I have a slight issue I awas trying to fix for 2-3 days, but nothing I try works.
The scenario:
DetailsView control in edit mode, I pass parameters to the SqlDataSourceProducts (edit.aspx?id=2) and the data source selects the appropriate data and fills in the DetailsView form.
Except two drop down lists. These two DDLs (DDL2 and DDL3) are dependent on the previous DDL (DDL1) in the DetailsView.
when the selected value of the DDL1 changes, DDL2 and 3 change their lists and get bound to the database.
The problem is: when I edit something from the database, DDL2 and 3 appear empty and when I update any other field and leave these, they get blanked in the database.
My goal is to set the selected value of DDL2 and 3 to the values in the database WHERE ID = QueryStringField="id".
I can go for not binding the data unless the field is changed, but does not sound professional and user friendly.
code:
The SqlDataSource used to select the parameters from the table and populate the DetailsView

The code of the fields that hold the DDLs in the DetailsView control

The codebehind:

I got a table in a formview where i placed lots of textboxes and dropdownlists inside the table because I need these textboxes and dropdownlists on a background image.
the data on textboxes and dropdownlists that are inside the table is unable to be saved into the database when i pressed the "submit" button. Other textboxes and dropdownlists that are not inside the table work fine. Here are the HTML code for the table:
<asp:Table ID="Table1" runat="server" BackImageUrl="~/images/DRAWING.jpg">

For some reason I seem to be unable to update my DB through the datasource. Is there anything obvious as to why this wouldn't be working?
I even added static values to the update string to see if this works but it still has an issue.

I have 2 table in database
1-Estate_free Table
2-Black_list Table
in Register.aspx users can insert their information and when click on insertButton it insert their data into Estate_free table
below is code
protected void insertButton_Click1(object sender, ImageClickEventArgs e)
{
SqlCommand _cmd = new SqlCommand("InsertFreeState1", _cn);
_cmd.CommandType = CommandType.StoredProcedure;
_cn.Open();
[Code].....
in above SP I define that if users tell or Mobile number was in Estate_free ro Black_list table it doesn't insert data into database and show 'You can just register 1 Time' and if there wasn't their mobile or Tell in those table it insert their data into Estate_free table and show 'You have been registered'.
problem is that when I enter data in database with new mobile number it didn't insert data in database and show 'you can just register 1 Time'.
I mean it never insert data in database.

I'm having a problem sorting a dropdown that I've bound to a SQL Server data source. I've narrowed the problem down to the fact that I have a static item at the top of the dropdown with the data-bound items appended afterwards. If I remove the static item (<asp:ListItem Value="-1" Text="All" />) the ORDER BY part of the select clause works fine. How can I get around this issue? What I would like is to have the "All" static item at the top of the list with the data-bound items sorted alphabetically afterwards. I'm using Visual Studio 2010 and ASP.NET 4 if it makes any difference.

Trying to explain this clearly. I have a dropdown listbox where user can select multiple names. These names are then selected/inserted into db table in a loop. Table is displayed in an editable gridview. I have a main sqldatasource1 on my aspx page with select/insert/update permissions, but because select command doesnt work with parameters of multiple values (or does it?), i resorted to using an alternative sql datasource in the codebehind in order to run the select query on the multiple values chosen from the dropdownlist to see if they were in my table.I now get this error when I go to select multiple names from the dropdown list
Unable to cast object of type 'System.Data.Common.DataRecordInternal' to type 'System.Data.DataRowView'.

i have quite big ASP.NET MVC 2 application (multiple areas, each with own routing registration) using routes like this :
/Item/12345/Detail - where 12345 is the ID of the item. The whole application just rely on that numeric IDs. But now there is an requirement (seo stuff) to make URLs look like this :
/Item/item-unique-string-name/Detail
I would love to handle this globally in some high level - for example load numeric ID before route evaluation and "replace" it in route data. But i am not sure what is the right spot for such a hack - custom MvcHandler, custom IRouteHandler, somewhere else ?

routes.MapRoute( _
"Defaultss", _
"{controller}/{action}/{id}", _
New With {.controller = "Home", .action = "Index", .id = UrlParameter.Optional} _

I'm localising a site via a Change Language control in the master page. I need to render the control with the current url you're on in each of the different languages.
So if you're on http://site.com/en/Home/About and you change the language to french, I need to direct you to http://site.com/fr/Home/About.
The localisation code works on the route data language property, so I've been trying to figure out how I can:
Get access to the current action (with all original parameters) Get the url to the current action (with all original parameters) with the route data changed.
I've tried passing the ViewContext from the parent into the UserControl, which gives me access to the route data but I can't figure out how to get the language routed url from that.

Looking at the asp.net v4 URL Routing it's easy to see how to access routing data from basically anywhere in the app.
Via: Page.RouteData.Values["blah"]
Unfortuantely the Route data always is blank by the time i hit the page on my v 3.5 implementation of routing. I was wondering if there was any way to either pass the route values to the final page so i can use them there - i really don't want additional logic in my handler file and i have loads of Routes and don't want many RouteHandlers.

I have a url that I want to map routing to:
[URL]
where tabvalue is one of: "personal", "professional", "values" or nothing.
I want to map it to a route like:
Member/Edit/{tab}
But my problem is - I don't know how to specify such constraints. I'm trying this regex:
^[personal|professional|values]{0,1}$
but it only works when I use url
[URL]
[URL]
and doesn't work for
[URL]
how to specify the correct constraint?
P.S. I'm not using MVC, just asp.net WebForms
