Question

Problem with DropDown / ComboBox selecteditem.text return - list is databound

Asked by: NateDizzle

My problem is:

I have databound a dropdown list to an Access databasem the list is populated with the correct values everytime but when I click the submit button and try to get the selectedItem.Text value from that dropdown list the item always defaults to the first item (rather than the one that was actually selected).  This doesn't happen to non-databound dropdown lists and is really a frustratingly simple problem.

Here's the code upon a page refresh/load:

        cnBATT.ConnectionString = System.Configuration.ConfigurationSettings.AppSettings("connectionString")

        DsCountries1.Clear()

        adptCountries.Fill(DsCountries1)

        Me.basedIn.DataBind()
        Me.hqIn.DataBind()

the data members and such have been set in the properties windowm and seem to work since it is populated properly.

When try to get the item text I use:

       text1.Text = Me.basedIn.SelectedItem.Text


extremely frustrated, Nate-Dizzle

Make sure you Bind your DropDownList when IsPostBack is false in Page_Load event:

by: tusharashahPosted on 2004-11-19 at 07:58:22ID: 12626497

Your code should look like following:
----------------------------------------------------------------------
If Not IsPostBack Then
 cnBATT.ConnectionString = System.Configuration.ConfigurationSettings.AppSettings("connectionString")
 DsCountries1.Clear()
 adptCountries.Fill(DsCountries1)
 Me.basedIn.DataBind()
 Me.hqIn.DataBind()
End If
----------------------------------------------------------------------

If you're binding your DropDownList outside of IsPostBack then when you hit submit it'll get bind again and so the value will be defaulted to the 1st one.

So, I know that the problem is with the page refresh, the selected data is lost during the refresh....not impressed.  Have good method to work around this?

 

by: NateDizzlePosted on 2004-11-19 at 08:08:15ID: 12626619

- it has to be automatic and the first thing the user will click on is the drop down list....I'm going to try a session variable, I really think this is stupid.
