MVC :: Dynamically Fill An Anchor Tag At Runtime?
Mar 31, 2011
I want to create a mailto anchor tag at runtime. Is this possible? I've tried this:
[Code]....
Neither of these worked. I tried adding the "mailto:" in front of the {0}, but this just became part of the perceived URL. I read a post online about using data attributes to add the value as a property of a class, but I can't do that, as I'm stuck using .NET 3.5 for this project. I honestly didn't think this was going to be such a big deal. I just want to populate the email address of the anchor tag with a variable value.

I'm creating an quiz application which queries the database and extracts the questions and choices. I use dynamically created controls such as a checkbox list and fill the values dynamically. How do I do this? Right now I have these functions:
array_random_init(); this creates a 10 element integer array from 1-20 - extract_question(i): this extracts a question indexed at i in DB, I created the controls and set the appropriate text in this function. - validate_question(i); this is called by button_click and validates the question i according to DB.
I understand I have to recreate the controls in Page_init on postback, but what should it look like? Do I need to add "if IsPostBack" in page_init, or do I create the controls in page_init() and reset their properties in page_load when I use extract_question(i)? Also, I cannot seem to clear the selected boxes on postback, I added page directive "enableviewstate=false" but it doesn't work.

I have a SQL query that returns about 5-10 records. For each one of these records I want to query another table using values in that row as parameters and create/populate a GridView. Can I create these GridViews and SQL connections programmatically in a for loop? I mean, I can't just plop ten GridViews and SQLConnections on my page at design time because I'm not certain how many rows will be returned in the first query. What should I do?

I am trying to render a simple hyperlink that links to a named anchor within the page, for example:
<a href="#namedAnchor">scroll to down</a>
<a name="namedAnchor">down</a>
The problem is that when I use an ASP.NET control like asp:HyperLink or HtmlAnchor, the href="#namedAnchor" is rendered as href="controls/#namedAnchor" (where controls is the subdirectory where the user control containing the anchor is). Here is the code for the control, using two types of anchor controls, which both have the same problem:
[code]....
I am using the HtmlAnchor or HyperLink class because I want to make changes to other attributes in the code behind. I do not want to introduce a custom web control for this requirement, as the requirement I'm pursuing is not that important enough to justify abandoning the traditional ASP.NET link controls. It seems like I should be able to use the ASP.NET link controls to generate the desired link.

SO I have created an object data source on a page from a table adapter using the various Wizards in Visual Studio.
Its meant to query a diary Database by a DateTime parameter called diaryDate. I want to query from a date Now to the next 14 days ahead.
I want to display the entries in a Grid View when the page loads.
So I'm a bit stuck now as to how to set the two query parameters date1 and date2. I want to set date1 = now() and date2 = now() + 14 days.
How do I set those parameters when the page loads ?
Should I have used the adapter Wizard approach of do I have to write all the code in the code behind page ??
This is my datasource code'

I have a modalpopup extender that is brought up if the user presses a button. This is fine and the user can enter the data. There are a number of textboxes and dropdownlists. However, I have a gridview which I want to bring up modalpopupextender so the user can edit an entery. How can I set the data to the controls? A dynamicpopulate extender will repopulate the modalpopupextender with all the data. It doesn't make sense for me. Is there anyway I can populate the data with c#? Also can I assign two buttons to call the modalpopupextender?

Newbie in using AJAX . Programming in C# and using SQL as a database. Here is my scenario. User selects a project and I want to display the subprojects related to that project. Here is the query I use to retrieve subprojects.
"SELECT SubProjectName,StartDate,Description FROM SubProject WHERE ProjectName'"+ddlProjectName.text+"';
Currently I store the results of the query in a Dataset. I want to get the SubProjectName in the Header of the Accordion and StartDate and Description values to the text box for each accordion. ( This is what I need to do in each accordian for each subproject)
<asp:AccordionPane ID="AccordionPane2" runat="server">
<Header>
<a href="" onclick="return false;" class="accordionLink">SubProject 1</a>
</Header>
<Content>
<table width="100%" cellpadding="0" cellspacing="0">
<tr>
<td class="td_left" colspan="2">
<asp:Label ID="Label1" runat="server" Text="Start Date"></asp:Label>
</td>
<td class="td_left" colspan="2">
<asp:TextBox ID="StartDate" runat="server"></asp:TextBox>
</td>
</tr>
<tr>
<td class="td_left" colspan="2">
<asp:Label ID="Label2" runat="server" Text="Description"></asp:Label>
</td>
<td class="td_left" colspan="2">
<asp:TextBox ID="txtDecription" runat="server"></asp:TextBox>
</td>
</tr>
</table>
</Content>
</asp:AccordionPane>
How can I do this? Some code example would be great on how to creat the accordinas ,text boxes dynamically and fill the values.

I have a requirement whereby one or more image buttons need to be created in a user control at runtime. The number of buttons is determined from a database where a user can add one or more rows that contain an image for each button, so if a user adds 3 images to a table, 3 image buttons are created. Ive used this code but I get an error at runtime
The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases.
[Code]....
this is the usercontrol aspx
[Code]....
I basically want one or more buttons to render within the div in the usercontrol. Ive only got the code written for one button at the moment while I test the rendering, eventually they will be rendered in a loop of records taken from a database. Whats the best way to do this ?

I'm building an application that will be used by a number of different schools who want completely separate databases so I've decided to have multiple connection strings and membership/role providers in my web.config file. In my code, I'm trying to set which connection string and provider to use at runtime for the correct database according to the logged in user.
I'm coming into a lot of bits in my code that previously worked fine, that now don't. For example, I used to use:
[Code]....
But now that I've changed it to this, it doesn't work anymore:
[Code]....
The compiler tells me that AddUserToRole is not a member of 'r'. I've had similar problems not just with Roles but Membership too, like with calling CreateUser.
I'd still like to be able to use all these methods that I was using before which are extremely handy. I just want to be able to set the membership/role provider at runtime rather than use the default one. Am I doing something wrong? Is there a simpler way to go about this?

The following link describes the relationships between a Partial View and its parent in terms of ViewData: [URL] In relation to the text: "A partial view enables you to define a view that will be rendered inside a parent view. Partial views are implemented as ASP.NET user controls (.ascx).
When a partial view is instantiated, it gets its own copy of the ViewDataDictionary object that is available to the parent view. The partial view therefore has access to the data of the parent view. However, if the partial view updates the data, those updates affect only the partial view's ViewData object. The parent view's data is not changed"
how the parent view can make use of the new data added or existing data changed and updated, by the partial views? My question is around how to load partial views dynamically at runtime using Html.RenderPartial(...) whilst having one version of the data used and updated by the parent view and it's children.
