I know to code to a specific event, you'll have to select the control and select the event in the event button with an image of a lightning bolt near the properties window, but I cant seem to find the event list for the web page..like the pre render, load..etc.

I was just wondering if someone could help me. I would like to have an event calendar system whereby I have an XML document containing a list of events, with <Title><Date><Description> and <URL> nodes. I have bound them to a data source.What I want now is to add a calendar to the page, so when a user selects a particular month a list of all the events in that particular month are listed in date order.
View 1 Replies1) I know there are lots of web sites that describe in what order events are called during the Asp.Net page life-cycle. But is there also a tool, perhaps Reflector, that would enable me to figure out by myself in what order are ALL the page's events and their event handlers called during the page's life cycle? 2) Would you say that trying to figure out exactly what is going on under the hood is a good idea or a waste of time? To clarify - I'd like to figure out exactly what is going on when a control tree is build - thus all the method calls, all the events called etc needed for control tree to be build ( I imagine there are hundreds or perhaps thousands lines of code written just for building a control tree).
View 4 RepliesI do not know how this has started but when creating new pages in a web project using vb.net coding, when I add any control such as a button or something else and then do to the vb code page for it, I click the dropdown on the left and it does not show the controls. What would cause this? I am using a master page with the page and the controls are going into the content sections. If I add a line like:
Code:
[code]....
then I have events. But in another peoject I do not have to do this. Is there a reason why? Maybe a setting that was changed? I'm using VS2008 in vb.net language.
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.
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.
View 4 RepliesAre there any other events besides the OnTextChanged event? Like is there a key up event of some sort?
What I'm trying to accomplish is when a user fills in this text box it automatically fills in a couple other text boxes.
I was wondering specifically about whether ItemCreated or ItemBound happens first but I can't seem to find any information on the order that ListView events fire. Can anyone point me to a resource for this information?

I am trying to fire one event out of two avalible events based on a check box selectoin, I have already registered the two events in the page_load() and i check if the check box is checked (checkbox is located within a gridview) then i un-register one of the events and just keep one events registered as following(Only relative part is shown):

I am trying to fire one event only based on the checkbox selection. I tryed to debug and noticed that, in fact, both evetns always get fired starting first with Button_SessionStartOrEnd_StartSessino and then Button_SessionStartOrEnd_EndSessino. So how can i fire one event only? please note that my code to check if the ckeckbox is checked within the girdview works fine.
I'm trying to create a page that displays a databound gridview to the user showing them the items being processed. Then the page should immediately begin processing. The problem is that the page never shows the gridview (or any other control) until the process is complete. The process is being sent to a WCF service. I've tried setting the page to async and running the wcf in async mode but the content still fails to display.
View 1 RepliesUsing C#, ASP.NET 3.5, VS 2008.
On a page with some user controls, I need to execute some lines of code only once (i.e. not on postback), however, the code must run after ALL page objects complete loading.
Example, Page1.aspx also contains uc1.ascx and uc2.ascx. If I imbed the code in a if (!PostBack) code block, it will end up running before the corresponding page load is completed for uc1 and uc2.
Is there a way to run the code on Page1.aspx once AFTER all the objects on the page have run thru their page load events?

View 2 RepliesI finally figured it out. It's quite a lot of code, so check out the zip!!I have a control, with multiple controls, which contain multiple checkboxes. ee pictureWhen pressing "Submit" I'd like, if any checkboxes have changed, to fire an event containing two Lists - one containing the checkboxes which check-mark were removed and one containing the checkboxes that's been checked.Hooking up on the CheckedChanged-event is no problem and currently I just add the checkboxes to the added/removed lists in their container, but when can I fire the event in the container with the populated lists?
View 1 RepliesI would like to find a way of running custom validation on a checkbox list. The reason why is because they were a radiobutton list. Then our client decided they wanted to be able to uncheck them (without a clear button) so in the end I had to change them to checkbox lists and make them mutually exclusive. On some of them, one must be selected and I downloaded this: [URL] to set them as required - worked nicely. Perhaps there's a way of building on this further to create some sort of custom checkbox validation. why I need this custom validation is because when the built form checkbox list = flat or maisonette then floor level is then required.

Since i have 5 buttons that pretty much run the same code, except for the database updates, i found some examples of how to do this.. so i created 1 button event, and put my general calc code then some if statements to determine what button was clicked.. but doing this now i get a NullReferenceException
and here is the code its complaining about, why would this work within the other button events, but not this one? Ive compared and and all the buttons on the page are the same with the except of the database entries.
Button b = (Button)sender;
Label tfive = (Label)FormView1.FindControl("five");
Label ttwo = (Label)FormView1.FindControl("two");

I've been searching a little bit to try and find the answer to this problem. As of right now another person I work with has designed a wizard step with an upload button in part of it. After the person clicks the browse button and selects their file a validation statement comes up saying, "Please click 'upload and continue' or clear the field" and then is supposed to disable the continue button until this is done. He started by adding a RegularExpressionValidator and found it did not solve his problem.
Now that he's out today we're working on trying to solve this and my first though is to actually use a custom validator instead and have it call a function in the back-code for validation which checks to see if the "Upload" click-event has happened. Is there an easy way of verifying whether or not a click-event has occurred. Basically my conditional is shown in the pseudo-code below...
