View 3 RepliesThis is what i am trying to do with asp.net updatepanel.i have button and a panel inside my updatepanel. when the button inside the updatepanel gets clicked i want to dynamically add new controls such as LinkButtons to my panel1 without full post back. Now when the dynamically added controls gets clicked it causes a full post pack and also not calling "LinkButton1_Click" event. i am sure i am doing something wrong here.

I basically want to show a dialog box with confirm or cancel options on it.
Confirm should allow the partial postback to take place, cancel should not. I have tried using a trigger and calling __doPostBack() as advised here but it posts back the full page not just the panel.
$('#buttonInUpdatePanel').live('click', function (event) {
event.preventDefault();
var item = this;
var title = 'Confirm';
var msg = 'Please confirm something';
var $dialog = $("<div id='myDialog'></div>")
.html(msg)
.dialog({
modal: true,
buttons: {
"Confirm": function () {
$(this).dialog("close");
__doPostBack('Button1', null); //tried this and .submit() on the button
//return true;
},
"Cancel": function () {
$(this).dialog("close");
//return false;
}
},
title: title
});
});
My UpdatePanel:
<asp:UpdatePanel ID="UpdatePanel2" UpdateMode="Conditional" runat="server">
<ContentTemplate>
<asp:TextBox runat="server" ID="TextBox1" />
<asp:Button
ID="Button1"
Text="Add"
OnClick="AddExtraVehicle_Click"
runat="server" />
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="Button1" EventName="Click" />
</Triggers>
</asp:UpdatePanel>
UPDATE:
I have changed the doPostBack to use the button ID now and commented out the return true and false lines. When I click the button it calls the confirmation dialog but when you click on confirm it appears to do nothing. I was expecting a call to the method AddExtraVehicle_Click but the breakpoint didn't trigger.
I found this solution to force full postbacks from within an UpdatePanel
<Triggers>
<asp:PostBackTrigger ControlID="controlID" />
</Triggers>
but my control is actually inside an ItemTemplate nested in a GridView. Therefore when my page loads, it doesn't find that control.
How can I force a full postback from my control (an asp:LinkButton) from within my GridView?
I have an input form on a page along with gridview and combo box. a user first select a filter combo box then click on search, to see a return values in a grid view format. then a user can enter new row once he / she cick add, i want the page to reload and the new inserted value to show in the gridview.

View 4 RepliesI have been searching the net and found no clean cut answer to my problem. I have an animated spinning gif, that is displayed within an 'UpdateProgress'. This gif is to be displayed when the page is posting back to the server and processing.
The animation will start to spin but basically stright away it stops. I have noticed that the file menu within IE is also frozen at this point, up untill the page fully refreshes. I have tested in firefox and safari and am recieving the same problems.
developing in visual studio 2010, framework 4.0, IE 7,8.
I have four textbox and a button in my page. After filling the textbox. When the user click save button. A loading image should be displayed. User should not feel that the page is postback to the server,Some thing like in facebook loading image.
View 5 RepliesBeing new to ASP.NET I have run into trouble building my own Whack-a-mole program. I think my problem comes from using Buttons, which by themselves send post backs to the server, making the software unusable. The looks are in place, making new buttons show up in the grid, in different places by random. However, when a button is pushed - the score doesn't change (which I feel is strange).
Not so strange is that the Button doesn't work since it sends post back to the server - reloading the UpdatePanel. I think I should use a different controller like the CheckBox and style it hard using CSS (which isn't a problem). Is this the correct way to go, or should I make use of JavaScript AJAX instead?
Note to self: This technique shouldn't be used in a public application since it put too much unwanted pressure on the web server.

I'm using Jquery UI and Autocomplete func.(Combobox) and I interested in this part.
$("<button> </button>")
.attr("tabIndex", -1)
.attr("title", "Show All Items")
.insertAfter(input)
.button({
icons: {
primary: "ui-icon-triangle-1-s"
},
text: false
My problem is when I use ASP.net, this button do PostBack, but I not need this because my list of items then gone. How can I override this behavior of button.
I have orders page. When user submit Order, I need to disable the button to avoid multiple transactions. I also have few validation controls on the page, so button should not be disabled untill page is about to be posted. I dont have any custom javascript for validation. It is just these asp.net validation controls. What is the best way to achieve that? I have spend about 2 hours on google and found various solutions, but nothing seems to work. Each has some issue. On button I add OnClientClick="return btnOnClick this, 'Payment');" Below is what gets called. Unfortunately if I disable button, it cancels post back. So I am calling dopostback and also adding few lines on server side to see which button caused postback. It works fine in IE8 and Chrome. But for Firefox on server side arg comes null. Any ideas what is wrong with my code? Or any other suggestions to do it in a better way?
C# Server side
string arg = this.Request.Params.Get("__EVENTTARGET");
if (arg == "Payment") { this.ProcessPayment(); }
Button
<asp:Button ID="btnSubmitPO" OnClientClick="return btnOnClick(this, 'Payment');" runat="server" Text="Submit Order" ValidationGroup="G" />
alert(group);

I have created a listbox that the selected items would remove by using javascript once I clicked on a server button. Below is the code I'm using
<asp:button id="btnSelected" Runat="server" CssClass="InputFormObject" Text=">" ></asp:button>
<script language="javascript">
function removeOptions(selectbox)
{
var i;
for(i=selectbox.options.length-1;i>=0;i--)
{
if(selectbox.options[i].selected)
selectbox.remove(i);
}
return false;
}
</script>

We are having a button in an user control where this button is surrounded by update panel.
We are using above user control twice in a single page, then we will get 2 buttons in that page.
If we click on any of the button then page gets post back twice. Can some one let me know why it is happening and how to fix this?
I am looping through all the posted data on my website and grabbing the values, this will then be used later on. The user is going to put 2 radio buttons on the page, one with a correct answer and one with an incorrect answer. I need to know how to see if a Radio Button is checked or not based on the posted data.

I basically have a web app where the user enters some form info in Page1. This info is submitted and a SQL database is updated. The user is directed to Page2.
Page 2 contains a summary of info submitted in Page1, a PRINT button, and two UpdatePanels. Each UpdatePanel contains a ListView where the user can add, edit and remove items. Once the user is happy with the page, they click PRINT. This takes them to a printer-friendly page with NO on-page navigation.
Once printed using the browser print button, the user clicks the browser back button. In this case it is always IE8 running the pages. When you return to Page2, the content of the ListViews in the UpdatePanels looks like the first step when Page2 was entered from Page1. All work done on Page2 from that intial point is not there. Click the browser refresh button and the entire page will load.
Why does this happen? When the user clicks the browser back button in the printer friendly page, I need the screen to show Page2 with all the info from just before the PRINT button was pressed.
I can provide code, but initially thought it would confuse/clutter the post.
I searched google and found asynchronise post back trigger is used if we want update panel to post back on some event of control if it is out side the update panel. Than what is purpose of post back trigger ?
View 2 RepliesI'd like to programmatically force a full page postback to occur after an event is fired by one of the child controls. I can't add any triggers to make this work so it will have to be done via code.
View 2 Repliesi am using vs2008. 1/ i am placed a datagrid control, a textbox and a server side button are inside the CollapsiblePanelExtender.
2/ The collapsible panel Extender placed inside the updatepanel.
3/ outside of updatepanel i have another button("next page") to redirect to next page.
When the page is loading, i am displaying all the records in datagrid. For an example 100 rocords. if i entered some values in textbox and click the button it fetches searching result based on inputs and displaying it in datagrid (for example searched result 20).
Now, I click the button "next page" it redirect to next page. if the user click the browser back button, i need to keep the datagrid to show only searched result. but Instead of that, it displaying all the records(100 records). how to resolve this?
How do force full page rendering in async call process?
