C# - How To Get Multiple Selections From .NET CheckBoxs
Feb 1, 2011
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.
I have 8 checkboxes. when one checkbox is checked i must get the text of checked checkbox with one specific color and if 2 checkboxs are checked i must get the text of checked checkboxs with 2 different colors and so on.
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 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.
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".
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.
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?
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.
My question is I have multiple Checkbox Lists and i want to compare it and Filter Datalist records on Checkbox list checked event.. (I want filtering something like [URL]
using System; using System.Collections.Generic; using System.Linq;
[Code].....
My problem is If first checkbox list is checked and user clicks on second checkbox list then i want to compare both checkboxes and populate result based on both checkboxes.
I have the following simple logic on my buttionclick. Along with this, I need to implement my checkboxlist validation and need to find if more than one boxes are checked.
I attemtpted diffferent things by goggling, nothing worked. I would appriciate your help.
protected void Button1_Click(object sender, EventArgs e) { foreach (ListItem item in CheckBoxList1.Items) { if (item.Selected) { //item.Text and item.Value will give you other properties... if (item.Text == "CSG") { Response.Redirect("page2.aspx"); } if (item.Text == "GGSN") { Response.Redirect("page3.aspx"); } } } }
I have a web form with a gridview control on it. The GridView has a column of check boxes. Before the web form closes I need to check if more than one check box was checked. If more than one check box was checked, then I need to display a popup message box informing the user that only one check box should be checked? I need to check to see if more than one check box was checked, when a "Submit" button on the form is pressed.
How can this be done using Asp.net/C# and Java Script? I know how to iterate through rows of a Grid control so I can do that in the C# code. But how to keep the web form open before I iterate through the rows, I don't know?
I have a datagrid that has 3 checkboxes (checkbox1, checkbox2 and checkbox3). Before i update a record to the database i want to run a validation script on The checkboxes. The function should check that CCheckbox is checked or Unchecked if not checked any all checkboxes sshould fire Validation mssg like "Please check box" any custom validations or javascript validation i am using asp.net with C# very Urgent.
I'm experiencing what seems to be a caching issue with Google Chrome and Safari on my cart page. In the cart there are 2 dropdown lists. When you hit the checkout button after changing the values in the dropdown lists, it commits what's selected in the lists to the database.
It's a little bit hard to explain the unexpected behavior so I will try to write it out step by step with an illustration of my problem.
Lets say the first dropdown list has the values of:
VALUE1 VALUE2 VALUE3
And the second dropdown list has the values of:
DUMBO1 DUMBO2 DUMBO3
I add an item to my cart.
Screen Says: VALUE1, DUMBO1
Database Says: VALUE1, DUMBO1
I hit Checkout.
Database says: VALUE1, DUMBO1 (I can't see the dropdown lists after I hit checkout because i'm not at the cart page)
I hit the back button.
Screen Says: VALUE1, DUMBO1
Database Says: VALUE1, DUMBO1
I drop down the VALUE1 combo and select VALUE2, VALUE2 is selected momentarily and then the site posts back and VALUE1 is re-selected in the drop down list (from being reloaded from the DB)
MOMENTARILY Screen Says: VALUE2, DUMBO1
Database Says: VALUE1, DUMBO1
THEN AFTER POSTBACK FROM DROPDOWNLIST_SELECTIONCHANGED EVENT
Screen Says: VALUE1, DUMBO1
Database Says: VALUE1, DUMBO1
Hit Checkout.
Database Says VALUE1 ,DUMBO1 (I can't see the dropdown lists after I hit checkout because i'm not at the cart page)
Go back.
Screen Says: VALUE2, DUMBO1
Database Says: VALUE1, DUMBO1
So it appears that it's remembering my selection of VALUE2 even though it jumped back to VALUE1 before I checked out.
It seems to be a caching problem, however I've got some no-cache code to prevent caching of that page that works great in firefox and internet explorer but seems to be failing in Chrome and Safari. I'm basically returning in the headers for the cart page: no-cache, no-store, and must-revalidate to attempt to prevent caching, but based on this scenario it seems to be caching the page anyway and not reloading it when I hit the back button.
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)
If InputBookinglength.SelectedValue.ToString = "2" Then Dim paramstring As New StringBuilder If Session("SelectedDates") IsNot Nothing Then Dim newList As List(Of DateTime) = DirectCast(Session("SelectedDates"), List(Of DateTime))

This code works fine when selecting multiple days in one month. But when you switch to display a different month, the previous months selections are lost. how to persist the selections when the visible month changes.
