如何从与DataKey网格视图重定向 [英] How to redirect from a grid view with the DataKey

问题描述

我想网格视图中单击某一行时重定向，所以我有OnRowCreated网格视图，我不能够重定向到我想要的页面

 ＆LT; ASP：GridView控件ID =Grid_Messagetable=服务器OnRowCreated =Grid_Messagetable_RowCreatedAllowPaging =FALSE的SelectedIndex =0
                 的DataKeyNames =的MsgIDShowHeaderWhenEmpty =真
                OnRowDataBound =MyGrid_RowDataBound的AutoGenerateColumns =FALSEAllowSorting =真
                OnSorting =gridView_SortingHEIGHT =16像素WIDTH =647px＆GT;保护无效Grid_Messagetable_RowCreated（对象发件人，GridViewRowEventArgs E）
    {
        e.Row.Attributes.Add（的onClick，this.style.background ='＃eeff00'）;
    }
 

在这里，我试图设置背景颜色单击某一行的时候，它的工作，但我怎么能重定向的页​​面，我要重定向到ResponseMetrci.aspx页面与MSGID，正如我在下面做的事情。于是我通过MSGID在URL中，以便我retreive，在响应指标页。

 评估（的MsgID，ResponseMetric.aspx的MsgID = {0}？）％GT;'
 

我想这

  e.Row.Attributes [的onClick] =location.href =
 '？ResponseMetric.aspx的MsgID =+的DataBinder.Eval（e.Row.DataItem的MsgID）+';
 

但我正在逐渐低于

错误

 未捕获的Ref​​erenceError：重定向没有定义

解决方案

简单的修复，只是改变你的的RowDataBound 方法，我可以看到你已经实施，包括以下片段：

 保护无效MyGrid_RowDataBound（对象发件人，GridViewRowEventArgs E）
{
    如果（e.Row.RowType == DataControlRowType.DataRow）
    {
        e.Row.Attributes [的onClick] =的String.Format（
            window.location的='ResponseMetric.aspx的MsgID = {0}？;，
            DataBinder.Eval的（e.Row.DataItem的MsgID））;
    }
}
 

下面是一个基本的工作的例子，只是去谷歌：

 保护无效grdTest_RowDataBound（对象发件人，GridViewRowEventArgs E）
{
    如果（e.Row.RowType == DataControlRowType.DataRow）
    {
        e.Row.Attributes [的onClick] =
            了window.location ='http://www.google.com/';;
    }
}
 

I want the grid view to redirect when a row is clicked, so I have the OnRowCreated for the grid view and I am not able to redirect to the page I wanted

<asp:GridView ID="Grid_Messagetable" runat="server" OnRowCreated="Grid_Messagetable_RowCreated" AllowPaging="False" SelectedIndex="0"
                 DataKeyNames="MsgID" ShowHeaderWhenEmpty="true"
                OnRowDataBound="MyGrid_RowDataBound" AutoGenerateColumns="False" AllowSorting="true"
                OnSorting="gridView_Sorting" Height="16px" Width="647px">     protected void Grid_Messagetable_RowCreated(object sender, GridViewRowEventArgs e)
    {
        e.Row.Attributes.Add("onClick", "this.style.background='#eeff00'");
    }

Here I tried to set background color when a row is clicked and it worked but how can I redirect the page, I have to redirect to ResponseMetrci.aspx page with the msgID, Just as I am doing below. So I pass the msgid in the url so that I retreive that in the response metric page.

Eval("MsgID", "ResponseMetric.aspx?MsgID={0}") %>'

i tried this

e.Row.Attributes["onClick"] = "location.href=
 'ResponseMetric.aspx?MsgID=" + DataBinder.Eval(e.Row.DataItem, "MsgID") + "'";

but I am getting the error below

Uncaught ReferenceError: redirect is not defined
(anonymous function)Messages.aspx:774
onclick

解决方案

Simple fix, just change your RowDataBound method which I can see you already have implemented to include the following snippet:

protected void MyGrid_RowDataBound(Object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        e.Row.Attributes["onClick"] = string.Format(
            "window.location = 'ResponseMetric.aspx?MsgID={0}';",
            DataBinder.Eval(e.Row.DataItem, "MsgID"));
    }
}

Here is a basic working example that just goes to Google:

protected void grdTest_RowDataBound(Object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        e.Row.Attributes["onClick"] =
            "window.location = 'http://www.google.com/';";
    }
}
