my one table consists of fields (id, flying from, flying to). thus i have one drop down for flying from and another drop down for flying to. i'm hoping to cascade them so 2nd drop down values are dependant on the values from 1st drop down. is it possible to do this using a single table? or must i use two tables and link the id's from both? and do i write anyting in the SelectedIndexChange event? the sqldatasource code looks like this:Flying From:
<asp:DropDownList ID="ddlFlyingFrom" runat="server" DataSourceID="SqlDataSource1"
DataTextField="FlyingFrom" DataValueField="Id" AutoPostBack="True" OnSelectedIndexChanged="ddlFlyingFrom_SelectedIndexChanged">

I've this problem, how can I set the default value for drop down list filled with cascading.
I can't catch the event that came after cascading to set the default value and I can't call any control in this function:
"AjaxControlToolkit.CascadingDropDownNameValue[]"
I've passed the Drop down list as a session and the default value in session
When I call the session of "Drop Down List" the session value Is NULL in this function:
"AjaxControlToolkit.CascadingDropDownNameValue[]"

I have 2 dropdownlists, the second (department) cascades from the first (division). I use a jquery script to update the second drop down list. When the user clicks submit, the underlying model is updated, apart from the new value for department. 2 ideas I have for fixing this are; a) Generate a postback. Prefer not to do this because of bad user experience. b) With a JQuery change event, make a call to server side and set a ViewData variable that I can use to update the field in the model later.
However there must be a better way. This is the view;
<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/AdminAccounts.master"

I'm seeking to develop Web page that has multiple Drop Down List (3 controls) bind with my database and these controls support AJAX and access my database using LINQ
e.g, when I select one of the control name : Class, then It should access the database then, display the department in this class in the next Drop Dawn List in the next control - ALL this without PostPacking this page and access the my database using LINQ.

I seem to be having a problem loading a gridview using 2 cascading drop down lists. Before I implemented the Ajax cascading drop down list extenders and I just had regular drop down list the gridview that is supposed to load when users choose the appropriate data from the 2 drop down list appears when the submit button was triggered.
[Code]....
When the button event is triggered it looks for the specific value in the second drop down list and calls a specific stored procedure to load the gridview. Now after implementing the cascading drop down lists the page just posts back - there are no errors whatsoever.

I am currently building a web site and I utilize cascading drop down lists. I am having difficulty clearing two of my drop downs. The application is utilizing Visual Basis. Here is what I found through my research but they are not resetting my drop downs after a post back:
cascadingDropDown1.SelectedValue = Nothing
cascadingDropDown1.SelectedValue = ""
I am stumped on this on and have spent several hours researching this. If anyone has a possible solution I would be greatful.

This may or may not be possible but I'm trying my best to find out, I'm a complete novice when it comes to ASP.At the moment I have drafted a basic html page. This page contains a drop down list and several tables all hidden by javascript and then displayed based on the drop down selection (onchange event)I'm trying to convert this into an asp page so that I can dynamically populate the drop down from a table (this will be a list of names)and then based on the drop down selection (onchange does not necessarily have to be used, could maybe use a submit button) will populate a table below the input box with all the information for that name, in many cases this would be multiple rows.

I am trying to use a cascading drop-down for data entry. However, I'm having problems because I need to set the value of the drop-downs when I load the screen. I use a stored procedure to retrieve the values from my database, and then set the drop downs in my code-behind. Then the web service kicks in and wipes them out. :( How can I set these values and utilize the cascading drop down control?

Basically I want to populate a drop down list with time slots for a user to select. If the time slot is already recorded in the database table I want to skip that one so it doesn't display as a selection in the drop down list.
So my drop down list looks like;
[Code]....
And then I have setup a datasource (even though I may get rid of it to bind in the code behind file)

I have a table with (below) and it popluates a drop down and works properly.
UploadFile -- UploadFileTypeID

Images 1
Spreadsheets 2
Documents 3
Inside the datagrid sort command I want an IF statement. But the IF statement I have now doesn't recoginze whats inside the SQL table ( == "Images").

From my understanding this if (ddl_Upload.SelectedValue == .... Is only recognized if I would have listed -Select, Images etc as List Items for the drop down???

I am creating a cascading drop down control for use with some drop down lists. They are filled using datasets which connect to a MS Access database. The first dataset was no problem however now I need to create the second which contains a where clause using a passed parameter (ie the selected value from the first drop down). In examples I have seen on the web the @ symbol is used eg WHERE fubar = @varname
When I try to execute this in the query builder in VS2008 I get two errors:
Error in WHERE clause near '@'. Unable to parse query text.
Followed by:
Executed SQL Statement: SELECT DISTINCT tbl_frame.frame_name, tbl_product.frame, tbl_product.model
FROM (tbl_product INNER JOIN
tbl_frame ON tbl_product.frame = tbl_frame.frame_id)
WHERE(tbl_product.model = @model)
Error Source: Microsoft JET Database Engine
Error Message: No value given for one or more required parameters.
It never promts for a variable. If I change the query to be something like WHERE tbl_product.model = 7 it works.

I have 3 drop boxes: 1.) Choose Operation 2.) Choose Site 3.) Choose Area. All three of them are linked to an SQL server database which has 3 tables following the same heiarchy of order. I.e. Areas belong to a Site and Sites belong to an operation. And there can only be one operation per site, or one site per area.
First you select an operation, then the page auto postbacks to filter the sites. Then you pick a site and again it autopostbacks to filter the areas. The issue I am having is that when an associated operation has no sites underneight it, and therefore no areas under that, the previous values that were in the boxes are displayed and the user can't click on the boxes anymore. I think this is kind of cheap looking and would like a way to make it so the boxes are clear (i.e. nothin in them). Is there anyway to check if they are going to freeze like that and assign them blank values?

Basically, I'm lookuing to get some performance feedback and peoples thought about speeding up performance of my cascading drop down boxes.
Current;y I'm using a acces.db on the backend to populate the date.
It's just non populating for what I think is fast enough.
Would it be faster if I put the data in a real database? mssql, mysql, etc...
I wouldn't think it was my code, It's not even that many lines.

I am using the AJAX Cascading drop down list but want to add event validation e.g. the compare validators.
As the cascading drop down list requires the page event validation to be disabled what is the best way to do the validation?
Validation Attempt: I have tried to use a custom validator which calls a Javascript function but it doesnt seem to be picking up the control. I get the following error Microsoft JScript runtime error: Object required
function ValidateCostCentCat(source, arguments)
{
var countryList = document.getElementById("ddlCategory");
if (null != countryList)
{
var iValue = countryList.options[countryList.selectedIndex].value;
if (iValue == "Select Category")
{
arguments.IsValid = true;
}
else
{
arguments.IsValid = false;
}
}
}
The mark-up for the custom validator is
<asp:CustomValidator ID="valcustCategory" runat="server" CssClass="error" Display="Dynamic" ValidationGroup="DirectHire" ClientValidationFunction="ValidateCostCentCat"
ErrorMessage="Please select a Cost Centre Category from the drop down list provided.">!</asp:CustomValidator>
