Update: if you use the formatter as 'n' for number, it works fine...!
The data I am getting from the database is in the RAW format. For example, if I am tracking the price of the item, it will be 23.45343 . I need to display in the form of 23.45.
I also need to take care of the rounding the values. Also, adding ',' for every thousands e.g. 1,000,000.01 But I do not need currency specifier along with it. e.g. $. I can add formats such as c, d. But I need the currency specifier removed.
I also need to handle percentages, to show, 2.1 as 2.1%
Now, I can use 'p' to format it as %, but the problem here is the data I am getting from the DB is already in %. But the number doesnt have the % sign, which I need to add to the cells.
Is it possible to do that? If yes, how?
Another Update:
The datetime data I am getting from the database is like this: "Fri Sep 05 00:00:00 EDT 2008"
I need to convert it to MM/dd/yyyy format. I have tried using format strings like d,g,etc. But I am not able to format it. Is there any way where we can manually format the data of the column?
I'll really appreciate your help in this regards.
Thanks :)
I already had a post on this. But had many updates after that and hence posting it again.
I am using UltraGrid for my application. One of the columns' data which I am getting from the DB contains a % value. And, I need to display that as '% ' in the grid. e.g. 2.1 --> 2.1%. So, I can not use the formatter 'p' for this.
Moreover, for another column, I am getting the date as, 'Fri Sep 05 00:00:00 EDT 2008'. I tried using the formatters like 'd', 'g', but it is not working. Is there any way to format it such that, I can format the value in MM/dd/yyyy format?
What the grid does is take the Value of the cell and call ToString on it and pass in the Format you specified. So the formats you can use are not related to the grid, they are the format used by the data type you are using. For documentation on the formats, check out Microsoft's documentation:
Standard Numeric Format Strings
Custom Numeric Format Strings
If you can't get what you want using those, then the next option would be to format the values yourself. You could do this by hiding the real column and showing an unbound column. Or you could use a DataFilter.
The unbound column approach is easier, especially if the field is not editable - since you do not have to un-format it.
Kelly said:Is there a way to make it work so that the $ is left aligned and the amount is right aligned?
No, I don't believe this is possible with DotNet formatting. ToString just returns a string and it has no notion of the size of the area in which the string will be displayed. So it cannot control the alignment.
Thanks Mike,
Is using ValueBasedAppearance more effcient than using InitializeRow?
Thanks, Kelly
Hi Kelly,
No, they are probably about the same efficiency-wise. Assuming that you write your InitializeRow code efficiently. You might want to take a look at the WinGrid Performance Guide for some tips on that.
The real difference is that a ValueBasedApperance can be set up at Design-time without writing any code.
If you are going to do it at run-time, then InitializeRow is actually less code.
Thanks Mike
Hi
Same column with positive and negative values
i have to enter negative values only in a cell for the particular rows.
and then i have to enter positive values only in the cell for other rows.
is any option in ultragrid?
Hi,
You could apply different masks to cells in the same column using an editor. What you would do is place two UltraMaskEdit controls on the form with the grid. Then you set up the two control with different masks so that one allows negative numbers and the other does not.
Set the UseEditorMaskSettings property on the column to true so that the column knows to ignore it's own property setting in favor of the editor settings.
Then you use the InitializeRow event of the grid to assign the EditorControl of the cell in the row one or the other of the UltraMaskEdit controls.
