Dear All,

I have a custom ASP:DataGrid and want to check whether to show the image column or not by first checking the existance.

The code is here but face an strange error while rendering:
<%# if (HasImage( DataBinder.Eval(Container.DataItem, "ID").ToString() ) {%>

" width="107" height="111" alt=""> <% } %>

Please Help.

Thanks,
Sassan

Well what kind of error are you getting?

This code seems wrong. You are fragmenting the if statement into two sections of <% %> and I don't think you can do that.

I might be wrong since I have always used code-behind to write my C# code, so I am not familiar with writing the code in the page itself. You need to get a second opinion on that one.

Url mapping?

Perhaps I'm approaching this the wrong way but I'm creating a "community" website to learn the ins and outs of ASP.NET. There's a news page which loads its contents from the database, the Content field of the database stores any valid (x)html as the news item (only limited users have write access to this so I'm keeping the flexibility of allowing all HTML). However it'd be nice if links could use the ~ to symbolise the application root and have these translated automagically. For example the basic (relevant) structure of the site is this:

Home
    News (~/news.aspx)
       Reports (~/news.aspx?category=Reports)
       Shoots (~/news.aspx?category=Shoots)
        WCTSA (~/news.aspx?category=WCTSA)
        Website (~/news.aspx?category=Website)
    Contacts
    ...

However there are some mapped urls going on to create nicely rememberable paths, e.g. the Reports page can be accessed through ~/news/reports.aspx but is mapped to ~/news.aspx?category=Reports. Thus the problem I'm running into is for example to link to the contacts page I could put a link <a href="contacts.aspx">Contacts</a> in the database but if this were viewed from the Reports page it would try ~/news/contacts.aspx rather than ~/contacts.aspx.

So since I'm new to ASP.NET I was wondering if there was some magic way to allow parsing of ~ urls from database fields without having to write a custom parser.

Perhaps as I said I'm going at this the wrong way and it would maybe be easier if I wrote a generic handler which could then be used as the linker, something that redirected the user, e.g. (all my handlers are under the services directory) ~/services/redirect.ashx?url=~/contacts.aspx and get this to resolve the address and redirect. Actually I think that may be the best solution.

How To Render HTML In ASP:DataGrid

17-Aug-07 3:43

Nested means one inside another (when you are talking about a page), inherits means one derives from another (when you're usually talking about classes)

You cannot put a master page inside a master page. You can probably derive a master page class from another master page class. That means that if you have a master page with its corresponding code-behind class, you can create another master page and make it inherit from the first one.

1st Master page:

public partial class Master1: System.Web.UI.MasterPage
{
......
}

2nd Master page inherits from first one:

public partial class Master2 : Master2
{
....
}

I have never done that so I don't know if it works.

Dear All,

I have descriptions in DB for a news service Like These:
<BR>This is the Short Desc</BR>

I want to render this in a grid using ASP:DataGrid with Custom Template which is a Table. Therefore I have a code like this in my <ItemTemplate> lines:

<span class="style8">
<%# DataBinder.Eval(Container.DataItem, "ShortDesc")%>
</span>

But after rendering not only the text is not bold, but all the contents are also displayed. Therefore If there exists some other HTML Tags, All of them are not interpreted and will be displayed.

Since the Database content is just read only and I can't convert the Data, please let me know how I can show the text as was decorated in the editor.

Thanks,
Sassan

Thanks Pathan,

But first the code was like the one you mentioned and the problem observed:

<asp:label id="lblSC" runat="server" text="<%# DataBinder.Eval(Container.DataItem, "ShortDesc")%>">

When I check the DB Content , The < and > Characters are HTML Encoded, Therefore The text I see is what is in DB Not the < and > character to be layout.

U can do that also in codebehind file using Server.HTMLEncode and Server.HTMLDecode method.
