Can we show partial data with read more option in grid view

<asp:templatefield headertext="Description" xmlns:asp="#unknown">
 <itemtemplate>
      <asp:label id="lblDescription" runat="server">
                Text='<%# Limit(Eval("Description"),40) %>' 
                Tooltip='<%# Eval("Description") %>'>
      </asp:label>
      <asp:linkbutton id="ReadMoreLinkButton" runat="server">
                Text="Read More"
                Visible='<%# SetVisibility(Eval("Description"), 40) %>'
                OnClick="ReadMoreLinkButton_Click">
      
 </asp:Label>
 </ItemTemplate>
</asp:TemplateField>

protected bool SetVisibility(object Desc, int length)
{
    return Desc.ToString().Length > length;
}
protected void ReadMoreLinkButton_Click(object sender, EventArgs e)
{
    LinkButton button = (LinkButton)sender;
    GridViewRow row = button.NamingContainer as GridViewRow;
    Label descLabel = row.FindControl("lblDescription") as Label;
    button.Text = (button.Text == "Read More") ? "Hide" : "Read More";
    string temp = descLabel.Text;
    descLabel.Text = descLabel.ToolTip;
    descLabel.ToolTip = temp;
}
