I am trying to add an attribute to a dropdownlist control to store a value returned for the database. This value is need to get a code once a selection is made on the dropdownlist;
I have tried the following:
ddlStatus.DataTextField = dsValues.Tables(0).Columns("Description").ToString ()
ddlStatus.DataValueField = dsValues.Tables(0).Columns("CategoryCode").ToStrin g()
ddlStatus.Attributes.Add("SysCode", dsValues.Tables(0).Columns("SystemCode").ToString( ))

Let's say I have a DropDownList of product categories and a ListView of products based on the category selection in the DropDownList. When a user visits the page, there is a possibility of conconrency issue as new product belonging to a new category may be added to the inventory as the user is browsing.When the user selects a different category to view(a SelectedIndexChanged event) and causes a postback, I want the DropDownList to update the list of categories to include the new category being concurrently added and at the same time still able to make a change of selected index.

I was just wondering if it is possible to apply an attribute to a property within a business object (MyBusinessObject) such that after the DataSource of a grid is set to a List(Of MyBusinessObject), the visible property of the column will automatically be false. For example:
myGrid.DataSource = New List(Of MyBusinessObject)
Public Class MyBusinessObject

I have found a couple of examples on the internet to do this but really struggling to get it working in VB. (Tried a converter but had mixed results) I need the selection options of a Dropdownlist to be populated based upon the differing values in the first dropdown list.
Can anyone help with a releativley simple example in VB? Not fussed if the values are "hard coded" in the script. Or a SQL bit that pulls the data from a table

I have a DataAccessLayer that returns a datatable. The business layer calling it also returns a type datatable.In my form, I call the business layer as a datasource of my gridview and then I binded it.
This codes are working in C# but I have problems when I converted it to VB.NET. During databind it displays the error: Data source is an invalid type. It must be either an IListSource, IEnumerable, or IDataSource.
Can i not bind a datatable in my gridview in vb.net? What do you think is the problem?

I have a DataGridView that is inside a TabControl. After I bind the DataGridView with data, the first row is selected. How do I prevent this from happening. I tried DataGridView.ClearSelection and DataGridView.Rows(0).Selected = false. Neither of these options work. I think it has something to do with the tab control not being completely drawn before I call the methods. If I run this code from a button it works.

My dropdownlist is set to databine like this...
dt = dal.FillDataTable(SqlConnectionString, "SELECT SQL Query Statement")
dropdownlist1.datasource = dt
dropdownlist1.datatextfield = dt.columns.item(0).tostring
dropdownlist1.databind()
This is turn populates my dropdownlist, when a user selects a value, it is then populated to the remaining textboxes on the remaining forms with a session call...
dropdownlist2.add(ctype(session.item("valOne"), String))
Through this session it populates the one value, is it possible to display the selected value but also include all other dropdownlist items in case they want to change thier selection?

I would like my website to allow users to download files which are stored as blobs on the database, the database holds fileID fileName and theFile. I have a grid view with two columns, fileName and a template column, which is databound to fileID and has a linkbutton. When the link is clicked it calls to a function which downloads the file. The function needs the fileID to download the file, how do I get the fileID bound to the selected linkbutton.

I have a GridView on an ASP.NET page that I'm trying to bind to an object data source that I've set up to map to a vb object I made which accesses the DB. When I run the page, though, the gridview comes up empty.
The ObjectDataSource is definitely returning data. The paging parameters are making it to the underlying object. All the way until I get to the DataBind() call everything seems fine. But the grid comes up empty. Funny thing is, if I use the method that returns all records in the DB, the grid populates just fine. Only when I try to implement custom paging does display no records. I've tried using the wizards, I've tried diagrammatically setting it up and run time. No matter what I do I can't get paged data to display in the grid.
oDatasource = New ObjectDataSource()
oDatasource.EnablePaging = True
oDatasource.TypeName = "tblMessage"
oDatasource.SelectMethod = "GetTblMessageSubset"

I have an AccessDataSource TestSummaryADS. I can easily view the results in a GridView or DropDownList by setting its DataSourceID property.
How do I bind a value from the results TestSummaryADS to the text of a label?
I'm just trying to populate labels on my page with results from the DB entry.
C# or VB.NET answers okay.

I am databinding my gridview in VB code behind. Because of this I know I can not refer to the NewValues when text is entered into one of the edit boxes. I need to retrieve the value of a column in the RowUpdating event.I have tried to do this in a multide of ways, but each of my changes ends up breaking something else.None of these three methods is working....
Dim DT34 As String = DirectCast(GridView4.Rows.FindControl("Textbox1"), TextBox).Text
Dim TB1 As Label = GridView4.Rows(e.NewEditIndex).Cells(0).FindControl("Label1")
Dim tb1 As TextBox = GridView4.Rows(e.RowIndex).Cells(0).FindControl("TextBox1")
Dim IDVal As String = tb1.Text
In the following code, I am believe it is finding the control but it is not returning the value that was entered into the textbox.
Dim tb As TextBox = DirectCast(GRD4.Rows(index1).FindControl("TextBox1"), TextBox)
updateDescription = tb.Text
My field has been converted to a Template field in the Gridview instead of Boundfield.
