Hi,
I am binding a valuelist to my ultrawingrid as shown in the attached sample. the value list items can change based on the value of the status column.
click the mouse on the cell on the 3rd column
1. when i change the value in the value list 1st row the cell updates properly
2. when i change the value in the value list 2nd row the cell updates properly
3. when i try to change the value in value list in 3rd row it changes the cell value of the 1st row.
similarly if we edit multiple rows.. all the previous edited rows get affected once we move the move to a new row
Please help me in resolving this.
thank you.
Changing the ValueList for the column will not work correctly, because when the grid paints a cell, it needs the ValueList to convert the DataValue from the cell into the matching DisplayText on the list - and if the list is not there, it cannot do it.
What you should do here is set the ValueList on the cell instead of on the column.
Or, you could check out this article which shows how to do this with a single list that uses filtering.

By the way... your sample has some pretty strange code in it. For example, this line of code is going in circles:
UltraGrid1.ActiveCell.Column.Header.Column.ValueList = BuildStatusList(UltraGrid1.ActiveRow.Cells("Status").Value.ToString)
You are getting the Column property on the cell here, then getting the Header, and then going back to the column. These two objects are exactly the same:
UltraGrid1.ActiveCell.Column = UltraGrid1.ActiveCell.Column.Header.Column
Anyway, what you really should be doing is this:
UltraGrid1.ActiveCell.ValueList = BuildStatusList(UltraGrid1.ActiveRow.Cells("Status").Value.ToString)
Hi Mike,
Thanks for the reply and the suggestion.
I understand what you are saying. But if i bind the value list in the UltraGrid_IntializeLayout i will see the dropdown visible everytime the mouse hovers over any cell in status column. That is the reason i am setting cell activation to NoEdit in UltraGrid_IntializeLayout and then making it AllowEdit in UltraGrid1_MouseUp. my requirement was to show the dropdown only when the user clicks on the cell to change the status.
I have tried setting the value list on the Cell. Even then when i continously change the status on the cells on different rows, the previously edited cells are set with the value id's like 0,10,20..
I have also tried this using UltraGrid1_AfterCellUpdate instead of UltraGrid1_AfterCellListCloseUp but i am facing the same issue.
can you replicate this issue at your end? Please suggest
Thank you.
