Problem setting up an Object data source for Forms view

Tina P23-Oct-08 18:14

I'm trying to set up an object data source which will be used to populate a text box for instance. The problem that I'm running into is that the object's method that does the actual query takes a parameter (ID). So I need to set

&lt;pre&gt;

&amp;lt;asp:ObjectDataSource ID="odsCities" runat="server" SelectMethod="CitiesList" TypeName="WEBSWAPP_BLL.Demos"&amp;gt;
                            &amp;lt;SelectParameters&amp;gt;
                                &amp;lt;asp:ControlParameter ControlID="?????" Name="ProvinceID" PropertyName="AssemblyID"
                                    Type="Int32" /&amp;gt;
                            &amp;lt;/SelectParameters&amp;gt;
                        &amp;lt;/asp:ObjectDataSource&amp;gt;
&lt;/pre&gt;

Now the problem is that the value that needs to be passed to the object is the assembly id but it's been retrieved from a drop down list which is located on the page itself. Now this new datasource that I'm setting is on a separate user conrol (.ascx file). So I can't use the drop down list from the page itself...whats the best way to accomplish that?

Thanks

make a public property in the user control and pass the parameter to that user control.

MULTIVIEW - SetActiveView should be automatically set by PageLoad using a SessionVariable called "LinkID"

AfricaTwin23-Oct-08 11:24

Hello,

anyone out there who can help ?

Page1
MenuControl with different Hyperlinks to Page2

Page2
Multiview - which should now change from default-view to hyperlink-related views.

Normally it should work with a script on page_load of Page2 and a session variable. But I really don't get the script working fine.

Thanks in advance

Please check your code properly.I think your form is not submitted properly or the newvalue is not assigned.You can check it by using javascript that the variable value changeed before submiitng the form or not for verification.

System.Data.OleDb.OleDbException: 'Y:\Macros\WFAC' is not a valid path

I have a site that is accessing a database housed on the local machine. The database has linked tables that are linked to files on a server. When I add a gridview that dispalys results associated to those linked files on the server I get the following error message:

'Y:\Macros\WFAC' is not a valid path. Make sure that the path name is spelled correctly and that you are connected to the server on which the file resides.'
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Data.OleDb.OleDbException: 'Y:\Macros\WFAC' is not a valid path. Make sure that the path name is spelled correctly and that you are connected to the server on which the file resides.

I am using VS 2008 to build the site and when I test it in VS2008 it works fine, but when I try to pull it up outside of VS I get this error. I verified the path is right, but there is some issue reading the linked file "'Y:\Macros\WFAC' " this is within the DB that is on the local machine and not part of the acutal asp.net code?

Does anyone know how I can clear this error?

"Y:\Macros\WFAC" I dont think this is name of any file. it seems to be path to a folder. if WFAC is name of the file then give its extension.

"Y:\Macros\WFAC" is the foler where a spreadsheet is housed. This spreadsheet is link to my database. I am trying to display a query in gridview from this database but it is giving the above error. I am not trying to access anything in "Y:\Macros\WFAC" directly from the webpage, but still get the error message. The database is on my local machine and "Y:\Macros\WFAC" is a remote server.

How to raise Session_End event at Global.asax if I use SQLServer for session state.

Hi,
How to raise Session_End event at Global.asax if I use SQLServer for session state. I want to clean up some data when user click X at their browser or if their session is expired.

Any help will be appreciate.

Thanks

Then you need to use the Javascript onunload event and make a request to the server telling it that the user is leaving the page. You can't use session state to catch when the user is leaving, as the server session doesn't end when the browser is closed.

Despite everything, the person most likely to be fooling you next is yourself.

Custom ExpressionBuilder + ParseControl. No Joy? [modified]

mgkr23-Oct-08 4:17

Using a custom ExpressionBuilder doesnt seem to work with ParseControl (dynamically adding controls, that are using the custom ExpressionBuilder)

Works fine with the build-in Resources ExpressionBuilder though.

Anyone have a solution/workaround for this?
Or even an explanation for why it doesnt work.

Example

protected void Page_Load(object sender, EventArgs e) {
  string s = (@"
    <hr />
    1: <asp:Label ID=""Label1"" Text=""<%$ Resources:language, Greeting %>"" runat=""server"" />
    <br />
    2: <asp:Label ID=""Label2"" Text=""<%$ IHLPResource:Greeting %>"" runat=""server"" />
    <hr />
  ");

  Control ctrl = ParseControl(s);
  Page.Form.Controls.Add(ctrl);
}

1: Gets rendered just fine, while 2: fails (no error, the value just doesnt get rendered)
ie. the output is:

1: Hi 
2:

(2: should say "\\\Output from custom ExpressionBuilder///" - See code below)

If I simply add the above to the aspx page, it works fine (ie. my custom ExpressionBuilder is not the cause of failure)

This will give you all the dates in the current week - you will need to adfjust it depending on what your starting day is, this assumes Monday.

DateTime curr;
DateTime start = DateTime.Now.AddDays((int)DateTime.Now.DayOfWeek * -1);
for (int c = 1; c < 8; c++)
{
      curr = start.AddDays(c);
}
