asp. net Gets the line number of the current line in ListView and gridview

This article illustrates how asp. net gets the line number of the current line in ListView and gridview. Share it for your reference, as follows:

In aspx, in gridview/ListView, there is a template column called linkbutton, and when you want to click it, get the index value of its row

In ListView:

Type 1:

<ItemTemplate>
 <tr>
  <td>
  <asp:LinkButton runat="server" ID="btnSelected" Text='<%# (Container.DisplayIndex+1).ToString() %>' ></asp:LinkButton>
   </td>
 </tr>
</ItemTemplate>

Type 2:

<ItemTemplate>
 <li>
  <asp:LinkButton ID="btnDelete" runat="server" CommandName="Delete"
   Text="<%# Container.DataItem %>"></asp:LinkButton>
 </li>
</ItemTemplate>

In gridview

Type 1:

<itemtemplate>
  <asp:LinkButton ID="LinkButton1" runat="server"
</itemtemplate>

protected void LinkButton1_Click(object sender, EventArgs e)
{
  // Line number 
  int row = ((GridViewRow)((LinkButton)sender).NamingContainer).RowIndex;
}

Type 2:

<asp:GridView ID="gvTest" runat="server">
  <Columns>
  <asp:TemplateField>
  <ItemTemplate>
  DisplayIndex : <%# Container.DisplayIndex %> || DataItemIndex : <%# Container.DataItemIndex %><br />
  </ItemTemplate>
  </asp:TemplateField>
  </Columns>
</asp:GridView>

I hope this article is helpful to everyone's asp. net programming.
