i am using the gridview in that i use the link button. but i don`t get the row index for the clicked the link button. so please help me.

int index = System.Convert.ToInt32(e.CommandArgument);
LinkButton link_button =(LinkButton)GridView1.Rows[index].FindControl("link1");
Label l1 = (Label)GridView1.Rows[index].FindControl("Label2");


in column filed of grid. i use......

<asp:TemplateField HeaderText="Title">
       <ItemTemplate>
           <asp:Label ID="Label2" runat="server" Text='<%#Eval("title")%>' Visible="false"></asp:Label>

< asp:LinkBut​​ton ID ="link1" runat ="server" Text =''<％#Eval("title")％>''CommandName ="link" ForeColor ="Blue">

<asp:LinkButton ID="link1" runat="server" Text=''<%#Eval("title")%>'' CommandName="link" ForeColor="Blue">

</ItemTemplate>

           <ItemStyle ForeColor="Blue" Font-Size="Medium"  />

       </asp:TemplateField>

推荐答案

使用:CommandArgument=''<%# Container.DataItemIndex %>''

上面的示例用法:
以下将ItemName绑定到LinkButton的CommandArgument.

Use: CommandArgument=''<%# Container.DataItemIndex %>''

Sample use of the above:
Following binds the ItemName to the CommandArgument of the LinkButton.

<asp:LinkButton ID="LinkButton1" runat="server" Text="Add to cart"

   OnClick="LinkButton1_Click" CommandArgument='<%# Container.DataItemIndex %>' />

然后，您可以在后面的代码中像这样检索它:

You can then retrieve it like this in the code behind:

protected void LinkButton1_Click(object sender, EventArgs e)
{
  LinkButton myButton = sender as LinkButton;
  if (myButton != null)
  {
     string rowIndex = myButton.CommandArgument;
     // use this rowIndex now as per your need
  }
}

发送方持有对触发事件处理程序的LinkButton的引用.
您可以将对象转换为LinkButton，然后检索其CommandArgument并将其转换为字符串.

The sender holds a reference to the LinkButton that triggered the event handler.
You can cast the object into a LinkButton and then retrieve its CommandArgument and cast that into string.
