DataSource Controls :: How To Use A Property Of An Object In Asp:SessionParameter

Jul 20, 2010

I am trying to get an asp:SessionParameter of a SelectParameters, to use a property of an object in session
instead of having a string in the session like Session["CustomerID"]

Something like Session["Customer"] where the property is ((Customer) Session["Customer"]).CustomerID)

My code:

<asp:sqldatasource id="SqlDataSource1" runat="server" connectionstring="<%$ ConnectionStrings:DBConnectionString %>" xmlns:asp="#unknown"> SelectCommand="SELECT * FROM getStoreCustomers (@customerID,@week,@day)"
ProviderName="System.Data.SqlClient">
<selectparameters>
<asp:sessionparameter name="customerID" sessionfield="Customer" /> ?????? (what is the syntax to pass the property here?)
<asp:controlparameter controlid="ddWeek" defaultvalue="-1" name="week" propertyname="SelectedValue" /> <asp:controlparameter controlid="ddDay" defaultvalue="-1" name="day" propertyname="SelectedValue" /> </selectparameters>

The class I use is like any other class (but serializable)

[Serializable]
public class Customer
{
public int CustomerID
{
get;
set;
}
}

DataSource Controls :: Pass Object As SessionParameter In ObjectDataSource?

Dec 28, 2010

Is it possible to pass a domain object as session parameter in an ObjectDataSource. I'm doing this:

<asp:ObjectDataSource ID="ParticipantsDataSource" runat="server" OnInit="SqlDataSource_Load"
SelectMethod="LoadParticipants" TypeName="SB.Web.units.Players">
<SelectParameters>
<asp:SessionParameter Name="user" SessionField="User" Type="SB.BusinessLogic.DomainEntity.User" />
</SelectParameters>

Apr 26, 2010

I am having an issue when trying to update a ModifiedDateColumn in the database via LINQ.

DataSource Controls :: Dropdown List Causing Error When AppendDataBoundItems Is True

Jul 22, 2010

I have a dropdown list where the user can select a name, on change event populates a Session variable and at the same time populates a formview with the full record detail. I want to add a List Item that states "Select Name" but when I add this the page errors. Input string was not in a correct format.

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.FormatException: Input string was not in a correct format.

Because the value returned from the dropdown list box is a string and not a numeric equal to the first name in the list.

AppendDataBoundItems is = true
AutoPostBack is = true

because I want to update the page as a differnent name is selected. I guess I need to not load the form until an actual first name is selected. Uncertain how to prevent the Formview from loading at page load an until a name is selected and not when the dropdown is set back to "Select Name"

DataSource Controls :: Update Datatable Changed Rows Only?

May 24, 2010

I am using untyped database bind to gridview in an edit form. Now user makes some changes to that datatable (update, delete, insert). How do I detect which rows he changes and which rows he deleted (so I drop them from DB). I know it can be done easily via table adapters but I am supporting a previously built app using untyped datatables/datasets.

DataSource Controls :: Update Only Changed Or Insert New Rows In Datatable?

Mar 4, 2010

Existing records can be updatedNew records can be insertedAll existing records can be deleted & new ones can be insertedExisting records have a primary key field
New ones are just blank inserts

All this detail is stored in a data table. On form update I only want to update existing (only modified rows) & insert new rows. I have gone about loading the changed records in a new data table

DataTable changedRecordsTable = dataTable_old.GetChanges();

How do I compare it with all the records in the old datatable and pass them to the save query ?

MasterPageFile Causing Error?

Aug 12, 2010

I'm trying to use a master page in my website. I created a page and then created the master. I then added the tag MasterPageFile="~/master". I'm guessing that I need to do something to my main page, because I've now started getting the error:

The page contains markup that is not valid when attached to a master page

My main page is as follows:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" MasterPageFile="~/my.master" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<body>
<form id="form1" runat="server">
<div>
</div>
</form>
</body>
</html>

I tried deleting the tag thinking that this might be the issue. Can anyone point me in the right direction?

C# - Migrating From Website Project To Web Application Project In Visual Studio 2010 Causing All Controls To Throw Error?

Mar 29, 2011

I recently updated my VS2010 website project from .NET 3.5 to 4.0. Everything was working fine in the website project. Today I decided to migrate the website to a web application project as I have learned this is the best way to work in .NET. I split out all my class files into a separate class library and copied all my other content into my new project. Then I updated all the references and web.config.

When I build the class library, everything works great. The problem is happening when I try to build/debug the web application project. It is acting like all the controls are missing and it is also throwing a bunch of compile errors about the public properties I have in my master pages.

Control errors: "The name 'INSERT CONTROL NAME HERE' does not exist in the current context"

Master page errors:'System.Web.UI.MasterPage' does not contain a definition....

It is giving these errors for every single control and master page property in my entire solution.I notice when I add a new web.form to this project, it also adds a filename.aspx.designer.cs file in addition to the .aspx and .aspx.cs file. My existing files do not have these extra files since they were created in a different .NET version.

UPDATE: It seems I was missing the step where I need to right click on the new application folder and select "Convert to web application". I just did that and it seems to be a little bit better...

Now it is choking on Literals that are inside single quotes:

<div class='<asp:Literal ID="CssClassLiteral" runat="server"></asp:Literal>'>

It doesn't see this literal when it does the conversion... Is the above valid code or should I implement that functionality another way?

Downloading File Process Causing Error?

Mar 11, 2010

In my ASP.Net page, I allow users to download files from the server. If the file is of even a moderate size (does it with a 40 meg file, for example), when downloading, it fails with the error message:

"Insufficient system resources exist to complete the requested service".

I've checked out the server, and it's quiet (CPU, RAM, Hard Drive, Task Manager Processes, etc all very low in their numbers).

I've run the code from several client machines and I'm getting this error message no matter where I run it from.

Event Causing Error But Can't Catch Exception

Apr 22, 2010

A developer has created a custom control in ASP.NET using VB.NET. The custom control uses a repeater. In certain scenarios, the rpt_ItemDataBound event is encountering a data error. My goal is rather than having the user see the yellow screen of death, give the user a friendlier error explaining exactly what the data error is. I figured I would be able to use a Try/Catch block as shown below throw the exception, however, it appears that the event has nowhere to be thrown to and stops executing at the "End Try" line.

Protected Sub rpt_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.RepeaterItemEventArgs) Handles rpt1.ItemDataBound, rpt2.ItemDataBound
Try
ProcessBadData...
Catch ex As Exception
Throw ex
End Try
End Sub

In VB.NET, I can find where the repeater's DataSource is being set, however, I can not find a DataBind event. how I can capture the exception in this ASCX control so I can report it to the user? Edit: The stack trace looks like this. There is another repeater within the repeater that is actually causing the error (rptOther) and I'm able to catch the error, but I can only throw it to the rpt_ItemDataBound. I can't figure out how rpt_ItemDataBound is getting called without a DataBind event.

Javascript Is Causing JQuery UI Error In Firebug?

Mar 29, 2011

So I am getting the following error in firebug regarding jQuery UI. It would be as simple if it was a matter of a process-of-elimination on the JS on the page, but there is allot of JS as well as some on the page and some on the site.master.

ERROR

.addClass("ui-icon ui-icon-closethick").text(m.closeText).appendTo
is not a function

Is there a way in Firebug to see what javascript is the initial caller?

C# - Send Server.UrlEncoded XML In Querystring Causing Error?

Apr 23, 2010

I'm trying to send a string of XML as part of the query string. Normally I'd POST this XML but I'm sending it to a 3rd party system that I can't POST stuff to. So, as it goes, I need the 3rd party system to request the services of one of the pages in my system. (explanation: the 3rd party system produces PDFs of my web pages. I give it a URL to my page, and it PDF's that page. So, the XML file contains data that I need to generate the page) Anyway, I'm getting my query string as follows:

string data = Server.UrlEncode(xmlSnippet.ToString());
string sFullUrl = urlString + "?data=" + data;

I give the 3rd pary system this URL, and it calls my page.. except the request doesn't reach the page. It's failing into the Application_Error handler with this message:

"A potentially dangerous Request.QueryString value was detected from the client (data=[my XML data])" As I know the data I'm sending is safe, is there any way I can make this work?

SQL Server :: Connection To Database Expires Causing An Error?

Aug 9, 2010

I have an asp.net web page which works with a database. When I first upload it I never disposed the connections so after using the different modules of the application for sometime it would suddenly stop working saying the connection pool filled or something like that.To fix it when a user clicked a button I opened the connection, tell the database what I needed and finally disposed the connection.

This seemed to fix everything, in fact you can work with application all you want, the problem comes if you stop using it for certain time.So for instance, I have a module in my webpage where user can capture information for a certain product. When the user clicks in one button the info gets into the database. If the user is continuosly capturing data everything works fine, but if it goes for about 10 min when he clicks the button he will receive an error. To fix this the user has to log-in again.

Every module opens a connection to the database to verify the user identity, but then after it verifies it I dispose the connection so I don't think there is a problem.

AJAX :: Greater Than Symbol Causing Internal Server Error 500?

Feb 8, 2011

If a user enters "<" or if it already exists in a textbox inside an update panel, I am getting "internal server error 500" during post back. I believe the page suspects a HTML injection and is attempting to stop it. I could use Page.EnableEventValidation to avoid it but I really don't want to do that. Is there any other way, I could resolve it (like replace < with > or something like that)?

Update:

This is happening in a textbox inside a gridView.

C# - LINQ Union With BIT Column Causing Specified Cast Is Not Valid Error?

Mar 8, 2011

I have a complicated join between a few tables but I have managed to replicate the error using linqpad and the small tables below. There are references between the COLNAME column and the YAXIS column and also between COLNAME and XAXIS that is not explicitly defined.

The error is "Specified cast is not valid", which originally I wasted time thinking the problem was converting the data returned to my object in VS 2010, but the error also happens in linqpad with no defined object. It seems insane that a bit column would cause this problem. If I change the column type to a VARCHAR it works fine. If I run the generated SQL from linqpad or sql profiler that also returns fine.
