I am a quite new to web development and I am trying to do some small form updates without causing a postback. For example making a control visible when a drop down list is changed.
I have so far come across some features that achieve this like the RequiredFieldValidator inside an update panels. However, these are specific to a single task.
What are my options to achieve these client side updates in Visual Studio? At the moment I don't know any JavaScript, so I would prefer another solution if it exists.
I am using VS2008, SP1. I am unable to put breakpoints in my client side javascript code. Wherever I try to put the breakpoint, I am getting the message: "This is not a valid location to put the breakpoint". I have the js intellisense working fine. I also unchecked the two "Disable Debugging" checkboxes on IE. Due to this problem, I am unable to debug the js in VS 2008.
Ho Do i change a value of a label control using client side?
function Test() { document.getElementById('Labelj').innerHTML = 'Your new value'; }
The problem i am having is: I am trying to input the code, but when i type in the javascript, it is not recognising the "innerHTML" value. It is not being promted in my intellisense, therefore the function is not working..is their something i am missing?
Has anyone found a tutorial for reporting using VS2010?I would like to create local reports (RDLC) with sub reports or some other solution for master details, preferably with data coming from entity framework 4, but objects data source will do if that isn't possible.
in a form i have a buttoin, when click both OnclientClick and postback should happen. on clicking the "Email" button a client side "mailto" tag should do the work and pull a new message window on the client's machine.
whereas, the email addresses should be invoked by the post back. so , when clicking the button the server side post should happen and on return the client side script should be invokded with the values read during post back, and populate all the email addresses.
i need know how to first do a server hit take the values and then execute the client script with those values without using AJAX
If I have a standard HTML textbox: I can retrieve the value using Request.Form. But how do I go about populating this textbox from the server-side? I tried Request.Form["txtTest"] = "blah"; but got a readonly error.
can Visual Studio 2008 be All-In-One tool to integrate source code continuously from team members, build, unit test?
Having used Visual Studio Team Edition 2005, unit testing each method within VS itself. I strongly believe that it is feasible to add-on tools. Example ankhsvn tool to use SVN from Visual studio [URL]
In my investigating i have come across number of tools(shown below) to use with Visual Studio 2008 professional
Development tool:- Visual Studio 2008 professional using Subversion as source control tool. Continuous Integration:- Hudson or Cruise control Build tool:- NAnt Testing:- NUnit, Selinium As Visual Studio 2008 can be used for unit testing I think NUnit is out of consideration.
In the same way i would like to have any other tools/add-ons to Visual studio to implement continuous integration, building and unit testing. This process should be automated such a way source code between team members is continuously integrated, built and unit testing is done as configured.
Objective is to use few number of tools as add-on to Visual Studio or achieve most from Visual studio itself (example unit testing). Visual Studio should be all in one tool.
I am aware that Team Foundation Server best suits my requirement, but it is out of scope due to its cost.
I have a web app that needs to do two things at the same time. After a user clicks a button on the site, a javascript function needs to execute and while thats working I need the server side code for the button click to execute without waiting on the client side to finish.
To be more specific, the client side function takes about 23 seconds to complete, and while that is running the server side code promts the user for printing a document. So I need the javascript to run "in the background".
I know that I can receive an javascript object from the server via ASP.NET AJAX using Json. But I am not sure how can I send an javascript object from my client-side javascript to my server-side code. And if I can, how can I extract this object in my server-side code and access its members?
I have code on my server which works very well. It must crawl a few pages on remote sites to work properly. I know some users may want to abuse my site so instead of running the code which uses webclient and HttpRequest i would like it to run on client side so if it is abused the user may have his IP blacklisted instead of my server. How might i run this code client side? I am thinking silverlight may be a solution but i know nothing about it.
I have a user control which contains a CustomValidator which is used according to whether a RadioButton is checked or not (there are several RadioButtons, I'm only showing the relevant one)
There is some client + server side validation code (the server side code does exactly the same thing and is skipped for brevity)
<script type="text/javascript"> function ValidateDateFields_Client(source, args) [code]...
There are two instances of this control in the page. When running the client side version it hits the wrong one (the version of the control which is disabled). You can see from the generated HTML both are correctly specified. I'm not sure how .NET works out which clientside function to call given they both have the same name.
[code]... Do i need to add something in to scope it? What's the best way to achieve this? If I disable the loading of the second control everything works fine.
I have a question, I am writing a user tracking class that needs to obtain the screen resolution of the user. I have the javascript all written and it is working along with a hidden variable ( used to set the javascript vars so I can access them server side ). What I am running into is when I try to access the value of the hidden variable on Page load it's not there, but If I cause a post back I can get it. How can I access this data on page load? There is no guarantee that the user will ever cause a postback, some users just look at the home page and leave.
Is there any tool for Visual Studio 2008 which can reformat ASPX code to make it more presentable (eg insert line breaks, format the lines so they wrap when necessary, etc)?
I am having issues correctly setting up reference to javascript code to a custom validator.This is my javascript code in the .aspx page.
[Code]....
And here is where I add the Client Validation to the customer validator in the code behind. [Code]....
The validation is if there is a value present in the first text box then the second text box is required.The page throws an error when the validation should fail, but if I ignore the error the validation works correctly.Do I need to move my javascript to the code behind as well?
i am not sure if my design have flaw but would like to know what others have to say, i am in a situation where i am trying to acheive two things in one click.
using : asp.net web form
i have a web form with few textbox and a gridview control and a button.
if i click on the button i am executing two things
1) asynchronously get data from server to client (working great) and able to display the data in the textboxes.
2) same click i want to bind the gridview.
[Code]....
recap:
1) jquery script execute asynchronously to get data from server to client and display in the textboxes 2) server side code to bind the gridview.
PROBLEM:
if i have onClientClick="return LoadDataById(); then it executes ONLY ajax code and does not execute server side but if have onClientClick="LoadDataById(); then it executes client and server but textbox value wipeout. (the textbox value popuplate through ajax)
i appologise if thisis a silly question but i just want to be completely sure something is not possile before i tell this to my manager.
i am a WinForms programmer by trade, but i have put in charge of making a web site for our sales team, and web development is a new area for me. the web site is written in ASP.NET, C# code. it is finished, however they are complaining that there are too many page refreshes.
first of all, we have an SQL server with all our data in it. on the main web page, the user must select their country of interest from a DropDownList. when they do this, all our customers from that country are displayed in an html table, generated by a Repeater. i have set AutoPostBack on the country DropDownList to true, so each time the user selects a different country, the SelectedIndexChanged event handler is called, and in here i generate a new sql statement with the selected country, and re-bind the Repeater.
There are also a few other DropDownLists that do other 'filtering' stuff. for example, one DropDownList selects whether to display customers whose license expires soon (within a week), and another DropDownList filters the customers who currently have an open support case. All the DropDownLists have their AutoPostBack set to true, and in their SelectedIndexChanged event handler, i work out the sql based on the values of the DropDownLists, and re-bind the Repeater.
the problem with the above is that each time the user selects a different value from the DropDownList, the page refreshes, clearly because the AutoPostBack is set to true for them all. so to stop this i need to set AutoPostBack to false - but then of course the SelectedIndexChanged event handlers are not called, and so i have no place to rebind the repeater with my new sql statement.
so what i really need, is to be able to set a DropDownList's AutoPostBack to false, and handle the rebinding of the Repeater in some client-side event, which does NOT result in a postback. the Repeater will be bound by some sql, which is generated by the values in the DropDownLists (eg "SELECT * FROM custTable WHERE [Country]='" + CountryDropDownList.Text + "'"), so in this client-side event i need to be able to reference the asp.net controls.
