Forms Data Controls :: Adding Any Control Causes Web.config Failure
Feb 24, 2010
I have a brand new VS 2008 website using 3.5 frame. Default page works but if I add a chart or Gridview I get: Parser Error Message: Could not load file or assembly 'System.Web.DataVisualization, Version=3.5.0.0
in the Web.Config file the <add key="ChartImageHandler" value="storage=file;timeout=20;dir=c:TempImageFiles];" />
I am hosting on our own fully managed server - why the DataVisualization assembly is not being found. Also I was able to load the Default.aspx page until I tried to add a GridView to it. Now it too generates the assembly error eventhough I deleted it. If I comment out the DataVisualization assembly the default and test pages load - there are no controls on these pages. Ony text. Very confused. This is my first attempt at using VS 2008, I am using the trial version.

I am buidling a support call system that allows people to submit support tickets and then an engineer can respond to them.Support tickets are submitted from a formview to a database. Then the engineer looks at them from his own page which shows that particular call in a formview, he adds his comments and hits update.What I want to do is be able to add more than one set of comments should the engineer have to make more than one entry and for that I would like the control to add a column to my database table.Is there an easy way for this to be done?

I'm making an Online quiz website using ASP.NET and am using a FormView to display the questions to the user and am using Radio Buttons for the choices.
1. How to store the choices that the user selects for the questions so that I can do the scoring at the end of the test ?
2. At the Quiz page, I'd like the user to know the questions he has attempted and those that he hasn't. How shall that be done?

I need a form that displays three columns drawn directly from a database (no problems here) as well as two fields that require some complex calculations. Not only am I lost as to how to incorporate the calculations into the control, I don't know exactly how to write the calculations. I am working in Visual Web Developer 2008 with Vb.NET.
The first of the two fields should take the sum of all payments made by a given customer and divide it by a DailyMembershipRate, returning a DaysPaid variable. It should take this variable and a CustomerSince field for that particular customer and calculate a PaidThrough field.
The second of the two columns similarly requires the DaysPaid variable described above. It should subtract the CustomerSince field from the current date and return the value in days, giving a MembershipDays variable. Finally, it should subtract MembershipDays from the DaysPaid variable, again returning a value in days, and then multiply this by the DailyRate value for a Credit/Deficit field.
I realize this is a lot, but I haven't been able to find any documentation either online or in VWD or ASP.NET texts on this topic. I could really use some fellow user input.

I am currently in the process of writing a facebook type 'activity feed' for a site. Currently I am binding the last 10 items to a repeater control, which contains a usercontrol representing each item. The requirement is that when a user clicks a refresh button any new events are added to the top of the list, the previous items drop down and the equivalent number of old items drop off the bottom, all with nice slider transitions. I have put the repeater inside of an update control and are able to handle the transitions by using RegisterStartup script to drop jquery calls onto the page for the slider. However I cannot find a way to dynamically add or remove new datarows to the repeater.
I need the old items to stay in the repeater and be pushed down by the new items, so completely refreshing the datasource seems like a bad idea.I was thinking about maybe storing the datasource in the viewstate and adding rows to that, maybe with an extra column on the end which stores what transition is needed on the databind for my jquery, but there will be a 'View more items' link at the bottom of the page, so I am worried that the list could get pretty large and there would be a big problem with memory.

How do I add a web.config to a class library? I'm trying to build a data access component with two classes, one class that represents one thing and the other to perform data operations on that thing. However when I right click the project and click add item, I don't see information for adding a web.config, I just see information for adding an app.config. Maybe I'm doing this wrong? I'd like this component to be available to other asp.net apps that I will build in the future....

I have a datalist control
In it, I have a hyperlink that im binding the url, and the text to from a mysql database
here is my code so far
<asp:HyperLink ID="HyperLink1" runat="server"
NavigateUrl='<%#Bind("topicid") %>' Text='<%# Bind("title") %>'></asp:HyperLink>
Now, the problem is, the field "topicid" returns a number, such as 3. I want to add the following text before it: viewTopic.aspx?id=
So, ideally, i want something like this
<asp:HyperLink ID="HyperLink1" runat="server"
NavigateUrl='<%# "viewTopic.aspx?id=" + Bind("topicid") %>' Text='<%# Bind("title") %>'></asp:HyperLink>
But, when I do it that way, I obviously get an error.
So, is there any way to solve this problem without having to modify the database?

I am stuck in chart controls...Here is my prob... There is a ListBox containing some items...when user selects multiple items from the list box I want to generate a dynamic table with the number of columns same as that of the number items selected in the listbox. And for each selected item I want to show a seperate chart in the columns...Currently I want the same chart control for every selected item (i.e. a static hard coded chart that i will replace later by dynamic values)....I am using a method that draws a chart control using a sample dataset... I am calling it each time when a new column is created..Also the DrawChart method executes for the first column only and throws an index out of range exception! after the first execution...my code is not working...here

I have created a asp.net webpage for viewing daily downloaded newspaper, saved as a pdf file in a selected folder (~/NEWS/{0}) within the web root directory. Also i have a SQL datasource linked, where the news table has two columns viz: date and filename.
I want to create a tiled listview where the date text is visible on the hyperlink. on clicking the hyperlink, the file name is retreived for the corresponding date and the pdf file opens in a fresh page.
I have tried going to the item template in listview and replacing the label control with a hyperlink control, but then not able to successfully proceed ahead.

Scenario:
I have a Gridview where I want to handle the Sorting in a custom control that I've added to the header.
I've added this control to my GridView's Header via OnRowCreate event handling. I want the Sort Expressions to persist session to session (via Webparts Personalization)
Here is what I have for adding the custom header control to the GridView Header
[Code]....
This works out well for adding the control, but I can't get anything to persist because these controls are creating initially via postback (per the event) and re-created on all subsequent postbacks. I can't add an If(!IsPostback) because the controls are initially created on the gridview's postback (well at least thats how it's acting when I put it in there) If I were to add this control via the ASP page, not via the Codebehind, I would be able to persist the control. If I try to treat it as though everything is setup correctly, and assign my custom control's controls to [Personalizable], I get a runtime error telling me that I can only have webpartzones in or before Page_init (I'm guessing this is due to when/where the
gridview hits the OnRowCreate event). If there is some fundimental logic I'm missing, or best practices that I'm moving away from,

In a User Control, I need to add a Div to the end of its parent's page. I've done this in a number of ASPX pages, where I put the code to generate the Div and its contents in the page's PreRender event handler, and it works fine. But when I try to do the same thing in the PreRender event handler for the User Control, I get the following error:
The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases.How do I accomplish this in a User Control?

I'd like to know if there is an automated method to add e-mail settings to web.config.
There is already an e-mail set, and it's currently like this:
<system.net>
<mailSettings>
<smtp deliveryMethod="Network">
<network host="0.0.0.0" port="25" userName="whatever@whatever.com.br" password="stackoverflow" />
</smtp>
</mailSettings>
</system.net>
So what I want is:
1 - How do I add a new e-mail in there set by textboxes in the webform ?
2 - How do I differentiate which one I want to gather at the time ? could you give me a simple C# example on how to get the configs in one of the two ?
