For Visual Basic how to create an alert if a user only selects a month but not a year or offense, then clicks 'submit'? There should be an error thrown and an alert on the screen, or along the side or bottom of a combobox; letting the user know they need to compete the form to submit.

Here's my use case:
I'd like to display the information about something first using django_tables2, with a button on the top right corner called "Edit", once a user hits "Edit", at the bottom of the table, display a button called "Add New Record", and once the user clicks that button, a bunch of input fields pop up to let users enter values for each field, also the user could continue to click "Add new Record" to keep adding new.
How can I achieve this in Django?
I've read a lot of examples on stackoverflow but didn't find anything tailored to this particular case.
Thanks a lot.
Let's dive right into listing out what you want to do and the requirements you'll need to do so.
You basically want to toggle hiding and showing some functionality for this web page. This is easily accomplished by including the "Edit" button, "Add New Record" button, and popup (most likely in its own <div> somewhere in the page). So the "Edit" button will have the display set to something, be it inline, block, etc., while the "Add New Record" and popup would have a display of "none" or however it is you wish to hide it.
You've got the stuff set up and ready to go but now you need to show it when you click the "Edit" button. This is generally accomplished through Javascript. Just find the "Add New Record" button and switch the visibility.
When you click on the "Add" button you want to display a popup. This can be done in a variety of ways with different libraries. One of my personal favorites is using jquery's blockUI. Why? It doesn't allow the user to click anywhere except in the popup so it's a quick way to handle users trying to reach outside the scope of the popup.
So you've got all the new rows added and you are done editing. Maybe you have a "Save" button or something like that where you can click. When you do, you'll want to push all those new rows you just added to the database. Django handles this well and you could do something like include the new rows in part of the POST request or however you care to implement this solution.
So there's a bit of work ahead of you to get this page up and running with the exact functionality you need but hopefully this starts steering you in the right direction of where you need to go.
We have a rendering listing the selected items in a TreeSelect in the current item. In our case we call them "Tags" (1)
We have added a Field Editor Button to the component to let the editor change selected items. (2) (As described on for example Adding a custom component)
When an editor clicks (2) the editor window (3) it is opened in a dialog. The editor may select different items(called tags in our case) using the TreeSelect.
When the editor presses the ok-button (4) the values are set.
Now to the problem:
The values are actually set as they get stored when the editor presses the Save button but we want our list on the page (1) to immediately reflect the set items when the editor presses the ok-button (4), i.e. before having to actually save the whole item.
How do we achieve that?
(I am in contacts with Sitecore support but so far I have not gotten any answers...)
Update
After a lot of conversation with the support we still have no useful solution.
We tried turning it into a field renderer displaying the links.
What worked was:
The field do get updated when you have edited it in the popup field editor. (but...)
It looks good the first time when page is loaded.
You can make a WebEdit button with commands to edit the field and add it as Custom button to the field (register <command name="webedit:fieldeditor" type="Sitecore.Shell.Applications.WebEdit.Commands.FieldEditor, Sitecore.Client"/> and set Click on the button to webedit:fieldeditor(command={3473DDA1-2983-493C-AF7A-054C75AA7AD3},fields=NameOfField where the guid points to itelf and an "Icon" is set on it.)
What didn't work was:
The field get updated by the raw value, not what I want to display. Server code is involved, but not in the rendering of html-code.
When I want to edit the value in the field editor, the value sent to the field editor is not the raw value but what actually is displayed on the page. (I guess this can be solved somehow)
The issue to the support turned into a feature request to let the server be involved in rendering the field, not just sending a new value to the JavaScript updating it. The server does the first rendering so when it already is involved in updating, it should be allowed to do the rendering the following times too.
We have decided to not spend more time on this right now (we have other things to do too.) and have a bad editor experience as the field not get updated until the editor actually saves the item.
Still we have no suitable solution for this issue. If you want to keep working on it and want a reference to my issue it is 439059.
This may not be useful here. I've done this in normal sites, but not in Sitecore. But, here's one possibility....
This is a situation where you would pass a callback function to the child popup window. This callback will cause the caller / parent window to re-read/re-load the information that was just updated by the child.
Example:
User presses (2) to open Editor Window(3) (Editor window is opened and the Callback function is passed as a parameter)
User presses "OK" button (4). The "OK" button event handler updates the changes, then calls the Callback function which re-loads the now updated information, and closes the popup window.
Once the popup closes, the parent window now displays the information that the popup/editor just updated.
This takes some client side javascript (jquery) development but it is quite do-able normally.
I am trying to Incorporate a javascript validation on an application in apex.
Basically, what should happen is that the validation should run if i click on a textfield or another Item type. I want to the validation to runs without me having to click on a submit or save button.
For an example if I was filling out a form, I want to validation straight after the user click from "FirstName" field to "LastName" and each individual field will have it own validation.
The reason why I want to do this is because I have an application which takes about 15-30 minutes to fill out and sometimes after you spend all those mins filling it out and click on save or create. you get a long list of validation errors. To avoid this I want to use javascript/Ajax to do a validation which validate individual fields straight after you click from one field to another.
I have a feeling it can be done but i dont know how. Please point me on the right direction.
EDITED
for an example I have this validations
begin
if length(:p1_subject) >3 then
return false;
else
return true;
end if;
end;
This validation will only run when i click on the create button but I want it to work everything you click off and on the p1_subject field.
Hope I am making sense.
Thank you very much.
Can I modify the email that's created from a work item when I click the "send work item to microsoft outlook" button?
I've found a transform that allows you to alter the email related to an alert but (so far) not for this button? any ideas?
It is not possible to do that. It is on our backlog, but it will not be part of TFS vNext (TFS11)
Ewald Hofman (Program Manager TFS)
It is possible, with a small workaround.
Here's how:
1. Setup a Query that includes the fields you would like to show in the email. Filter it to include the criteria of your needs.
(In my case, I've chosen Team Project, ID, Title, Assigned To, State, History, Description. )
Run the query. It will likely give you a list of tasks/Work Items that apply to the query.
Right click on the one you wish to email, and select Send Selection to MS Outlook.
** 'Viola' - it will include the fields you've selected.
When the user clicks the OK or APPLY button on a property sheet and the program determines data on some page is invalid, how can I cause the page containing the error to be displayed along with a message box describing the error?
Currently the procedure doing the validation does the following while processing the PSN_APPLY notification.
MessageBox (hDlg, "Data must be positive!", "Error", MB_OK);
SetWindowLong (hDlg, DWL_MSGRESULT, PSNRET_INVALID);
This works ok if the page doing the validation (A) is currently displayed but if some other page (B) is being displayed, the message box appears with that page (B) being displayed, then when the message box is answered, the page with the validation error (A) is displayed. I thought about setting some flag so that when that page (A) gets the PSN_SETACTIVE notification it displays the message box but that seems kind of hokey.
Win32 API in c++, no MFC, no NET, nothing fancy.
I think the problem is in the design of your validation and it's presentation.
Am I right in thinking that you iterate through your property sheets, validate them and display a message box if something is awry? Because of course, what you have witnessed will happen, if I am on property page 3 and I wrote crap in to a field on property page 1.
The easiest solution is, when validating, note which property page the field in question is, and set that one active if the user has written crap in to one of your fields. This seems the fastest way possible.
Also, rather than spring up an annoying message box, reserve some room beneath the property pages to display a textual (red or otherwise) warning as to why, and then change to the appropriate property page, and highlight the offending control. Your validation routine can do this nice and easily as it loops through.
Even better, don't stop at the first error. One thing I HATE is correcting one field that I think is the only issue, only to be told every time I hit "OK" or "SUBMIT" that there's something else I missed.
I seriously think you should consider going the extra mile here... loop through ALL controls, and add all invalid ones to a list. Then change each offending control's background colour, tab colour etc... Then the user can work through and correct, no matter how many errors he or she made.
