One can use the following code in the created event of a screen to select the first item in a visual collection bound to a Table control (or any list control - code based on an old example from Huy): myapp.MyScreen.created = function (screen) { var visualCollection = screen.Orders; function selectFirst() { var first = visualCollection.data[0]; visualCollection.selectedItem = (first) ? first : null; } if (visualCollection.state === msls.VisualCollection.State.idle) { // If the visual collection is already loaded, try selecting the first item. selectFirst(); } else { // Otherwise, listen to the state change event and when the visual collection is loaded, // select the first item. Also remove the event handler because this should only happen once. function onVisualCollectionStateChanged() { if (visualCollection.state === msls.VisualCollection.State.idle) { visualCollection.removeChangeListener("state",

I have a modal dialog screen that needs to be larger than the default in both height and width. I can use one of the Group control post-render methods on that dialog to set the height and Width, but I cannot seem to shift the dialog up by changing the top-margin of the dialog. I want the dialog to move up due to the fact that it is so large. This is the code in the Group control post-render method: myapp.MyLargePicker.SomeGroupControl_postRender = function (element, contentItem) { // set dialog width to 1200px $('div[class~="msls-dialog-frame"]').css('maxWidth', '1200px'); // set dialog height to 800px $('div[class~="msls-dialog-inner-frame"]').css('height', '800px'); // move the dialog up (it moves up and then down again??) setTimeout(function () { $('div[class~="msls-dialog-frame"]').css('margin-top', '10px'); }); }; Setting the margin-top above needs to be set inside the timeout() function otherwise it

I have a table containing FirstName and LastName and am trying to project that as LastName, FirstName in a Table. I add a local property FullName in the client and add post render code: myapp.BrowseCustomerItems.FullName_postRender = function (element, contentItem) { function fullName() { return contentItem.data.LastName + ", " + contentItem.data.FirstName; } contentItem.dataBind("screen.ContentItems.FullName", fullName) }; The dataBind is not working.  I have tried using "screen.ContentItems.CustomerItems.FullName" as well. I hope the screen shot from VS2013 below will help.

Hi guys. Ive got simple grid view table with some fields open for edit (SQL Server). And I use code behind event to assign username and date time to edited strings: Private Sub L2_***_Updating(entity As L2_***Item) Dim username As String = Me.Application.User.FullName entity.DtT = Now entity.user_id = username End Sub And this works almost fine, exept moment when you want to update table row which already has been updated. Subject transaction error appears. I believe this is happening becouse of difference between LS cache and SQL Server info. So I want to ask you guys how to work it out? For now I use stupid construction:
  myapp.onsavechanges = function (e) {
setTimeout(function () {
     window.location.reload(1);
   }, 1500);
};
 Probably, I should assign date and username before updating. Or update my table fields after changes saved. Or just make it to ignore transaction
