Java script in asp.net

I have two questions to ask in this forum
1) How to include java script file in .aspx file?
2) I wrote a following class with a function called JavaScriptFunction. The issue I am facing is when I am using this function to display message, the background of web page was white ie no style sheets were applied to .aspx page and no others controls were displayed. When I click on “ok”, I am coming back to same page.

The code for the JavaScriptFunction is as follows
public static void JavaScriptFunction(string alertmessage)
{

System.Web.HttpContext.Current.Response.Write("");
System.Web.HttpContext.Current.Response.Write("alert('" + alertmessage + "')");
System.Web.HttpContext.Current.Response.Write("");
}
.
Thanks in advance

1) How to include.....

<script src="path.js" type="text/javascript"></script>

2) I wrote a following

Instead of response.Write ,try this
Page.RegisterStartupScript("p", "<script>alert('" + alertmessage + "');</script>");

Best Regard

The way I understand about your problem is that you want to show a page with or without stylesheet dynamically by clicking a button.

In ASP.NET 1.1, you should handle this functionality in base page. There should be one property that allow users to change the path of CSS. In my project, we allows users to change the themes dynamically. Since there is no build-in theme system in ASP.NET 1.1, we handled it in base page.

In ASP.NET 2.0, you can have more than one theme. So, you can change one plain theme to another theme dynamically by changing themeId or Skin ID.

Hi..
Could any one tell me how to add a variable value(or property value) from codebehind to a function in a javascript file?

I am too late but i will never give up

Michael Sync19-Aug-07 23:05

19-Aug-07 23:05

Something like that?

button.Attribute.Add("onclick","func('val');");

Sorry I didn't mean as a parameter for a function.I mean something like the following:

<br />
function donow()<br />
{<br />
var b=ss;//where ss value is set from code behind<br />
}<br />

And the script file isn't running by clicking a button.it is an ordinal script block in a javascript file.

I am too late but i will never give up

I don't think it can be done directly.

But you can use server-side hidden field to commute between client-side and server-side.

<input id="Hidden1" type="hidden" runat="server"/>

In Form_load

<br />
protected void Page_Load(object sender, EventArgs e)<br />
    {<br />
        Hidden1.Value = "13";<br />
    }

You can set like that..

In Client-side ~

<script language="javascript" type="text/javascript"><br />
      function getvalue(){<br />
        var var1 = document.getElementById('Hidden1').value;<br />
        //do something.<br />
      }<br />
    </script><br />

So, Even thought you can't set like that "var b=ss;" directly. but you can set "hidden.value = ss;" and then, var b = hidden.value;

Hope it helps.

disabling an item in combobox

I did as you told me and it works.

But I think if it is possible to set the variable in code behind using
ClientScript.RegisterClientScriptBlock it will be more secure.Because I brought the value of the variable from database.So in the codebehind it will be something as the following:

<br />
 ClientScript.RegisterClientScriptBlock(this.GetType(),"MyScript",<br />
            "<script language='javascript' src='functions.js'>function getvalue(){var var1 ="+ss+<br />
";}</script>");<br />

But it didn't work with me...Any way if I couldn't find any more secure solution I will continue using your solution which will solve my problem too.

Thank you very much for helping me all the time. Smile | :)

Hi,

You can encrypt the password easily by using SHA or MD5 algorithms. And save encrypted pwd after generating. And also there are cryptography classes are there to encrypt the password.

How to Bind the Data to DropDownListBox In GridViewControl

19-Aug-07 20:57

You have two option here.
1. Take one field in database,set flag 0 for deleted record.
2. create new Datatable dynamically and bind it with DataBase table and just remove rows from this table and rebind gridview with this table.
