JavaScript function for custom server control

Hi All,
I am creating a custom server control for multiselection drop down list. This control contains AspxEditButton, check box list and panel. AspxEditButton and check box list are placed in that panel. I have to display selected items from check box list to AspxEditButton at the time of MouseOut from panel. Can I use code as follows at WebControl1.cs,

_panel.Attributes.Add("onmouseout", "Javascript:CtrlLeave(); ");

And can I write CtrlLeave() javascript function at WebControl1.cs How can I write a javascript function at WebControl1.cs?

Regards,

Anu

Just render the JS function along with the control. A better way would be to use embedded resources. I have explained it here[^]. Please take a look at that.

You can't. ASP.NET will have access only in the website area. It can't access files from some other drive.

nested master page problem

Hi, I am still a newbie in ASP.net development,

I try to learn about nested master page, and I got this problem

Cannot find ContentPlaceHolder 'ContentPlaceHolderUser' in the master page '/OnlinePrayer/MasterPage/AdminUser.master'

I have done some research in internet, but until now, I have not got the right solutions.

basically, in my website, there are 2 master page : AdminUser.master and User.master
and AdminUser is child of User,

In User.Master , I've got this following code

<%@ Master Language="C#" AutoEventWireup="true" CodeFile="User.master.cs" Inherits="MasterPage_User" %>
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <title>UserPage</title>
</head>
<body>
<form id="form1" runat="server">
    <div>
<asp:contentplaceholder id="ContentPlaceHolderUser" runat="server">
        </asp:contentplaceholder>
    </div>
    </form>
</body>
</html>

and in AdminUser.master, i've got this code

<%@ Master Language="C#" MasterPageFile="~/MasterPage/User.master" AutoEventWireup="true" CodeFile="AdminUser.master.cs" Inherits="MasterPage_AdminUser" %>

<asp:Content ID= "SubContent1" contentplaceholderid="ContentPlaceHolderUser" runat="server">
</asp:Content>

I thought that I had define ContentPlaceHolderUser in User.Master, but I dunno why I still got this error? in Admin.Master

I would be grateful if you could give me feedbacks about my problems,

thanks

Hi,I hope I understand your problem in a correct way.

Here iam giving you the code for two nested master pages and an aspx page which uses these master pages.

try it out.

1.User.master as follows.

<title>Title

Some content in main master page

<asp:contentplaceholder id="ContentPlaceHolder1" xmlns:asp="#unknown">
runat="server">
Child master page will be placed here...

2.AdminUser.Master as follows(child master page for User as you said and here the Master page file is User.Master).

<asp:content id="Content1" runat="server" xmlns:asp="#unknown">
ContentPlaceHolderID="ContentPlaceHolder1">

This is child master page

<asp:contentplaceholder id="ContentPlaceHolder1">
runat="server" EnableViewState="true">
Contents of pages...

Content in Child master page.

<asp:contentplaceholder id="ContentPlaceHolder2">
runat="server" EnableViewState="true">
Contents of pages.

3.Default.aspx page which uses the master page.(Master Page file is AdminUser.Master)

<asp:content id="Content1" xmlns:asp="#unknown">
ContentPlaceHolderID="ContentPlaceHolder1" runat="Server">

Some content on page

<asp:content id="Content2" xmlns:asp="#unknown">
ContentPlaceHolderID="ContentPlaceHolder2" runat="Server">

Some content on page

Hope it helps. Smile | :)

I am trying to find a way to display the contents of multiline textbox on a print preview page to display and print the entire contents of what the user has typed in. Once the user types in data in the multiline textbox, the data is stored in a SQL database and then retrieved to be displayed on a print preview page to be printed? Any ideas? Sorry if the question is a little easy for some of you but I am a newbie to C# and .Net prgramming. Thanks is advance.

Images not showing up

I can't figure why my images are not showing up on my web form - instead, there is that little icon indicating the image is there (otherwise, it would be a red cross).
I vaguely remember it happened to me a while ago while working with images - but don't know what it was.

Any idea? thanks.

I think the problem is with image path. Run you web site, Right Click on Red Cross Icon, Click Properties. Or check the same from View Source. Now Compare the path of original source and the current source.

Hi all,
I am facing a strange problem regarding session variables. I developed a website where a kept the login information in Session variables. It worked fine but now Session is not maintained i have checked after response.Redirect the session is lost and the value is null on the redirected page. I have searched a lot and tried many solutions but useless. I have only one session variable which is used to store the user name to display it on all pages and allowing some login based functionality.

Please help me in this issue.
Looking forward to hear a solution from codeproject.
Thank You

What is the SessionState Mode[^] in your web.config? Is it set to off?

Be careful, there is no Undo Button(Ctrl+Z) in life.

Accessing an image on the web form

Ekjon27-Jan-09 7:41

Ekjon

27-Jan-09 7:41

I know it's pretty basic.

I have some image controls on a page.
User will upload the images and the images will show up in the image controls as they are uploaded (there is a max number they can upload).

I was trying to access them to see if imageurl is empty - so I can take the first control to put the image, then the second one and so on.
But it's not working. Here's what I am trying:

foreach (System.Web.UI.WebControls.WebControl webctrl in this.Controls)<br />
{<br />
    if (typeof(webctrl) is Image)<br />
    {<br />
        if (webctrl.ImageUrl.Equals("") == false)<br />
        {<br />
            ++count;<br />
        }<br />
        else<br />
        {<br />
            img.Visible = false;<br />
        }<br />
    }<br />
}

Any idea? Thanks.

Databinding to dynamically created textboxes

Hallo,

I have a DataSet from 2 DB tables, and i want to databind some textboxes(say N, created dynamically) at runtime.
Is it possible to have 2-way databinding without using gridview or reapeater etc.
That is, i have a set of textboxes and labels in a table. The textboxes should implement 2-way databinding.
Thanks

drop www from url

munklefish27-Jan-09 5:03

27-Jan-09 5:03

Hi,

Can anyone help me with the following problem please;

I need to drop the 'www' part of a url whenever it is entered by a visitor. So for example if they type 'www.domain.com/' it goes to 'domain.com/'. Likewise it should do the same for specific files and folders eg 'www.domain.com/files/test.jpg' should redirect to 'domain.com/files/test.jpg'.

The updated domain name should be shown in the url.

I am running this on IIS on a dedicated machine over the web. I using the 'redirect' function in IIS i can only get it to redirect to a specific url rather than the exact corresponding file / domain location.

WOuld it be better to do this with a .Net config file?

Help greatly appreciated.

Thanks!!!
