Hi Truman,
Thanks for using Syncfusion products.
Your requirement of having CellType as RTE can be achieved by adding textarea in EditItemTemplate.
Please refer to the below code-snippet.
[ASPX]
[CS]
protected void init(object s, EventArgs e)
{
HtmlTextArea textarea = s as HtmlTextArea;
GridCell gc = textarea.NamingContainer as GridCell;
textarea.Value= gc.Row.Record.GetValue("Name").ToString();
}
Please refer to the below link to download the sample application.
