On my page, the user is basically registering for a site and I am trying to do a username availability check, without doing the javascript myself(not very good with it yet). The code that is shown below shows the contents for 1 out of 5 textboxes on the page. They all are in the same validator group that is triggered by a button. I have tested the availability query check itself and it works, but only once the submit button is clicked. Nothign is happening when I tab away from the textbox after enetering text.And this page is actually 3 tabs (not sure if there is some sort of a bug that involves tab containers possibly).
I here's the client-sdie code for the page (at least what pertains to this):
In text box onchange i call the javascript function
for calculating txt5 value
i.e.
in javascript method,
txt5.value = parseFloat(txt1.value) + parseFloat(txt2.value) + parseFloat(txt3.value) + parseFloat(txt4.value); and text box txt5 enabled=false,autopostback is true
protected void txt5_TextChanged(object sender, EventArgs e) { // here based on txt5 value i getting records from database and doing some calculation and display those value in txt6,txt7 }
The problem is the textbox txt5 can;t post back when text change from JavaScript function.
How can I do postback when text box value bind from JavaScript function and enabled=false.
I am creating a html table dynamically with some content and along with that want to add asp.net textbox control under one of its row. I am adding the control as
I want to call the OnTextChanged event of a static control added on aspx page.But the textbox is not getting displayed.Similarly I want to add a asp.net button also but it is also not visible.
I've the following problem: asp.net TextBox server side control, fire onTextChanged only when it loose focus. I would like to fire my server side event each time user press a key. How can i do ?
page here in asp.net3.5 with C# i m using a datagrid and have Control textbox in it and now oi want to use the textchanged event of this text box so i can perform opertaion on every text box
I have two textboxes which are start and end date fields. I want to change the calendar control that I display to jQuery UI's datepicker. Problem is when I select a date from the datapicker, OnTextChanged event or validations do not fire as it does when I type values in the textboxes or select it from a calendar control and tab out. CausesValidation attribute supposed to help out but didn't. I can just keep the calendar control.
I have textboxes being generated by a repeater that use OnTextChanged with autopostback enabled so that I can know when when the values change. This all works perfect.The problem starts when I try to click on any buttons on the page. The loss of focus triggers the event for the OnTextChanged; however, the event for my buttons never get fired. I checked this in the debugger and while debugging if I put a break-point in the page_load it will call both; however, without the break-point it still only calls the OnTextChanged event.I found this post on JavaScript. If my problem is also JavaScript related, why does the clicking of the button fire in debug mode?
I am having a big problem with the OnTextChanged event of a textbox....
I have tried several different scenerios and just don't seem to be getting it to work right...
I either get a full page postback which is not what I want or get a very peculiar extra textbox added to my page after OnTextChanged is executed...
currently the update panel is working as expected but it inserts an extra textbox into my form "magically"... so strange...the textbox that is added keeps a running history of what is submitted...you can take a look here at the behavior.. it is the email form in the middle of the page
Sample
Here is what I am working with...
[Code]....
and then in the code behind I insert a image to let the user know what is going on..
[Code]....
not sure why an extra textbox is added but everything else seems ok.....
I have a textbox in my app in which I have code behind in the "onTextChanged" event that I'd like to execute without doing an entire page post back .
I can't use use AJAX not an option for me (corporate thing).
Anyways, I have been struggling with the specifics on implementing ICallbackEventHandler. Or is than another way I can/should do this.The code in the textChanged event pulls a dataset from the DB and does a validation.
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 have a login.ascx control with three controls (LoginName, Password and btnLogin) , I want to rase a click event on this button from .aspx page because some restriction is there so that I am unable to write any code on .ascx page.I am bale to put loginName and password on .ascx by using query string but unale to raise event.
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 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):
[Code]....
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 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.
I 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?
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 have been tasked with designing a scheduling system to fit into an existing application. At present I have a SQL Table - Tasks which have a StartDate and EndDate column.
I have a requirement to set the Task as a recurring task i.e. Replace server backup tapes every day, or, Order more stationary once a month.
I am lost on how to design this. I can't seem to find a proper example on the net. can someone point me in the right direction.
I have an gridview with 3 columns. As default I entered for each columnns an headertext, but depending on an language parameter in the data the headertext is changed on page_load with a SetLabels function.
Recently I added an templatefield textbox with an autopostback=true and an ontextchanged event :
When a user changes the text in the textbox all events are executed properly BUT my headertext is set back to the default value (from the .ascx) even tho page_load event is executing properly WITH the SETLABELS function.
I have a formview with some templates. This is hooked up using objectdatasource. To the default layout I add some additional Label/Textboxes dynamically based on metadata in a database. I create the additional controls in the ItemCreated event using ParseControl on a Placeholder and populate the values in the DataBound event. This all works fine.
I have been modifying the extra textboxes using a ForEach loop in the ItemUpdated and ItemInserted events of the main formview. However this modifies each textbox regardless of whether the textbox has changed. What I want is to only modify the textbox if it has changed. I have tried to hook up OnTextChanged for the additional textboxes (using ParseControl) but the handler is never getting called. I thought maybe I was making a mistake in the execution order of the page but now I'm wondering whether ParseControl isn't hooking up the event handler correctly? Anyone come across this?
