I am new to asp.net and i am stuck for last 2 days ..i am making simple asp.net/sql application, on main page i have a search button which open ups a popup where i have text box and criteria for search and a button Btok when user hits the button application fills the datagrid(used telerik's Radgrid) in datagrid i have the option to select individual rows. when select linkbutton is clicked records are retrieved and the text is placed in respected text boxes (on main page) At first i didn't use update panel which resulted whole page being refreshed at every click on popup.everything other was fine.Data was being retrieved, filled in textboxes, inserted, deleted etcBut now when i am using updatepanel to avoid pagerefresh, select link isn't working i.e nothing is happening if i click on select link in grid.. popup is not disappearing also. \[code\]<asp:UpdatePanel runat="server" id="up1"><ContentTemplate><telerik:RadGrid ID="GridView1" runat="server" GridLines="None" AutoGenerateColumns="False" style="margin-top: 11px" BackColor="White" BorderColor="White" Skin="WebBlue" BorderStyle="Ridge" BorderWidth="2px" CellPadding="3" Width="100%" onselectedindexchanged="GridView1_SelectedIndexChanged" > <GroupingSettings CaseSensitive="false" /> <ClientSettings> <Scrolling AllowScroll="True" UseStaticHeaders="True" /> </ClientSettings> <MasterTableView TableLayout="Fixed"> <Columns > <telerik:GridBoundColumn DataField="name" HeaderStyle-Width="110px" HeaderText="Name" ShowFilterIcon="false" SortExpression="name" UniqueName="Name"><HeaderStyle Width="110px" /></telerik:GridBoundColumn> <telerik:GridBoundColumn DataField="Address" HeaderStyle-Width="110px" HeaderText="address" ShowFilterIcon="false" SortExpression="address" UniqueName="address"><HeaderStyle Width="110px" /></telerik:GridBoundColumn><telerik:GridBoundColumn DataField="telephone" HeaderStyle-Width="115px" HeaderText="telephone" SortExpression="telephone" UniqueName="telephone"><HeaderStyle Width="115px" /></telerik:GridBoundColumn><telerik:GridButtonColumn CommandName="Select" HeaderText="Select Row" Text="Select" UniqueName="Select"></telerik:GridButtonColumn></Columns><PagerStyle Mode="NextPrevAndNumeric" /></MasterTableView></telerik:RadGrid> </ContentTemplate> <Triggers> <asp:AsyncPostBackTrigger ControlID="Btok" EventName="click" /> <asp:AsyncPostBackTrigger ControlID="GridView1" EventName="SelectedIndexChanged" /> </Triggers>\[/code\]/////////////////////\[code\] </asp:UpdatePanel><ajaxToolkit:ModalPopupExtender ID="modelPopupExtender1" CancelControlID="Btcancel" PopupControlID="Panel1" TargetControlID="Button1" Drag="true" BackgroundCssClass="ModelPopupBG" runat="server" DropShadow="True" > </ajaxToolkit:ModalPopupExtender> <ajaxToolkitragPanelExtender ID="dragPanelExtender" runat="server" TargetControlID="Panel1" DragHandleID="Panel1" ></ajaxToolkitragPanelExtender>\[/code\]p.s this is my page_load().. application runs without any definition of it but whatshould i add in it .. to make things right ??\[code\]protected void Page_Load(object sender, EventArgs e) { Page.Validate(); if (!IsPostBack) { } } \[/code\]Any clue what i am doing wrong ? please help me out
