Disable Listbox's Click Event?
Mar 28, 2010
I have a listbox which acts as a list of items. If you click on some item, it's contents are shown in the panel on the right (few textboxes etc.). I need to have a validation on these controls as all of them are required fields. And I do have it. The problem is that, even when the validators are not valid, user can click the listbox and change active index (that doesn't have impact on the panel on the right, as SelectedIndexChanged isn't fired). The validators are standard RequiredFieldValidator with their Display property set to "Dynamic". So, what I want is to disallow the user clicking on the listbox and changing the index untill all validators are Valid. What would be your solution for that? Is that even possible?

I wanted to catch and handle the ListBox Double Click event and looked for some sort of mehtod to do this. In one of the articles i found the usage of;
Request("__EVENTARGUMENT")
-------------CODE----------------
If(Request("__EVENTARGUMENT") <>[code]....
I have implemented the code using this Request param and the code works fine. What i wanted was to understand how this works to accomplish the task.

the InitializeComponent method ive had to comment out as, im getting InitializeComponent does not exist in the current context and ive googled that its not needed for web forms?
EventHandler.Control.DoubleClick can only appear at += etc error ive tried Listbox.Controls.Add.DoubleClick but that gives ControlCollection.Add is a method which is not valid in the current given context

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?

Every time we click on a button. the Page_Load will fire first.
For my case, I have some controls added programmatically to the GridView, when the button click, the Page_Load event fire, my controls just go away.

I am creating a button dynamically in my code and attaching a click event to it. However I have to prevent people to click it while there is a process going on. So when it is clicked once, it should be disabled and when the process ends it should be enabled. How can I do that?

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 have a problem with disabling the tabcontainer.
The problem is that, if a user haven't selected anything, the whole tabcontainer must be disabled. If I disable the tabcontainer it in de codebind, the tabcontainer grayed out but the user can click the tabs.
I can disable one tab in javascript but how can I disable the whole tabcontainer?

I have a Gridview that has a button at the left hand side representing the row number. The Gridview has two textboxes and a dropdown listbox as templates. I would like to enable or disable the textboxes and the dropdown listbox if the row is not selected. I also need to enable or disable the templates depending on what the value is of one of the cells. When the templates are changed, I need to save the changes.
I have been able to get this working in the RowDataBound Sub but not in the RowCommand Sub when the row is selected. provide an example in VB.My current RowDataBoundSub, which does no work is below:
Protected Sub PropGrid_RowCommand(ByVal sender As Object, _
ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles PropGrid.RowCommand[code]....
My current RowDataBound Sub, which is working is below:
Protected Sub PropGrid_RowDataBound(ByVal sender As Object, _
ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles PropGrid.RowDataBound [code]....

I have a drop down that lists all our 40+ locations.. I then have a list box with all our locations as well. The client is presented with the question which locations have you worked at before. If they pick say 3 locations, i need to remove or disable those 3 from the drop down. I have other code for creating a drop down, but not sure where to go with this.
Here is my code for the controls and code behind:

I am trying to apply the same logic I applied to a FormView. Here is what I do: I have a DropDownListBox as one of my FormView fields and when I choose a specific option the fields inside my FormView are enabled/disabled according to the options chosen.
Well I havent been able to apply that concept to a GridView. Here is my code to the FormView:

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...

In my aspx I have this:
[Code]....
And this is what I trigger with jQuery:
[Code]....
The first time select an listboxitem, I got a message raised from alert('ok') but after that no more messages.
I found out that if I remove AutoPostBack="true" in the listbox, then this will fire everytime I select a listbox item => but then I can not get the event at the server to update some controls' contents.

Background: I am customizing an existing ASP .NET / C# application. It has it's own little "framework" and conventions for developers to follow when extending/customizing its functionality. I am currently extending some of it's administrative functionality, to which the framework provides a contract to enforce implementation of the GetAdministrationInterface() method, which returns System.Web.UI.Control. This method is called during the Page_Load() method of the page hosting the GUI interface.
Problem: I have three buttons in my GUI, each of which have been assigned an Event Handler. My administration GUI loads up perfectly fine, but clicking any of the buttons doesn't do what I expect them to do. However, when I click them a second time, the buttons work.
I placed breakpoints at the beginning of each event handler method and stepped through my code. On the first click, none of the event handlers were triggered. On the second click, they fired.
Example of Button Definition (within GetAdministrationInterface)

I added some food items in CHeckBoxList. I want to add selected food item(s) in a ListBox. The Text Property is name of the food and it's value is there Price (Food Price)Â As soon as I add any food item in a ListBox the total should be displayed.
Whichever code I wrote using it, if i select 1 item then it adds in a ListBox. But If I select another food item then Previous food item also added because it is selected. I will select some food items then it will be adding in the ListBox, I will check the total, if the total is greater than my budget then i can remove some food items.
