I am fairly new to ASP.NET C#, I have a vehicle table which stores basic info about the vehicle, then a vehicle options table that stores the options available on the table.

I have a checkboxlist control on my form and I am populating the list items from the database. I am trying to loop thru the items to determine which ones the user has selected. After determining which ones are selected I need to add rows for each item selected to the vehicle options table.

Oct 24, 2010

I wanted to know if it is possible to pass multiple selected values from Checkboxlist to SQL table so each selections goes into separate row in the table.

Web Forms :: Insert Checkboxlist Selected Values Into Sql Table Using Createuser Wizard

Sep 20, 2010

I am using CreateUserWizard control where I collect personal information from the user on the first step (ie. name, address, tel, mobile etc) then on the second step I collect information for membership service (ie. user name, password, email etc). When user clicks Create button, information is sent to two different tables in the same database. Everything works fine but one.

In the first step where I collect personal information, I also collect details about Interest which is a CheckBoxList (CheckBoxList is getting values from Interests table: 1-White, 2-Green, 3-Brown, 4-Maroon, 5-Yellow).

What I want to do is, when client selects his itnerest categories and clicks Create button, to send selected values from CheckBoxList into the third table called Categories. I want values to be registered into the CatCode column in Interests table as comma delimited. For example: if client selected "White", "Green" and "Yellow", appropriate values for those interests (such as 1, 3, 5) to be registered under Categories table CatCode column (like: 1,3,5).

Following is my code:

C# - Checking If Gridview Has A Selected Item?

Aug 30, 2010

I have a grideview and 2 buttons. I need to only show the buttons when the gridview has a selected item. My code looks like this:

protected void Page_Load(object sender, EventArgs e)
btactivate.Visible = false;
btdeactivate.Visible = false;
//Show Activate and Deactivate Buttons only if an item in the gridview is selected
if (GridView1.SelectedIndex != -1)
btactivate.Visible = true;
btdeactivate.Visible = true;
btactivate.Visible = false;
btdeactivate.Visible = false;

But the problem I have now is that only when I select the second time a item in the gridview the buttons show up. I need to have the the buttons show when I select the first time. I have tried changing the selected index to "-0" but that shows the buttons all the time (even when I dont have something selected).

Web Forms :: CheckBoxList Order Of Selected Items?

I have a checkboxlist that gets data from my database and displays a list of items.

Item 1
Item 2
Item 3

I know how to get the chosen items, but i'm not sure how to get them in the order that they were chosen. This is my code to get the selected items.


So if I choose Item 3, Item 2, and then Item 1, when I display them on a label, the order is always Item 1, Items 2, Item 3. How can i preserve the order of the chosen items?

Web Forms :: Display Selected Criteria From Checkboxlist?

Mar 15, 2011

When a user selects an item from an asp:checkboxlist, I would like for that item to show up in a "Selected: " area. Here is a link to a webpage [URL] that has the same functionality that I'd like for my page. Each time an item is selected, it shows up in the (for example, from the included link) "Selected Catagories" area (or is removed when an item is deselected). I would like this functionality to work for each one of my checkboxlists (I have three separate checkboxlists). The users can select as many (possibly all), or as few, items from each checkboxlist as they want.

C# - Return Selected Items From Checkboxlist Control?

Sep 22, 2010

I am trying to return in a string the selected items from a dynamically bound checkbox list control with no luck. In my code behind file I am conencting to a class called users and building a datatable. I then bind the data table to the cblist control

private void populateUserList() //called on page load
SubmitOptions mySubmission = new SubmitOptions(juris, rptType, tmplName);
if (mySubmission.Users.Count == 0)


The list populates fine and all I want to do is return in a string all selected users from the checkbox list control.

As I said if I hard code the item values into the control the above code works and I can see the selected items in the string however removing the itemslist tags and switching over to a binding nothign happens. The above method counts the entire number of returns but nothing selected is ever returned.
