datatable defaultvalue changed programmatically

[nev]

my datatable column defaultvalue depends on what is displayed on a textbox. but i noticed that you can only set the defaultvalue once because when i set it again, the defaultvalue remains the same as what i set as a defaultvalue in the beginning.

how will i get this to work? i want the defaultvalue of my datatable to change to what is placed in my textbox.

you have to issue the Update command if you want to save any changes!

Is this a windows form or asp .net application?

it doesn't work

the defaultvalue still remains unchanged

dtt.column.defa ultvalue = "hello" 'this is ok

when i add new in the datagridview, the column automatically displays "hello" as the default value.

then i do another dtt.column.defa ultvalue = "world" 'this is not ok

when i add new in the datagridview, the column still automatically displays "hello" as the default value and not "world".

how do?

are you setting the default values programatically or in the design mode (ie in the dataset file)

if you are doing programatically please make sure that you remove all instances where you set the default value to "hello"
