[Dai Thanh]

Hi,

I have problem, i create RadGrid by code and registry event ItemDataBound,

 void dataGrid_ItemDataBound(object sender, GridItemEventArgs e)
        {
           if (e.Item is GridFooterItem)
            {
                GridFooterItem footer = (GridFooterItem)e.Item;
              
                    string interName = "name";
                    footer[interName].Controls.Add(new LiteralControl("<b>" + GetLabel("Goto", "Go to") + " </b>"));
                    LinkButton lbtIndex = new LinkButton();
                    lbtIndex .Text ="1";
                    lbtIndex .ID = "lbl1";
                    lbtIndex .Click += new EventHandler(lbtIndex _click);
                    footer[interName].Controls.Add(lbtIndex );
              
            }
        }
        void lbtIndex _click(object obj, EventArgs e)
        {
         //to do
       }

But when i click LinkButton 1 (lbtIndex _click), the event of button dont fire.

Hello Dai Thanh,

You have to add the LinkButton in the ItemCreated handler, otherwise it will disappear when you click it.

Hello Daniel

I added the LinkButton in the ItemCreated handler but lbtPageNumber_Click not working, just fire event linkButtonBack_Click .

 void dataGrid_ItemCreated(object sender, GridItemEventArgs e)
        {
            if (e.Item is GridPagerItem)
            {
                GridPagerItem pagerItem = (GridPagerItem)e.Item;
                pagerItem.PagerContentCell.Controls.Clear();
       
                LinkButton linkButtonBack = new LinkButton();
                linkButtonBack.ID = "lbtBack";
                linkButtonBack.Text = "Back";
                linkButtonBack.Click += new EventHandler(linkButtonBack_Click);
                linkButtonBack.Font.Underline = false;
                linkButtonBack.Attributes.Add("style","margin: 0px 5px 0px 15px");
                linkButtonBack.CommandName = "page";
                linkButtonBack.CommandArgument = "1";
                pagerItem.PagerContentCell.Controls.Add(linkButtonBack);
           
               //~~~Add Number Paging ~~~//
            
                int i = 0;
                while (i < this.totalPage)
                {
                    i += 1;
                    LinkButton lbtPageNumber = new LinkButton();
                    lbtPageNumber.ID = "lbtPageNumber" + i;
                    lbtPageNumber.Font.Underline = false;
                    lbtPageNumber.Text = i.ToString();
                    lbtPageNumber.Attributes.Add("style", "margin: 0px 2px 0px 2px");
                    lbtPageNumber.CommandName = "page";
                    lbtPageNumber.CommandArgument =i.ToString ();
                    lbtPageNumber.Font.Underline = false;
                    lbtPageNumber.Click += new EventHandler(lbtPageNumber_Click);
                     pagerItem.PagerContentCell.Controls.Add(lbtPageNumber);

                }
              
            }
        }

 void linkButtonBack_Click(object sender, EventArgs e)
        {
          //to do
        }
        void lbtPageNumber_Click(object sender, EventArgs e)
        {
          //to do
        }

Hello Dai,

  Your code works properly on my end. Please test the attached demo and let me know whether the link buttons behave as expected when you run it locally.
