"not Firing any suggestion" ..How can it fire a suggestion ?

I think that simply a grammar mistake and the sentences sounds to be like this:
......but its not Firing. Any suggestion?

First Add Your link Button and Div message in .ASPX

<asp:LinkButton ID="ancDelete" CommandName="delete" OnCommand="delete_EventCategories" runat="server">Delete </asp:LinkButton>

XML

<div id="divMessage" runat="server" class="grid_7 alpha" style="display: none;">
        <asp:Literal runat="server" ID="ltlMessage" Text="test"></asp:Literal>
    </div>

Then write a Show method.

C#

public static void ShowMessage(string _class, string msg, System.Web.UI.HtmlControls.HtmlGenericControl divMessage, Literal ltlMessage)
       {
           divMessage.Style.Add("display", "block");
           divMessage.Attributes.Add("class", _class);
           ltlMessage.Text = msg;
       }

And finally Event Hadelers.

C#

protected void delete_EventCategories(object Sender, CommandEventArgs e)
        {
            if (e.CommandName == "delete")
            {
                try
                {

             ShowMessage("alert alert-success", " Successfully!",divMessage, ltlMessage);
                }
                catch (Exception ex)
                {

                  ShowMessage("alert alert-error", ex.InnerException.Message, divMessage,ltlMessage);
                }
            }
        }

If it is matter of dynamic link control then just mind it that its state not persist my ASP.net framework with the help of view state. For example if you create a link button like as follows

ASP.NET

<div id="divLink"  runat="server">
</div>

C#

if (!base.IsPostBack)//comment out this condition if you want to fire Click event 
{
    var control = new LinkButton();
    control.Text = "Clik ME";           
    control.Click += control_Click;
    divLink.Controls.Add(control);
}

C#

void control_Click(object sender, EventArgs e)
{
    Response.Write("............................");
}

You see that next postback event the LinkButton not showing and event not firing.
If you want to fire that event you need to create that dynamic control every request (either postback or not postback.
