how to force textchanged to work onblur? - asp.net

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 hav to do tabbing
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();
});

On text change event firing in local but not in test server

I have written code in ontextchange and made autopostback=true. When we give text in textbox and click on tab...on text change is firing and giving the alert. But when we give text in textbox and click directly on button, It is not giving any alert and directly saving with empty data...(We have written code to check duplicate values in ontextchange event).
Please help me on this..
If I understood you correctly, It seems your button click event is taking precedence over your onTextChange
I suggest you to disable your button and enable it in OnTextChange event, So that both of your requests will not overlap.

ASP.NET Textbox TextChanged and Button OnClick event interaction?

I've got an ASP.NET application that I'm accessing through Google Chrome. On a particular page I've got an asp:TextBox with a OnTextChanged event that recalculates a few other fields on the page. I've also got an asp:LinkButton with an OnClick event that saves the changes to the database.
I was facing a problem where the user left the TextBox by clicking on the save button. The button was firing before the TextChanged event so the changes were not being captured in the save. I fixed this by duplicating the TextChanged logic at the beginning of the save method. Did some testing before I committed these changes and everything was working fine.
But now my tester is facing a different problem. When he changes the text field and clicks the save button, the OnTextChanged event is firing to update the other values on the page but the OnClick event for the save button is not firing at all. He has to click the save button a second time to get the OnClick event to fire. I tested the same functionality on my machine and it's still working fine for me. He and I are looking at exactly the same page in the same environment with the same database. I had my tester clear his cache etc. The only difference I can find is that my Chrome version is "14.0.835.202 m" while his is simply "14.0.835.202".
Are there any known issues with Chrome and ASP.NET where event firing can be non-deterministic or something? Anyone have any other idea why this might be happening? Thanks for your time!
I believe this is a known issue.
One option is to disable the button (client-side) when the user is typing in the TextBox, and enable it after the TextChanged event completes.
Another option is to remove AutoPostBack="true" and use AJAX instead.

ASP.NET Adding OnClick event to asp:DropDownList control

I need to add the OnClick event to asp:DropDownList control, due to the existing events don't satisfy my current needs.
Is it possible to achieve this?
Thank you very much.
What reason do you have for wanting an OnClick event on the DropDownList control? If you were to implement an OnClick server-side event on the DropDownList the user would never be able to select any of the list items. This is because in order to fire a Server-Side OnClick, a postback would be required. I.e. the user would click the DropDownList, a postback would instantly occur and they wouldn't be able to select a value.
It sounds like a case of trying to fix the wrong problem, however you could probably try and use the "onclick" JavaScript attribute and handle whatever you're trying to do using client side script and AJAX?

How do I force a full postback from codebehind?

I'd like to programmatically force a full page postback to occur after an event is fired by one of the child controls. I can't add any triggers to make this work so it will have to be done via code. Thanks.
Sorry, don't understand. By the time an event in codebehind is running, a postback has already happened.
If you mean a client side event then setup OnClientClick to call what is returned by the following after your other client side functionality:
Page.ClientScript.GetPostBackEventReference(control, "")
(It will be something like __dopostback)

How can I trigger a server-side event from a client-side event?

Short version
All I need is that, in a ModalPopUp, when the DoubleClick event of a ListItem fires, the click event of my OK button should be executed.
Detail
I have a ModalPopUpExtender, which hosts a user control. The user control has an OK and a Cancel button. Along with that, it has a dynamic ListBox added to it. So far, I've considered the following possible solutions:
Use Ajax.Net. But, I cannot afford to have a WebMethod.
Use a ClientScriptCallBack. This will need a lot of JavaScript, since I have made almost every control dynamic.
Is there any other way apart from using an UpdatePanel?
Have a look at this way using __doPostback
calling a VB.net function from javascript
