C# Binding Generic LIst<string> to Combo Box

Question

I have a combo box and I want to bind a generic List to it. Can anyone see why the code below won't work? The binding source has data in it but it won't fill the combo box data source.

FillCbxProject(DownloadData Down)
{
  BindingSource bindingSource = new BindingSource();
  bindingSource.DataSource = Down.ProjectList;
  cbxProjectd.DataSource = bindingSource;
}

On a side note is it bad to pass around an instance of a class?

Thanks!

Answer 1

You need to call the Bind method:

cbxProjectd.DataBind();

If this is for winforms then you need to make sure what you have is being called, the following works:

BindingSource bs = new BindingSource();
bs.DataSource = new List<string> { "test1", "test2" };
comboBox1.DataSource = bs;

Although you can set the ComboBox's DataSource directly with the list.

I have just posted a code for something similar to that, check the link below
