Design Decisions - CheckBoxList Doesn't Have A SelectedItems Member?

Sep 22, 2010

Whenever I want to get selected items I have to loop through each item and see if it's selected. They even have a SelectedItem (no "s" at the end) member which seems odd for a CheckBoxList. It seems like a logical thing to have, does anyone know why they haven't added it?

DataSource Controls :: CheckBoxList And SqlDataSource To GridView?

Mar 24, 2008

I would like to have my data shown in gridview based on selecting multi-value from the checkboxlist, but it seems that the gridview is only able to response one ticked box in the checkboxlist. i checked with selectcommand by changing to "SELECT * FROM cities WHERE country IN (France,Italy, Germany)" and it shows the data correctly in the gridview, therefore I believe that its either that checkboxlist is not passing multi-values to the sqldatasource, or some code is needed to modify in the sqldatasource to accept multiple values from the checkboxlist. I have no clue what and where to do.

Forms Data Controls :: Value Of Datasource Of Checkboxlist Is Becoming Null

Sep 9, 2010

Page 1: To add a record in to DB. At this page, as per the user requests , few controls will be added to the page from server side code. one of them is checkbox list. and when user is requesting to save data, its going to the DB. Everything is fine upto now.

Page 2: To edit the record which is entered from page no 1. When user requests to edit the record entered at page no 1, i'm redirecting user to this update page, with record id, and generating the required controls to show the values. Now the main problem is :

When page is loading first time, I m creating the required controls and then assigning the values to them to edit. but after that at each postback, the value of datasource of checkboxlist is becoming null, same case is with the label control. but the value of textbox is same, it is not becoming empty at each postback. In code: In code i have created two method to generate controls.

1st is : to create new controls, and to assign values to them

2nd is : to regenerate the controls at each postback, with the same IDs, but not assigning any value here.

I think viewstate will reload the values of respective controls, if IDs are same.

Forms Data Controls :: Checkboxlist To Retrieve Data From Database To Display Results In Gridview?

Jun 23, 2010

I have a page where I will insert all the data into the database. The page where I'm having problems is when I select an item from the checkboxlist it only displays one item. The data which is displayed is only the one that was inserted with one selected item from the checkboxlist. The following code is the page I'm using to try to retrieve the data from the database. I am trying to do is when a user selects the first, second, or third, or fourth item. The corresponding data appears in the gridview. In my current code, the record which has one item selected appears. If the user has more than one selected it does not appear. It comes up as empty. Is there a way I can do it?

Forms Data Controls :: Finding A CheckBoxList Inside GridView's ItemTemplate?

Sep 19, 2009

I have tried and tried to find a CheckBoxList control inside my ItemTemplate in my GridView control. However I have run out of ideas. I'm also having issues of databinding the CheckBoxList control to ItemTemplate as well. I'm doing the DataBind operation on codebehind and it works as it should be. I have only issues by working with CheckBoxList control

My code looks like this:


<asp:GridView ID="grdMyGrid" runat="server" AutoGenerateColumns="false" EmptyDataText="No results found" OnRowDataBound="grdMyGrid_RowDataBound">
<asp:TemplateField HeaderText="Select">
<asp:CheckBoxList ID="chkListMyCheckBoxList" runat="server" />

DataSource Controls :: Reading / Storing Values Of Checkboxlist In SQL (VB)

Sep 22, 2010

I'm trying to store multiple selected checkboxes from a single checkboxlist, but i don't know where to start. Imagine i have three tables: tbl_events, tbl_organisors and tbl_settings and i want to store the organisors of an event. Each event can have multiple organisors, so each organisor should be added as a single row into tbl_settings. I know how to bind tbl_organisors to a checkboxlist, but how do i store the results (meaning: add the rows to tbl_settings) ?

tbl_events: Event_ID (PK) and Event_Name
tbl_organisors: User_ID and user_name.
tbl_settings: Settings_ID (PK), Event_ID and User_ID





Initially all checkboxes will be unchecked, but users must be able to select multiple organisors from the checkboxlist and then store them into the DB by submitting a form. So the query will look something like: INSERT INTO tbl_settings (user_id, event_id) VALUES (@user_id, @event_id). And this is where my head cracks

1) How do i loop through all selected checkboxes and store each value (user_id) in a new row in tbl_settings?
2) After saving, the users reloads the page and the organisors he just selected must be selected by default in the checkboxlist. How?

DataSource Controls :: Building String To Pass Into StoredProcedure From CheckBoxList?

Jul 1, 2010

I have a CheckBoxList that I need to get the values from, concatenate, and pass into a stored procedure in SQL Server 2005 utilizing Visual Basic. Due to the way our data layer is I cannot use a SqlCommand object at this level.

I have no problem getting to the selected values in the CheckBoxList:

Dim selectedValue As New StringBuilder
For i = 0 To cblMethods.Items.Count -1
If cblMethods.Items(i).Selected Then
End If

The problem is that I do not know how to list the values in such a way that my stored procedure will pull data:

SET @MethodNames ='GetWords','GetLetters'
SELECT * FROM TABLE WHERE method IN ( @MethodNames )
I've tried experimenting with apostraphes but cannot make it work:
selectedValue.Append("'''" + cblMethods.Items(i).Text + "''', "

Forms Data Controls :: Retrieving Data From Database To Populate CheckBoxList - C#

Feb 24, 2011

I am somewhat new at C# so forgive me if I have something listed wrong. This is what I got:

I am working on a school project designing a car dealership website. I have an inventory list that allows you to edit any car in the inventory. When you click on the edit button it takes you to the edit page and populates the controls with selections from the database. I have an options table that stores the VehicleID and Option ID. When the page loads it fills all the DropDownLists for the vehicle info with the data and selects the correct item according to the database selection but the CheckBoxList does not select the items that are on the Options table. I checked the query in SSMS and it returns the correct data. I have stepped through the method and it works till the "(currentCheckBox != null) if statement. It doesn't throw any errors but it also doesn't select items when the page renders.

I thought it might have been something with the page life cycle since databound controls don't render until the end but the DropDown's I have fill and selects the correct item according to the database.
