Auto complete Box

Add auto complete box for datagrid in C#

As we learned how to add an auto complete option for TextBox control in C#, we can also add this feature where a Text entry works. We are back with Datagrid example here. All you have to do is follow these steps.

  1. Drag and drop a Datagrid control to your C# Windows Application.
  2. Find Data Grid’s  EditingControlShowing event using the Properties window.
  3. Create a TextBox for auto completion, using DataGridViewEditingControlShowingEventArgs object.
  4. Check for exact column where we want to place auto completion box.
  5. Create auto completion string set using AutoCompleteStringCollection class.
  6. Fill Auto completion Mode,Source and custom source properties

The Code

 String t = dataGridView1.Columns[1].HeaderText;
            if (t.Equals(“Items”))
                TextBox auto = e.Control as TextBox;
                if (auto!=null) {
                    AutoCompleteStringCollection autotxt = new AutoCompleteStringCollection();
                    auto.AutoCompleteMode = AutoCompleteMode.Suggest;
                    auto.AutoCompleteSource = AutoCompleteSource.CustomSource;
                    auto.AutoCompleteCustomSource = autotxt;
It’s looks like simple, sin’t it?
