Re: Pass textbox value to javascript function - ASP.NET Discussion Boards

I have a web app with some restricted aspx pages and my security check is being done by the master page of the aspx pages. (not sure if this is a great idea).

my problem is if there is no logged in user or he does have the required rights, i forward to a No-Rights error page.

I want to specify this page relative from web-app root. This is important to have portable code (locally pages are at localhost/Project-Name/Restricted/etc..., while on server they are at host/Restricted/etc...)

Someone suggested the ~ option, but this does not work in code behind - it only works in aspx pages. My security checks, of course, are done in the code behind.

any help?

I think role based security is what you are looking?

For the full path use Page.ResolveUrl(), for a relative path (relative to the user's browser) use Page.ResolveClientUrl. Both will take in the ~ format and map it to a real path. If you are in a control, the methods are available from Control as well (Page is a type of Control).

Passing the textbox is easy - you use document.getElementById to get a reference. The ClientID property on the server side will give you the param you need for that. If you want to 'show messages', your best bet is to make controls visible in the same js, or show a confirm or alert message in your js

there is some way to get the text box value Wink | ;)

one is to use .ClientId in your asp code like this :
document.getElementById(<% textbox1.ClientId %>).value
or if did`nt help you can do something else Smile | :)

the ClientIds always the same as each other , so you can find the ID by view source of the page ! Laugh | :laugh:

for example it will be like this :

document.getElemetById('ctl00_ContentPlaceHolder1_textBox1').value

Can you ping the machine that has iis in the machine that you cant access your application ?

Check if the IIS web site is running or not. Restart the IIS web site if possible.

Also check if network is available between you and server.

Yes. . Agreed. This is the primary requirement. Need to exempt the http ports from the firewall to reach the server.
Its the most basic requirement, Indeed. Rose | [Rose]

There are multiple option :
1. You can use Page and Restrict the page limit to 1
2. On RowdataBound, restrict the limit.

Opening new page with window.open() and passing query strings to it [modified]

Chesnokov Yuriy12-Aug-09 22:55

There is a nice controll attribute to add e.g.:

this.buttonAdd.Attributes.Add("onclick", "window.open ('SomePage.aspx','Add','scrollbars=1,resizable=0,width=730,height=580')");

say added during Page_Load.

Can I perform such window.open() by clicking on the button without postback? and opening desired page like SomePage.aspx?param=value

Well just make it

this.buttonAdd.Attributes.Add("onclick", "javascript:window.open ('SomePage.aspx','Add','scrollbars=1,resizable=0,width=730,height=580');return false;");

return false means the page will not be posted back.

No, the code provided already does not present postback after the button is clicked.

What I need is to click the buttonAdd and to open SomePage.aspx in a new window with params passed to SomePage.aspx as a query string.

After the click on the buttonAdd happen, the page with buttonAdd should not post back.

yes. The code I provided just does that.

Check if you have correctly applied the code or not.

Just see what I have done:
In designer I wrote :

<asp:Button ID="btnid" runat="server" />

On the server side I wrote :

btnid.Attributes.Add("onclick", "javascript: window.open('testform.aspx', 'download', 'left=1000,top=1000');return false;");

Thus whenever the button is clicked the new window will load the page, and it calls the server but the opener window doesnt post back.

If you want to check just place Response.Write("Testing Postback"); on the OnClick event of btnid. You will see the calling page doesnt write the string.

Hope you understand. Thumbs Up | :thumbsup:
