Web Forms :: Checking For Null Value In Window.location.pathname
Feb 16, 2011I use the following code to get the file name out of the URL.
[Code]....
This works fine if there is actually a page that shows up after a '/', I would also like to check for when there is nothing showingup after the '/'. My alert above shows nothing to be there, but how do I chack for the nothing. I have tried the folloiwng, but for some resaon it just ignores me. If I do an if statement, it doesn't pick up that there isn't anything there.
if (sPage = '') { alert(sPage);}
Even though there isn't anything there, it won't show the alert and acts as if there is actually something there.

Checking For Null Values
Jan 28, 2010protected void rptNavigation_ItemDataBound(object sender, System.Web.UI.WebControls.RepeaterItemEventArgs e){
if (!((e.Item.ItemType == ListItemType.AlternatingItem) || (e.Item.ItemType == ListItemType.Item)))
{return;
}string Name = string.Empty;
if (IsDBNull(e.Item.DataItem["FullName"])) {
Name = String.Empty;}
else {Name = (string)(e.Item.DataItem["FullName"]);}
Literal ltlLiteral = (Literal)(e.Item.FindControl("ltlLiteral"));

Error While Checking Url - Key Can't Be Null
Sep 14, 2010.NET noob here (as in I know next to nothing, I'm trying to pick up some of the scraps left by my developer). Ok, I am getting this error on a number of my .aspx pages: Error while checking url '/': Key cannot be null. Parameter name: key Interestingly, I get this on my homepage on which the only .NET code is in the form of two includes, e.g: <% Response.WriteFile("/includes/footer.aspx") %> These includes in themselves only contain HTML, so I assume the issue can only be related to these or a configuration issue?

Forms Data Controls :: Displaying A Null Or Empty Cell For A Null Datetime Database Value In Gridview?
Dec 6, 2010I have setup my business object to have a create_date and edit_date members both datetime datatypes. My company want to display the create_date and edit_date fields in a gridview for each transaction. The problem i have is that after insterting a record it will have a valid create_date but no edit_date and when displayed in the gridview it defaults to datetime.minvalue (My default). How on earth do i show an empty field in my gridview for a null datetime field in the database?
I am using similar architecture to the Imar Spaanjaars example of a tiered solution. With a few small tweeks it has worked well for me for ages. I am passing a List<Database> to my object datasource which connects to my gridview.

Forms Data Controls :: Date Format In Aspx Page?
Nov 2, 2010I have to display a news component peice in our website's homepage. The news information (date and news) is retreived from the db and I have queried to retreive that info now. My question is really simple --> How do I display the news with the timestamp in this specific format:
Database has it in this format:
2010-06-21 00:00:00. ----News blah blah A
2010-06-18 00:00:00. -----News blah blah B
2010-05-21 00:00:00. -----News blah blah C
2009-04-15 00:00:00. -----News blah blah D
I need the above information to be displayed in the following format:
2010
June
06/21/2010 - News blah blah A
06/18/2010 - News blah blah B
May
05/21/2010 - News blah blah C
2009
April
04/15/2010 - News blah blah D
I am using labels like this and few date formats which would extract like this, but some coding to retreive the earliest news first depending on the yr / month and date would be great.
asp:Label
ID="Label1"
runat="server"
Text='<%#
Eval("EffectiveDate", "{0:yyyy}")%>'
Font-Names="timesNewRoman"
Font-Size="10pt"
ForeColor="black"
Font-Bold="true"></asp:Label></td>

Forms Data Controls :: Lighten Too Many GridViews In One Aspx Page
Oct 30, 2010the project I'm working on has become quite bigger then expected. And now I have pages containing about ten different GridViews (and it is likely to increase!!), each one with its own EditItemTemplate, ItemTemplate, FooterTemplate, style, properties, etc. And, of course, in the code-behind (C#) each Grid has its events handled. You can imagine: it is a mess, playing with visibility of each one, ImageButtons to hide them, further buttons for other actions. I decided to handle only events in the code behind, while using partial classes and additional classes for the rest of the code (SQL queries and everything else), but still, it's gettin a mess.
Well, my question is: is there a way to, how can I say, have a kind of separate files, where these objects are deployed, and from where I can reference them when running the application. Or, if it exists, a way to lighten aspx page and asp.cs pages. I know it's part of the job, so here the question is just intended to investigate whether a possibility to "distribute" the objects used in a web page exists.
