SYMPTOMS
In a grid, when you try to edit a column that doesn't have a control source, the computer beeps and the text is not entered. You might expect that the grid would accept data.



CAUSE
This is the correct behavior for columns that don't have a ControlSource set. If you set the ControlSource, the column is editable. As the code below demonstrates, a table defined with only two fields as a control source for the grid disallows the additional column a place to store the new information being entered when the button's click procedure is run.



WORKAROUND
Create a custom grid class with an Init procedure to alter the table or ControlSource to allow the user to create and store new data by passing the optional "init1,init2" parameter used with the addobject function.



STATUS
This behavior is by design.



Steps to Reproduce Behavior
Run the following code: CREATE TABLE table1 ; (col1 C(15), col2 c(15)) append blank replace col1 with 'Row(1) Col(1)' replace col2 with 'Row(1) Col(2)' append blank replace col1 with 'Row(2) Col(1)' replace col2 with 'Row(2) Col(2)' append blank replace col1 with 'Row(3) Col(1)' replace col2 with 'Row(3) Col(2)' append blank replace col1 with 'Row(4) Col(1)' replace col2 with 'Row(4) Col(2)' append blank replace col1 with 'Row(5) Col(1)' replace col2 with 'Row(5) Col(2)' skip - 5

use table1

public x x = create("f1") x.show

define class f1 as form add object grid1 as grid with ; forecolor = rgb(255,0,0);

add object b1 as commandbutton with ; fontsize = 8, ; caption = 'AddColumn', ; top = 200

add object l1 as label with ; caption = 'Clicking this button should add a Column.', ; fontsize = 8, ; autosize = .T., ; top = 220 proc b1.click x.grid1.addcolumn x.grid1.column3.addobject('text','textbox') x.grid1.column3.currentcontrol = 'text1' x.grid1.column3.text1.visible = .t.    x.refresh endproc enddefine


 * Click the AddColumn button.
 * Click in one of the blank cells and begin typing.
