Only first item firing OnCommandEvent.
I achieve this issue with this codes
//aspx<input type="button" id="btnDelete" onclick='<%# String.Format("javascript:return SaveWithParameter(\"{0}\")", Eval("AdressId").ToString()) %>' value="Sil"/> //javascript <script type="text/javascript"> function SaveWithParameter(parameter) { __doPostBack('btnDelete', parameter) }</script>//cs if (Request["__EVENTARGUMENT"] != null && Request["__EVENTTARGET"] != null) { string parameter = Request["__EVENTARGUMENT"]; // parameter string target = Request["__EVENTTARGET"]; // btnSave if (target == "btnDelete") { SqlDataSourceAdress.DeleteParameters["AdressId"].DefaultValue = parameter; SqlDataSourceAdress.Delete(); } }
