Question

asp.net如何在后台控制前台页面的image控件的宽度？

前台控件代码：<asp:Image ID="imagedutiao" Height="9px" runat="server" ImageUrl="~/resource/images/dutiao.png"/>
后台代码：
protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{

int wid = int.Parse(DataBinder.Eval(e.Item.DataItem, "PRAISECOUNT").ToString());

System.Web.UI.WebControls.Image tb = (System.Web.UI.WebControls.Image)e.Item.FindControl("imagedutiao");

tb.Width = new Unit(wid);

}
}

Answer 1

这个一但输出到html就只有css和js来控制了吧。

Answer 2

Image1.Width = 100;
Image1.Height = 200;
