Changing Color of single Table Cells

[Former Member]

Hi,

I have a question on how to handle the Color of single cells in a Table of a WebDynpro application.

In my project I created a View in which I want to show data of an underlying RFC Model via table.

The values of some columns contain negativ values, wich are marked and delivered by a '-' by the SAP System. These values I want to mark with the column property Semantic Color.

I tried to handle this by defining a value attribute 'negative' in the context of my view and pointed the Semantic Color property to this value.

For every line of the table I check on '-' and if found t the 'negative' Attribute is set to 'CRITICAL'.

Now when I start the Application the value is set for the whole column. Is there a posibility to change the Semantic Color property only for special cells of a table column or is there another posibility to solve this problem?

Best Regards,

Robert

Let "Rows" be the context node used as the the table's data source.

Add a subnode "State", cardinality 1:1, selection 1:1, singleton=false to "Rows".

Add a calculated attribute "TextColor" of type "TextViewSemanticColor" to "State".

In the generated get-method of the calculated attribute, return WDTextViewSemanticColor.NEGATIVE if the corresponding "Rows"-element has a negative value.

Bind the "semanticColor" property of the TextView (table cell editor of column showing values) to attribute "Rows.State.TextColor".

Thanks for this solution,

I`ve tried it and it works. One problem is, that I have many columns to check for negative values. So I took one Attribute for every column.That means many lines of code for the get-methods of 20 or more columns. It`s ok but maybe there is another way to handle this more efficiently.

The only way (I see at the moment) would be to build a reusable Web Dynpro component that provides this functionality by default (or could be configured to provide it).

But the effort to create such a component has to be taken into account.

The ALV component (already existing for WD ABAP, but not for NW04 WD Java) probably has this functionality?
