AJAX :: SelectedIndexChanged - Why Event Fired Within The Onblur - Event When It's Fired Anyway
May 3, 2010
In my current web application I have a listbox containing large number of elements. I have used an ajax listsearchextender to help the users in selecting the elements. I have set the autopostback property of listbox true. The application is working fine as expected in internet explorer. But in firefox while I am typing some text in search lable of listsearchextender the selectedIndexChanged event is fired and the page is posted back. So I am not able to selected the item properly using list search extender control. Can you please suggest me how can I stop the selectedIndexChanged event.
In our asp.net web application we load the dropdown list boxes in the page load. We than set the SelectedValue of each dropdown list box to an object from session. We have event handlers for many of the SelectedIndexChanged events of the drop down lists boxes, but these do not get executed when we set the selected value programmatically.
Someone else mentioned this is by design, and only when a user manually changes the drop down list selected index, will the event get raised.
I would think this is a common scenario of wanting the selectedindexchanged event handled when setting the selectedvalue/selectedindex/listitem's selected property, of a DropDownList. What is the suggested way to handle this? Is there a significant drawback of creating a custom control inherited from DropDownList that has the functionality of raising this event when changing the SelectedIndex or SelectedValue?

On my webform I have an AsyncFileUpload control. At first it is set not to be visible until two textboxes are filled. On the textbox_textchanged events the uploadcontrol is made visible. At that time the UploadedFileError event is fired.... why? The control is empty, so there is nothing to upload, but apparently it still tries to.How can I fix this?
I have AjaxCOntrol tool kit Tab control on the page.When I set the ActiveTabIndex proferty programatically in button click event ..like
tabContainer1.ActiveTabIndex = 1;
Then the serverside event 'onactivetabchanged' is not fired.I set the 'AutoPostBack' property to True.When I click on the tab, then it will fire the 'onactivetabchanged' event properly, But when set programatically it woun't fire.

I have one Button (Refresh Button), One ComboBox (containing DEV and UAT as its items) and a GridView on my asp page.
I am filling up my Grid with values from database on the ComboBox's 'TextChanged' event and Buttons's 'Click' event.
First time when page is loaded, there is no information in the grid, but when i choose DEV/UAT from the ComboBox 'TextChanged' event is fired, the grid is filled with the relevant data. That is what i want.
When i click the Refresh Button to refresh the data again, first comboBox's 'TextChanged' event and then 'btn_Click' event is fired.
I want then when a button id pressed only 'Click' event to be fired and not the ComboBox's 'TextChanged' event.
This causes alot of trouble for us in our application cause we use both ASP.NET-events mixed with jQuery and once you hook up a change event on any element every select (dropdown) gets this double firing problem.

I have an Ajax Toolkit Combo Box in DropDown Style (to allow user to enter custom value). The event SelectedIndexChanged and TextChanged works fine if the user select an item of the list of the combo box.
The problem is if the user enter a value that is not in the list of the item of the combo box, the event SelectedIndexChanged nor TextChanged are fired. Is there a way to "force" those events to be fired?
i have three textboxes in a page and one datagird and 1 timer control, i have 2 update panels.
i placed (all textboxes) in one update panel and i placed (data gird and timer control) in an other update panel, because i want to reset or clear all fields when cancel button is clicked so that update panel should be updated,and where timer control tick event is fired i rebind the gird or refresh the gird, i have done this and it works properly but problem is that when i am going to write some text in any textbox or i want to focus on any text box it should lost focus when timer control tick event is fired so how can i maintain focus, or even how can i get focus of current control and after firing of timer control tick event i should reassing focus of such control
I got a strange issue with Gridview in ModalPopupExtender. The OnRowCommand event of the GridView control does not get fired on the first clicking on the button. It will get fired on and after the second clicking.
I have a simple Textbox for entering password and the checkbox named Show passowrd beside it. Textbox mode is Password by default. These controls are in the table and I am using Update panel on top of the table. My application framework is 2.0 and I am Using ASP.NET 2.0 AJAX Extensions.
Now When i write some text in the textbox and check the Showpassword chekbox then the checkbox event is not getting fired. when Second time i click it then the event is fired and text in the textbox is removed and the textbox mode is set to the SingleLine. This functionality I am achieving by writing a code in the CS File.
When I remove the Update panel then the event is fired correctly everytime, but when usign Update panel and some text in the textbox then i have to check the checkbox twice for the desired functionality.
I have discovered something strange when using a ListView. I have a listview contained inside an uodate panel and everything works OK until I edit the editItemTemplate to use a LinkButton instead of a Button.When i use a LinkButton then the Page_Load event is fired.
I'm having trouble managing how to call upon databind from clicking on a row over an already populated repeater that will populate data regarding the row clicked TO another repeater on the same page.
I've succeeded doing that with postback, calling a jquery click event of that row, taking the data of the specific row and passing it onto a "Querystring" and after postpack, it will be pushed into a Session which the ObjectDataSource of the secondary repeater will recognize and populate the data tables accordingly.
The problem is, I must do it without a postback or in other words purely on client side.
I have parent page which loads child control which in turn contains DataGrid with template field and button has associated Click() event with it. Problem is that Click() event is not actually called at all. Sample code is below.
UserControl [Code].... Parent Page [Code]....
I put debugger into LinkButton1_Click event of user control but it never goes there.
