c# - Why isn't the UpdatePanel found to update the data -
i have following code in asp.net page:
<asp:updatepanel runat="server" clientidmode="static" updatemode="conditional" id="upclickshowtask"> <contenttemplate> <asp:linkbutton id="lbshowtask" cssclass="btnexport" clientidmode="static" runat="server" text="generate tasks" onclick="btnfilter_click"></asp:linkbutton> </contenttemplate> </asp:updatepanel> <asp:panel id="pagetab8" clientidmode="static" runat="server"> <asp:panel id="democli" clientidmode="static" runat="server" borderwidth="2" bordercolor="#ff0000"> <asp:updatepanel id="upgentaskcli" runat="server" updatemode="conditional" clientidmode="static"> <contenttemplate> client: <asp:label id="lblcli" clientidmode="static" runat="server" text=""></asp:label> <br /> onboarding date: <asp:label id="lblclidate" clientidmode="static" runat="server" text=""></asp:label> <br /> contact information: <asp:label id="lblclicont" clientidmode="static" runat="server" text=""></asp:label> <br /> notes: <asp:label id="lblclinotes" runat="server" clientidmode="static" text=""></asp:label> <br /> </contenttemplate> </asp:updatepanel> </asp:panel> </asp:panel> the code-behind:

lblcli.text = mydataset.tables[0].rows[0]["client"].tostring(); lblclidate.text = mydataset.tables[0].rows[0]["onboarding date"].tostring(); lblclicont.text = mydataset.tables[0].rows[0]["contact information"].tostring(); lblclinotes.text = mydataset.tables[0].rows[0]["notes"].tostring(); and hovering mouse on them, displays text data upgentaskcli not updating show data.
i receive error:
0x800a139e - microsoft jscript runtime error: sys.invalidoperationexception: not find updatepanel id 'upgentaskcli'. if being updated dynamically must inside updatepanel. how resolve issue?
since js visibilty error, try put update panel inside update panel this:
//this how view should like
<asp:updatepanel id="pnlparent" runat="server" updatemode="conditional"> <contenttemplate> <asp:updatepanel id="upgentaskcli" runat="server" updatemode="conditional" clientidmode="static"> <contenttemplate> client: <asp:label id="lblcli" clientidmode="static" runat="server" text=""></asp:label> <br /> onboarding date: <asp:label id="lblclidate" clientidmode="static" runat="server" text=""></asp:label> <br /> contact information: <asp:label id="lblclicont" clientidmode="static" runat="server" text=""></asp:label> <br /> notes: <asp:label id="lblclinotes" runat="server" clientidmode="static" text=""></asp:label> <br /> </contenttemplate> </asp:updatepanel> </contenttemplate> </updatepanel> so in code behind following :
protected void page_load(object sender, eventargs e) { if (!ispostback) { scriptmanager.registerstartupscript (this, typeof(page), "updatemsg", "$(document).ready(function(){$('#upgentaskcli').hide();});", true); } } //and in button logic add following line in if clause :
protected void btnfilter_click(object sender, eventargs e) { if (ddlcli.selectedindex > 0) { try { query = querycli + " c.attr2815 = '" + ddlcli.selectedvalue + "'"; // create data adapter sqldataadapter da = new sqldataadapter(query, conn); // query database , return result datatable dataset mydataset = new dataset(); da.fill(mydataset); lblcli.text = mydataset.tables[0].rows[0]["client"].tostring(); lblclidate.text = mydataset.tables[0].rows[0]["onboarding date"].tostring(); lblclicont.text = mydataset.tables[0].rows[0]["contact information"].tostring(); lblclinotes.text = mydataset.tables[0].rows[0]["notes"].tostring(); } catch (exception ex) { string error = ex.message; } scriptmanager.registerclientscriptblock (this, typeof(system.web.ui.page), "myjsfunction", "$('#upgentaskcli').toggle();", true); } //it should work
