Compilation error after inserting script

Posted By:      Posted Date: September 21, 2010    Points: 0   Category :WPF

I have a one page ASP.Net site; there is no separate code-behind file.  It pulls its data from a SQL ODBC connection; All was well, until I tried to include script to change the color of the row, based on a condition.  Normally, the backcolor is black; and the forecolor is white; the forecolor should change to blueviolet when the field "flex_in" is not null.  Here is the code:


<%@ Page Language="C#" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<script runat="server">

Inserting personal error message in ValidationSummary



I am creating a web form that requires a lot of validation. I use many of the validation control in asp.net already like RequiredFieldValidator and CompareValidator. 

My Problem: after my custom validation for the value entered return an error message, and I pressed enter key when the field is empty, my custom error message is overlapped by my ValidationSummary. 

Setting my custom error to visible = false on button click also does not seem to work as it requires for me to enter the value first.

This made me think, is there a way to insert my custom validation inside the ValidationSummary as an error message like for other validation control?

Thanks in advance

Cast error when inserting record with Linq (to Sql)



I'm getting  the following error message: 

Unable to cast object of type 'System.Data.Linq.DataQuery`1[Username]' to type 'Username'.

I've been searching but can't find a solution.  This particular table has 4 columns. The first column is the int indentifier.  Column 2 is "username" (varchar50) and is the primary key.  Column3 is "userID" (uniqueidentifier) and column 4 is "active" (varchar5) .

            Dim dc As New DataClassesDataContext
            Dim c3 As New Username With {.userID = userGuid, _
                                    .username = userCustomName, _
                                    .active = "False"}


        Catch ex As Exception
            Throw ex
        End Try


All my server-controls became unrecognized!!! like there's compilation error or web.config missing!



please help - the problem is in post subject.

I have lots of warnings with following text:

"Warning 10 Element 'HyperLink' is not a known element. This can occur if there is a compilation error in the Web site, or the web.config file is missing. C:\Users\Pavel\Documents\Visual Studio 2010\WebSites\BioWebSite\ToScientist.aspx 26 18 C:\...\BioWebSite\" 

But web.confg is there! And there's no compilation error!

Site builds just fine. And If I upload it to my hoster - it works!


But with all these errors I cant add controls to pages - VS2010 adds hyperlink without ID, and intelisens stoped to work.

Strange, but in my other project (web-application) I have no such difficuty.

ssrs 2008 R2 - report parameter with no default set throws java script error

We have recently upgraded from SQL Server 2008 to SQL Server 2008 R2....I am experiencing a problem with my report parameters on my SSRS reports. It seems that my report parameters that I do not have a specified 'default' value throws a java script error when I try and run/render the report under R2.  As soon as I put a 'default' value on the report param, everything is fine.  However, that is not the behavior we need for our reports...the user needs to pick their selection. Can anyone shed some light on this, it seems to be an AJAX problem...I need to be able to have report parameters with a list of values, but no 'default' value on the parameter.

SQL Server Powershell script error!

Hi, I get the following error while trying to execute a powershell script. New-Object : Cannot find type [Microsoft.SQlServer.Management.Sdk.Sfc.SqlStoreConnection]: make sure the assembly containing this type is loaded. I'm trying to implement policies across different sql server instances from a primary instance.

Named Pipes provider error - backup script

I have a couple of installs of SQL Server 2005 Express.  One thing it doesn't provide is an agent to schedule jobs so I read where you can use Windows job scheduler to execute a batch job to in turn run a sqlcmd file.  I have that working on one server but on the other server I get the dreaded Name Pipes provider error and it goes on to talk about it may not be setup to allow remote connections.  If I check using Surface Configurator it is set to allow remote connections using both tcpip and named pipes.  To my knowledge all I want it tcpip but I enabled named pipes in an effort to get things working. About the only difference I can see is on the working system the database is a named instance (ie. Servername) versus default instance on the non-working system which shows up as (Servername\SQLEXPRESS).  Hopefully I have my terminology right here. Any tips on how to troubleshoot?  Does it depend on the username I am using?  Domain admin or local server admin or what have you? I should mention I can execute the backup script and it does work.  It is when I run the batch job that it fails. The batch job just says "sqlcmd -i d:\MSSQL_Jobs\backup.sql -o d:\Logs\sqlbackup_output.txt"

Duplicate column error in script

Hello, I have a new database server and I created a new database and now I'm trying to run a script that's supposed to create all the tables from the previous database server. The script is an accumulation of various changes I have made to the old database since the start of the project in order to implement a variety of features, so it has this pattern: ALTER TABLE X DROP COLUMN Y; GO and later in the file: ALTER TABLE X ADD Y int NOT NULL; GO When I run the script, I get a duplicate column error message for the table and field, although I first dropped the column and then added it again. I suppose I have to do some kind of flash after the drop and before the add, but isn't the GO supposed to do that? If not, how can I flash it in the script? Thanks.

ScriptManager CompositeScript Error: A script reference cannot be included multiple times in composi

I am getting the following error using the CompositeScript feature of the ScriptManager.  I have ScriptManagerProxy in several different usercontrols that use CompositeScript to add whatever JS files they need.  Sometimes there are duplicates which would get removed by the script manager, but that is not happening with the Composite Scripts.  Looking at the stack trace, it calls RemoveDuplicates but for some reason it doesn't do so.  Is this a bug?  Is there a workaround or a hotfix? Thanks! A script reference cannot be included multiple times in composite script references. Stack Trace: [InvalidOperationException: A script reference cannot be included multiple times in composite script references.]   System.Web.UI.ScriptManager.RemoveDuplicates(List`1 scripts) +698   System.Web.UI.ScriptManager.RegisterScripts() +328   System.Web.UI.ScriptManager.OnPagePreRenderComplete(Object sender, EventArgs e) +113   System.Web.UI.Page.OnPreRenderComplete(EventArgs e) +8695102   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1029
