Is there one method for getting a value in a comboxbox (DropDownStyle set to DropDown) regardless of whether the user entered or selected a value.  My combobox is initially populated with a datatable and has a Value and Display member.  Since a user can enter thier own value, it would not have a ValueMember, therefore SelectedValue fails.  It seems I may have to test the SelectedValue and the Text properties for both validation and saving the data.  I was hoping there would be an easier way.

Also, I just noticed that I may not be able to use the DataBinding properties from my bindingsource because if I bind using the SelectedValue, if the value isn't in the list then it doesn't show up.  If I use the Text, everything works but I can't leave the control, let alone close the form.  It seems to get hung.

i am trying to publish my application and I am receiving the following error message:

Cannot make this application an online application because the previous version is installed. To install this application uninstall the previous version, or mark this application as installed.

How can i mark this one as installed

Thanks,

Hi all,

I was wondering if its possible to redistribute certain dlls in the same directory as my program and for it to still work.

If this is possible, then how would I find out which ones are needed

Thanks Wilk06

I'm using VS2005/C#

I have a treeview, and I'm using SQL to pump date to it (treenodes), I have a view pages that have a Response.Redirect, problem is when I click on it it dosnt remember the highlighted node, or expand to the correct node.

I've tried using the code below to view data from a select query in a datagridview control (along with several other methods) with no success. It is slightly adapted from a BOL example. The bindingnavigator appears to be reading the bindingsource ok (shows correct number of records) however, the datagridview remains blank.

Private Sub GetData(ByVal selectCommand As String, ByVal connectionString As String)

Dim VwTblDataAdapter As SqlDataAdapter

Try

' Create a new data adapter based on the specified query.

VwTblDataAdapter = New SqlDataAdapter(selectCommand, connectionString)

' Create a command builder to generate SQL update, insert, and

' delete commands based on selectCommand. These are used to

' update the database.

Dim commandBuilder As New SqlCommandBuilder(VwTblDataAdapter)

' Populate a new data table and bind it to the BindingSource.

Dim table As New DataTable()

Me.BindingSource2.DataSource = table

' Resize the DataGridView columns to fit the newly loaded content.

Me.DataGridView2.AutoResizeColumns( _

Catch ex As SqlException

MessageBox.Show("To run this example, replace the value of the " + _

"connectionString variable with a connection string that is " + _

"valid for your system.")

End Try

End Sub

I have datagrid wih two colums, Name & Role. I just want to the show the datagrid that there role is A. In that
column I have a ddl_role list.

if(dgUsersAd.Columns.Equals("A"))
//if(dgUsersAd.Columns[1].InitializeCell)
{
daUsers.Fill(dsUsers1.users);
dgUsersAd.DataBind();
}
else
{ lbl_mes.Text = "NO Admin Users".ToString(); }

I tried it this way..but it is not working.

I am an old C/C++ programmer that is trying to learn C# and .net. I need to take text from a .txt file and display it on a form in graphics. I eventually need to save the image to a .jpg file.

I created a picturebox (is this the right object to use ) on the main form, opened the .txt file and read in one line at a time. Now I need to put each line of the text into the picturebox area in graphics mode to display it on the screen in the same order as the text in the file.

Any suggestions

Thank you
