I designed a user interface to show details in a grid view(in brief). if user want to see full details of that specified row he has to click a button. then it will appear in the same page. What should I code inside the button click event?

推荐答案

这很简单，您需要调用Gridveiw行命令事件处理程序

参见首先将按钮转换为Template Column，如下所示，并给它一个命令Name，如下所示

Its Simple , You need to call the Gridveiw Row Command Event Handler

See first convert the button as Template Column , as shown below and give it a command Name as shown below

<asp:TemplateField HeaderText="Actions" meta:resourcekey="TemplateFieldResource9">                                <ItemTemplate>
<asp:ImageButton ID="imgView" ImageUrl="~/Images/View.gif" runat="server" CommandName="ViewIssueDetails" CommandArgument='<%# Eval("ISSUEID") %>' ToolTip="View Issue Details"  />
</ItemTemplate>                                                                                 </asp:TemplateField>

现在调用以下方法

Now call the below method

protected void gvTask_OnRowCommand(Object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "ViewIssueDetails")
{
 GridViewRow row;
  row = (GridViewRow)((Control)e.CommandSource).NamingContainer;
 }
}

GridviewRow Row，您可以读取Grdiveiw的每一列的值，并可以根据需要显示它.

确保您的Gridview标记了以下命令

GridviewRow Row , you can read the value of each columns of Grdiveiw and can display it as per your requirement

Make sure your Gridview has tagged to following command

<asp:GridView ID="gvMyTask" runat="server" Width="100%"OnRowCommand="gvTask_OnRowCommand" OnPageIndexChanging="gvTask_PageIndexChanging" AllowPaging="True" AutoGenerateColumns="False">

下面是一个小示例，您可以从该示例中学习:
I. GridView控件的代码:

Here is a small example you can learn from this example:
I. Code for GridView control:

 <asp:GridView id="gridview" runat="server" AutoGenerateColumns="False" OnRowCommand="gridview_OnRowCommand">
<Columns>
 <asp:Templatefield HeaderText="Id">
   <Itemtemplate>
       <asp:Label ID="lblId" runat="server" Text='<%# Eval("Id")%>' />
   </Itemtemplate>
 </asp:TemplateField>
 <asp:TemplateField>
   <Itemtemplate>
       <asp:LinkButton ID="lnkDetail" runat="server" Text="Detail"

       CommandName="Detail" CommandArgument='<%# Eval("Id")%>' />
 </Itemtemplate>
 </asp:TemplateField>
</Columns>
</asp:GridView>

二.现在为gridview_OnRowCommand
编写代码

II. Now write code for gridview_OnRowCommand

protected void gridview_OnRowCommand(object sender, GridViewCommandEventArgs e)
 {
   if(e.CommandName == "Detail")
   { 
      //retrieve the Id from CommandArgument
      int id = Convert.ToInt32(e.CommandArgument);
      //now write your code for retrieving the detail value from database.
     //then store it in to DataSet
     //Bind your GridView with that DataSourse.
  
    }
}

希望对您有帮助.

祝你好运.

I hope it will help you.

Good luck.
