asp.net - radGrid control not showing data in aspx page -
i have asp.net application (created previous developer) uses radgrid control display data. however, radgrid not show data if there on page. radgrid works fine remove updatepanel. if remove updatepanel, radcombobox makes whole page submit (instead of using ajax).
is there anyway make radgrid , work together?
<asp:updatepanel id="upnlfilter" runat="server" updatemode="conditional"> <contenttemplate> <span class="subheader">vtrip log search: </span> <asp:panel id="panel1" runat="server" bordercolor="#e3b391" borderstyle="solid" borderwidth="1" width="994px"> <div style="height:10px; width:994px"> </div> <table style="width: 974px; margin: 10px" border="0"> <tr> <td width="200px"> <telerik:radcombobox id="driverdd" runat="server" height="120px" width="180px" dropdownwidth="180px" emptymessage="choose driver" highlighttemplateditems="true" autopostback="true" appenddatabounditems="true" onselectedindexchanged="driverdd_selectedindexchanged" > </telerik:radcombobox> </td> <td width="220px"> <asp:textboxwatermarkextender id="textboxwatermarkextender1" runat="server" targetcontrolid="txtdos" watermarktext="select today or previous day" watermarkcssclass="watermarked"> </asp:textboxwatermarkextender> <asp:textbox id="txtdos" runat="server" width="200px" enableviewstate="true" cssclass="settextbox" height="20px" bordercolor="#cccccc" borderstyle="solid" borderwidth="1px"></asp:textbox> <asp:calendarextender id="txtdos_calendarextender" runat="server" enabled="true" targetcontrolid="txtdos"> </asp:calendarextender> </td> <td style="width:350px"> </td> </tr> </table> </asp:panel> </contenttemplate> </asp:updatepanel> <br/> <telerik:radgrid id="radgrid1" onsortcommand="radgrid1_sortcommand" onpageindexchanged="radgrid1_pageindexchanged" width="99%" height="181px" onpagesizechanged="radgrid1_pagesizechanged" allowsorting="true" pagesize="5" allowpaging="true" allowmultirowselection="true" runat="server" gridlines="none" autogeneratecolumns="false"> <mastertableview height="100px" width="100%" summary="radgrid table"> <commanditemsettings exporttopdftext="export pdf" /> <rowindicatorcolumn filtercontrolalttext="filter rowindicator column" visible="true"> </rowindicatorcolumn> <expandcollapsecolumn filtercontrolalttext="filter expandcolumn column" visible="true"> </expandcollapsecolumn> <columns> <telerik:gridboundcolumn datafield="tripid" headertext="trip id" sortexpression="tripid" uniquename="tripid" sortascimageurl="sortasc.gif" sortdescimageurl="sortdesc.gif"> </telerik:gridboundcolumn> <telerik:gridboundcolumn datafield="membername" headertext="member name" sortexpression="membername" uniquename="membername" sortascimageurl="sortasc.gif" sortdescimageurl="sortdesc.gif"> </telerik:gridboundcolumn> <telerik:gridboundcolumn datafield="vehicletype" headertext="vehicle type" sortexpression="vehicletype" uniquename="vehicletype" sortascimageurl="sortasc.gif" sortdescimageurl="sortdesc.gif"> </telerik:gridboundcolumn> <telerik:gridboundcolumn datafield="status" headertext="status" sortexpression="status" uniquename="status" sortascimageurl="sortasc.gif" sortdescimageurl="sortdesc.gif"> </telerik:gridboundcolumn> </columns> <editformsettings> <editcolumn filtercontrolalttext="filter editcommandcolumn column"> </editcolumn> </editformsettings> <pagerstyle pagesizecontroltype="radcombobox" /> </mastertableview> <pagerstyle mode="nextprevandnumeric"></pagerstyle> <filtermenu enableimagesprites="false"> </filtermenu> </telerik:radgrid> code behind: (populate grid using grid - simple data binding)
private void loaddata() { if (session["tripmaster"] != null) { radgrid1.datasource = session["tripmaster"]; radgrid1.databind(); } }
could move radgrid inside updatepanel , try again?
<asp:updatepanel id="upnlfilter" runat="server" updatemode="conditional"> <contenttemplate> <span class="subheader">vtrip log search: </span> <asp:panel .... </asp:panel> <br/> <telerik:radgrid .... </telerik:radgrid> </contenttemplate> </asp:updatepanel>
