To reproduce: the attached gif file illustrates the behavior. public Form2() { InitializeComponent(); this.radGridView1.DataSource = this.customersBindingSource; this.radGridView1.CellClick += radGridView1_CellClick; } private void radGridView1_CellClick(object sender, Telerik.WinControls.UI.GridViewCellEventArgs e) { this.radDataLayout1.DataSource = e.Row.DataBoundItem; this.radDataEntry1.DataSource = e.Row.DataBoundItem; } private void Form2_Load(object sender, EventArgs e) { // TODO: This line of code loads data into the 'nwindDataSet1.Customers' table. You can move, or remove it, as needed. this.customersTableAdapter.Fill(this.nwindDataSet1.Customers); }
