RadGridView display cell string value

Hi, Vitalii,

The columns in RadGridView offer the WrapText property which is relevant for each GridViewColumn: 

this.radGridView1.Columns[0].WrapText = true;

Please review this help article for more details concerning RadGridView columns.

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

Hello, Vitalii,  

I have prepared a sample code snippet for your reference which result is illustrated below:

        public RadForm1()
        {
            InitializeComponent();

            GridViewTextBoxColumn textColumn = new GridViewTextBoxColumn();
            textColumn.Width = 50;
            textColumn.WrapText = true;
            this.radGridView1.Columns.Add(textColumn);

            this.radGridView1.Rows.Add("text1 text2");
            this.radGridView1.Rows.Add("text3 " + Environment.NewLine + "text4");
        }

The text is successfully wrapped.

I have attached my sample project. Please give it a try and see how it works on your end. Am I missing something? Could you please specify the exact steps how to reproduce the problem?
