c# - How to preserve order in Gridview -

-

in program (asp.net, c#) using gridview show data. gets data following query.

select * nametable nameid in (4,3,1,22,15,8,9,5,7)

but problem gridview showing data in ascending sort order of nameid (1,3,4,5,7,8,9,15,22). dont want data sorted, should show way mentioned in query (4,3,1,22,15,8,9,5,7)

here code

private void loadgridview() {     query = "select * nametable nameid in (4,3,1,22,15,8,9,5,7)"          dataset ds = sqlhelper.executedataset(commonsettings.constring, commandtype.text, query);         gridview1.datasource = ds;         gridview1.databind(); }

that pretty difficult code you've provided. doesn't have gridview, it's how data returned sql. sql won't order results way. you'd have specify explicit case in order by this:

query = "select * nametable nameid in (4,3,1,22,15,8,9,5,7) " +         "order case nameid when 4 0 " +                              "when 3 1 " +                              "when 1 2 " +                              "when 22 3 " +                              "when 15 4 " +                              "when 8 5 " +                              "when 9 6 " +                              "when 5 7 " +                              "when 7 8 end";

obviously very cumbersome. suggest try sorting column instead.

javascript - Image onload event not firing in firefox -

-
i'm creating image preloader. works fine in browsers except firefox (testing firefox 10.0). input array of images called image_list . these images appended dynamically body of document , load callback attached, calls function update_progress . code follows: $(image_list).each(function() { var x = $('<img />') .load(function() {update_progress(percent_loaded += step);}) .attr('src', this) .appendto('body') .css('display', 'none'); .each(function() { if(this.complete) update_progress(percent_loaded += step); }); }); in firefox, load callback , update_progress never called. yet exact same code works fine in chrome , other browsers i've tested. there way detect when image has loaded in firefox? i first check see whether image has height, checking height property. if (the_image.height > 0) { // image loaded (possibly cached) } if have cached ...

android - getbluetoothservice() called with no bluetoothmanagercallback -

-
i getting getbluetoothservice() called no bluetoothmanagercallback error in android application. i have no idea causing or bluetooth manager callbacks. can give me idea of causing problem or start looking. by reading android source code, seems warning cannot about. source code shows if call bluetoothsocket#connect(); then call bluetoothadapter.getdefaultadapter().getbluetoothservice(null); the key here, null parameter passes in above line. due this, there no callback, , bluetoothsocket class throw out warning. since warning, not think need it. https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothsocket.java line 306 https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothadapter.java line 1610
