Autocomplete datagridview inside datagridview

Question

I am working on a c# windows based project where I am trying to pop up a datagridview containing suggestive words whenever I enter the specified cell ie Textboxcolumn of datagridview .Can someone please share the details how to do so.

@ankit goel , Welcome to Microsoft Q&A, based on my test, I find that Textboxcolumn may be not a good choice to show the suggestive words. I recommend that you used DataGridViewComboBoxColumn.

Here is a code example you could refer to.

 private void Form1_Load(object sender, EventArgs e)  
        {  
  
            DataGridViewComboBoxColumn column =  
             new DataGridViewComboBoxColumn();  
            {  
                column.DataPropertyName = "Name";  
                column.HeaderText = "Name";  
                column.DropDownWidth = 160;  
                column.Width = 90;  
                column.MaxDropDownItems = 3;  
                column.FlatStyle = FlatStyle.Popup;  
            }  
            column.Items.Add("Jack");  
            column.Items.Add("Jason");  
            column.Items.Add("John");  
            dataGridView1.Columns.Insert(0,column);  
  
        }  
        private void dataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)  
        {  
            if (dataGridView1.CurrentCell.ColumnIndex == 0)  
            {  
                ComboBox combo = e.Control as ComboBox;  
  
                if (combo == null)  
                    return;  
  
                combo.DropDownStyle = ComboBoxStyle.DropDown;  
                combo.AutoCompleteMode = AutoCompleteMode.SuggestAppend;  
            }  
        }  

Result:

Hope this could help you.
