javascript - Display Bootstrap ModalPopup on Click on ASP Button without using Modalpopupextender -


i trying call javascript function on click event of asp button , function trying click html button invoke modal pop.

status: able file html button's click event , run alertbox in not modalpopup. able open modalpopup directly clicking html code.

code: //code

protected void button1_click(object sender, eventargs e) {     button btn = (button)sender;     repeateritem ri = (repeateritem)btn.parent;     label id = (label)ri.findcontrol("payid");     add_account_head_1.headid_property = id.text;      update1.update();      string script = "showpop();";     scriptmanager.registerstartupscript(this, gettype(),                           "servercontrolscript", script, true);  }

in body section

 $("#btn1").click(function () {          //     alert('this has been clicked');         $("#mymodal").modal('show');       });

in head section

     function showpop() {              var button = document.getelementbyid('btn1');             button.click();         };

you can invoke modal.show directly server side. make sure #mymodal correct selector. can verify id dev tools.

protected void button1_click(object sender, eventargs e) {     button btn = (button)sender;     repeateritem ri = (repeateritem)btn.parent;     label id = (label)ri.findcontrol("payid");     add_account_head_1.headid_property = id.text;      update1.update();      string script = "showpop();";     scriptmanager.registerstartupscript(this, gettype(),                           "servercontrolscript", "$('#mymodal').modal('show');", true);  }

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
