Hi,
I am using role based authorization. Is it possible to deny access to a control using webconfig.
I have created a menu ( not from sitemap) in the master page and I want this menu to be accessible only by users in roles and not by everyone else. I know I can make it invisible in login page etc but is there any other way?
Here is a part of the web config code
<authentication mode="Forms>
<forms loginUrl="login.aspx">
</forms>
</authentication>
<location path="Admin">
<system.web>
<authorization>>
<allow roles="Admin"/>
<deny roles="Employee"/>
<deny users="*"/>
</authorization>
</system.web>
</location>

No you cannot handle the control display from Web.Config file. You can handle the URL authorization only. Thus, Menu will be visible as per set for the page. If you display all, then authorization is the way to stop them.
Ideally, you hide it if it is not accessible.

From my personal experience, i recommend using css and avoiding tables.
I prefer measurements in pixels and it makes it more sure.
check some best practices here.

Its easy to add CSS in ASP.NET, as you do in HTML. The code will be basically look like this:
<link href="css/filename.css" rel="stylesheet" type="text/css">
Or you can even place it in the same masterpage like this, inside of the head tag, you add:
<style type="text/css">
CSS ATTRIBUTES
</style>
For instance, if you are using master pages, you have to add the css links inside of it (the masterpage).
I'm not a MASTER of web development, but i can help you with something...
CSS its easy as well, gonna make some examples for you.
Lets say we have the filename.css with:
body
{
background-color: #1e1e1e;
margin: 0px;
text-align: center;
font-family: Trebuchet MS;
}
The entire webpage if I let it this way, the font will be Trebuchet MS and it will be centered.
You have 3 ways for applying CSS. By ID, by Class or by Object.
By ID:
(ASP.NET)
<asp:TextBox ID="foo"/>
(CSS)
#foo
{
color: #282828;
font-size: 12px;
font-family: Arial;
border: 1px solid #fff;
}
Here, this ASP input text will have a 1px solid white border, the color of the text inside of it will be grey, Arial and 12px size.
By Class
(ASP.NET)
<asp:TextBox ID="foo" CssClass="input">
(CSS)
.input
{
color: #282828;
font-size: 12px;
font-family: Arial;
border: 1px solid #fff;
}
This will contain the same attributes, but the only difference is that we changed them by class instead of ID.
If you have a lot of inputs its better for you to use classes rather than ID, ID is more unique related style, -when you have to change a single object style-.
Then you can also change all the inputs, all the selects, and so on of your site, like this:
input
{
color: #282828;
font-size: 12px;
font-family: Arial;
border: 1px solid #fff;
}
Where ALL the inputs will be under these style rules.
Next for you to know, is the positions, margins, paddings and floats.
Try to avoid using position: absolute or tables as one person said above, they aren't good, conceptually neither.
So the best way for you to create forms for example, is with DIVs and CSS, is even way better for reading and understanding.
After doing both ways, you realise of the quantity of lines used for nothing with tables and the worthless space they use.
Also, by using tables, each browser (firefox, chrome, opera, IE) has their own attributes for placing elements inside of rows/columns, so its not always the same way you see it in firefox than in others.
position: absolute attribute is better not to use it, as instead, try using float: left or float: right, with margin-left, margin-top, margin-right or margin-bottom properties.
The position: fixed, the one that you asked about, is to keep an element FIXED on the website and eventhough you resize the browser window, it will be mantained in the way you placed it in the window with CSS.
Hope it helps for something at least, happy designing/programming!
My best regards,
Marian.
EDITED: Oh what you can do to practice a LOT, is install the Firebug for Firefox and you can debug there in execution time, just simply "right click" in your site > Inspect Element, go to CSS tab, select the CSS file and edit it, change attributes, create new rules, etc... that's the way i learned, comparing results

Tables is an outdated method.
Use <DIV> tags and float or position them.
Can put DIVs inside DIVs and use CSS Tables for formating.
You can nest a table in a DIV, but DIV is the correct method du jour.

I would like to ask you which way is perfect when I
determine the size of tables or DIVs either pixel or the percent
actully that I know is the pixel size will not fit with all browser or computers
Is it true?

Hello Sir/Madam,
i am facing problem last two month.
so please you have sent perfect solution.
unable to connect to visual studio's localhost web server.
i tried by reinstall the webdev.webserver from
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727..
but
it is saying 'The application failed to intialize properly (0*c0000007b).
Click ok to terminate the application.
Regards,
Nand kishor

First, change the subject of your question to something meaningful.
Never, put an email id in place.
Second,
when you replace/re-install WebDev.WebServer.exe, make sure you end all instances of same in task-bar, register aspnet again.
Third, the Error:
The application failed to initialize properly (0x.....)
means
'The permissions aren't setup properly on MSVBVM60.DLL in your Windows System32 folder.'
In most cases adding permissions to this file solves problem. Check this for doing so.

Hi
I am struggling with updating data from a web page. On the page I have a DetailsView control which is bound to a table in the SQL Server database. I have enabled Editing.
One of the fields in the table is a foreign key to a lookup table (for the Referring Hospital) in the database. I would like to have a DropdownList in the DetailsView so that the user can choose the item.
I have changed the field to a TemplateField and while the field (“HospID”) is still a TextBox the update to database works. For example when I change the LastName and click ‘Update’, the update reflects in the database.
Here is the markup:
<asp:TemplateField HeaderText="HospID" SortExpression="HospID">
<EditItemTemplate>
<asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("HospID") %>'></asp:TextBox>
</EditItemTemplate>
<InsertItemTemplate>
<asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("HospID") %>'></asp:TextBox>
</InsertItemTemplate>
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Bind("HospID") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="LastName" HeaderText="LastName"
SortExpression="LastName" />
However when I replace the TextBox in the EditTemplate with a DropdownList and try to update, the changes do not reflect in the database. Even if I have just changed the LastName.
The markup for the DropdownList is as follows:
<asp:TemplateField HeaderText="HospID" SortExpression="HospID">
<EditItemTemplate>
<asp:DropDownList ID="DropDownList1" runat="server"
DataSourceID="SqlDataSource_RefHosp" DataTextField="HospShort"
DataValueField="HospID">
</asp:DropDownList>
</EditItemTemplate>
<InsertItemTemplate>
<asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("HospID") %>'></asp:TextBox>
</InsertItemTemplate>
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Bind("HospID") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
Even if I just use a basic DropdownList with no databinding the update does not work.
<asp:DropDownList ID="DropDownList_RefHosp" runat="server"
DataTextField="HospShort" DataValueField="HospID">
</asp:DropDownList>
I am stumped here so if anybody can give me some pointers it will be appreciated.
Regards.

You are connected the Dropdownlist by automatically by Database connection wizard. When program starts running the values in Database which you specified is loaded Dropdownlist. Again it will not goto database to retive the values for dropdownlist. So you can't get updated values.
Instaed of that you will write the code in separate method RetriveData() to retive the data from database and add the SqlDataReader values to Dropdownlist.
Call thet method when page load and update button click methods . Take another connection object to for RetriveData() method Open the connection when RetriveData() is called and Close at the method end.
U will get updated list evrytime.
Hope you can do the coding simple try it..

dt.Rows.Add(newrow);
}
/* Finally Bind the Constructed DataTable to Grid2 */
GridView2.DataSource = dt;
DataBind();
}

First the newbie mistakes need to be corrected. NEVER hard-code you connection strings in your code, use the web.config file. There is a section for connection strings. NEVER use string concatenation to form to the sql statement and NEVER, EVER use unvalidated values from user input.
If I understand this you want GridView1 and GridView2 to have the same data?
GridView1.DataSource = GridView2.DataSource = dt;

Haha, having trouble atm getting this to display correctly as CP keeps converting it...
You need to replace the "&" with "&" - this is the HTML escape code for an ampersand character. For a full list, see here[^].

Escape codes are a bugger to remember aren't they!
