C# - Page Enter Key Causing Post Back?
Nov 17, 2010
I have an aspx page that postsback when it should not. there are two text boxes, two listboxes and two buttons on the page. if at any-point the enter key is pressed the first button is given focus and "clicked" resulting in a loss of selection within the listboxes.
How do I disable this? there are tons of tutorials on how to capture the enter button and execute a method but I could find one on how to simply disable the neat "let me grab the first button I find and click it" feature mentioned above.

I have a master page which includes a search textbox and a button which posts back to another page. The controls are defined as follows:
<asp:TextBox
ID="SearchTextBox"
runat="server"
style="margin-left:
0px"
Width="170px" />
<cc1:TextBoxWatermarkExtender
ID="SearchTextBox_TextBoxWatermarkExtender"
runat="server"
Enabled="True"
TargetControlID="SearchTextBox"
WatermarkCssClass="watermark"
WatermarkText="Search Name" />
<asp:Button
ID="SearchButton"
runat="server"
Text="Search"
PostBackUrl="~/SearchPage.aspx"/>
The problem is that for any other TextBox on the page which is using this MasterPage, for example the login page, if you type your user name and password and hit Enter, The page is redirected to the SearchPage. If you click on login buttton everything works fine. How do I make sure hitting enter on the page in any other text box does not post back to SearchPage.aspx?

Being 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 a search field (text box) at the top of my page. When you type something, and press enter, the page navigates back to the previous page? What I want it to do is act as if I clicked the Search button.

I have a page that I am adding user controls to the bottom of the controls each postback. The User Control has a textbox in it and the focus needs to be on this newly created control textbox each time. It all works almost perfectly however when there are too many controls to fit on the page, because I set the focus to the textbox the bottom of the page is set to the textbox that has focus not the very bottom of the page. I have a submit button below this which ends up below the page limit. How can I set focus to a textbox but still scroll to the every bottom of the page to show the submit button.

I have an HTML text box and button:
<input type='text' onkeypress='onEnter(this, event);' />
<input type='button' />
This works fine (when you push enter, another function is called) unless the page has a FormView control on it.
In this case, pushing Enter in the textbox above attempts to validate the form on the page. It will still correctly call the onEnter function, but I need the Enter keypress to not cause Validation of any other forms on this page.
All input fields in the FormView are part of a ValidationGroup, but this doesn't seem to affect anything.
What is the best way to keep the .Net validation from happening when I push Enter in my HTML textbox?

I am writting an application that displays 3 visable text boxes and 1 hidden text box and one hidden button.
My application sets focus to the hidden text box.
The input comes from a barcode scanning gun which gives the "enter" command after the scan is complete...this essentially clicks the hidden submit button which moves the text from the hidden text box to the currently active visable text box.
To start the application does some verification on what was scanned then gives the user feedback on what was scanned then enters it into SQL.
My problem comes with the last scan...the page does not actually post back to give the user the neccessary confirmation before commiting the info to SQL and resetting the form.
Is there a way to either do somethig after the page has been rendered or do an additional post back somehow before calling the commit and reset functions?

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 am using ASP.NET 2.0 with C#(No AJAX) in my project. In a particular web page, when the a button is clicked, some server intensive C# code runs before the same page is displayed again with the results. While code execution happens on the server in response to Button_Click event, a blank white page is shown to user on his browser in between post backs. How do i show a message in this case, that the processing is still going on and ask the user to wait? I have used javascript to show a message on page unload. But this message is also erased when the page is posted back to the server and the user sees a blank white page on his browser. How do i avoid this white page? Is there a way to show a message in the blank white page? How do i show a processing Message while the page is loading upon on Post Backs to the same Page.

I have a button like this:
<asp:Button ID="btnSave" runat="server" ClientIDMode="Static" Text="Save" OnClientClick="return ConfirmSave();" OnClick="btnSave_Click" />
If I write my client function like the following, it works as expected:
function ConfirmSave()
{
return confirm('Confirm?');
}
But I should check, inside the function, for the confirm result, like this:
function ConfirmSave()
{
if (Page_ClientValidate('validationGroup'))
{
var conf = confirm("Confirm?");
if (conf)
{
$('#btnSave').attr('disabled', 'disabled');
}
return conf;
}
else
return false;
}
Doing this, the page postback but the server click event doesn't fire.
