AJAX :: Multiple Selections In A Dropdown Control ?
Jul 23, 2010
I have a requirement to allow users select multiple "Agencies" and populate the "Types" based on that selection. Cascading Drop down would have been a great fit if there is no mutliple selection involved. I am wondering if I could use a popup dropdown with chekcboxes. However, these checkboxes need to be populated dynamically by a web service. I am not very familiar with AJAX toolkit and what control would work best in this case.

Does anyone know if it is possible to have Cascading DropDown Lists which are based on the selected value of more than a single list. Example - I have four tables in a database as follows:
Product
PartA
PartB
PartC
The items in Product are made up by one record from each of the other three tables (PartA + PartB + PartC = Product). What I wish to do is have 3 Cascading DropDown lists which refer to the three individual parts which can be used to select items fromt he Product table.
The first two work no problem but when it comes to the third the list is condition on only items which have the selects of both the first two lists.

I have a dropdown with names of project managers and a checkboxlist with names of team members. What I want to do is write the IDs of selections made from the dropdown and checkboxlist to the DB. I am using the following code, but only IDs from the checkboxlist are stored in the table. What can I do to store the ID from the dropdown simultaneously? Thanks for your help.
for (int i = 0; i < project_members.Items.Count; i++)
{
if (project_members.Items[i].Selected)
[code]...

I am using the cascading dropdownlist controls from the Ajax toolkit. I have everything working perfectly and all of my select changes work. I have 3 related select boxes that all work great for single item select. What I need is for my last dropdownlist to allow for the selection of multiple items. I have tried adding the 'multiple' attribute to the final dropdown list and it allows the selection of multiple items but I cannot get the items when I post back, just a single item.

I have a FormView that is used to insert records into a table. It is set to a default mode of insert. When I click a LinkButton it makes the FormView visible and populates a DropDown List control via code. When I click the Insert button, it inserts the record into the table but then the DropDown List selections disappear. How can I keep the selections so that I only have to fill it once?

I have a drop down that lists all our 40+ locations.. I then have a list box with all our locations as well. The client is presented with the question which locations have you worked at before. If they pick say 3 locations, i need to remove or disable those 3 from the drop down. I have other code for creating a drop down, but not sure where to go with this.
Here is my code for the controls and code behind:

This seems like it should be prettty easy - but I just can't get it to work!I have an enum in my model, which I want to display as a list of checkboxes. The user can select multiple checkboxes, and I want to save this in the database.
So the enum is like so (approx 20 elements unabridged):
public enum ReferrerType
{
[Description("No Data")]
NoData = 9999,[code]....
And it doesn't work! I guess I'm missing something obvious, but I can't work out what. There are no errors - just an empty database table where referrers should be.

How do I handle selection of multiple items with autocomplete? The objects I return from my JSON web service contain an ID and a Label - the ID is the ID of the entity in the database, and the Label is some text to display for the user.
At the moment, when I select an item in the autocomplete dropdown, the value of the item's ID is stored in a hidden field, and the label is displayed. When I remove the label, I clear the ID of the hidden field - this is done by adding an anchor element to the DOM that handles this.
Now, I want to have multiple selections. I want to be able to enter some text, get an autocomplete dropdown, select an item and some other options, then be able to click an 'Add New' button or the likes to be able to select another instance.
For example, I'd type in a person's name and get an autocomplete selection. I'd select a person, and then enter their age, and click 'Add'. The person's id, name, and age will be stored somewhere so that I can retrieve it on the server side when I post back.
I'm not quite sure how to do it? I'm thinking of a hidden field - I assume that many hidden fields of the same name/id turn up on the server side as an array, which I can then use. But I haven't tried this yet in ASP.NET.

I am trying to populate the value(s) of a listbox that has multiple selections:
Assignment Preference:<br />
<asp:ListBox ID="assignmentPreferenceList" SelectionMode="Multiple" runat="server">
<asp:ListItem Value="">None</asp:ListItem>
<asp:ListItem Value="CONTRACTING">CONTRACTING</asp:ListItem>
<asp:ListItem Value="DIRECT HIRE">DIRECT HIRE</asp:ListItem>
<asp:ListItem Value="CONTRACTING-DIRECT HIRE">CONTRACTING-DIRECT HIRE</asp:ListItem>
</asp:ListBox>
I am using a datareader in code behind to "loop" through the values:
string sql4 = "Select * from assignmentPref where tID=" + (dr["id"].ToString());
SqlCommand comm4 = new SqlCommand(sql4, con3);
SqlDataReader dr4 = comm4.ExecuteReader();
while (dr4.Read())
{
assignmentPreferenceList.SelectedValue = (dr["assignmentPref"].ToString());
}
Works great with 1 assignment preference but with 2 or 3 it craps out.

I have a web form that when completed sends an e-mail with the data from the form. I have a list box that permits muptiple selections and it post to the email with the following code.
sb.Append("<br />Products of Interest:....");
for(int i = 0; i < ListBox2.Items.Count;i++)
{
if(ListBox2.Items[i].Selected)
sb.Append(ListBox2.Items[i].Text);
}
It works fine except that when multiple tiems are selected, they run together on the form. Instead of "Beds Dressers Tables", I get "BedsDressersTables".

I have the followingh scenario where I have a radgrid and inside it, I have a template column containing a check box:
[code]....
However, I only really want the user to be able to select one checkbox at a time.
Therefore, how to I go about ensuring that the any previous 'checks' are removed or stopping multiple checking altogether?

New at SQL and ASP.NET C#, bear with me. I have a form to insert into mulitple tables of a sql db. The form includes two listbox's, categoryIDlistbox and subcategoryIDlistbox, both with the ability to select multiple choices. Idea is that there is one record for the user created (Table1) and then that user can have multiple categories and subcategories assign to him/her in Table2
Table1:
userID
fname
lname
etc...
Table2
userID
categoryID
subcategoryID
If I understand correctly I need to use an array to take the multiple listbox items and save them to the tables. Not sure where the array goes in my code behind page to process the listbox and loop for muliplte selections. Here's my current code behind, where do I place the listbox array?

Using SQL Server 2008, C#, .Net 3.5
I have two tables - Reports, Usage
Report table:
RId
RName
RGroup
Usage table:
UId
UUser
What I want to do is make a page that will list all the reports in the Reports table and have a checkbox next to each name. A user can check each report they use and when they click "submit" it will insert each ReportID into the Usage table.I'm guessing that I should use a GridView to display all the Reports?How would I make it so that the "submit" button would insert each "checked" record into the Usage table?

I'm storing details about clothing in a database, and I need to save multiple entries for colour. For example, a user selects a top, and then needs to select the colours red, black, white and blue from say a group of tick boxes. How should I store this infomation, and what web controls would I use to help the user make there selection?

the form has 15 items to choose with radio buttons, any number can be selected. I would like to process them as a 'group' so I can do something like loop thru them, checking if each one has been selected to build a list and also be saving them to a table row, etc but it seems all the designations as a list or group make it mutually exclusive. just looking for better coding than checking them with an if statement or similar so the question is if there is some way to designate the radio buttons as a group but no force the group to be mutually exclusive

I have a list box that allows for multiple selections (holding down the control key) the selection quantity is basically unlimited, but realistically should never be more than 50 to 100 items from the listing of about 3000 items.
I need to collect the list of selected items from the drop down list and retrieve each of their full records from the item master and populate a gridview.

I could really use some building the SQL statement to select the choosen record data. I think I have the selection list worked out by populating an array but I am not clear on how to build the SQL query.

DropdownList 1 : It is the parent dropdown for dropdownlist 2. Dropdownlist 2 is filtered as soon as any value is selected from dropdownlist 1.
DropownList 2: It contains numeric data which is filtered on the basis of dropdownlist 1 selection.
DropdownList 3: It contains the units for the numeric data displayed in dropdownlist 2. If the user selects some unit in dropdownlist 3, the data in dropdownlist 2 should be filtered accordingly.
let me know whether it is possible to have 2 parents controlling the data in a single cascading dropdown?

I am using AJAX ComboBox control (or I can use simple ASP.NET DropDown Control it does not matter) in my form. What I do is, I bind combo box control to my database and retrieve client names:
[Code]....
But here is the problem. I want First and Last names to go into separate TextBox controls (txtFirstName and txtLastName). Now it inserts Last Name and Firts Name in txtLastName control. At the same time I would really like to keep LastName + FirstName together in Combo Box.
