How to control user input to a Net Grid cell with value list?

Viet Anh Le

Hi,

Anyone knows how we can control the user input to a Net Grid cell with value list?

I have a value list set to a cell where user can select option from the drop-down list. But it is still possible to enter any value into that cell, which is what I don't want (see snapshot below)

I know that the entered value will not be accepted if it is not the same as what I have in the value list, but I just don't want the users to get confused that they can enter value into the cell instead of selecting from the value list.

So I just want to know whether we can disable the manual input, or we have a way to check the input value against the value list. I can check that if I know which value list is set to the cell (I have different value lists set to different cells), but I can't find any method in the Net Grid API which helps to get that.

Any advice would be appreciated.

Regards,

Anh

  • Hi, you can use BeforeCellUpdate event.

    For example:

    !this.gridParams.AddEventHandler('BeforeCellUpdate', !this, 'OnBeforeCellUpdate')


define method .OnBeforeCellUpdate(!args is ARRAY)
    --Array[0] is the new value the cell is to be updated to
    --Array[1] is the row index of the cell
    --Array[2] is the column key of the cell
    --Array[3] is the band/datatable name
    --Array[4] is a true flag, used for other pml variables to signify a change is about to occur
    --Array[5] is an empty string, normally used for storing old values about to be changed
endmethod

    Hi,

    Yes, I know this. But my question is how to know which value list is set to which cell (I have different value lists set to different cells). I used a workaround to do that, but just wonder if there is any Net method which can quickly get the value list set to the cell.
