Question

asp.net中GridView下的HyperLinkField中，在点击一个连接时如何触发一个事件，遍历链接到该文件下的图片

急啊，小妹万分感谢

Answer 1

给你一个模版。我这个模版实现的功能是，当点击gridview中的超链接按钮时，将弹出被点击的超连接编号的详细信息。估计你要的和我这个差不了多少。
首先在前台页面放一个LinkButton
<asp:LinkButton ID="lbtnNull" runat="server" Text="Null"
onclick="lbtnNull_Click" Visible="false"></asp:LinkButton>
后台事件如下
protected void lbtnNull_Click(object sender, EventArgs e)
{
D_Bind_P();
gvData_P.Visible = true;
}
简单吧。下面是D_Bind_P()的代码
protected void D_Bind_P()
{
strMate_No = Request.QueryString["mate"].ToString().Trim();
string strTb_Nm = null;
string s = ddlBrand.SelectedValue.ToString().Trim();
switch (ddlBrand.SelectedValue)
{
case "v_LOGO_HondaOutin_MaterialMst":
strTb_Nm = "v_LOGO_Product_Mst";
break;
case "LOGO_hzr_honda_outin_material_mst":
strTb_Nm = "LOGO_HondaOutin_bom_mst_dtl_Tb";
break;
case "LOGO_hzr_nissan_outin_material_mst":
strTb_Nm = "LOGO_NissanOutin_bom_mst_dtl_Tb";
break;
}
if (rbtnUN_Confirm.Checked == true)
{
//待确认按钮
strSql = "select product_no,cusdesch_c1,cusdesch_c2,intdesch_c ";
strSql += " from " + strTb_Nm + " where rtrim(ltrim(product_no))+";
strSql += "rtrim(ltrim(cusdesch_c1))+rtrim(ltrim(cusdesch_c2))+rtrim(ltrim(intdesch_c)) not in ";
strSql += "(select rtrim(ltrim(Product_no))+rtrim(ltrim(Cusdesch_c1))+rtrim(ltrim(Cusdesch_c2))+";
strSql += "rtrim(ltrim(Intdesch_c)) from LOGO_ProductReveal_Tb)";
strSql += " and material_no='" + strMate_No + "'";
if (dc.gvBind(strSql, "0", gvData_P) == false)
{
bc.MsgBox("品番清单加载不成功");
return;
}
gvData4.Visible = false;
gvData_P.Visible = true;
}
if (rbtnConfirm.Checked == true)
{
//已确认按钮
//不需要理会商标类型
strTb_Nm = "LOGO_ProductReveal_Tb";
strSql = "select Product_no,Cusdesch_c1,Cusdesch_c2,Intdesch_c,Reveal_Flg from " + strTb_Nm + " where ";
strSql += "Material_no='" + strMate_No + "'";
if (dc.gvBind(strSql, "0",gvData4) == false)
{
bc.MsgBox("品番清单加载不成功");
return;
}
gvData_P.Visible = false;
gvData4.Visible = true;
}
}
最后顺便把gridview的前台代码发给你吧
<asp:GridView ID="gvData_M" runat="server" BackColor="White"

</asp:GridView>

• hyperlinkfield 应该可用直接有onclick 事件把,直接点击了,

• 如果要遍历链接地址那边路径的文件下的图片的话,应该要在链接那边实现,并返回那些图片把.

这个，你最好自己放一个服务器控件，而不要用gridview自带的这个HyperLinkField，你自己放一个服务器控件，就很方便写click事件了。
