Hi group,

I'm using a listbox and the datasource is a collection of the objects.

My code is:

lisbox.Datasource = collection

it's ok.

I'd like to get the object selected in listbox, but i'm not getting.

How I do it?

Sorry my bad English.

Thanks,

Go,

Sub One() - called onLoad
Dim colVOLEndereco As Collection

colVOLEndereco = objBLLEndereco.fnListar

If colVOLEndereco.Count > 0 Then
lstEnderecos.DataSource = colVOLEndereco
lstEnderecos.DataTextField = "pstrNome"
lstEnderecos.DataValueField = "pstrIDEndereco"
lstEnderecos.DataBind()
end if
End Sub

Sub Two() - Called on postback

Dim colVOLEndereco As Collection

colVOLEndereco = lstEnderecos.SelectedItem

End sub

In sub two, the object selected isn't got. I'd like to put the selected object in colVOLEndereco.

OK?

Is "Sub One()" called during every page load?

You probably only want to call "Sub One()" only on the initial page load, or when the collection has changed.

Trying to use multiple textbox's to filter gridview

How are you "filtering" your gridview? Are you passing parameters to a sql query? Or are you trying to use the dataview filter? Try posting your code if you need help.

do you mean people enter search criteria into the search box and that filters the gridview depending on their criteria?

Just use a select query to populate the grid.
Then in the textbox allow a user to enter criteria then select everything that matches that.
Put the select query on the row create event therefore everytime the gridview is created it checks the query

Hi,

I am filling the dropdown using javascript. I have given the selected index also. But after any server event the filled values are gone. What could be the reason.

Thanks.

The reason is that asp.net uses something called ViewState[^].

If you modify the html on the client via javascrit, that html is gone when the page posts back to the server.

If you are using .net 2.0 or higher. I suggest using AJAX and writing server code to populate the drop down.

Do you understand why it is that if you populate a dropdown with javascript you're going to have to re-populate that list after every postback?
