Web Forms :: Binding A Click Events Validation To Whether Another Click Event Has Happened?
Jan 7, 2011
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...
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.
why the .Text properties are not being set in the code below? I've debugged this and the click event is firing and goes through that bit of code but nothing is displayed on the page.
I have a page with formview, the page contains a lot of input fields and a lot of validators and when I press "Save" button (in which I perform insert procedure) the form is validated, but button click event and page load happens. Validators and button belong to the same validation group. How to avoid button click and page load events happening when some validators aren't correct? In page without formview everything works ok, I click "Save" button and when all validators are correct only then happens button click event. How to fix that with form view?
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'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.
Okay after some further investigation it seems that this does work as expected when i run it in a standalone page, however we are using this script, and it appears that it is causing a conflict..
That script moves any href='javascript:... into the click handler, im guessing that the order the handlers are assigned may have something to do with it...
I have two asp.net buttons in my page.If i make button cause validation false then am able to fire button click event on server side but not able to validate text box values(but i need to validate text boxes) using required field validator.
In a multigrid i have validating two controls like date and amount.it is validating correctly when i press the tabevent.when i press the save button it is not validating.iam using two validations gruops and two validation summary.Then in save button i have also tried onclientclick() function with javascript it s working fine but if i give the correct value in date and amount records not saving how to over come this.
I have an ASP.NET 3.5 web application. There is a Master page with lots of client script and some simple server side controls. I have a user control that has a modal popup extender inside an update panel and some client script as well. When I add this user control on the Master page inside a new update panel whose update mode is set to conditional, and I add a link button whose click will initiate a method of this user control, the Master page's behaviour changes in a strange manner. All the buttons and link buttons start to fire their Click even on the second click. Nothing happens on the first click. As soon as I remove this user control from the Master page, everything seems to get back to normal and Click event fires on first click as it should. I hope I have clearly mentioned the problem here. I have already spent quite a long time trying to find out the reason for this but of no use.
I have a submit button which fires some code, the problem is I always have to click the button twice before it fires?
I have a number of dropdowns on my page, a number of other buttons all with unique id's, a postback is always caused on the page before the the submit button is clicked.
I am using one datalist control for uploading multiple images.I hv used one Asp:FileUplaod Control and one button in one itemtemplate.I am using reqired field validator and regular expression validator for file upload cntrl I am assigning validation group for both of them on ItemDataBound event of my datalist so that each upload cntrl hv same validaton group as required field and regular expression validator.Now what i want to do is - i want to show my error message in validation summary which is right at the top of the page.I want one know how to write javascript that will assign validation group of my control in datalist on which i click ?
I am having a problem where my button click event is still firing even though my custom server-side validation is set to args.IsValid = false. I am debugging through the code and the validation is definitely being fired before the button click, and args.IsValid is definitely being set to false once the custom validation takes place, but it always makes its way to the button click event afterwards.
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 am having 2 imagebuttons a gridview and a button. Now if i clicked on Image button i will show a grid. Now under button click i would like to capture which image button was clicked if 1st image button is clicked i would like to some values and if 2nd one is clicked i would like to show another
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()
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.
if i click a date in the calender control events under the clicked date should be populated in the gridview( not for a particular date for all dates in the calender ) in .net
How i can get gridpanel paging toolbar Firstpage,previous page,Next page,Last Page buttons onclick events in asp.net. Because i want to bind the data after the event.
I am developing a web application in Visual Studio 2008 using ASP.NET with VB. I am using a ComboBox control from the AJAX Control ToolKit. The ComboBox gets populated from a database.On Page Load the focus is on the ComboBox control. The user can use the Down Arrow Key to drop the listed items, move up and down through it and on pressing Enter key on the highlighted item the other controls on the page (such as Text Box, DropDown List) get populated with data related with the selected item from the ComboBox on which the Enter key was pressed.What I want is that if somebody uses mouse on the ComboBox items and clicks any one item the data related to the clicked item should populate the other controls. This should also work on Lost Focus.So how do we write the Mouse Click and Lost Focus events for a ComboBox control from the AJAX Control TookKit.
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:
