I have a asp.net app that I want to disable the buttons as soon as they are clicked in order to prevent multiple submissions. I'd like to use jquery for this as the site already liberally uses it anyway.
What I've tried is:
[code]....
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.
In my code, I cannot use a radiobuttongroup due to formatting constraints. This is a page where the user can update the data. So I have
<asp:TableCell ID="TableCell1" CssClass="answer" runat="server">
<asp:RadioButton ID="PatientYes" GroupName="Patient" runat="server" />
</asp:TableCell>
<asp:TableCell ID="TableCell2" CssClass="answer" runat="server">
<asp:RadioButton ID="PatientNo" GroupName="Patient" runat="server" />
</asp:TableCell>
If I have the case where one button is set when the page is displayed and the user changes to the other value, BOTH are coming back as TRUE. How can I just get the value selected by the user?
watch here:
- Create a gridview with AllowPaging and AllowSorting = true
- On page load, I bind it to datasource (in my case a webservice)
- On gridview's rowcreated event, I dynamically add image buttons on the header of the grid for sorting (up/down arrows). On header I have column name and the image. I removed the Column name default sorting link. So user can now only click the image button for sorting.
- Call sorting method
This works perfectly fine without AJAX. The paging, sorting works fine. Also when I apply AJAX the paging works fine. But the sorting is doing a full post back instead of partial postback.
I have my gridview within UpdatePanel and Triggeres is set on gridview sill it doesn't work.

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 am using jQuery tabs and an ASP.NET listview to display and edit some information. My problem is that when a user inserts a new record in one of the listview items my jQuery tabs go back to the first tab. Is there a way to keep track of which tab I am on or keep it from resting on post back?

While i tried my own but the problem is that on post back it come to same condition. I have implemented the add remove functionality by using the jQuery but the problem is that on post back it come to same condition so i want a good solution for this ow should i implement this so that on post back it retain it's value please ris me off from this issue.I found some solutions for this on Google that i should make some other class which will extend ListBox base class but i couldn't understand that and how should i code for that so please explain me that code if possible.

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 have an asp.net page "demo.aspx", that has a normal link called "Demo Link" which uses jQuery Thick box. The page that is wrapped inside the Thickbox is "target.aspx", that has a button "Demo Button" and a label.
If I click on the Demo Link, it show the "target.aspx" wrapped inside the Thickbox nicely. However, If I click on the "Demo Button", Thickbox is disappeared, "target.aspx" is not wrapped in Thickbox anymore, it is displayed like a normal asp.net page.
Here's the mark-up code of demo.aspx:
<a href="target.aspx?height=600&width=800" class="thickbox" title="">Testing Thickbox with Post-back</a>
Here's the code-behind of target.aspx:
Protected Sub btnDemo_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnDemo.Click
lblDemo.Text = "Hello World!"
End Sub
How do I keep target.aspx in the Thickbox after the post-back of itself?

I have a dynamic data bound drop down list, when the user selects thier selected item I have to use the autopostback feature.
Problem is: when the page comes back it is at the top of the page not where i have the control.
I don't really need it to focus back on the dropdownlist but to scroll to it, I want to do it in the code behind.
Any "New" ways to do it, I mean new as in code from like 2010 instead of old code from the early days.
I really don't want to use Page.Register new Script...... code if I can avoid it.
What would be cool is a ScrollToControl() Function for my code behind that worked but didn't register script.
I have a very odd and disconcerning problem. Just recently a page where I have 1 textbox and a buttoon has ceased to work.
When I look at the post coming into the PageLoad, the pageType is "POST", but the Page.IsPostBack is false!! and the textbox (which had content) is empty.
I have stripped all AJAX script out, so I have a very vanilla page (in a master page) being served.
The pages is

View 4 RepliesI am trying to disable buttons in an aspx form. This works:
btnSave.Attributes.Add(
"onclick",
"this.disabled=true;this.value='Saving...';needToConfirm=false;" +
ClientScript.GetPostBackEventReference(btnSave, "").ToString());
But there are two buttons on the form and I want to disable both. This does not work:
btnSave.Attributes.Add(
"onclick",
"this.disabled=true;this.value='Saving...';document.getElementById(<%=btnDelete.ClientID %>).disableneedToConfirm=false;" +
ClientScript.GetPostBackEventReference(btnSave, "").ToString());
I'm trying to write code that will disable submit button (or all submit buttons) on the page to avoid double postback.I thought of generating my own postback javascript function (and inject postback javascript using GetPostbackEventReference) but maybe there are some better ways to do this? Or maybe there is some other way to avoid double postbacks?
