Hey
For creating a Workflow application it would be really nice to get an event or virtual function on Render whicht asks which color a cell should have (for Current Cell Data)
Thx

Hi, You can do that in the current version by calling this function: http://doc.essentialobjects.com/library/1/jsdoc.public.gridcell.overridestyle.aspxHowever this is not an event. So you must call it explicitly. Thanks!

Hi
This doesn't work for me... I have to do it server side.
I need to style every Cell Background itself and for this I need Cell Value
People Day 1 Day2 Day3 Person1 red green yellow Person2 green yellow red
I just found out I can set Column.CellStyle.BackColor but this acts for the whole column.
Thx

Hi,
I don't know at all how I could use this in my app (The decision which colors isn't that easy...).
I think I need to render the Cell myself, isn't there an event or something like DatePicker DayRender?
I read a lot in this forum and found a lot of people which seem to have the same problem...
Thx

Hi, You don't do it the same way as DatePicker's DayRender. You usually prepare a DataTable first. For each data column you will have an additional column that will be used for styles. So for example, if your data has a single column like:
Code:
Column Name: Grade Row1: Good Row2: Bad Row3: Very Bad
If you want to display green for "Good", yellow for "Bad" and red for "Very Bad", then you will need to add an additional column into your DataTable:
Code:
Column Name: Grade Style Row1: Good good_grade_style Row2: Bad bad_grade_style Row3: Very Bad very_bad_grade_style
Here "good_grade_style", "bad_grade_style" and "very_bad_grade_style" are CSS classes that you must define in your CSS file. You would then set the columns' DataField to "Grade" and StyleField to "Style". At runtime, the Grid will apply each row's style to each cell. Note column "Style" does not exist in your physical database. It's just an additional column that you create in the memory. You can do it with database view, or an additional calculated column in your SELECT expression, or an additional column in DataTable object. Thanks

Hi
Ok I got It how I "could" do it, but the colors for Fore-Color and Back-Color are Saved on SQL-Server (User can Edit...), so i would have to generate a CSS class foreach Cell by runtime which sounds (...) for me...
Thx for your help but I think I have to build my own grid if there won't come a new feature (like DatePicker DayRender)...

Hi,
In that case you can always format each cell's Html directly. For example, instead of setting the cell value as "Good", you would format a string based on your data base value as "<div style='color:green'>Good</div>" and give the Grid that value.
Thanks

Hello Sir,
Just ask that if I put "<div style='color:green'>Good</div>" in the Grid Cell' value, when I enter the edit mode, what will be displayed in the cell editor? Is it only display "Good" to be edited or it will display "<div style='color:green'>Good</div>" for edit? Thank you.

Hi,
For TextBoxColumn, it will display exactly what you have put into the cell. If you want to change that behavior, you will need to use a CustomColumn to implement any additional logic yourself.
Thanks!
