看看这个示例：

效果：

标记：

 <form id="form1" runat="server">
    <div>
        <dx:ASPxGridView ID="ASPxGridView1" runat="server">
            <Columns>
                <dx:GridViewDataColumn FieldName="name">
                    <DataItemTemplate>
                        <dx:ASPxTextBox ID="txt" runat="server" Text='<%# Eval("name")%>'>
                        </dx:ASPxTextBox>
                    </DataItemTemplate>
                </dx:GridViewDataColumn>
                <dx:GridViewDataColumn FieldName="birthdate">
                    <DataItemTemplate>
                        <dx:ASPxLabel ID="lbl" runat="server" Text='<%# Eval("birthdate","{0:yyyy-MM-dd}")%>'>
                        </dx:ASPxLabel>
                    </DataItemTemplate>
                </dx:GridViewDataColumn>
                <dx:GridViewDataColumn FieldName="account">
                    <DataItemTemplate>
                        <dx:ASPxLabel ID="lbl" runat="server" Text='<%# Eval("account","{0:F2}")%>'>
                        </dx:ASPxLabel>
                    </DataItemTemplate>
                </dx:GridViewDataColumn>
            </Columns>
        </dx:ASPxGridView>
    </div>

代码：

  protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                DataTable table = new DataTable();
                table.Columns.Add("name");
                table.Columns.Add("account", typeof(double));
                table.Columns.Add("birthdate", typeof(DateTime));

                DataRow row = table.NewRow();
                row["name"] = "aa";
                row["account"] = 12.123d;
                row["birthdate"] = DateTime.Now;
                table.Rows.Add(row);

                row = table.NewRow();
                row["name"] = "bb";
                row["account"] = 741.251d;
                row["birthdate"] = DateTime.Now;
                table.Rows.Add(row);

                row = table.NewRow();

                this.ASPxGridView1.DataSource = table;
                this.ASPxGridView1.DataBind();
            }
