Web Forms :: EnableClientScript - Only Clientside If True Or Both Client And Server?
Nov 18, 2010
subject says it all...... when using the various validation controls like requiredFieldValidator, and EnableClientScript is true (the default), does that mean that the only validation is done client side? or does it mean that it is done client side in addition to server side?
I know if the only validation is done client side, like with javascript, it can easily be circumvented. I want to make sure my validation is done serverside, so do I need to set EnableClientScript to false?
I have a treeview with EnableClientScript=true. It is not in an update panel. It works fine on my local machine but when I place on server, I get a WebResource.axd error when I try to expand the treeview. If I set EnableClientScript=false, it works fine. I need to have it set to true. Is this a bug?
I have recently found this snippet of code but I am unable to get it to work. Does anybody know if the $index syntax has changed in the latest version of the client templates?

time for some expertise. I have a datalist which contains a radiobutton in the itemtemplate. This radiobutton is disabled (set enabled to false) by default. On the html output I have a checkbox, which, when ticked, enables the radiobuttons through javascript. This is all working fine. The rb's are enabled and I can check them. However when the page is posted back. The checked property is always false.
I use the code below to retrieve the value of this rb:

This code is working fine when the initial state of the radiobuttons set to enabled server side.
It took me a little while to figure this out, but the AllowPaging="true" on the FormView seems to be the culprit. I don't have much experience paging from a FormView, but for this requirement the customers wants this kind of UI.I have a FormView with DefaultMode="Edit", which is bound to an EntityDataSource. One of the entity's properties, "ExternalID", determines whether some of the other properties in the entity are read-only. For example, if IsExternal==null, the FirstName, LastName, and Email fields should be rendered as TextBoxes. If IsExternal!=null, the 3 properties should be rendered in Label controls.
Anyway, if for example I have a textbox that I want to enable when the user check the desired checkbox/radiobutton, I like the textbox to be default enabled=false. What's the good approach between these two?
I need to know on the serverside, if a RadioButton has been disabled (by javascript) on the clientside.
The (serverside) Enabled property is not the same as the (clientside) disabled property. Using MyRadioButton.Attributes("disabled") doesn't do the trick either.
I'm curious, anyone know the mechanism a checkbox control uses to remember that its checked or not checked after a postback?If I add them manually to a page via html as in <input type="checkbox"/> I have to use javascript and hiddenfields to keep things checked after a postback and I would have to have an onclick="dosomething()" inside the tags.Viewing the html source code for a page with a .NET checkbox control, there is nothing like that there.
I was writing a custom control and rendered my own checkboxes when I came across this problem. After the postback, the control would reload the checkboxes from viewstate and forget the user had clicked anything. As I couldn't use hiddenfields to track the changes (they got reset from viewstate too), I ended up using .NET checkboxes as childcontrols instead but this experience got me thinking.
if in the code behind, I set the label to "You must enter a value if the textbox is empty" to validate it on the server side and this is fine, but if javascript is enabled, I don't want to show the client side validation and the server side label together. Is this something where I would just have to disable the client-side validators if javascript was enabled?
i have a complete form in my database as row for example name of the field ,is mandatory, sortid, regularexpression, datatype, maxlength , default value etc. So the form is completely dynamic.now i want to perform the client side validation on the form . What will be the best practice for doing that? like i have to see that if the field is mandatory check it for null and if not then leave it on the client side . i am thinking about setting hidden field for it .
I have a required validator that I check a textbox clientside, but then on post I check the database for values that have been used. I want to show the error in the RequiredFieldValidator when it post back. How do I do this?
I have to create a HtmlInputText control in code and while in code set it so that it will respond to text changes purely on the client side and not generate a server side event. In an aspx page this would be done like so:
Why am I getting this error? I'm trying to do a calculation on my GridView2 and I'm using clientside javascript. I need to add the onkeyup attribute. How do I do this?
Code Behind:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load CType(GridView2.FindControl("TextBox13"), TextBox).Attributes.Add("onkeyup", "calculateSubTotal") End Sub
We've got a client app which connects using TCP to a server. Additionally, the client app makes use of .NET remoting to talk to another piece of locally running code.
I'm tasked with creating a "Client Simulator" to do some testing, where we'd need to have 100's of clients connected simultaneously to the server. Ideally, this would work out great if I were to run each client in it's own space, such as a VM, but this is not logistically feasible.
how to handle this? Is there a tool that could do something like this? Or some sort-of .NET concept I could use?
I'm making a website in ASP.NET 4.0 where I make use of the RequiredFieldValidator control to validate a wizardstep.It works perfectly with Javascript enabled, but when I turn it off (in my Firefox) it just goes to the next step.We don't do a Page.IsValid check, but we don't do much on the "next button clicked" event either.Certainly not something that is forcing it to go to the next step.
I presume only the Button server control in ASP.NET has AUTO POST BACK set to TRUE by default. All others need explicit setting of this property on need basis.
My PasswordRecovery Control is not working. It is giving me SMTP problem. I set my proper gmail address with port number, valid user name and password. But not working? Do I require to set more settings?
The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.7.0 Must issue a STARTTLS command first. pg3sm5232120pbc.2
Here is part of my code. The commented portion is the logic in which i am trying to implement. I want client side validation to be done and checked to see if it is correct format (MM/DD/YYYY).
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.
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'm going to create my own project, and i have some difficulties with technology selection. I will have client application(windows forms) and web service. Data exchange between clients will be only by using this web service. Data will be like image stream,so I don't know which technology to use. I started to look at WCF, but i don't know a lot about it.
