I have an intellisense problem in VS2008.I use code-behind, and though I can declare ASP elements in the aspx file, it's as if the code can't see them.The pages run OK,but when I type anAspLabel and then '.' for example, intellisense does not pop up the methods and members for this asp label.
I've tried the reset option in Options > Text Editor.Intellisense works fine if the class instance is declared in the code behind file,but it won't recognise web controls declared on the aspx page.
In my user control I have gridview, and this grid is created programmatically, using Itemplate. In InstantiateIn methods I have this code.
Select Case _templateType
Case ListItemType.Header
Dim linkButton As New LinkButton [code]....
I want to wired up Click event to this LinkButton, and use this event in code behind.This is constructor of GridViewTemplate how implements ITemplate
Public Sub New(ByVal type As ListItemType, ByVal colname As String, Optional ByVal infoType As String = "")
'Stores the template type.
_templateType = type
'Stores the column na [code]....
and i have this call from user control:bfield.ItemTemplate = New GridViewTemplate(ListItemType.Item, dt.Columns(col).ColumnName, "label")
where is Dim bfield As TemplateField = New TemplateField()

View 9 RepliesHow can I add a click event to my div from code behind?
Im looking upon clicking on the div to be greeted by a message box with would you like to delete this and a yes or no within the box?
All from the code behind:
while (reader.Read())
{
System.Web.UI.HtmlControls.HtmlGenericControl div = new System.Web.UI.HtmlControls.HtmlGenericControl("div");
div.Attributes["class"] = "test";
[Code]....
can you add a click event to it if so how?
I'm building a button in my code behind file and want to bind the click function to an existing click function of a different button. How do I handle this? I was hoping for something simple like:
Button b = new Button();
b.onClick = otherClickEvent();
but apparently that's not doable. Am I missing something here. I'm aware of OnClientClick, but that only deals with the JS side of things apparently.

View 5 RepliesHere is my situation. I have inherited an MVC 2 application. I am learning MVC 2 on the fly with this application. I am trying to validate a checkbox by doing this: Grey out the submit button until the user clicks on the "checkbox" then the submit button is enabled. 1st question: Where do I place the code to make this happen? 2nd Question: How do I go about doing what I explained? I wanted to use a simple javascript code within the click event of the checkbox but I don't see this in MVC 2.
View 4 RepliesI currently have this working but it requires me to have a static method as the method called in the code behind. I would like to be able to access some member variables that can't be static.
EDIT: Let me clarify, I'm looking to edit a value in one of the user controls on the page based on the button click. I am holding the user controls in a list on the page and using the parameters passed through the javascript to find the user control that I want to update and modify the value there.
It currently looks like this:
Javascript:
function incrementCompletes(obj)
{
var firstParameter = $(obj).parents('.parentClass1').find('.childClass1').html();
var secondParameter = $(obj).parents('.parentClass2').find('.childClass2').html();
[Code]....
I would like to find a solution that does not require the method called to be static.
Situation:
1) Click on 'Check' button and the button will disable
2) Run a processing code(for checking) and once it is done, navigate to a new page(NewPage2).
Here are 2 code situations (1):
[Code]....
and if I do this way (2),:
[Code]....
it will navigate to NewPage2.aspx, but during the execution of the processing code, ButtonCheck control will not be disabled as the Click Event has not finished, and I want it to disable during the checking process. If the 1st option is executed, it will throw to me "Response is not available in this context."? HttpContext is null for (1). In my opinion, I think that the navigation does not recognise the response object as it is in a thread and has exited out of the buttoncheck event. But I'm still not sure why.
how to disable the button and run processing code during the click event and be able to navigate to a new page?
On one page, I have 2 buttons. One that says Clock-in and the other says Clock-out. As of this moment, the application will allow you to click on the clock-in button without having clocked out the previous day and will allow you to click the clock-out without being clocked in. If a user is clocked in and they click the clock-in button again, I would like an alert to pop-up that would say "you must clock out before you can clock in". And if the user clicks clock-out without being clocked in, it should say "you must clock in before you can clock out". I am using VB in the code behind and SQL Server 2005. My current button click events are below:

I have a website that contains several aspx pages linked to a single aspx.vb code behind file. Four of these aspx pages have a single button on each (four total). My issue is handling each button's click event on each page using the single code behind file.
My four buttons' names are:
[code]....
On button click i do action A1, like
btnAction1_Click(object sender, ImageClickEventArgs e) {
//Action 1 code
}
now ,i'll click this button. If page is refreshed after Action1 is done..request is sent again and same action is repeated.
I've found posts about making a click event with jQuery for a button, however I need a little more then that. When any postback occurs on a page, I need to fire off a jQuery click event. Based on a condition, I want to continue processing (including running the server-side event code after the jQuery code), or, perform a redirect. I'm not quite sure how to go about this.

I need to collect the data entered by user for a quote and send all the data with labels to an email address. SMTP server is set up in web.config file, but I need to know the code behind for the submit button click event for the form. I do not need to store any data in a data base just need to send each label,field,radiobutton,etc. user responses to email address.

When does the variable "v" gets created every time for the 2nd scenario? Is the 2st scenario is equivalent to the 3rd one?
Here is my requirement -
1. I need to load a user control on link click event of a link button during postback of aspx page.
2. On button click event of a save button on that aspx page, I need to read the selected values from that user control on further postback.
If I write the loadcontrol code in link_click event, the control is not recognized at all in the button_click event. When I shift it to page_init and execute only during not postback, the user control loads with default values.
I have a project that has 4 pages and from each page have several link buttons to go each of the other pages. I would like to declare these url in the web.config file and give them a name and access from vb.net code behind.

View 1 RepliesI'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...
