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.

    Sprucing up the Grid Alphabet Button Search

    I was demoing the Grid's Alphabet button search and thought I'd try to disable those Alphabet buttons that would produce no records in a search. This code will do this and you can change the style of the button.

    There's probably better events to use than I did, but I just wanted to know if it were easily possible... and kinda just get it done. I'm searching against is a SQL Server Join statement of two tables just a bit over 11,000 records.
    I've read about better methods for searches against large record numbers, but this will do for now. There isn't any error checking in the Xbasic yet.

    First, in your Grid, in the Server-side event, OnAfterExistingRowRender: Here we're going after the sql tables and returning DISTINCT LEFT(fieldname,1)... so... should be a maximum of 1 row for each letter of the Alphabet plus numbers After we get the results, turn the resultset into a CRLF string with ToString, and then turn the CRLF string into a comma delimited string. Finally return the string to Javascript in a global variable. This is actually the reason I used this event... because I can return Javascript and therefore create the Javascript variable.

    Code:
    dim cn as sql::Connection
    dim args as sql::Arguments
    dim rs as sql::ResultSet
    dim currUser as C
    
    sql = "SELECT DISTINCT LEFT(Customers.CompanyName,1) as alphaCmpyName FROM WorkOrders WorkOrders INNER JOIN Customers Customers ON  WorkOrders.CustomerId = Customers.CustomerID ORDER BY alphaCmpyName"
    
    cn.open("::name::your_connection_name_goes_here")
    cn.PortableSQLEnabled = .t.
    
    dim cmpyLetters as c = ""
    
    cn.Execute(sql)
    rs = cn.ResultSet
    cmpyLetters = crlf_to_comma(rs.ToString())
    
    cn.FreeResult()
    cn.close()
    
    e.javascript = "searchLetters = '" + cmpyLetters + "';"

    Next, in the Client-side event, onGridRenderComplete: Here we're grabbing the Alphabetbuttons DIV, and then grabbing all the specific buttons themselves, under the DIV. Next... since we have our "searchLetters" variable containing all our valid search Letters, compare each of the Alphabetbutton letters to our valid search Letters. If there's a hit, turn the letter Green. No hit... disable it and turn it red.

    Code:
    //The variable 'searchLetters' comes from the Server-side event OnAfterExistingRowsRender
    var myDiv = document.getElementById( "{grid.componentname}.GRID_PART.ALPHABETBUTTONS" );
    var inputArr = myDiv.getElementsByTagName( "button" );
    for (var i = 0; i < inputArr.length; i++)
    	{
    	var str=searchLetters;
    	var n=str.search(inputArr[i].innerHTML);
    	if (n == -1)
    		{
    		$(inputArr[i]).disabled = true;
    		$(inputArr[i]).style.color = 'red';
    		}
    	else
    		{
    		$(inputArr[i]).style.color = 'green';		
    		}
    	}
    And Finally... take the exact same Javascript code above and put it into the Client-side event afterAlphabetButtonSearch because after your search everything goes back to it's original state.

    That's it. I just love this stuff... what can't you do in Alpha 5!

    Hi David,

    Thank you for sharing this and thank you for all of the help you have provided to me over the years allowing me to say this too.

      Re: Sprucing up the Grid Alphabet Button Search

      I made a little modification to include the All button.
      Code:
      dim cn as sql::Connection
      dim args as sql::Arguments
      dim rs as sql::ResultSet
      dim currUser as C
      
      sql = "SELECT DISTINCT LEFT(Customers.CompanyName,1) as alphaCmpyName FROM WorkOrders WorkOrders INNER JOIN Customers Customers ON  WorkOrders.CustomerId = Customers.CustomerID ORDER BY alphaCmpyName"
      
      cn.open("::name::your_connection_name_goes_here")
      cn.PortableSQLEnabled = .t.
      
      dim cmpyLetters as c = ""
      
      cn.Execute(sql)
      rs = cn.ResultSet
      cmpyLetters = crlf_to_comma(rs.ToString())
      [COLOR="#FF0000"]cmpyLetters = cmpyLetters  + ",All"[/COLOR]
      cn.FreeResult()
      cn.close()
      
      e.javascript = "searchLetters = '" + cmpyLetters + "';"
      I have also found that if you have a search part you have to make an additional mod. I found that putting the client side code in the AfterAjaxCallbackComplete client side event that everything works OK and I have had no issues.

        Excellent... thanks Frank. I have a search part, but I hadn't tested it yet... I was wondering how much the two would affect each other. Thanks for the "All" too... I guess we need that :)
