Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

    AJAX CallBack in grid (Rookie question)

    Hello, I have a grid component that i would like to add an xbasic function to. There is a button in the grid list that performs the call back. I have declared my xbasic function but I am having trouble adding column value to one of my arguments. I know in a dialog component I would use for example "e.dataSubmitted.PK_MAIN_ID" to get a pointer for the value I would like to set the arg to, what is the equivalent for a grid?

    Ive tried using "args.set("arg1",e.rowData.data("PK_MAIN_ID"))" but I get an error that states "Property not found e.rowData subelement not found"

    Im sure the answer is simple but i just cant see it right now, Please help, thank you.

    This is what I'm using in my grid xbasic: args.set("Some_Arg_Name",e._currentRowDataNew.My_Control_Here)

    Try this...

    Code:
    args.set("arg1",e._currentRowDataNew.PK_MAIN_ID)
    By the way: The argument can be named anything. It doesn't have to be "arg1". Just FYI.

      Thanks for the reply Mike, but I still get the same error Property not found e._currentRowDataNew.PK_MAIN_ID subelement not found

      Code:
      'MARK LTS STUDENT to look-up Table
      function MarkStudent as c (e as p)
      	debug(1)
      	dim cn as sql::Connection
      	dim args as sql::Arguments
      	dim sqlINSERT as c
      		
      	args.set("arg1", e._currentRowDataNew.PK_MAIN_ID)
      	args.set("arg2", "MAIN")
      	args.set("arg3", a5ws_getcurrentuser())
      			
      	flag = cn.open("::Name::JAC")
      		If flag = .f. then
      			MarkStudent = "alert('Could Not Establish Connection');"
      		else
      			sqlINSERT = "INSERT INTO marked (RECORD_ID, TABLE_NAME, STAFF_NAME) VALUES (:arg1, :arg2, :arg3)"
      			flag = cn.Execute(sqlINSERT, args)
      				If flag = .f. then
      					MarkStudent = "alert('Oops! Record Could Not Be Marked! " + js_escape(cn.CallResult.text) + "');"
      				else
      					MarkStudent = "alert('Record was Marked.');"
      				end if
      		end if
      	cn.Close()
      
      end function

        is this during an insert of a new record?

          No, this grid shows students (read-only). My users need to isolate specific students, what I was creating is a search grid to find students, then using a button in the grid to do an ajax callback to insert values into a separate table.

          *Essentially, I am trying to "mark" students the way the native alpha dbf tables allow for desktop.

          This works as i expect in a ux component, but I want this function to work in the grid so the user does not need to open a ux component in order to "mark" a student.
