if condition

HI

I have two metod in my page that  I call one of them in  pageload event  and when page is load it call metod and according to that metod my datalist1  will bind from database.

and I have repeater in my page that I bind it from database

 protected void Page_Load(object sender, EventArgs e)
    {
         BindRepeater(rptMenuE, "electricmenu1");
  if (!IsPostBack)
        {
   

            BindDropDownList(DDLcity1, "city1", "name");
            BindDropDownList(DDLstore1, "Guidcenter", "Centername");
       

            this.GetCustomersPageWise(1);

          

           

        }

  protected void ImageButton2_Click(object sender, ImageClickEventArgs e)
    {

        this.GetCustomersPageWiseStore(1);


    }

Now my problem is:

when I click on Imagebutton2 ,datalist2 will fill with GetCustomersPageWiseStore() metod but when I click on Item from repeater it call GetCustomerPageWise() metod that I call in Page_load event

I want when I click On imgebutton2 and select Item from repeater  it again call GetCustomersPageWiseStore() metod that I call in Imagebutton2_click event

How I can do it ?

Thanks alot
