VS 2008 - Why Getting Object Reference Not Set To Instance Of Object

Jan 21, 2013

I added a panel and a button to a page and worked fine. I then moved it to a master page and created a web content page to use the laster page and I get Object reference not set to an instance of an object.

Designer page:


style="background-image:url('home16.png'); cursor:hand; background-repeat:no-repeat; background-position:left; padding-left:6px; background-color:#E2E2E2;"
Runat="server" BorderStyle=None Text="Home" Width="90px" />

style="background-image:url('chart16.png'); cursor:hand; background-repeat:no-repeat; background-position:left; padding-left:6px; background-color:#E2E2E2;"
Runat="server" BorderStyle=None Text="Charts" Width="90px" />

[Code] ...

Code page:

Dim Menu1Color As String = "#C6C6C6"
Dim Menu2Color As String = "#E2E2E2"
btnHome.Attributes.Add("onmouseover", "this.style.backgroundColor='" & Menu1Color & "'")
btnHome.Attributes.Add("onmouseout", "this.style.backgroundColor='" & Menu2Color & "'")
btnCharts.Attributes.Add("onmouseover", "this.style.backgroundColor='" & Menu1Color & "'")

[Code] .....

It works fine in a reguler web form but not in the master form.

Using A Response Object Within A Class Library

Dec 29, 2010

My problem today is that I am having trouble shifting some functionality, that is being used in multiple applications, from the applications themselves to a class library I have started building. The issue comes in the fact the code was written to utilize Response objects as seen below...


This is all currently within a function called "DownloadDocument". I continue to have issues running any of the Response object functionality. I usually get the error saying, "Response is not available in this context", is there anyway to use a Response object in a class library file?

WCF / ASMX :: Webservice Client Response Object Not Getting Populated

Mar 29, 2011

There is an external (Java based ) web service that i am calling. I've added my service reference and verified that Reference.cs has been generated.

Then i call my service form my client website like such:


But my response object is mostly null after it receives the response. The properties that should have values do NOT.

When i look at Trace viewer, the SOAP request is correct and the SOAP response is correct. I get back a valid soap response with all the data i need it's just not making its way back to my response object. I've tried regenerating the proxy many different ways (svcutil) with no luck.

Example of what is in the response object (good data which is not making it's way back to my response object):

<ogc:Spatial_Capabilities><ogc:GeometryOperands><ogc:GeometryOperand>gml:Envelope</ogc:GeometryOperand><ogc:GeometryOperand>gml:Point</ogc:GeometryOperand><ogc:GeometryOperand>gml:LineString</ogc:GeometryOperand><ogc:GeometryOperand>gml:Polygon</ogc:GeometryOperand></ogc:GeometryOperands><ogc:SpatialOperators><ogc:SpatialOperator name="BBOX"></ogc:SpatialOperator><ogc:SpatialOperator name="Overlaps"></ogc:SpatialOperator></ogc:SpatialOperators></ogc:Spatial_Capabilities>

Why isn't the SOAP response making its way back to my response object?

Web Forms :: HTML Source Code In Response Object?

Jan 1, 2011

I am creating a web application that allows a user to download a csv file of a gridview. However, after looking at tutorials online such as http://www.aspsnippets.com/Articles/Export-GridView-To-Word-Excel-PDF-CSV-Formats-in-ASP.Net.aspxand such, I successfully got the table I wanted but there are HTML content appended to the table as well.There was also a similar problem being brought up on the forum,http://forums.asp.net/p/1528174/3692826.aspx. The solutions didn't help me much though. However, I am not really sure how Handlers can benefit this. Furthermore, I don't want the user to be navigated to a blank page just to download the csv file. I tried to debug and insert removal code to remove the html code before the response object is being wrote out but seems even at the end of the writing method, the response object seems to be holding just the table content only.

AJAX :: Ajaxcontroltoolkit.dll Version Confusion

Mar 11, 2010

I see that I have version 3.0.20229.0 of ajaxcontroltoolkit.dll on a server and on my local machine I have version of ajaxcontroltoolkit.dll in a AjaxControlToolkit-Framework3.5SP1 directory. So does 3.0.20229.0 correspond to 3.5 pre sp1?

I found the following at http://www.ajaxcontroltoolkit.com/Default.aspx:

This release includes over 10 patch fixes provided by members of the Toolkit community. We would like to specially thank all the patch contributors for their effort which helped make this release possible. We recognize their names on the

Toolkit Patch Hall of Fame.

Setting up the environment to use the Toolkit: This Toolkit release targets two different versions of the .NET Framework:

Version 3.5.20229 for .NET Framework 3.5 and Visual Studio 2008:
Download the AjaxControlToolkit-Framework3.5.zip or AjaxControlToolkit-Framework3.5-NoSource.zip.

Version 1.0.20229 for ASP.NET AJAX version 1.0 and .NET Framework 2.0:

Download the AjaxControlToolkit.zip or AjaxControlToolkit-NoSource.zip.

Note: Toolkit version 3.5.20229 is only for users who are building on top of .NET Framework 3.5 using Visual Studio 2008. If you are using .NET Framework 2.0 and Visual Studio 2005 then you should use
Toolkit version 1.0.20229.

It sounds like the Toolkit version does NOT correspond to the version of ajaxcontroltoolkit.dll.

VS 2008 - Update Data But Don't Want To Use Response Redirect

Jul 5, 2011

I am just beginner to ASP.Net, want to update data showed in gridview. While clicking on Edit in gridview, data should go to controls set above the grid view like textbox,dropdownlist, fileuploader control.

I am using OnRowCommand="gvContent_RowCommand" while updating.

But generally i pass row id to pass values from grid view to controls.

For that i use : Response.Redirect("IJPUpload.aspx?id=" + id);

then on page load I used : if (string.IsNullOrEmpty(Request.QueryString["id"]) == false)

Id = int.Parse(Request.QueryString["id"]);
btnSubmit.Text = "Update";
Id = 0;

But Now I dont want to use : Response.Redirect("IJPUpload.aspx?id=" + id);

DataSource Controls :: ObjectDataSource And Update Confusion

May 16, 2010


I'm attempting to develop an n-tier web application that makes use of the ObjectDataSource on a page. The page shows the classic 'user details' page to allow create, read, update and delete actions for an object within the users collection. Let me explain
that again as I think it might be the root of my issue. I have a class named 'user', I also have a class named 'users' which exposes a list of 'user' objects. It's this 'users' class that is the source of my ObjectDataSource control.

What i'm hoping to have happen is that the page will display a 'user' object from the 'users' class (which it does) and that the end user can then amend the values in a formview before updating them (it kind of does this). The problem I'm running into is
that all the 'user' objects are getting updated with th ealtered values and not just the currently displayed object. I suspect that this has something to do with the web being stateless, but i'm going 'round in circles trying to figure out where i'm going

I can post code if required, but what i'm looking for is a decent (read as: easy to follow/understand) site where I can get a better understanding of what i'm supposed to be doing.

My environment is VS2010, C#, .NET 2.0, but I don't think the environment is the issue, merly the chair-keyboard interface.

I have a few pages that need to use SSL and I am confused bc I read you should set the forms authentication section in the web.config to use SSL. so if this is the case, the user logs in (login page is using ssl) the forms auth cookie is created and now if i redirect to the non ssl enable home page, does this mean the auth cookie will not be transmitted, so i can't display like a welcome module or know the username of the user who logged in?
