I see the "Posting Back" alert and, when I click ok, the postback occurs - all good.
If the DisableOnClick value is true, then the "button" gets disabled and the cursor turns into an hourglass - again good. But the postback doesn't happen - not good. I assume that the ASP client code is trying to preventing the postback when it sees that the link is disabled.
So, how can I either:
Persuade the LinkButton to postback even though it has just been disabled; or[probably better] Get my client code to execute immediately after the postback code rather than before.
I'm using ASP.NET MVC to try to postback after confirmation using javascript, this is the button:
<input type="submit" id ="RemoveStatus" value="Remove Status" name="button" onclick="return CheckRemove();"/>
This is my javascript in my CheckRemove() js function:
var button1 = document.getElementById("RemoveStatus");
if (confirm("Are you sure you want to remove status?") == true)
{
button1.disabled = true;
button1.value = "Removing status...";
__doPostBack('RemoveStatus', '');
return true;
}
else
{
return false;
}
But for some reason I get an object expected error at the __doPostBack bit, I've clearly set the id, button1 gets populated too in debug, i'v tried passing button1.id and button1 too into the __doPostBack call but it wont postback and keeps saying object expected.
I have a simple user control with this code:
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="Pager.ascx.cs" Inherits="Pager" %>
<table style="width: 100%;">
<tr>[code]....
As you can see, the 2 buttons are wired to click events, which are defined correctly in the code-behind.Now, here is how I include an instance of the control on my page:
<uc:Pager ID="Pager1" runat="server" TotalRecords="100" DisplayItemsPerPage="true"
ItemsPerPageChoices="10,25,50,100" ItemsPerPageFormatString="Sessions/Page: {0}"
PageSize="25" OnPageChanged="PageChanged" OnPageSizeChanged="PageChanged" />
I noticed though, that the 2 buttons in my user control weren't causing a post back when clicked. The drop down list does cause postback, though. Here is the rendered HTML:
<table style="width: 100%;">
<tr>
<td id="ctl00_MainContent_Pager1_PageControls" align="left">[code]....
And, as you can see, there is no onclick attribute being rendered in the button's input elements. Why not?
EDIT,Ronnie, why are you so dumb??? <input type="submit" /> doesn't use javascript to post a form!
I am loading an aspx page into a div using jquery.load(). The aspx page loaded into the div has a datalist. Each datalist item has a linkbutton. My problem is that the linkbutton is not causing a postback though. Strangely, if I change the linkbutton to a button, it does postback. Also, when loading the page normally (not from a jquery.load event), the linkbutton performs correctly. What is it that causes the linkbutton to not cause a postback when loaded this way? And is there a better way to handle this?
View 2 RepliesI have an aspx page that has...
if (!IsPostBack)
{
PopulateBrand();
in the Page_Load. This PopulateBrand() simply populates my drop down. That works great and on post back it retains the value.
The problem I'm having is that there is also a link on the page that is posting back some parameters to this page. What is happening is that when this is clicked it's falling through this !IsPostBack section and wiping out my drop down values that I had selected and repopulating it.
How can I prevent this and just retain what I selected when this page is posting back to itself when the link is clicked?
Anyone knows how to do this? I have three distinct updatepanels on my page, and they're all unrelated. If possible, I would like the user to be able to interact with the other updatepanels while one is refreshing, or at least show which one is refreshing by only covering this with a div+animated gif.
View 6 RepliesI have an ASP dropdownlist with AutoPostBack="true" and I want to do some javascript client side which can stop the postback if necessary. However, I can't get it to stop the postback.
<script type="text/javascript">
$(document).ready(function()
{
$("#ddl").bind('change', function() {
return false;
});
});
</script>
<select id="ddl" onchange="form.submit()">
<option value="">Item 1</option>
<option value="">Item 2</option>
<option value="">Item 3</option>
<option value="">Item 4</option>
<option value="">Item 5</option>
</select>
so i have a lightbox in which pops up an aspx page with textboxes and two buttons (submit - disabled and cancel - enabled). I wanted to enable my submit button ontextchange. it works fine when opened separately (not as a lightbox) but when i let it run normally with the lightbox function everytime ontextchange gets triggered the whole page refreshes disabling the lightbox.
<asp:TextBox ID="textBox1" runat="server" OnTextChanged="OnTextChanged_AttributesEdited" autopostback="true">
protected void OnTextChanged_AttributesEdited(object sender, EventArgs e)
{
btnSubmit.Enabled = true;
}
now if i take out the "autopostback=true" it then will not trigger the the ontextchanged. was wondering if is it better if javascript will be the way to go for enabling the button or is there a way where i can prevent the postback when ontextchanged is triggered?
I have a gridview in an update panel with the following code to select a row, this in turn updates another updatepanel with details from the form record.
protected void gvMainGrid_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
//Make the entire row clickable to select this record
//Uses javascript to post page back
e.Row.Attributes["onmouseover"] = "this.style.cursor='hand';this.style.textDecoration='underline';";
e.Row.Attributes["onmouseout"] = "this.style.textDecoration='none';";
e.Row.Attributes.Add("onclick", ClientScript.GetPostBackClientHyperlink(this.gvMainGrid, "Select$" + e.Row.RowIndex));
}
}
I am manually binding the gridview from a database and don't want to rebind the grid just to highlight the row, but I can't seem to add any javascript to the onclick event, it seems to either show the GetPostBackClientHyperlink or the row highlight javascript.
