View 1 RepliesI'm evaluating two options of accessing a server side data on client side. Little bit confused about the efficiency or may be you can call it as finding best approach to do it.
I need to access a server side data may be an integer value in javascript on client side. I know about two options to do it.Create a public variable or property on server side and set it to javascript variable on client side as below:
var value = eval(<% =value %>);
Create a asp hidden variable and set value in this hidden variable from server side and access it through javascript using document.getElementById().
Which is the best approach and what are the pros and cons?
I am trying to set a hidden type value to x on Server Side and then access it with Javascript. I have tried multiple ways to accomplish this.
At the basic level this is what I am trying to do.
Aspx page
<asp:HiddenField ID="HidRowNumber" runat="server" />
CS Page
In IsPostBack
HidRowNumber.Value = EFileRowNumber.Text;
Javscript
var status = document.getElementById("<%= HidRowNumber.ClientID %>").value;
When I am debugin it say it HidRowNumber's Value has changed to x but when I access the value with JS it always returns ''.
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?
View 1 RepliesI have a datalist on my page that allows a user to build up with orders. Each time an order is added I post back to the server, updated a dataset and then bind the dataset to the datalist.
I would rather do this on the client, for performance reasons.
Does anyone know of a way I can add a row to a datalist via javascript/jquery?
I understand this may not be possible using a datalist, so any other type of client side list tool.

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.
If I have a standard HTML textbox

I want to ask how to get the value of var title :
From this code :
protected void btnSubmit_Click(object sender, EventArgs e)
{
string script = "var title = $('.rsApt').attr('title');";
ClientScript.RegisterStartupScript(GetType(),"popup", script, true);
}
All I want to do is insert a hidden column into an asp:Griview that I'll be able to access through javascript.
View 3 RepliesIn ASP.Net, I want to give a user an ability to save the text entered in the textbox to the client machine. So that, user can copy paste it for later use.
Is there a way to show, save as dialog so that user can save the text in a text file on client machine? or, if there is any other alternative?
According to MSDN and the MCTS self-paced training, asp.net can use Hidden fields for client-side state management. The book material goes on to say view-state is more secure than hidden fields because the data is encrypted. I must be missing something here. I setup a Label and made it hidden. I can store data in this hidden label and it won't even be sent to the client browser. This not only works like server side state (note the runat=server), but this seems more secure than view-state because there's no need for encryption as the client can't even see the field.
<asp:Label ID="Label1" Visible="false" runat="server">secret info</asp:Label>
<input id="Text2" type="text" style="visibility:hidden;" value="secret 99" />
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?
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.
View 2 RepliesI have a content-sensitive firewall between my clients and my server. If we exclude SSL solution (it's not available in my case) then I was thinking of a javascript library which encrypts custom fields at client-side and a .NET class decrypts them at server-side. Is there any solution out of the box (maybe a server control) ?
View 2 RepliesASP.NET newbie question - fastest fingers!
I have a page that needs to pull some script off the server, including tag info, for the page. Thus:
<html><body>
blahblahblah
<%: Model.TaggedField %>
</body></html>
Problem is, the value of Model.TaggedField may include HTML tags, but the page automatically converts the tag info to <myTag> etc.
What method can I call to make the value of Model.TaggedField be transmitted verbatim to the page?

How can I get such a value to be propgated over to the server?
View 3 RepliesI have an existing GridView which contains the field "partner name". It is sortable by partner name.Now I need to change the Partner Name field and in some condition make it clickable and alert() something.

<asp:BoundField DataField="PartnerName" HeaderText="Name" SortExpression="PartnerName"/> [code]...
enable me to access "lnk" by id and add to its attributes. However, I lose the Sort ability.
I'm new to ASP.net 3.5 and testing functionality before developing an asp.net web site. I created a page with a formview. I added several text boxes. I created an event on the FirstName_TextChanged event and added a stop in the sub. When I open the page in the browser and type in some text in the FirstName and press tab, nothing seems to fire.
1) Is this supposed to fire on the client side when text is changed?
2) If so, would the vb.net code entered work like Javascript code on the server?
3) If so again, is it possible to update another textbox based on the text entered into the FirstName on the Client Side (would do this in Javascript in Classic ASP)?
I think I'm totally confused. I've been searching web for article about how to do this.
Is there a matching client side event that is fired before or after OnPageIndexChanging is raised? Such as the OnClientClick, I would like to append a script when the paging numbers / arrows are clicked. Is it possible, of so; how?

I am using VS2010, .Net 4. I am trying to add a ScriptManager to my page, so I can reference an AJAX Enabled WCF Service. When I add the ScriptManager control to my page and view it - I get the error shown below. I have no clue how to resolve it. I get the error by simply putting the control on my page (not reference the WCF Service).
Error seen when "viewing source":
(script src="/ScriptResource.axd?d=cN6E-bUIIAhb0PYSsbqev2ndhi3W3ltVtHjrJ-T5yBfO3jQBEHWjU39PLAybm-JIxwU4s59EhJFweLHmABl1zA2yo8fKhHYHGS7RTy1fhECuWqXbMMy5aCuSlqHbfp3advQcwp11SqaDwkvU1YN6Bw2&t=ffffffffbd2983fc" type="text/javascript")(/script)
(script type="text/javascript")
//(![CDATA[
if (typeof(Sys) === 'undefined') throw new Error('ASP.NET Ajax client-side framework failed to load.');
//]])
(/script)
Actually, my problem is that I am not able to access the service. I am referencing it inside the ScriptManager and have the javascript code in place, but Firefox is reporting that it cannot find it. Says it is not defined. I do not know how to test this or determine where it is failing.
