That procedure is execute the first time because the page is loaded,
and the data is bind to the formview, but when you are using javascript
calls, no postback is execute, so, you do have a way to solve it.
create a div control on your page, and on LoadData procedure wich will
return a string you create a new FormView, set his properties as you
want, execute the DataBind procedure and through the RenderControl
method you get the html generated by the formview send it to the client
and assign it to the innerHTML propertie of the div.
I don't use Visual Basic, I use C#, but I'll try to write here how you
should do it.
<script type="text/javascript">
function ChangeData()
{
test.LoadData(document.getElementById("txt").value,
ChangeData_callback);
}
function ChangeData_callback(res)
{
document.getElementById("mydiv").innetHTML = res.value;
}
</script>
<div id="mydiv"></div>
the behind code :
dim strDeptCode as string
.....................
.....................
<AjaxMethod()> _
Public Function LoadData(byVal DeptCode as string) As String
Dim fv As FormView = New FormView()
'Set fv properties and the page you want to show
strDeptCode = DeptCode
fv.DataBind()
Dim sb As StringBuilder = New StringBuilder()
Dim sw As IO.StringWriter = New IO.StringWriter(sb)
Dim tw As HtmlTextWriter = New HtmlTextWriter(sw)
fv.RenderControl(tw)
Return sb.ToString()
End Sub
Protected Sub fv_DataBinding(ByVal sender As Object, ByVal e As
System.EventArgs) Handles fv.DataBinding
If strDeptCode = "" Then
dsDept.SelectParameters("DeptCode").DefaultValue = "all"
Else
dsDept.SelectParameters("DeptCode").DefaultValue =
strDeptCode
End If
End Sub
you are not suppose to have an asp:FormView on your page, but generate
it dinamically, using what I wrote here, otherwise you could only send
the data that will be visible from server to client and generate with
this data your own html code for a FormView on the cliente , using
javascript, actually that's how I do it.
I hope it could help you.
good luck, if any doubt, ask again.
