I really want a CheckBox to be the Display Control in Column #1 of a Grid.

I ran "C:\HMG.3.4.4\Samples\Controls\Grid\Grid_CheckBoxes\Demo.prg"
Here Column #1's display gives what I want:

: GridCheckbox.PNG (5.28 KiB) Viewed 4061 times

However this does not show in my Grid. My Column #1's has no CheckBox:[/i]

: No_Checkbox.PNG (2.1 KiB) Viewed 4061 times

Important:
My Grid's Column Controls Array: {{"CHECKBOX"},{'TEXTBOX'}, {'TEXTBOX'},.....}
My Column #1's control source is a .DBF field of type LOGICAL.
My .FRM code is created using the HMG IDE.

NOTE: I have read the following relevant forum post:

I want to redefine piece of code and use Grid with CheckBoxItems.
I'm using IDE to design form. But, I can't see possibility for grid with CheckBoxItems. Am I wrong?
No, you can´t, but you can enable checkboxes at window loading time

Thus: My code contains this (from salamandra):

Code: Select all

....
LOAD window DataBrowse
// https://www.hmgforum.com/viewtopic.php?f=5&t=6467&p=62213&hilit=CheckBoxEnabled#p62213
//                                              /* Enable checkboxes here */
DataBrowse.BrowseStates.CheckBoxEnabled := .T.	/* Form_1.Grid_1.CheckBoxEnabled := .T. */
....

QUESTION: Can anyone please help me with I do not understand about a CheckBox in a Grid?
Thank you!

Look \SAMPLES\Controls\Grid\GRID_36\demo.prg

it doesn't seem to work as we would expect

Thank you dragancesu, I appreciate your kind response.

As you note ...\SAMPLES\Controls\Grid\GRID_36\Demo.PRG (using demo.hbp via the IDE)
displays differently than ... \SAMPLES\Controls\Grid\Grid_CheckBox\Demo.PRG.

I have looked at both Demo.PRG program samples (and others) but still do not
understand what might allow a simple CheckBox in my Grid.

Any help would be appreciated. Thank you,
Red2

Hi red2

I use this grid with simple checkbox:

Code: Select all

DEFINE GRID Grid_Agenda 
   ROW 10
   COL 10
   WIDTH  1565
   HEIGHT 650
   HEADERS {"Weg", "Nr", 'Dag'   } 
   WIDTHS  {50,     30,   90 }
   CELLNAVIGATION TRUE
   COLUMNWHEN     {  {|| TRUE },  { || FALSE }, {|| FALSE }} 
   JUSTIFY {GRID_JTFY_LEFT, GRID_JTFY_LEFT, GRID_JTFY_LEFT } 
   COLUMNCONTROLS {   { 'CHECKBOX', 'Yes' , 'No' }, ; // DELETION
                      { 'TEXTBOX',  'CHARACTER'}, ;	
                      { 'TEXTBOX',  'CHARACTER'} }		
   ALLOWEDIT      TRUE
   ITEMS aGrid_Agenda

END GRID

Grid filled up after screen is activated!
Maybe this can help, succes, Serge

Hi Serge,

Thank you. I'll have a look at your example code.
I really appreciate all of your kind guidance!

Hi Serge,

I compared your sample code to mine (an IDE created .FRM) and found nothing significant to change.
Unfortunately Column #1's cell still does not display a CheckBox.

My Grid's Control Source is a .DBF table, not an Array.
I wonder if the kind of a Grid's Control Source somehow changes the column's Display.
Does your Grid's Control Source display via an Array or a .DBF?

Question: Can you rule in or rule out whether the kind of Control Source prevents the display of my CheckBox control?

Again, thank you for your valuable guidance.

hi Red,,

have you use

Code: Select all

   SET BROWSESYNC ON                                                  // sync BROWSE with DBF

Red,

In my ARRAY example first column (which is the checkbox) is in my ARRAY .T. or .F.

Code: Select all

ADD ITEM	 {.F., ALLTRIM(STR(nNR,4,0)), dag1}

This has to match in your DBF. If first DBF field is CHAR then no checkbox will be in the grid.
I think this the cause.

Hi All, Thank you for your help. I really appreciate all the kind help here.

Jimmy: I cannot find BROWSESYNC in a Grid control. The control in this case is a Grid.
My purpose in choosing a Grid control over a Browse control is to allow a CheckBox in Column #1.

Serge: The first Column's control source is a .DBF field of type LOGICAL. We can rule this out.

QUESTION: What else am I missing here?

Thanks again,
Red2

Try to change ColumnControls[1] to NIL
don't set it as {"CHECKBOX"}
