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 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 have a pretty simple C # page that when the page first loads, a bio is diplayed in that center section based upon sql executed from my code behind. I have 4 link buttons on the page that when clicked, fill that center section with other content based upon which link button they clicked (News, Publications, Contact Info, and Presentations). I was all done, then I thought about using an UpdatePanel to get rid of the annoying "flicker" when the page posts back on the click of the link button.
View 3 RepliesI 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.
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.

I am building for a class I am taking. I am familiar with Win forms, but I am not sure how to duplicate the same behavior in a Web Form. The 1st question I have is: I have a menu on my web form, but I am not sure how handle click events from the items on the menu.
View 3 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?

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.

the user can change the data within the gridview then click a save button to update the data within the database.

I have a GridView attached to an ObjectDataSource (returning a DataTable) in a UserControl. The code is really simple. Data comes down fine when the page is first rendered. When I click on Select or Delete (inside TemplateFields), RowCommand is supposed to fire but it doesn't, the page goes straight to Page_Load. I literally have 0 other event handlers that are set on this control and everything else in the codebehind shouldn't even fire if it's a postback. Also on postback, the Select and Delete buttons disappear. It looks like the TemplateFields are still there but they're empty. The data fields (all of two columns) post back fine.

I have a GridView in an update panel that is bound (in code-behind) to a business layer object. The first time this page is accessed, Editing, Deleting, Updating, etc. work fine.

I basically have an update panel being dynamically populated with a LinkButtons after a postback. This link buttons are being assigned an event. Now when I click the button the event is not firing. As I understand it the event is not firing because I'm not creating the button in the Page_Load event and therefore .Net does not remember this controls were created after postback. I'm not able to create these controls in the Page_Load as they are dependant on user input. So my question is how can I create these controls dynamically and have the page retain them and their events after postback?

View 3 RepliesWe have a page where you can insert a record. On the page we have validation to prevent duplicate IP addresses from being submitted for the same location. Now on the procedure side i have a condition that is checked, if you supply data that already exists for a location, then it will be updated. If its not then its inserted.. this all works fine.. issue now that i noticed is that we have a table that is part of the process, if you select say 3 from a drop down for number of emails, then when you submit the page, i have a loop for each of those emails and they are inserted into the email table as individual records.. works great also.. BUT here is my problem.. if i submit say an existing set of data and this time i provide say 1 email vs 3 from the previous time, i need to handle that in the procedure, so that the 3 are deleted and only 1 is now inserted and linked to that record..
Hope this makes sense..
Since im doing a foreach loop based on that dropdown selection, now when i look at my table im getting only 1 record in the email table... since the logic is within the procedure, when the page calls the procedure, it finds tha the record exists, deletes all the records, then only inserts the last record.
Example.
I submit the page with 3 emails today.. everything works and goes in as expected, there are 3 emails and record is created without issues..
Tomorrow someone else comes in from my team and decides to enter the same record data, thats not a problem, because there is an update statement if it already exists.. BUT this time they entered only 2 emails.. the 2 new emails are inserted / updated in the table, but the 3rd email is still in there.. its not removed.. so i tried to add a if exists condition to my procedure, but since the procedure is called in my foreach loop, the first loop sees the records, deletes them and inserts the first email, then on the 2nd foreach loop it deletes that last entry and inserts the next, so by the time it goes thru it has deleted everything it inserted and only captures the last record..
Just tried it now.. and since there was already 1 record in the table, i chose to add 4.. the end result should be 4, but i now have 5 records in there.. the first one and the 4 new ones..
