Hi,
Can someone give me a code look at how I can create a Dynamic Checkbox
within a repeater using VB.NET?

Thanks,
Kevin.

Ok, here's a quick sample:

this is a snippet out of the aspx page:

    <table>
        <asp:Repeater runat="server" ID="myRepeater">
            <ItemTemplate>
                <tr>
                    <td>
                        <asp:CheckBox runat="server" ID="myCheckBox" />
                    </td>
                </tr>
            </ItemTemplate>
        </asp:Repeater>
    </table>
    <asp:Button ID="doPostBack" runat="server" Text="Do PostBack" />

in the code, I show how to bind the checkboxes and then access whatever
their values are on postback:

Protected Sub myRepeater_ItemDataBound(ByVal sender As Object, ByVal e
As System.Web.UI.WebControls.RepeaterItemEventArgs) Handles
myRepeater.ItemDataBound
        If (e.Item.ItemType = ListItemType.Item Or e.Item.ItemType =
ListItemType.AlternatingItem) Then
            Dim myCheckBox As CheckBox =
CType(e.Item.FindControl("myCheckBox"), CheckBox)
            myCheckBox.Checked = CBool(e.Item.DataItem)
        End If
    End Sub

    Public Overrides Sub DataBind()
        Dim checkBoxValues(2) As Boolean
        checkBoxValues(0) = True
        checkBoxValues(1) = False
        checkBoxValues(2) = True
        myRepeater.DataSource = checkBoxValues
        MyBase.DataBind()
    End Sub

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As
System.EventArgs) Handles Me.Load
        If (Not IsPostBack) Then
            DataBind()
        End If
    End Sub

    Protected Sub doPostBack_Click(ByVal sender As Object, ByVal e As
System.EventArgs) Handles doPostBack.Click
        Dim index As Integer
        While (index < myRepeater.Items.Count)
            Dim myCheckBox As CheckBox =
CType(myRepeater.Items(index).FindControl("myCheckBox"), CheckBox)
            Dim output As LiteralControl = New
LiteralControl(String.Format("Item index: {0}; CheckBox Checked:
{1};<br>", index, myCheckBox.Checked.ToString()))
            Page.Controls.Add(output)
            index += 1
        End While
    End Sub

ugh.... sorry, if you want to create the CheckBox programatically, then
all you do is create it in the ItemCreated event handler of the
repeater:

    Protected Sub myRepeater_ItemCreated(ByVal sender As Object, ByVal
e As System.Web.UI.WebControls.RepeaterItemEventArgs) Handles
myRepeater.ItemCreated
        Dim myDynamicCheckBox As CheckBox = New CheckBox()
        myDynamicCheckBox.ID = "myDynamicCheckBox"
        myDynamicCheckBox.Checked = False
        e.Item.Controls.Add(myDynamicCheckBox)
    End Sub

then access it the same way as the previous way, just use the correct
ID (ie. myDynamicCheckBox) in as the parameter of the FindControl call.
