I am trying to use a variable from the code-behind page in a sqlDataSource WHERE statement. I am using Membership.GetUser().ProviderUserKey to obtain the UserId of the logged in user and I would like to only show record that have this UserId as a foreign key. How can I write the SQL for this?
Here is what I have so far:
SQL Query:
SelectCommand="SELECT [UserID], [CarID], [Make], [Model], [Year] FROM [Vehicle]"
Code-Behind
String user2 = ((Guid)Membership.GetUser().ProviderUserKey).ToString();
And I want to add WHERE UserID = user2 to the SQL Query.

I have a Gridview which I'm populating through code behind. A couple of columns of the gridview I've set up to be drop down lists. What I want, is that when I run my Insert query, it takes the drop down list selected value, finds the appropriate ID and uses that ID as part of the insert query.
Below is my select and insert query.

Trying to use a dropdownlist to query a database so that it will return all values except 1 (or more in future versions).
For example, assume you had a simple table name "MYFRIENDS" which has two fields named "GROUP" and "NAME" with the following records:
Group
Name
A
John
B
Jane
C
Tony
D
Sue
What I want to do is create a DropDownList that has only 2 list items related to the "GROUP" field. The first list item should return records from the database related to Group A only. Then, the second list item should return all other records EXCLUDING those belonging to Group A.
The drop down list should look something like this (I've put a question mark where I don't know what to do):
[Code]....
After the selection is chosen in the above drop down list, it should query the database and return the desired result. I'm using an AccessDataSource with select parameters. Here's a sample of what that looks like:
[Code]....
Things I've tried that didn't work:
I tried using "Not A" as the the 2nd list item's value. I was thinking p1 would be replaced with the value "Not A" and the query would read "WHERE GROUP LIKE Not A". But, the query syntax "Like Not" is technically wrong. I tried changing the Where Clause to "WHERE GROUP p1" and then replaced the list item's value to "LIKE A" and the second to "NOT LIKE A". Again, I was thinking p1 would be replaced to read "WHERE GROUP LIKE A" and "WHERE GROUP NOT LIKE A". I also tried changing the "SelectCommand" itself so that after the dropdownlist changed, it would first change the selectcommand first and then run the query.
Why the first 2 items didn't work became somewhat obvious to me after thinking about it for a little while. However, I would think the 3rd one would/should work... as long as you have the sequence of events correct which up to this point I haven't been able to figure out.

In the first Page_Load, I am activating a javascript function to make an ImageButton change between 2 images with an interval.
This works fine.
Now when pressing this imagebutton, the Page_Load event will fire the second time and all this is happening in an updatepanel which means a partial postback.
The question is how to execute the javascript function stopbk() in the Page_Load event in this scenario as I cant just put it in the "Onload". How can I make that work?

View 2 RepliesI have a webpage that displays the results of a query on a table. The resulting list is sorted by town:
New York
Hyatt Regency Waldorf Astoria
Paris
Hotel du Louvre Hotel Le Meurice
I've been asked to add to this list another sublist of nearby hotels. The intended result is:
New York
Hyatt Regency Waldorf Astoria nearby hotels:
hotel 1 hotel 2
Paris
Hotel du Louvre Hotel Le Meurice nearby hotels:
hotel 3 hotel 4
I've got a TableAdapter set up in VS2010 so that I can query the table for nearby hotels with "@town" as the parameter. So at the end of each list of hotels in a town, I need to display the results of this query.
If the query turns up no records (no nearby hotels), I don't want to display anything. If it turns up 1 or more records, I want to display the list of nearby hotels.
I am trying to set up a conditional "if" statement that checks to see if any records returned but am getting an error when I try to build:

I have a checkbox on my page that must be ticked and to validate it I am using a custom method as below. The problem is that I now put the checkbox and method within a Create User Wizard custom tempalte and when I submit the form it does not activate the validation check. If I put a normal button on the page outside the tempalte it works. Not sure If I a missing something. Perhaps I can activate it in Created User Event handler in code behind. All Button in my create user Event.
<asp:Button
ID="StepNextButton"
runat="server"
CommandName="MoveNext"
OnClientClick="ShowMP();"
align="middle"
CausesValidation="True"
Text="Submit
my Profile"
/>
aspx
<asp:CheckBox ID="Terms" runat="server" />
<asp:CustomValidator ID="valTandCs" ClientValidationFunction="ValidateTandCs" runat="server" ErrorMessage="Please accept Terms and Conditions before submitting."></asp:CustomValidator>
Javascript
<script language="javascript" type="text/javascript">
function ValidateTandCs(source, args)

args.IsValid = document.getElementById('<%= Terms.ClientID %>').checked;

In MS Access there is a great method call 'dropdown', you set the focus to the control, mycontrol.setfocus and then call mycontrol.dropdown, really useful when using cascading dropdowns.
Is there a similar method in asp.net or how would I get the dropdownlist to dropdown through code?

View 3 RepliesI have two DropDownLists; DropDownListStart displays the hours 09:00 - 19:00 and DropDownListStop displays 10:00 - 20:00. When the user chooses one of the hours in DropDownListStart I want the program to adjust what's shown in DropDownListStop so that the first hour shown is one hour after the hour chosen in DropDownListStart. How can I do that in code behind (c#)? An example: if the user choses 13:00 in DropDownListStart I want DropDownListStop to display only 14:00, 15:00, 16:00, 17:00, 18:00, 19:00, 20:00.
