Error while reading values on postback

Posted By:      Posted Date: September 03, 2010    Points: 0   Category :ASP.Net
 
I have some problems with trying to read values on a postback.The fields, textboxes and dynamiclly created fields doesn't keep their values or I'm doing something wrong when trying to read the values. I get an error message: System.NullReferenceException was unhandled by user code  Message="Object reference not set to an instance of an object."  Source="App_Web_m-6qot6q"  StackTrace:       at Sikt.RäknaVärden() in C:\Visual Studio 2005\WebSites\Kalibreringscertificat\Sikt.aspx.vb:line 688       at Sikt.Button1_Click(Object sender, EventArgs e) in C:\Visual Studio 2005\WebSites\Kalibreringscertificat\Sikt.aspx.vb:line 892       at System.Web.UI.WebControls.Button.OnClick(EventArgs e)       at System.Web.UI.WebControls.Button.RaisePostBackEvent(String eventArgument)       at System.Web.UI.WebControls.Button.System.Web.UI.IPostBackEventHandler.RaisePostBackEvent(String eventArgument)       at System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument)       at System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData)       at System.Web.UI.Page.ProcessReque

reading values from config files in NUnit tests

  

One of my NUnit tests has to read in some values from config files.  In my main application this process works perfectly well, however when I run the unit test, the code that reads in the values from the config files doesnt read anything in.  Ive tried putting app.config in my unit test project (I even tried web.config) but nothing seems to work.  Are there any special steps involved when reading from config files in an nunit test ?


Reading values from data access component individually

  

Hi,

I am trying to pick data from the database through data access layer and use those values in different text boxes on the page.Basically on a click on the form, modal popup is planned to read the database and put the values into different text boxes which can be latter changed/ updated.

 What I am unable to do is accessing those values on the form itself progamatically. I will be thankful for any ideas and help.

My data access component is as follows:

cmd.Parameters.Add(

cmd.Parameters[

 

new SqlParameter ("@reg_id", SqlDbType.Int ));"@reg_id"].Value=reg_id;try

{

con.Open();

SqlDataReader

Exception caused by DataPager.SetPageProperties() on ListView (postback error)

  
 Hi, I have a issue with drives me crazy! I'm using the DataPager method SetPageProperties() to restore the current page in my listview after I navigated into a page related to a listview item. (I persist the current page in the session state) I display 10 items at a time, and there are 10 pages. Everything works perfectly for the first 100 items, .... but after I go beyond (to display pages 11 to 20), if I call SetPageProperties() to restore the proper "current" page, I cannot submit anymore anything without getting the following exception: An error has occurred because a control with id 'ctl00$ctl00$ContentPlaceHolder$ContentPlaceHolder1$m_ListViewSearchItems$lvProductsPager$ctl00$ctl10' could not be located or a different control is assigned to the same ID after postback. If the ID is not assigned, explicitly set the ID property of controls that raise postback events to avoid this error. The exception refers to the DataPager sub-controls which are not rendered the same way for first pages (1 - 10) than (11 - 21); Is that because it expect then a "previous page" button? I don't quite know what to think about it. Does anyone have a clue?

Error reading .config file in Windows Forms app - Access is denied

  
I'm attempting to read a connection string from a .config file in a Windows Forms app on a test laptop. A previous version of the application worked just fine, but now I get a configuration exception thrown - "Configuration system failed to initialize." The inner exception message says - "An error occurred loading a configuration file: Access is denied". The user I'm logged in as is in the Administrators group and there's no obvious problems with the config file. The same config file works just fine on my dev machine so it's not an issue with ordering of the XML. Any ideas would be greatly appreciated.If a response to your question is helpful or answers it please mark it as such!

Controls missing values after postback

  

I just uploaded an asp.net webforms site I've been working on to my ISP's servers. I have a simple page that allows users to enter schedule data.  The problem is that when the user clicks the Add button and I try to process the values they've entered in the textboxes and dropdownlist in the click event handler, all the values are blank. For example, there's a DropDownList called uxStartTime on the page and after postback uxStartTime.SelectedValue is blank.  However, the Response.Form[uxStartTime.UniqueID] has the proper value.  I have EnableViewState="true" in the aspx page. This all works fine on my local machine, just not on the server. Can anyone tell me what's going on? I can use the Respons.Form syntax, but it's a little more verbose and prone to typos.



Getting VP.NET code to respond to SQL Return values and Error Codes

  

I have SQL stored procedures that will return values depending on the outcome of its execution. I have the following code at the end of each of my Stored Procedures:

RETURN @siReturnValue

It would be great to be able to use this Return value after running the Stored Procedures from my VB.NET code. I have included an example of how I am running SQL Stored Procedures below:

    Public Function SearchKeyword(ByVal SearchString As String) As Data.DataTable
        Dim AerialConnection = New SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings("aerialConnectionString").ConnectionString)
        Dim MediaArchive As New Data.DataTable
        Dim reader As SqlDataReader
        
        Try
            AerialConnection.Open()
            Dim SelectMediaArchiveCommand = New SqlCommand("EXEC spSearch @keywords", AerialConnection)
            SelectMediaArchiveCommand.Parameters.AddWithValue("keywords", SearchString)
            reader = SelectMediaArchiveCommand.ExecuteReader()
            MediaArchive.Load(reader)
        Catch e As Exception
        Finally
            AerialConnection.Close()
        End Try
        Return MediaArchive
    End Function

How can I code this to respond to different Return values, or even error cod

Reading/storing values of checkboxlist in SQL (VB)

  

Hi there,

I'm trying to store multiple selected checkboxes from a single checkboxlist, but i don't know where to start.. Sealed
Imagine i have three tables: tbl_events, tbl_organisors and tbl_settings and i want to store the organisors of an event.

Each event can have multiple organisors, so each organisor should be added as a single row into tbl_settings.
I know how to bind tbl_organisors to a checkboxlist, but how do i store the results (meaning: add the rows to tbl_settings) ?

tbl_events: Event_ID (PK) and Event_Name
tbl_organisors: User_ID and user_name.
tbl_settings: Settings_ID (PK), Event_ID and User_ID

Checkboxlist:

<asp:CheckBoxList ID="CheckBoxList1" runat="server" DataSourceID="SDS_Organisors"
DataTextField="User_Name" DataValueField="User_ID" RepeatColumns="2">
</asp:CheckBoxList>

SQLDatasource:

<asp:SqlDataSource ID="SDS_Organisors" runat="server" 
        ConnectionString="<%$ ConnectionStrings:LocalConnectionString %>"

Reading in values in text file in a project solution to an array

  

Hi,

I have a tab delimited text file that has 6 columns (all integers) and 500 rows (and no column headings) called ProjectData.txt that I have added to my Windows Form Application (c#) (by added I mean I have it in my project solution). 

I have declared an array in my code called ProjectDataArray which has dimensions [500, 6].

I wish to load each column of each row into the array.

All the code I have seen shows how to do this for text files that are not included in the project solution. 

Is this easy to do?

People Picker control used in ASP.Net wizard control. Loses values on Postback?

  

I am using a people picker control in a custom visual web part with Visual Studio 2010, Sharepoint 2010.

The people picker control is on an asp.net wizard control.

On the wizard step with the people picker control, after postback the people picker control has selected values.

But when clicking the next or previous buttons of the wizard control, the people picker control does not retain its selected values.

 

Microsoft.SharePoint.WebControls.PeopleEditor pe

pe.AllowTypeIn = true;
pe.AutoPostBack = true;
pe.AllowEmpty = true;
pe.MultiSelect = false;
pe.SharePointGroup = "My SP Group Name";
pe.SelectionSet = "SPGroup";
pe.ValidatorEnabled = true;
pe.CommaSeparatedAccounts = pe.CommaSeparatedAccounts;

Any suggestions?

SQL Server 2008 r2 - Setup support files - Install error / reading from file

  

I'm installing SQL server 2008 r2 on a Win2003 R2 x86 system.

After i start the setup, the "setup support files" box begins installing, after a while i get this error:

"Error reading from file f:\1033_ENU_LP\x86\setup\sqlsupport_msi\PFiles\SqlServr\100\Setup\ewbfphdh\x86\Patch\rs2000.msp verify that the file exists and that you can access it."

I've tried another DVD, i've tried a mounted share on another machine...no go....i've tried an ISO file mounted on this server... same error.

Is there any way i can install this "setup support files" from another location? (download)

Is there a switch soo it won't install reporting services? (...i think this file rs2000.msp is from reporting services)

Thanks

Determine node type selected in TreeView and reading property values

  

I am hoping that someone can help me get past some problems I am having when using the WPF TreeView control.  I have a TreeView that at most can have 3 levels.  The levels are defined as Project, Discipline, Person which would look like the following:

+ Project

    + Discipline

        - Person

My TreeView is bound to a database using two HierarchicalDataTemplate's and then one DataTemplate (the binding is done in the XAML).

What I would like to get is the following information when selecting an item:

  1. Read the selected value (text of the selected node)
