I am creating a products page, it will display some products based on certain conditions.
In front of every product i have placed a button dynamically, on click of this button some event will be fired (i will add that product to shopping cart).
Now what i want is to preserver the button controls even after the postback and how will i get to know that which product's button is clicked?
I'm using ADO.Net code to access and update the data from the database. I'm using GridView for presentation. I wish to preserve old values of all the columns while updaing the records.
I'm using Code behind and not d Data Source controls. I wish to list the old records once record is updated.
I am using ajaxcontroltoolkit's htmleditor. I am trying to submit programmatic code like javascript,c# and css styled tags.
When I enter the code using the pre tag. HTML editor is not able to preserve the line breaks inside the pre tag.
Is there a way, I can do that?
I have a script that runs during the Page_Load() event which checks a database table to make sure that the user is still owns the lock on the page. If they no longer own the lock, I disable all the controls on the page and display an
error message.My thinking was that by disabling all controls during Page_Load() I could prevent any PostBack events from occuring. For example, I have a button on the page called "Save and Quit"
I have problems with gridview that has command button in it. The command button (when clicked) should redirect to another web page, but instead of doing it only does postback on current page.

I have a GridView with a couple of buttons (asp:Button) in it (last row). Both of them have a CommandName attribute on them and this is handled server side in a grid_RowCommand event handler. Now, this works fine. However, I need to add client side code (Javascript/jQuery) to disable the two buttons when someone clicks on or the other. This is to prevent the user from double-clicking and creating potential havoc.
The way I have done this is by adding OnClientClick on both buttons which calls a javascript function that uses jQuery to disable the two buttons. This works fine, it's just that the page doesn't post back and so the RowCommand event handler never fires.

I have a GridView within an UpdatePanel - <asp:UpdatePanel ID="UpdatePanel1" runat="server" ChildrenAsTriggers="true">
Without listing any Triggers, I get a full postback when I visit a particular row within the GridView and click the 'Edit' button for that row.
However, if I enter the following trigger...
<Triggers>
<asp:AsyncPostBackTrigger ControlID="GridView1" EventName="RowEditing" />
</Triggers>
...I get an async postback when I click the 'Edit' button for a particular GridView row. This is what I want. In fact, I also get an async postback if I then click the 'Cancel' button for that GridView row which appears after having clicked the 'Edit' button.
However, if I instead click the 'Update' button that appears after having clicked the 'Edit' button, I get a full postback. I have tried almost every GridView EventName
I can find to add to the <Triggers></Triggers> section to get a click of the 'Update' button to result in an async postback, but with no luck.
What EventName should I use in the <Triggers></Triggers> section to get a GridView to do an async postback when clicking the 'Update' button for a particular row?

I have a button that has an server side event onclick that when triggerd adds javascript code to the onclick event and changes the text value.
On the second click only the javascript code is triggered who changes the text value of the button and sets the client side onclick event to null, while resoponding wiht an return false to counter the postback.
On a real postback of my page the button text value is set back to the latest value given by server side code, it does not keeps its properties set by the javascript client code.
I think this is normal as the button is not posted back or something like that. How could I keep its client side changed properties and let the server side know about it ? Can I modify the viewstate or something similar .... ?

I have two text boxes txtBox_Input1 & txtBox_Input2 which Iam trying to validate on a postback when a button is clicked.here is the code:
[Code]....
The issue is that its causing an unhandled exception. When i debug by applying breaks and i check the validatorControl.ControlToValidate the IsValid property is false and then i try to cast the ControlTovalidate which is a string to a TEXTBOX and try change the border properties i get NullReferenceException, i.e. errortxtbox control is null at step '3->'. I check the validatorControl and I have all the attributes there but somehow its not casting the controlToValidate string as an appropriate texbox control to errortxtbox.

I have a Formview that is bound to an SQL database, and in its item template I have added an image button.
That image button on selection needs to postback a primary key Value (VoucherID) to be used in a second control on the same page. In VWD I can get it to post back but I can't get it to post back with the VoucherID parameter.
I can easily get it to send a querystring parameter, but I don't want to do it this way.
i have a button that will check whether textbox1.text is empty or not. I have put a if function inside the btn_click event and look like this

May i know what shpuld be the code inside the else statement if i do not want the button to create a postback and just do nothing?
My current structure:
1. An asp.net radio-button list with autopostback = true. The radio-button list has 2 items - Yes and No.
2. An asp panel that has 2 textbox.
Current behaviour:
When the user clicks on the radio-button list (i.e. Yes), the panel is made visible.
My clients wants the same functionality without the page refresh (i.e. the postback).
when i click on button then postback happen but i stopped the postback. my code is follows.

I've some really strange behaviour with a simple ASP.NET Button. Here's my code:
[Code]....
For some reason the first time I click this button, the code is beeing fired. When login credentials are wrong, a message shows up. THen, the user inserts the right credentials. After clicking the 'cmdLogin' button, nothing happens and the old (wrong) values are beeing filled in inside the textboxes. This behaviour occured to me after switching to ASP.NET 4.0.
(Using ASP.Net 2.0 on Visual Studio 2005, coding in C#)I write in the hope that someone will be able to provide a clue as to how I might best overcome this issue:I've got a form with 2 RequiredFieldValidators, and 2 buttons. Button 1 has 'CausesValidation' set to 'False', and populates some of the other fields on the form from the database (via a postback).Button 2 fires the validation, then if the form is valid brings a javascript popup confirmation box and then, if true, it puts the data in the form into an email.All this is working fine. However......My problem is this: If I press button 2 with my required field(s) empty, the form quite correctly refuses to submit, and highlights the appropriate field(s) with a red *.But: if I then press button 1 (my populating button) it DOES NOT FIRE until I press it a second time!Code snippet follows (markup only - I will of course post code-behind if nec. but I don't think it is)
<script type="text/javascript">
function ConfirmSubmit()
