在datalist命令上，我编写了这样的代码
protected void DataListShowImgTxt_ItemCommand(object source, DataListCommandEventArgs e)
{
string id = DataListShowImgTxt.DataKeys[e.Item.ItemIndex].ToString();
//DataListItem tem = DataListShowImgTxt.Items[e.Item.ItemIndex] as DataListItem;
//TextBox txtcmnet = tem.FindControl("txtcomment") as TextBox;
createDt.commonAll("Select UserName from imagedb where imgid='" + id + "'", "searchimage");
string u_name = createDt.GroupDS.Tables["searchimage"].Rows[0]["UserName"].ToString();
if (e.CommandName == "SaveImage")
{
clickpic =Convert.ToInt32(DataListShowImgTxt.DataKeys[e.Item.ItemIndex].ToString());
DataListItem teme = DataListShowImgTxt.Items[e.Item.ItemIndex] as DataListItem;
ImageButton imgbtn = teme.FindControl("Image3") as ImageButton;
imglightbox.ImageUrl = imgbtn.ImageUrl;
ScriptManager.RegisterStartupScript(Page, typeof(Page), "ShowValidation", "javascript:ShowImages();", true);
hovercoment(clickpic);
showhoverlikComment(clickpic);
}
if (e.CommandName == "like")
{
////string id = DataListShowImgTxt.DataKeys[e.Item.ItemIndex].ToString();
createDt.commonAll("insert into likeimgdb(ImgId,UserName,LikeUser,Status,LikeImgDate) values('" + id + "','" + LoginUser + "','" + u_name + "','Like','"+DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss")+"')", "insertimage");
//LinkButton st = tem.FindControl("LinkButton8") as LinkButton;
if (flag == 0)
{
ShowAllFriendsImage1(LoginUser);
}
else if (flag == 1) {
ShowAllFriendsImage(selectUser);
}
}
我想刷新我的网页只有当命令名是saveimage
时才会刷新我的网页所以请指导我如何刷新它
其实我的设计是这样的
<asp:LinkButton ID="LinkButton1" runat="server" PostBackUrl='<% #Eval("Photo")%>' >
<asp:Image ID="Image2" runat="server" ImageUrl='<% #Eval("Photo")%>' Height="60px"
Width="65px" />

我想在commandname = SaveImage上打开图像，并在命令名= like上像counter一样更新 这两个都工作正常，但当我点击它移动到开始页面的位置 我希望它只是更新计数而不是开始
答案 0 :(得分：0)
使用它，
Response.Redirect(Request.RawUrl);
将此代码置于您的状态
if (e.CommandName == "like")
{
////string id = DataListShowImgTxt.DataKeys[e.Item.ItemIndex].ToString();
createDt.commonAll("insert into likeimgdb(ImgId,UserName,LikeUser,Status,LikeImgDate) values('" + id + "','" + LoginUser + "','" + u_name + "','Like','"+DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss")+"')", "insertimage");
//LinkButton st = tem.FindControl("LinkButton8") as LinkButton;
if (flag == 0)
{
ShowAllFriendsImage1(LoginUser);
}
else if (flag == 1) {
ShowAllFriendsImage(selectUser);
}
Response.Redirect(Request.RawUrl);
}
