Thank you for writing.
You can achieve auto complete functionality in a GridViewTextBoxColumn cell by changing the cell editor with a custom one, holding RadAutoCompleteBoxElement. Attached you can find a sample of this.
I hope this helps.

Hi,
I'm currently looking for the same thing but it looks like the link to the sample is broken.
Is it possible to update it ?
Thank you for writing.
When I download the project, then remove all references and add them anew by using the DLLs from the installation on my machine, everything works as expected. Please refer to the attached gif file demonstrating the behavior on my end with the latest version.
I hope this information helps. Should you have further questions I would be glad to help.

Hello Dess,
In fact my problem is about downloading the project files. I get 404 error page when I click on the link (same about your picture file).
I will check it on another computer and network.
Best regards

Hello Dess,
It's always the same on my personnal or work computer. All links give me the same error.
I attach a picture of the error page.
Thank you for writing back.
Currently, we are experiencing an issue with the attachments in the public forums. Please excuse us for the inconvenience caused.The problem will be addressed as soon as possible.
You can find below the complete code snippet that the project contains:
private void Form1_Load(object sender, EventArgs e){ this.customersTableAdapter.Fill(this.nwindDataSet.Customers); this.radGridView1.DataSource = this.customersBindingSource; radGridView1.EditorRequired += radGridView1_EditorRequired; radGridView1.CellEditorInitialized += radGridView1_CellEditorInitialized; radGridView1.AutoSizeRows = true;}void radGridView1_EditorRequired(object sender, Telerik.WinControls.UI.EditorRequiredEventArgs e){ if (radGridView1.CurrentColumn.Name == "Country") { e.Editor = new MyAutoCompleteEditor(); }}void radGridView1_CellEditorInitialized(object sender, Telerik.WinControls.UI.GridViewCellEventArgs e){ if (e.ActiveEditor is MyAutoCompleteEditor) { DataTable uniqueCountries = nwindDataSet.Tables[0].DefaultView.ToTable(true, "Country"); MyAutoCompleteEditor editor = (MyAutoCompleteEditor)e.ActiveEditor; RadAutoCompleteBoxElement element = (RadAutoCompleteBoxElement)editor.EditorElement; element.Delimiter = ' '; element.AutoCompleteDataSource = uniqueCountries; element.AutoCompleteDisplayMember = "Country"; element.AutoCompleteValueMember = "Country"; }}class MyAutoCompleteEditor : RadTextBoxControlEditor{ protected override Telerik.WinControls.RadElement CreateEditorElement() { return new RadAutoCompleteBoxElement(); } public override void OnKeyDown(System.Windows.Forms.KeyEventArgs e) { RadAutoCompleteBoxElement element = this.EditorElement as RadAutoCompleteBoxElement; if (element.IsAutoCompleteDropDownOpen) { return; } base.OnKeyDown(e); } }I hope this information helps. If you have any additional questions, please let me know.

looking into properties I just found how to make it work like textbox:
private void Grid_CellEditorInitialized(object sender, GridViewCellEventArgs e)
{
if (e.Column.Name == "columnname")
{
RadTextBoxEditor editor = (RadTextBoxEditor)e.ActiveEditor;
var element = editor.EditorElement as RadTextBoxEditorElement;
element.TextBoxItem.TextBoxControl.AutoCompleteMode = AutoCompleteMode.Suggest;
element.TextBoxItem.TextBoxControl.AutoCompleteCustomSource.AddRange(YourSource);
element.TextBoxItem.TextBoxControl.AutoCompleteSource = AutoCompleteSource.CustomSource;
}
}
Just make an extension method and be happy
