I had validate the data when user click save button, an alert box will pop up when error occurs.
[Code]....
But when the user click confirm button, it will auto postback to reload the page that made my page distored (may conflict the css that move to left hand side)I had insert "return false;" in the statement, but it doesn't work.
Is there any way to disable the postback ?

I have written a javascript code for handling the password functionality. The scenario is: when user wants to change the old password, he cannot fill the same old password again. I have written the code. But even the simple alert of blank textbox is not working. See the code for reference:
Javascript code:-
<script type="text/javascript">
function ltrim(str) {
var reg
reg = /^s+/g
return str.replace(reg, "")
}
function rtrim(str) {
[Code] .....
aspx code:-
<tr>
<td class="auto-style1">Old Password</td>
<td class="auto-style2">
<asp:TextBox ID="txtOldPassword" runat="server" TextMode="Password" class="txtcareer"></asp:TextBox>
<asp:RequiredFieldValidator ID="reqtxtOldPassword" ControlToValidate="txtOldPassword" runat="server" ErrorMessage="*"></asp:RequiredFieldValidator>

Why this is not working...
i have dropdownlist with autopostback=true,
written onchange event for confirm popup and SelectedIndexChanged event also exists.
req is if confirm returns true then only postback should happen else not
instead its not atall doing postback whether it returns true or false.
i managed to get it work by forcing postback by using __doPostback()
For some strange reason an alert dialog with the text title "Message From Web page" and message "-" displays when posting back a for with validation. There are no custom validation scripts that display an alert window. I am debgging javascript using IE development toolbar? Is it possible to break into the code that displays the alert box? so far I have been unable to do so.

There is a calendar control on my page and I need the selected date to remain selected after I hit this button. Right now if I hit the button it refreshes the whole page and sets the calendar's selected day back to date.
How to disable postback on page..
View 2 RepliesI have a master page containing menu items and if i click on any menu item then postback happens(it's not an asynchronous postback) that page loads in the content area. Now, if the page has taken some time to load and the user again clicks some other menu, then at some cases, it is crashing. So what i want to do is when postback is happening, I want to restrict the user to click anywhere on the master page or content page. We have achieved this on asynchronous postback.... But cant find a solution during postback.

I am a newbee with c# and asp.net.1- I have a grid view which is with name of GRIDVIEW12- GRIDVIEW1 is bound to dataset on PAGELOAD
GridView1.DataSource = dt1;
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?
View 4 RepliesI've searched high and low for some resolution to this problem. Hopefully someone here can explain!!I create a usercontrol that uses .NET web controls, but I want to create a smoother user experience by avoiding full postbacks, so I write some JQUERY to capture click events on the client and in this way do the processing without going back to the server.
$("#tblLedgerEntries :checkbox").click(function () {
var value1 = $(this).closest("tr").find("td.invoiceAmount").html();
var value2 = $('#<%=hdnTotalToPay.ClientID%>').html();
CalculateTotalPayable(value1, value2, $(this).attr("checked"));

I have an input box that I don't want postback to occur on someone striking the enter key
I want the javascript event to take place instead.
<input
type="text"
id="addressInput"
onkeydown="inputenter()"
autopostback="false"/>
function inputenter() {
if (event.keyCode == 13) {
seachLocations();
return false;
}
else {
return false;
}
}
I have an application that is supposed to accept checks. The user has 2 radio buttons. The first radio button has a drop down list associated with it which contains the masked numbers of their previously used checking accounts.
The second radio button has three text boxes and an image of a check associated with it.
When a user hits this page, the three text boxes and the check image associated with the second radio button are disabled. Then, if the user decides he/she wants to use a new checking account, they can click the second radio button and that fires the Javascript that enables the three check boxes and the image of the check associated with that second radio button. If they click on the first radio button, it will re-disable the text boxes and hide the check image associated with the second radio button.
The problem happens when I do my server side validation. After validating all text fields, if there is a problem, I just fall out of the bottom of the code, the page posts back and the labels above the offending text fields show an error message.
One caveat: The Javascript that is supposed to fire on the OnClick event for the first radio button fires and the text fields for the second radio button are disabled. The user can click on the second radio button and the fields will enable, but this is very clunky.
Here's the enable code where I am injecting the Javascript:
Private Sub JavascriptInject()
Dim sEnableControls As String
Dim sDisableControls As String

I have a div where I put a lot of stuff on runtime to construct a chart. The user should be able to copy the chart to another div (innerHTML) and then make som adjustments to the original div, which causes a postback. Of cours the cloned div comes back empty.
So I'm thinking of putting the entire innerHTML in a session variable at page_unload, but then I run into the validation problem. I've tried using a hiddenfield as an in-between control, but it's the same, and it seems you can't use the CausesValidation on that control. I've also tried a regular asp:textbox, but the CausesValidation doesn't have any effect.
How to do this? Or any better way all together on the copy-chart issue?
How do I disable a button in an ascx page? I know how to do it on an aspx page with:
btnSave.Attributes.Add("onclick",
"this.disabled=true;this.value='Please Wait...';needToConfirm=false;" +
ClientScript.GetPostBackEventReference(btnSave, "").ToString());
But the ClientScript function is not present in the ascx page.

View 4 RepliesI want to do is to pop-up a msgbox (or confirm box) only if an item has been modified on the page therefore when session(modified_products)= true.
This is my code as of this moment

Now I already figured out that msgbox doesn't work in ASP.net (which is kind of stupid, why put it as a function if it doesn't work). So I need to replace MsgBox with something that will give me the same functionality.
