I have a form with a dynamically generated checklist:
<asp:CheckBoxList ID="cblGames" runat="server" DataSourceID="sqlGames" DataTextField="Game" DataValueField="Id" </asp:CheckBoxList>
<asp:SqlDataSource ID="sqlGames" runat="server" ConnectionString="<%$ ConnectionStrings:Games %>"
SelectCommand="SELECT [Id], [Game], [ShowWaitingList] FROM [Aanbod] WHERE ([ShowWaitingList] = @ShowWaitingList)">
<SelectParameters><asp:Parameter DefaultValue="true" Name="ShowWaitingList" Type="Boolean" /></SelectParameters>
</asp:SqlDataSource>
The following code-behind is supposed to check those boxes that correspond to values stored in a database. It fails and I don't know why.

I have a dropdownlist in EditItemTemplate and InsertItemTemplate which I want it to populate at the runtime while Inserting an item or Editing an item.
I am facing an issue regarding populating a dropdownlist dynamically while in Edit and Insert mode. There are 0 Records in my table and it shows "Empty Data message" in my Listview control. Even the ItemDataBound event does not fire. So I am not able to find the dropdownlist in that listview.
This is my Aspx code which shows only InsertItemTemplate and EditItemTemplate.

am using asp .net 3.5 web forms with VB.I have a masterpage that is populating a treeview from a sql db. When a user clicks on the name in the tree it passes the employee identifier (employee number) to a label on the master page i have hidden. FROM the CONTENT page i am reading the label on the master page and updating the label on the content page to match the label on the master page so i can use the emp number to display info. At least that what i want. However, the content page is not posting back when the label updates of course and its one clikc behind becuase there is no post back. Is there a way to make the page postback when a label changes or a textbox for that matter.Here is how i am updating the label control On the mastepage :
Public Property EmpCode() As [String]
Get
Return Label360.Text

View 1 RepliesI am populating a data bound control DropDownList with file names from a local folder that resides within a ListView control.
I am able to populate as expected, in testing list is generated - all good in that regard.
However once I set to databind by adding SelectedValue='<%# Bind("ImageFile") %>'the following error occurs
ERROR:Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.
This is the aspx file .. no codebehind:

I'm currently building my website and have hit a brick wall. I've not begun coding anything fro this yet as I am unable to get my head around it and not sure where to start.
I've got a database table with a list of town/ county names ( columns are id, town, county).
What I'd like to do is have a template page with set places for town/ county names and then when a particular area is searched for in google/ bing etc my template page with the relevant town/ county name is shown.
I know that's a bit vague so if you have any questions, let me know. One thing I don't want to do is manually create a page for each individual town/ county!
I have a writing a web page that will use several different types of control. The control types will depend on the data being read from a SQL database. The following is my code that decides what control to add to the page:
Select myReader.GetString(1)
Case "DatePicker"
Dim bdpAnswer As BasicFrame.WebControls.BasicDatePicker = New BasicFrame.WebControls.BasicDatePicker()
bdpAnswer.DateFormat = "dd/MM/yyyy"
divAnswerContainer.Controls.Add(bdpAnswer)
Answers.Controls.Add(divAnswerContainer)
Case "DropDownList"
Dim ddlAnswer As DropDownList = New DropDownList()
divAnswerContainer.Controls.Add(ddlAnswer)
Answers.Controls.Add(divAnswerContainer)
Case "RadioButton"
Dim rbAnswer As RadioButton = New RadioButton()
divAnswerContainer.Controls.Add(rbAnswer)
Answers.Controls.Add(divAnswerContainer)
Case "TextBox"
Dim tbAnswer As TextBox = New TextBox()
divAnswerContainer.Controls.Add(tbAnswer)
Answers.Controls.Add(divAnswerContainer)
End Select

View 4 RepliesI have a gridview that is populating from a SQL DB and working fine. However, based upon certain data I find in fields in the SQL table, I want to place a 'n' or a 'y' in extra columns in the gridview that I am assuming need to be templatefields. My thought was I could maybe add 8 template columns and then I could put a 'y' in the appropriate column based upon the data I find the table. For the life of me, I cannot figure out how to do this. I want to do this at rowdatabound time ( i think) but I just cannot find out how to, in my code, put that 'y' in the columns. Is this the right way to do this or do I need to do it another way? How do I get that 'y' in the proper column?

Treeview nodes can be checked. I recreate this control on page load event, but still CheckedNodes is empty if checked nodes were added dynamically (added on demand).
