I have a page and clicked on the button there it will open a new page containing some text boxes, user fill all the text boxes and clicked the button now first page open again and the question is : How can I get the vales of text boxes on the current page using both server-side and client-side
There is a restrictions to use of :
- Cross-paging
- Cookies
- Sessions
- Query strings
I've got two textboxes running server side and have their visibility turned off. I'm using a couple of ASP.NET controls which require the textboxes to exist. However, I am filling them from the code behind and would not like the user to see this. Can the user turn the visibility on and see the values entered in the text box? I tried using FireBug, and I couldn't seem to select the visibility option in order to edit it. However, I'm quite new to Firebug, so there may be another way? Or does running it server side mean that the client can't ever view the contents of the textbox?

I have null in my variable ...

TextBox1.Text = values
End Sub
I have a requirement of adding server side variables in client side and other way round. Because I need to set a value from client side using javascript and access the same in code behind page.
I have to use C#.Net and JavaScript.

Can we access the AJAX Combobox selected text,selected value & selected index from client side.I have searched all on the net,i cant find any solution.Is it possible to access the value from the client side or not?
View 3 RepliesSuppose I'm building a StackOverflow clone using webforms ASP.NET and jQuery. The Question page has a question, several answers, and comments under each. Requirements:Users can post new answers and comments, and edit existing ones, without postbacks. No UpdatePanels; the AJAX calls retrieve just the JSON they need, not HTML fragments. The page loads with all existing answers and comments in place (no javascript needs to run to read the page).
What I'm trying to figure out is how to do this without having to maintain two sets of markup (one that's bound on the client using some form of jQuery templating, and one that's bound on the server using traditional WebForms).

I am having a page where I need to maintain around 70 to 80 hidden fields to store some values. These are required because I need these values for executing some code at the client side (validations, calculations, etc,.) in java script.
Wanted to know if there is a better way of storing these values in my page instead of using hidden controls because I guess using so many hidden controls is making my page very heavy.
Something like a hash table or list dictionay that I can access from both the server side code and clint side java script?
getting a particular datatable values from the server to the client using javascript.
Ex.In my class which is Countries.aspx.cs I have this somewhere on my code say on the page load.
DataTable dtbCountries = Repository.GetAllCountries;
my dtbCountries now contains this record
ID Country
1 HongKong
2 Japan
3 Korea
In my webform I want to get the values of my dtbCountries using javascript

What should I do? Or what's the best thing to do to expose my dtbCountries in the client.
I am putting together a module that will drop into a DotNetNuke portal and I'm populating a Telerik RadGrid with data. I have followed every tutorial and example I can find, but the result keeps coming back with "object Object", "null", or "undefined".
I need to:
1) get the value of the "BookingID'" column for each row that is selected
2) pass the value into a url string that opens up in a RadWindow.
I'm trying to do all of this using javascript, but if you know a better way, I'm down for anything at this point.
Here is my current JavaScript and a stripped down radGrid:

I am applying a field validator on a listbox which works when no item is selected in the textbox and some(most often the submit button) control is made to postback to the server.Now the problem is that if a person has entered the page and want to logout it still gives the same exception messages(which it should) rather than logging out of the page.I am using ASP.NET with c# as back-end.I want the the logout button(rather all except the submit button) to function prior to the validation
View 1 RepliesI want to be able to provide a list of files on an ASP.Net page which link to files on the users shared drives.
When the user clicks the link they can modify the file and then save it back to the shared drive.
An example would be:
<a href="file://M: estBook1.xls">M: estBook1.xls</a>
However this does not work, even from a trusted site.
I can understand the security implications but these can be managed.
I want to access all the files in a folder to add to a listbox and show to the user.
I know I can access a folder when it's a windows application. But in web application, is this possible? If yes, how?

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.
<script type="text/javascript">
//<![CDATA[
var ctl00_MCPH1_QueryTextValidator = document.all ? document.all["ctl00_MCPH1_QueryTextValidator"] : document.getElementById("ctl00_MCPH1_QueryTextValidator");

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.

The problem I am facing is that I got this code snippet from another source and I don't know what does the StoryID={0} means. I do know that the eval statement would sent the storyID of the selected file to StoryDisplay.aspx, I just don't know how to retrieve the values from the second page.
P.S. the second page contains a title label and an area(enclosed in <div> tags) for the selected text to be displayed.
I've been working on a task to add a validator to compare the values of two text fields in a ASP.NET 1.1 application.
It uses validators already, so the best approached seemed to involve a CustomValidator. I was inspired by the following example:
[URL]
I got the server side validation working - now I'm trying to add some client-side validation but I'm having a strange issue.
When I click in either of the two text fields, the value of the txtFinalGrade field is overridden to either "true" or "false". I've been having a tough time tracking down the code that's causing this. I tried using the IE Developer Toolbar to trace the script - as well as FireBug in Firefox (though this is an IE-only app) and I'm still trying to figure out what's causing this to happen.
Since I think this is a JavaScript issue, I'm posting that part of my code:

Anyone have ideas of things to try? Anyone have similar issues with textboxes being set to true/false when working with custom validators?

View 1 RepliesI am trying to add a client side event to a dropdownlist and I need to access the currently selected Text. I have tried:
ddl_tech.Attributes.Add("onclick", "document.getElementById('" + chk_techreview.ClientID + "').disabled = this.options[this.selectedIndex].text.Equals(' UNASSIGNED');");
and
ddl_tech.Attributes.Add("onclick", "document.getElementById('" + chk_techreview.ClientID + "').disabled = this.text.Equals(' UNASSIGNED');");
Both of which give me runtime errors when the event is fired.Whats the correct way to access this text property client side?I tried this but it does not enable the checkbox...
ddl_tech.Attributes.Add("onchange", "document.getElementById('" + chk_techreview.ClientID + "').disabled = this.options[this.selectedIndex].text == ' UNASSIGNED';");
ANSWER:
Well, along with having to use == rather than .Equals, when you set a checkbox.enabled = false on the server side it raps the checkbox in tags and sets it to disabled=true; therefore you must set BOTH the checkbox.disabled = false and checkbox.parentElement.disabled = false; on the client side to enable the checkbox!The solution:
ddl_tech.Attributes.Add("onchange", "document.getElementById('" + chk_techreview.ClientID + "').parentElement.disabled = (this.options[this.selectedIndex].text == 'UNASSIGNED'); document.getElementById('" + chk_techreview.ClientID + "').disabled = (this.options[this.selectedIndex].text == 'UNASSIGNED');");
