DropDownList SelectedIndexChanged window.showModalDialog

P: n/a
I am displaying an ASP.Net generated form in a popup opened with
window.showModalDialog.

The form contains DropDownList controls. The first ddl is populated via
databinding to a datatable, has its AutoPostBack set to true and has its
SelectedIndexChanged event being handled in codebehind. The event fires as
it should populating two more ddls.

The problem is, the two ddls appear empty. I have used a javascript alert
to look at the innerHTML of the body and the SELECT tags have the correct
OPTION tags contained within them, but they display as empty.

A funny thing is, if I set a break point in the SelectedIndexChanged event
and step through the code, they will display properly. I have examined they
HTML generated when I break and when I don't, and it is the same for both.

This is strange, can anyone help me?

Thank you,
Scott Lee

Hi Scott,

You didn't show us the code that is causing the problem, so I can only guess
at what may be causing this. Make sure that the rest of the HTML is
well-formed. Missing closing tags could be preventing the page from rendering
properly.

If you can post code that reproduces the problem, that would help a lot.

The problem is associated with using this form in a popup opened via
window.showModalDialog. The HTML is well formed and all OPTIONS appear in
the SELECT, they just don't display. The ddls are filled via this code:
-----------------------------
Dim sb As New System.Text.StringBuilder(128)

Dim wsOO As New wsOwnerOperator.OwnerOperator

Dim drDriver As wsOwnerOperator.tdsOwnerOperators.DriversRow

Dim drTractor As wsOwnerOperator.tdsOwnerOperators.OwnerOperatorTra ctorsRow

Dim li As System.Web.UI.WebControls.ListItem

Dim i As Integer

'clear the ddl

ddlTractor.Items.Clear()

ddlDriver.Items.Clear()

'get the dataset

_tdsOwnerOperators1 = wsOO.GetOwnerOperatorsFull

_tdsOwnerOperators1.EnforceConstraints = False

'add a column to allow display of the Driver's full name in the ddl

If _tdsOwnerOperators1.Drivers.Columns("FullName") Is Nothing Then

Dim col As New System.Data.DataColumn("FullName")

col.Expression = "LastName + ', ' + FirstName"

_tdsOwnerOperators1.Drivers.Columns.Add(col)

End If

'add a column to allow display of the tractor's make, model, year, and
license# in the ddl

If _tdsOwnerOperators1.OwnerOperatorTractors.Columns( "Description") Is
Nothing Then

Dim col As New System.Data.DataColumn("Description")

col.Expression = "TruckNumber + ' - ' + Year + ' ' + Make + ' ' + Model + '
' + Color"

_tdsOwnerOperators1.OwnerOperatorTractors.Columns. Add(col)

End If

_tdsOwnerOperators1.OwnerOperatorTractors.DefaultV iew.RowFilter =
"OwnerOperatorID = " & ddlOwnerOperator.SelectedValue & "OR
OwnerOperatorTractorID = -1"

li = New System.Web.UI.WebControls.ListItem("Please Choose One", CStr(-1))

ddlTractor.Items.Add(li)

ddlDriver.Items.Add(li)

For i = 0 To (_tdsOwnerOperators1.OwnerOperatorTractors.Default View.Count -
1)

li = New
System.Web.UI.WebControls.ListItem(CStr(_tdsOwnerO perators1.OwnerOperatorTra
ctors.DefaultView(i).Item("Description")),
CStr(_tdsOwnerOperators1.OwnerOperatorTractors.Def aultView(i).Item("OwnerOpe
ratorTractorID")))

ddlTractor.Items.Add(li)

Next

_tdsOwnerOperators1.Drivers.DefaultView.RowFilter = "OwnerOperatorID = " &
ddlOwnerOperator.SelectedValue & "OR OwnerOperatorID = -1"

For i = 0 To (_tdsOwnerOperators1.Drivers.DefaultView.Count - 1)

li = New
System.Web.UI.WebControls.ListItem(CStr(_tdsOwnerO perators1.Drivers.DefaultV
iew(i).Item("FullName")),
CStr(_tdsOwnerOperators1.Drivers.DefaultView(i).It em("DriverID")))

ddlDriver.Items.Add(li)

Next

End Sub

------------------------------------------------------

If I set a break point in this code and setp through it, voila, it displays.
If I don't it does not. The form sets SmartNavigation to true. If I
comment that out (causing the postback's response to the event to open in
another browser window), it works. I would assume that it is an IE
6.0.2800.1106 problem, except that it works if I set a break point in the
code.

I do the same thing in other forms throughout the site and have not
experienced this problem before.

As I cannot "view source" on a window opened via the showModalDialog method,
and I cannot copy text from an alert, I do not know how I can get you the
HTML that is generated from the ASPX.

Hi Scott,

It sounds like SmartNavigation is causing a client-side syntax error in the
page but you're not see it in the modal form.

What happens if you launch the page as a regular Web page, not using
showModalDialog ? Can you see anything funny in the source?

Scott:

The URL property on a dialog is read-only. You cant change it once you set
it, even if it is the same page (ie posting back to self). I figured this
out recently and was a pain in the butt.

Try putting the HTML inside the dialog inside of an IFrame. Thats what I
did and it fixed the problem.

Best of luck!

P: n/a
A coworker of mine just suggested that I add a <base target=_self> tag to
the HEAD section and not use SmartNavigation. That worked also.

Thank you for your time and concern,

Scott:

The URL property on a dialog is read-only. You cant change it once you set it, even if it is the same page (ie posting back to self). I figured this
out recently and was a pain in the butt.

Try putting the HTML inside the dialog inside of an IFrame. Thats what I
did and it fixed the problem.

Best of luck!
