我保留一个名为id的变量,它保留了来自db (id = row[3].ToString();)
然后我将类yildiz的id分配给'id'然后我尝试传递c#函数但是我不能这样做。
当在click事件中,id的值是“id”(我尝试的代码是(string id = objImage.UniqueID; objImage.ID
))但实际上它必须是诸如“26”之类的值
来自db,但它没有。
实际上我的问题是在c#侧处理数据。我也尝试了命令参数,但我不能这样做有任何办法,我怎么能解决这个问题?感谢..
id = row[3].ToString();

ImageUrl="~/images/yildiz.png" OnClick="ImageButton2_Click" Width="20px"
style="position: relative; top: 13px; left:6px; float:left; " /></div>
<% } %>
是c#side
protected void ImageButton2_Click(object sender, ImageClickEventArgs e)
{
ImageButton objImage = (ImageButton)sender;
string id = objImage.UniqueID;
/* if (e.CommandName == "Comment")
{
string[] commandArgs = e.CommandArgument.ToString().Split(new char[] { ',' });
string scrapid = commandArgs[0];
string uid = commandArgs[1];
} */
// string s= Imageid.UniqueID.ToString();
//this.baslik2.Text = s;
}
答案 0 :(得分:1)
你正在设置ID = id,这就是为什么我认为你正在把它作为一串“id”读回来...我觉得你真正想做的就是这样设置:
ID = LT;%= ID%&GT;
编辑:
是的,它在我的预期中不起作用......
我将其改编为以下内容:
<asp:Panel id="test" class="yildiz" runat="server"></asp:Panel>
和page_load:
protected void Page_Load(object sender, EventArgs e)
{
var i = 2;
var id = 2;
for (var j = i * 5 + 1; j < (i *5)+6; j++)
{
var imagebutton = new ImageButton();
imagebutton.ID = id.ToString( );
imagebutton.ImageUrl = "https://www.google.com/logos/2012/juan_gris-2012-hp.jpg";
imagebutton.Style.Add("position","relative");
imagebutton.Style.Add("top","13px");
imagebutton.Style.Add("left","6px");
imagebutton.Style.Add("float","left");
test.Controls.Add(imagebutton);
}
}
然而,这有错误:
找到具有相同ID“2”的多个控件。的FindControl 要求控件具有唯一ID。
然而,这将起作用:
protected void Page_Load(object sender, EventArgs e)
{
var i = 2;
var id = 2;
for (var j = i * 5 + 1; j < (i *5)+6; j++)
{
var imagebutton = new ImageButton();
imagebutton.Attributes.Add("custom-id", id.ToString( ));
imagebutton.ImageUrl = "https://www.google.com/logos/2012/juan_gris-2012-hp.jpg";
imagebutton.Style.Add("position","relative");
imagebutton.Style.Add("top","13px");
imagebutton.Style.Add("left","6px");
imagebutton.Style.Add("float","left");
imagebutton.Click += new ImageClickEventHandler(imagebutton_Click);
test.Controls.Add(imagebutton);
}
}
void imagebutton_Click(object sender, ImageClickEventArgs e)
{
ImageButton objImage = (ImageButton)sender;
objImage.Attributes["custom-id"];
}
