Not "inside the button click event" (what would it mean?!), in event handler. You need to get data from the selected cell and present it the way you want somewhere else, to represent detail. That's it.

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

XML

<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>

Now call the below method

C#

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

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">

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

XML

 <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>

II. Now write code for gridview_OnRowCommand

C#

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.
  
    }
}

I hope it will help you.

Good luck.
