I have a textbox, on pressing the ENTER key within it, a function should be called with the value in it.
This requires that one of keypress,keydown or keyup to be handled on the server side.
I find that only client side implementation are being followed.

View 3 RepliesSo I've got a databound grid view within a UpdatePanel.
the user can change the data within the gridview then click a save button to update the data within the database.
However in order to know which rows have been changed I have a textChanged event associated with each textbox, but the event isn't being fired.
Here's the ASP code:

I am developing and Asp.net website. Occsionally I will have to display A Java Script dialog box. The dialog box will have two buttons on it. One labeled "Proceed" and the other labeled "Cancel". Then I need two Java Script methods to respond to which button was pressed. So I suppose my java script methods to handle the button press might look like the code below.
Anyway, I don't know how to invoke these methods when the dialog button are pressed.

I noticed that the asp:Button for example will work without javascript enabled in the browser. However any other control with an "OnClick" or "OnServerClick" event must use the javascript_doPostback.Are there any controls besides the Button that don't need to use javascript?I want to know because I want to be able to style the Control however I want without it looking like a button, and I want it to still work without the user having javascript enabled.
View 2 RepliesThis may sound silly, but I need to find out how to handle an Update event from a GridView.First of all, I have a DataSet, where there is a typed DataTable with a typed TableAdapter, based on a "select all query", with auto-generated Insert, Update, and Delete methods.Then, in my aspx page, I have an ObjectDataSource related to my typed TableAdapter on Select,Insert, Update and Delete methods. Finnally, I have a GridView bound to this ObjectDataSource,with default Edit, Update and Cancel links.How should I implement the edit functionality? Should I have something like this?
protected void GridView_RowEditing(object sender, GridViewEditEventArgs e)
using(MyTableAdapter ta = new MyTableAdapter())
ta.Update(...);

I am a bit new to the asp.net/jQuery game, and I seem to be having difficulty. I am using colorbox to make a modal window popup, and I want an upload picture form on that modal window. I have a button to open up the add photo form:

<script>
$(document).ready(function () {
$(".addpicture").colorbox({ width: "50%", inline: true, href: "#page1" });

I have a Gridview displaying Titles.I would like those titles to be LinkButtons that would cause event to update an AJAX UpdatePanel containing details about the Projects.I would not like the Gridview to be in the Ajax UpdatePanel and refresh on every click, rather just refresh the UpdatePanel.
View 2 RepliesI am trying figure out how I handle events in a dynamically added user control. Basically I can add user controls dynamically to my form (I am then storing them in an ArrayList in a Session variable that I use to reload them on my Page_Load). Each control has a button on it. However, whenever I click the button, the event never fires (code is never reached). I assume it has something to do with the control being dynamic, and when I click a button, it goes out of scope, and when I reload it something is lose in the event handling.
Here's my code for adding a user control:
Code:
Protected Sub Page_Load(sender As Object, e As System.EventArgs) Handles Me.Load
Dim alContact As New ArrayList
If Not IsPostBack Then
' Dummy controls for testing
Dim oContact As New ASP.ContactControl
[Code] ....
I have an aspx webpage in which an user control is added dynamically as follows:
UserControl testUsrControl = LoadControl("TestUsrControl") as UserControl;
testUsrControl.ID ="test";
Then I tried adding an event handler of user control inside aspx like below:
testUsrControl.Drpdatafield_SelectIndexChanged += new EventHandler(this.Drpdatafield_SelectIndexChanged);
But this line is giving error at **testUsrControl.Drpdatafield_SelectIndexChanged **. The error is "Drpdatafield_SelectIndexChanged" doesn't exist in UserControl.How can get the testUsrControl's events inside aspx page dynamically.
Is there any way to handle clientside events for Ajax Control Toolkit controls? for example, is there any way to handle HoverMenuExtender's onmouseover event, make some operations, and let the control to continue it's execution?

View 1 RepliesI have a requirement that user can input HTML tags in the ASP.NET TextBox. The value of the textbox will be saved in the database and then we need to show it
on some other page what he had entered. SO to do so I set the ValidateRequest="false" on the Page directive. Now the problem is that when user input somthing like :
<script> window.location = 'http://www.xyz.com'; </script>
Now its values saved in the database, but when I am showing its value in some other page It redirects me to "http://www.xyz.com" which is obvious
as the javascript catches it. But I need to find a solution as I need to show exactly what he had entered. I am thinking of Server.HtmlEncode. Can you guide me to a direction for my requirement

View 4 RepliesI have been tasked with designing a scheduling system to fit into an existing application. At present I have a SQL Table - Tasks which have a StartDate and EndDate column.
I have a requirement to set the Task as a recurring task i.e. Replace server backup tapes every day, or, Order more stationary once a month.
I am lost on how to design this. I can't seem to find a proper example on the net. can someone point me in the right direction.
I have a page with 2 Controls, a ListBox and a DropDownList.
In the DropDownList you can select a PLACE.
In the ListBox you can see all DOCUMENTS for the selected PLACE.
If you select a DOCUMENT, the program does a redirect on the selected DOCUMENT.
So, there are an AutoPostBack and an Event (if you select another Item) on both Controls.
The problem is: If I select a PLACE, then I select a DOCUMENT (the pdf document is opened), and then I go back on the page and I want to select another PLACE, the program doesn't select another PLACE, but opens the old DOCUMENT, because there are 2 Events, one to change the PLACE and one to open the DOCUMENTS.
Can I give a priority at the Events?

Just I started learning MVC pattern, of course i am learning it from Microsoft's website.Just i want to gather quiz information from the experts. My understanding is (correct me then and there)
1 ) MVC does not support server side events, but supports client side events. If it supports client side events, I need html page with jQuery/Javascript (view), but most of the example I absorbed is to display the information(model) in view, I did not see any client side event handling happens in view.
2) Except ViewState and controlState, MVC supports Sessions, Application State management, Cache management.
3) When request goes to MVC engine, the routing module routes the request that is picked up by the controller. The controller in executes the appropriate action and returns the appropriate view.
