Grid View Combo Box Column with suggest mode contains

[Usman]

Hello, i need to change the suggest mode of GridViewComboBoxColumn to SuggestMode.Contains. just like we can do it on dropdown control, how can i dot it. 
i am using winforms q2 2014 sp1 version controls.

var column= new GridViewComboBoxColumn
                {
                    DataSource = ClsProducts.GetActiveProducts(),
                    DisplayMember = "ProductName",
                    ValueMember = "ProductID",
                    Width = 280,
                    HeaderText = "Product",
                    Name = "ColProduct",
                    DropDownStyle = RadDropDownStyle.DropDown,
                    AutoCompleteMode = AutoCompleteMode.SuggestAppend
                };
                dgvTrade.Columns.Insert(1, column);

Hello, Usman,

In order to set the AutoCompleteSuggest mode to Contains in GridViewComboBoxColumn you should handle the CellEditorInitialized event as follows:

public RadForm1()
{
    InitializeComponent();
    GridViewComboBoxColumn customerColumn = new GridViewComboBoxColumn("Categories");
    customerColumn.DataSource = this.categoriesBindingSource;
    customerColumn.ValueMember = "CategoryID";
    customerColumn.DisplayMember = "CategoryName";
    customerColumn.FieldName = "CategoryID";
    customerColumn.AutoCompleteMode = AutoCompleteMode.Suggest;
    this.radGridView1.Columns.Add(customerColumn);
    this.radGridView1.CellEditorInitialized += this.RadGridView1_CellEditorInitialized;
}

private void RadGridView1_CellEditorInitialized(object sender, GridViewCellEventArgs e)
{
    RadDropDownListEditor editor = e.ActiveEditor as RadDropDownListEditor;
    if (editor != null)
    {
        RadDropDownListEditorElement el = editor.EditorElement as RadDropDownListEditorElement;
        el.DropDownStyle = Telerik.WinControls.RadDropDownStyle.DropDown;
        el.AutoCompleteMode = AutoCompleteMode.Suggest;
        el.AutoCompleteSuggest.SuggestMode = SuggestMode.Contains;
    }
}
