Asp.net 如何将网格视图值中的选定行id传递给重定向url

我有一个gridview来显示表中的请求信息。 我已经添加了一个按钮模板feild，单击该模板后，应该会将用户带到相应的请求url

如何捕获所选requestid并将其作为重定向url中的变量传递

我的gridview

    </SelectParameters>

</asp:SqlDataSource>

</div>

您需要事件，以及，以便在rowcommand事件中传递值

Html

<ItemTemplate>
           <asp:Button ID = "button2" runat = "server" CommandName="cmdYourButtonPurpose" CommandArgument='<%# Bind("roc_id") %>'
                Text='<%# Bind("roc_id") %>' />
</ItemTemplate>

试试这个

protected void CustomersGridView_SelectedIndexChanged(Object sender, EventArgs e)
{    
     GridViewRow row = GridView1.SelectedRow;   
     string roc_id = GridView1.DataKeys[row.RowIndex].ToString();

     string url = String.Format("http://xxx.yahoo.com/testing/adhoc/Edit.asp?ROCID={0}", roc_id);
     Response.Redirect(url);   
}

在我像以前一样单击按钮进行更改后，它什么也不做。只有属性才支持双向绑定。”CommandArguments不是Button的有效属性。我认为错误是由于在asp:Button中键入错误造成的。我键入的是CommandArguments，而不是CommandArguments。现在更正，尝试一下。As asp:Button support CommandArgument获取此错误编译器错误消息：CS0029:无法将类型“System.Web.UI.WebControl.DataKey”隐式转换为“string”源错误：第67行：GridViewRow行=GridView1.SelectedRow；第68行：第69行：字符串roc_id=GridView1.DataKeys[row.RowIndex]；第70行：第71行：Response.Redirect（“+roc_id”）；Iam使用下面的，它不会重定向受保护的无效GridView1\u SelectedIndexChanged（对象发送方，EventArgs e）{GridViewRow=GridView1.SelectedRow；string roc\u id=GridView1.DataKeys[row.RowIndex].ToString（）；string url=string.Format（“{0}”，roc\u id）；Response.redirect（url）；}我仍然在寻求帮助，因为我无法解决这个isuue

void ContactsGridView_RowCommand(Object sender, GridViewCommandEventArgs e)
{
     if(e.CommandName=="cmdYourButtonPurpose")
     {   
         Response.Redirect("http://xxx.yahoo.com/testing/adhoc/Edit.asp?ROCID=" + e.CommandArgument.ToString(););
     }
}

protected void CustomersGridView_SelectedIndexChanged(Object sender, EventArgs e)
{    
     GridViewRow row = GridView1.SelectedRow;   
     string roc_id = GridView1.DataKeys[row.RowIndex].ToString();

     string url = String.Format("http://xxx.yahoo.com/testing/adhoc/Edit.asp?ROCID={0}", roc_id);
     Response.Redirect(url);   
}
