Web Forms :: Bind BLL To A Checkbox List?
May 4, 2010
I have a checkbox list , a textbox and a search button.
When I click search the data should populate into the checkbox list by using the textbox data as the parameter and I am using a BLL for it.
I have 6 states in my checkbox list and it may have 2 or 3 checked values.
If
dt4.Rows.Count > 0 Then
CheckBoxList1.DataSource = dt4
CheckBoxList1.DataTextField = "MI,IL,IA,WI,IN,OH" 'CheckBoxList1.Items(4).Selected = True
CheckBoxList1.DataBind()

I have a situation where I want to show the selected records out of total records for a product of an employee
1) There is a checkbox list bind to <List> of objects from object datasource (For total items in list)
2) Now I want to check the selected items for a particular record in this list
3) For this purpose I have another list of <List> selected items returned by data access layer (For selected items for that employee )
4) How do I bind the selected objects with the total items list ?
5) In spaghetti coding model it was all too easy just by binding the checkbox list with a sql data source and running a for each on form load

I am trying here to find a simple solution to bind an array of elements to a model using the MVC model binder. If I use the @Html.Checkbox helper now, it will generate me something like this :
[Code]....
I should be ok as it manage the checked in state and not checked in. The problem here is when I try to bind it back to the model (something really simple)
[Code]....
In the controller I try to bind it with the UpdateModel()
[Code]....
When I debug, the chk variable in the model is still null. I tried with IList<string>, bool[], IList<bool> nothing seems to make it. Is there any other way to deal with this else than form.GetValues("chk")[0].Contains("true") ?

I am looking here to find a quick and easy way to bind a list of checkbox list items when the postback occurs in the model. Apparently the common way to do it now seems to do it like this form.GetValues("checkboxList")[0].Contains("true"); It seems painfull and not exactly safe. Is there a way to bind a list of checkbox (that are created with or without an helper in the view) or even an array of data for that matters during the UpdateModel(myViewModel, form.ToValueProvider()); phase which would populate an IList<string> or string[] inside of the model ?

I am absoluetly confused. My web app has a checkbox list that my code is looking to see if the user checked it. Like I said, very simple stuff... Here's the code:
If (chkLaunch.Items(1).Selected) Then
Launch = 1
End If
The odd thing is that when it gets to this bit of code it just moves right past it like it wasn't checked. The same thing happens when I use a single checkbox (rather than a checkbox list). I've tried a bunch of different ways to make the code work but I'm left to the conclusion that I'm just not telling it to do this correctly. Either that or my project is messed up somehow.I say that my project is messed up because when I add an object to the page in Design mode, it doesn't write the source code. So when I save and close, all the modifications are mysteriously gone. This happens on multiple PC's...So, is the checkbox problem just me not doing something correctly or is my web project messed up?

I am trying to pull data from database and populate a gridview. I did it like this:
<asp:CheckBox ID="chkItem" runat="server" Enabled="false" Checked='<%# (DataBinder.Eval(Container.DataItem,"Em").ToString()=="True"?true:false) %>' TabIndex="1" />
I need to have an update on the gridview, so instead if using Eval, I need to use Bind. translate the line above to a bind function?

I have a BLL where in I am getting all the data from a table. Now I want to populate a dropdown with one of the field in this BLL.
ddlstatus1.SelectedValue = dt.Rows(0).Item("StatusCode") and this is not working.
I tried ddlstatus1.SelectedIndex = dt.Rows(0).Item("StatusCode") too but this is throwing an error that string cannot be converted to Integer.
