This 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(...);
[code]...
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.

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 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:
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.
I 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
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.
how to catch update panel's request start (before partial updation request is sent to server) and response receive (before update panel is updated) events.
I've googled a bit for the exact order of all gridview events relative to and where inbetween page events. The only Microsoft article: [URL] is not very clear. I'm especially interested in the gridview row_command event relative to page events.
I would like to create a webpage which can handle user events like page navigation and page close. And also I would like to handle the event on server-side coding.
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?
do I handle a session timeout when using a update panel ?When the user session has timed-out and I click a button I get this error Sys.WebForms.PageRequestManagerParserErrorException - The message received from the server could not be parsed.I have tried to set EnabledEventValidation to false on the page but that didnt work, I have also tried to override the preInit on the page...didnt work either.
We 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..
for my dynamic user control, i am trying to do any event from that control (delete, update .... etc) but it disappeard when i make any event! this the code in the page to load it dynamically:
I'm trying to create multiple update panels to add to an accordion pane with timers with a _tick event to update the respective update panel on the page_load event.
I'm trying to use the DetailsView to make Updates. The problem is that it can't handle empty fields even though the underlying table field allows nulls.
I get a message like this if I change the "State" field to blank when doing an update
The parameterized query '(@Cust_ID int,@Cust_DL nvarchar(7),@DL_State nvarchar(2),@Last_N' expects the parameter '@State', which was not supplied.I'm using an object data source control which is calling the EditCustomer method in my Customer Class. I'm not sure how to fix this.
