为CheckBoxList每个项目添加一张图片

 

参考下图，可看到效果，为CheckBoxList每个项目添加一张图片。

 

准备五张图片，如上图，和CheckBoxList项目数据：

private Dictionary<string, string> Operation()
    {
        Dictionary<string, string> o = new Dictionary<string, string>();
        o.Add("i","Insert");
        o.Add("e","Edit");
        o.Add("c","Cancel");
        o.Add("u","Update");
        o.Add("d","Delete");
        return o;
    }

 

然后在.aspx，并使用OnDataBound事件:

 <asp:CheckBoxList ID="CheckBoxListOperation" runat="server" RepeatColumns="1" RepeatDirection="Horizontal" OnDataBound="CheckBoxListOperation_DataBound">
            </asp:CheckBoxList>

 

.aspx.cs：

 protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            Data_Binding();
        }
    }

    private void Data_Binding()
    {
        this.CheckBoxListOperation.DataSource = Operation();
        this.CheckBoxListOperation.DataTextField = "value";
        this.CheckBoxListOperation.DataValueField = "key";
        this.CheckBoxListOperation.DataBind();
    }

 

OnDataBound="CheckBoxListOperation_DataBound"事件：

protected void CheckBoxListOperation_DataBound(object sender, EventArgs e)
    {
        var cbl = sender as CheckBoxList;
        foreach (ListItem li in cbl.Items)
        {
            li.Text = string.Format("<img src='Images/{0}.gif' /> {1}", li.Value, li.Text);
        }
    }
