Telerik.WinControls.UI.RadTextBox Enter key issue.

Hi, Sathish,

In order to have multiple lines in RadTextBox, its Multiline property should be set to true. Then, if you want the Enter key to create and go to the next line, you need to set the AcceptsReturn property also to true.

            this.radTextBox1.Multiline = true;
            this.radTextBox1.AcceptsReturn = true;

I hope this information helps. If you need any further assistance please don't hesitate to contact me.
