错误：不包含脚本里的函数

[dyiajure]

<Columns>
    <asp:TemplateColumn HeaderText="照片">
      <ItemTemplate> 
        <asp:Image Runat="server" ID="Image1" OnLoad="scalePhoto(Image1,200,400)"
         ImageUrl='<%# FormatURL(DataBinder.Eval(Container.DataItem, "ID")) %>' />
      </ItemTemplate>
    </asp:TemplateColumn>
  </Columns>

搞不明白了

你的OnLoad应该是想设置为客户端事件

需要在你的datagrid的ItemDatabound事件中设置Image1的客户端事件

主要想让datagrid显示的图片适应页面格式的大小，不需要客户端事件啊？

别沉啊，谁来解答下

把这个函数scalePhoto贴出来看看

[dyiajure]

<script language= "JavaScript "  type= "text/javascript "> 
function scalePhoto(imgId,width,height){
 var img = document.getElementById(imgId);
 if(img != null){
  var imgWidth = img.width;
  var imgHeight = img.height; 
  if(imgWidth>width&&imgHeight>height){
   //both image's width and height are larger than required one
   var widthRate = imgWidth/width;
   var heightRate = imgHeight/height;
   if(widthRate>heightRate){
    //use width to retrieve the image
    img.width=width;
    img.height=imgHeight*(width/imgWidth);
   }else{
    img.height=height;
    img.width=imgWidth*(height/imgHeight);
   }   
  }
  else if(imgWidth>width){
   //the image width lg than the required width
   img.width=width; 
   img.height=imgHeight*(width/imgWidth);
  }
  else if(imgHeight>height){
   //the image height lg than the required
   img.height=height;
   img.width=imgWidth*(height/imgHeight); 
  }  
 }
} 
</script>

OnLoad="scalePhoto(Image1,200,400)"
改为
OnLoad="scalePhoto(this,200,400)"试试

[ouyang3857116]

Sorry，改为OnLoad="scalePhoto("Image1",200,400)"
