c# img 在 RowDatabound 上应用 onclick 属性

Question

在我的 gridview 中用 c# 编辑单行是可能的。

    <asp:TemplateField ItemStyle-HorizontalAlign="Center">
        <ItemTemplate>
            <asp:ImageButton 
                ID="imgbtnEdit" 
                CommandName="Edit" 
                runat="server"
                ImageUrl='<%# Eval("Stopped").ToString().Equals("1") ? 
                "/aspnet/img/edit_1.gif" : 
                "/aspnet/img/edit_2.gif" %>'
                OnClientClick="if (!confirm('Confirm ?')) return false;" />
        </ItemTemplate>
    </asp:TemplateField>

protected void gv_RowEditing(object sender, GridViewEditEventArgs e)
{
    string sID = gv.DataKeys[e.NewEditIndex].Value.ToString();
    string queryString = "Default2.aspx?sID=" + sID.ToString();
    string newWin = "var Mleft = (screen.width/2)-(1200/2);
                     var Mtop = (screen.height/2)-(700/2);
                     window.open('" + queryString + "','_blank',
                    'height=600,width=600,
                     status=yes,toolbar=no,scrollbars=yes,menubar=no,
                     location=no,top=\'+Mtop+\', 
                     left=\'+Mleft+\';');";
    ClientScript.RegisterStartupScript(this.GetType(), "pop", newWin, true);
}

在rowdatabound事件中，当单元格二的值等于零时，我添加了这个条件：

protected void gv_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {                       
        ImageButton img = (ImageButton)e.Row.FindControl("imgbtnEdit");

        if (e.Row.Cells[2].Text.Equals("0"))
        {
            img.ImageUrl = "/aspnet/img/stop.gif";
            img.Width = 18;
            img.Height = 18;
            img.Enabled = true;

            e.Row.Cells[1].Attributes.Add("onClick", "alert('Cell 1 Clicked');");
        }
    }
}

但是单击图像 stop.gif 首先打开带有 Confirm? 消息的警报，最后打开带有 Cell 1 Clicked 消息的警报，并在 window 中打开弹出 asp 页 Default2.aspx 用于编辑行。

在这种情况下我需要：

只打开警报 Cell 1 Clicked;
打开新的 aspx 页面 Default3.aspx.

如何解决这个问题？

提前感谢您的帮助。

希望对您有所帮助。

protected void gv_RowEditing(object sender, GridViewEditEventArgs e)
{    
    int xCount = Int32.Parse(gv.Rows[e.NewEditIndex].Cells[2].Text);

    if (xCount > 0)
    {        
       string sID = gv.DataKeys[e.NewEditIndex].Value.ToString();
       string queryString = "Default2.aspx?sID=" + sID.ToString();
       string newWin = "var Mleft = (screen.width/2)-(1200/2);
                        var Mtop = (screen.height/2)-(700/2);
                        window.open('" + queryString + "','_blank',
                       'height=600,width=600,
                        status=yes,toolbar=no,scrollbars=yes,menubar=no,
                        location=no,top=\'+Mtop+\', 
                        left=\'+Mleft+\';');";
       ClientScript.RegisterStartupScript(this.GetType(), "pop", newWin, true);    
    }
}

protected void gv_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {                       
        ImageButton img = (ImageButton)e.Row.FindControl("imgbtnEdit");

        if (e.Row.Cells[2].Text.Equals("0"))
        {
            img.ImageUrl = "/aspnet/img/stop.gif";
            img.Width = 18;
            img.Height = 18;
            img.Enabled = true;

            img.OnClientClick = "";
            img.Attributes["onclick"] = "if(!confirm('...')){return false;};";//open Default3.aspx
        }
    }
}
