I am designing a page for my students to practice their Latin vocabulary. I am having two problems with the design: 1) working with checkboxes, and 2) display one returned row at a time. 1) First, students select from CheckListBox1 those parts of speech (nouns, verbs, adjectives, etc.) they want to review, and then they click Button1 ("Submit"), which fires off a SELECT statement against a table named CoreVocab in a SQLEXPRESS database. How do I pass each selected part of speech from CheckListBox1 as a variable into the WHERE statement when the user clicks Button1? Do I place this code in the Button1_Click on the .cs page?
2) the table returns the first row and Button1 changes to "Next," which the student then clicks to see the next Latin word. How do I get the Repeater table to show only one row at time until the Next button is clicked? And how do I get the same button to executed two functions (fire off the SELECT statement and then show the next row)? For what it's worth, I'm using the SqlDataReader command, since data will only be retrieved, not modified.
First up i would like to apoligize for these questions that are proable realy easy. I have been put on the spot by my boss and have been told to change all my php to asp.net c so it can go in this new cms i have at work. I have just spent the last 18 hours trying to get this to work and im geting a little desperate.
Ok so my current issue is that i dont know how to add html formating to a result string i pull out of my mysql database. I have my result sheet pulling into a gridview, what i want to do is put some information drawn from each row in the gridview out side of the <Tr> tag. Is this possible? But within the Table Tag second issue is it possiple to feed data into a page and then run a mysql query like i was doing in php.
I have a datalist control that is querying a accessdatasource for information that populates the results based on w/e is typed in a textbox. I can't figure out how to pass the information that is populated in the datalist to another page when a button is clicked (inside the datalist item template).
I was able to peform this in Detailsview with a hyperlink using the following arguments:
DataNavigateUrlFieldsDataNavigateUrlFormatStringBut this seems not to exist in Detailsview. Could someone point me in a direction on how to acomplish this?
I am trying to pass parameters in the hyperlink.

I have 10 hyperlink controls. Depending on which hyperlink is pressed I want to pass a value to the target page. I think the easiest way would be to pass the value using URL of the hyperlink controls. Something like <asp:HyperLink ID="HyperLink1" NavigateUrl="~/News.aspx?id=>. I can pass just a value, but I want to pass a value from a variable.
<asp:HyperLink ID="HyperLink1" runat="server"
I have gridview that lists a column of hyperlinked names. A procedure is passed to get the data for the gridview. I am also pulling an ID to use once the name is clicked. Once clicked the ID is used in another procedure to populate a formview. I am having a problem getting the ID to be associated to each hyperlink name in the column and figuring out how I am going to grab the ID from the asp:hyperlinkfield and then assigning it a variable to use elsewhere. Right now I trying to create a datarow with a new attribute.

I have gotten alot of help lately on my project and think I only have one more issue that I can't think of how to do. What i'd like to do is pass a login name and password from a Login.asp page to all of my other pages. So for instance if I have a successful login, I am taken to the Home.asp page. But i'm not sure how I can pass the LoginID used from Login.asp to the Home page. Ideally i'd like to use this information in the SQL connection strings, and to customize the Home page to show orders assigned to certain people that are logged in.

I have a search page which generates a GridView of results based on the search terms entered by the user. One of the columns in GridView is called a DOI (Document Object Itentifier). This DOI is used to find academic papers through [URL] when a user enters a DOI string. What I would like to do is redirect the user to the relevant webpage when they have selected the DOI in the GridView, however, the url for this page is always different. In the page, I have formatted the form tag like so: [URL] and in my GridView, I have formatted the row that I wish to have hyperlinked like so:
<asp:ButtonField DataTextField="DOI" HeaderText="DOI" CommandName="d"/>
Then, in my C# codebehind, I have the following event which aims to redirect the user to the required page, based on the tag they have selected:
switch (e.CommandName)
{
case "d":
searchResult.Attributes.Add("onchange", "window.open [URL]
break;
}
I don't think this code above makes any difference though as the form tag is already specifying the redirected url, nor do I think this task can be done with a html <table> object, as it only accepts static data, rather than a result set generated from a database, which is what I'm doing. I have also looked at the following post as a guide to this type of problem but, taking account of what it said didn't allow me to solve this problem completely. GridView with DDL and selected value
I am writing what i will call a survey system. The surveys will consist of a series of questions, split into sections. The survey definitions will be stored in a database. The questions can be of various types, that have different input methods and validation (e.g.textbox, numeric textbox, selectlist etc.) I am creating a set of user controls that map to different question types. I would like to completely abstract the survey rendering logic from the, survey definition logic. The way i thought i would do this is to use a dumb rendering control that simply takes a collection of controls and renders them out in a for each loop a super simplified version of what I am doing.
private void RenderControls()
{
foreach (UserControl CurrentControl in this.ControlsToRender)
{
MyPlaceholder.Controls.Add(CurrentControl)
}
}
This works in the sense that the correct controls get added to the place holder,however nothing renders. Presumably this is because it does not have the markup in the asxc file.
If i do something like this
private void RenderControls()
{
foreach (UserControl CurrentControl in this.ControlsToRender)
{
MyPlaceholder.Controls.Add(this.LoadControl("path to ascx file")
}
}
It will create the correct number of controls, but i don't want to instantiate the controls here because i would need to to set various properties based on cconditional logic i want to abstract away from this pure rendering layer.
what i want to do is instantiate the controls else where, set the relevant properties and then simply pass a collection of these into the rendering control to render out.
Is there a way to do this with user controls? Would i have to create custom controls instead?

I have two issues:
Setting Session Variables: I'd like to set some session variables when any menu item is clicked.Dynamic Url: Once the Session variables are set, I'd like to set the url dynamically after the Session variable is set The thing is, I'd like to use the same aspx file for two different menu items, and I'd also like to set some session variables at the time of menu selection. I am aware that I cannot use the same url when I define the url in the web.sitemap file.
How we get dynamic text from database in the hyperlink???

Is there a way to assign/pass/copy a javascript variable to a server side variable in C#? For the sake of argument, let's say that I was able to parse some JSON for variables that I want to store and assign them on the client (ie. var = FirstName and var = 25 and var = someDateTime, etc) .
