C#: Datagridview not displaying the data

I am working on winforms application. On my form I simply drag and drop a DataGridView control and then set some of its properties using the properties window. Following is the code which I am using to populate my DataGridView. I wrote this code inside the constructor.

List<MyCustomClass> lst = new List<MyCustomClass>();
lst = LoadList(/*some params here*/);//now uptil this point everything works i.e the list contains values as desribed.
dataGridView1.DataSource = lst;

The problem is that when i run the program nothing is displayed in my DataGridView.

For more details following code represents the properties which I set using properties window

        this.dataGridView1.AllowUserToAddRows = false;
        this.dataGridView1.AllowUserToDeleteRows = false;
        this.dataGridView1.AllowUserToResizeRows = false;
        this.dataGridView1.Anchor = ((System.Windows.Forms.AnchorStyles)(((System.Windows.Forms.AnchorStyles.Top | System.Windows.Forms.AnchorStyles.Left)
                    | System.Windows.Forms.AnchorStyles.Right)));
        this.dataGridView1.AutoSizeColumnsMode = System.Windows.Forms.DataGridViewAutoSizeColumnsMode.Fill;
        this.dataGridView1.BackgroundColor = System.Drawing.Color.White;
        this.dataGridView1.ColumnHeadersHeightSizeMode = System.Windows.Forms.DataGridViewColumnHeadersHeightSizeMode.AutoSize;
        this.dataGridView1.GridColor = System.Drawing.Color.White;
        this.dataGridView1.Location = new System.Drawing.Point(2, 329);
        this.dataGridView1.Margin = new System.Windows.Forms.Padding(2);
        this.dataGridView1.MultiSelect = false;
        this.dataGridView1.Name = "dataGridView1";
        this.dataGridView1.RowHeadersVisible = false;
        this.dataGridView1.SelectionMode = System.Windows.Forms.DataGridViewSelectionMode.FullRowSelect;
        this.dataGridView1.Size = new System.Drawing.Size(334, 106);
        this.dataGridView1.TabIndex = 0;

I've got nearly the same thing today, the problem was that my clas had public fields, not properties, since i've changed them to public auto properties - worked well for me.

You have to create Data Columns for your datagrid. Make sure you also set 'DataPropertyName' property of each column with the respected DataSource item's property (i.e., property of 'MyCustomClass' class).
