how to force textchanged to work onblur ??
Actually i want to do tabbing in a Gridview rowwise i have done it.
Problem is that i have done by using onTextChange event now whenever I have to tab away.
I have to text and then enter the tab, then only it works and my requirement is that tab should be done for without entering the text also
So as i'm having all the code i want to forcefully do this onBlur event. ???
You could probably write just a little javascript(using jQuery) so that when the onblur event occurs that the txtChanged event is called on the client side.
Something like
$('#IdHere').blur(function() {
$('#IdHere').change();
});

Improve this question
In asp.net web application, I am having one textbox and one button in UI. And I set textchanged event for the textbox.
Textbox_TextChanged Event:
When this event fires, web page will display js popup through script manager functionality.
Button Click Event:
When this event fires, it will clear the textbox value.
Now Issue is,
When I write some text in textbox and without focus out of the textbox, I clicked on Button to clear the values. But Visual studio firing Textbox_TextChanged Event. I need to fire only Button Click Event not a Textbox_TextChanged Event.
Note : Here both element's are asp controls.
Please help me to get out of this issue.
Text_Changed and Button_Click are server events for server controls. That means posting a new http request to the server to get a new http response. By the time these events finish you're looking at an completely new html DOM created from a completely new instance of your Page class. The existing html DOM was destroyed so the new one could take it's place. This is rarely a good idea for something like Text_Changed, that might need to fire repeatedly and respond as fast as a user can type.
You probably want to re-think these to happen entirely in javascript; don't even use the ScriptManager. If you're writing C# or VB.Net to respond to these events, you're in the wrong place. Unfortunately, javascript doesn't have a direct equivalent to Text_Changed, and you'll need to look at the onkeydown, onkeyup, onkeypress, onpaste, oncut, and onmouseup events, any of which might cause text to change.
On a UI/UX note, it's also rarely a good idea to push a pop up in front of a user on any possible text change. Users tend not to like it when you interrupt them while they're typing. You might instead want to look at events like onblur and onchange for the popup, and use some other visual indication that things are not right while the user is still working in the textbox... something that won't immediately interrupt them.
Find the textbox control that youre working with and go the properties window (press F4) in visual studio when on this.
Find the lightening icon and click it,
next find the Text Changed event and remove the method \ sub name from this field.
Alternatively in your ASPX markup, you will probably find the event there too...
Also, in your code behind you'll have something like this
public sub Text_Changed(...) Handles MyPage.Text_Changed ' (im plucking this out of the air as its been a while since ive worked with VB)
You can remove the Handles bit and that would also do it for you

Post-Redirect-Get with ASP.NET
I have a button on my form. Inside the button_click event I insert some data to database. If I click that button and then refresh the page, it seems the button gets clicked again because I find the same data inserted to the database twice. Is there a way to prevent this?
You have to use PRG patern to avoid this problem.
When you refresh the page your last request(either get or Post) resubmitted to the server again.
Solution: In the click event use this at the last
Response.Redirect(#"~\page.aspx");
after insert you can redirect to the same page using Response.Redirect(Request.RawUrl)
this will prevent the problem

Best way to detect when a user leaves a web page?

What is the best way to detect if a user leaves a web page without first saving?
I have searched before I posted this question, but I haven't found related topics to deal with ASP.NET (I have controls DropDownList, ListBox, TextBox....)
I would use the JQuery serialize method to save off the form's state in the page's OnLoad event. Then serialize the page again in the OnBeforeUnload event. If the values are different, then the page has changed. You'll have to add a flag to know whether or not the page is unloading because the "Save" button is being clicked. If the values are different and the user didn't click "Save", then display the "Do you want to save before leaving?" box.
One very simple way is to do it the StackOverflow way:
http://www.jonstjohn.com/node/23
Basically it boils down to setting a method to be called in the onbeforeunload javascript event.
I tried to ask this question on the jquery tools forum, but didn't get a response, hopefully someone here can help.
Question:
It seems the onClick event does not get fired when user is already on current tab, I think that make sense for most cases. However, in my case, I do want to capture the onClick event even when the curent tab is already the selection.
Is there a way to do this?
Thanks!
You can always bind the onClick event to the anchor tags themselves rather than to the tabs events.
