Add data into a table

[Former Member]

Hi experts,

The problem is when I define the TABLE with 5 rows and 12 columns, I want to input data in each one of the cell of the table and I can´t do it because the fields appear disabled.

Can anyone help me please!!!

Several remarks:

A Table element contains exactly as much rows as its data source node has elements.

Even if the data source node contains no elements, there appear to be 5 rows initially, but these are only rendered for optical reasons.

If you want to have 5 editable rows, you need

- 5 node elements in the data source

- in each column you want to edit, you need a table cell editor that allows editing (e.g. InputField) and that is enabled and not readOnly.

Are all these preconditions satisfied in your case?

Hi Armin,

i´m trying to relate more than one node element to the data source and i can´t do that because the data source dont let me do this, could you explainme on detail how do that...

I apreciate your interest....Thanks

The data source node must have cardinality 0:N.

hi

Make sure that u have created a node and binded that node to the datasource of the table.

And the table cell editor is "inputfield".

In the wdDoInit() method of the implementation give the code

for(int i=0;i<5;i++)

{

IPrivate<view name>.I<node name>Element element=wdContext.node<node name>().create<node name>Element();

wdContext.node<node name>().addElement(element);

}

Also check if the cardinality of node is 1..n or 0..n.

What is the selection cardinality of the table's data source node?

Armin

hi

check the selection property of the node.Set it to 0..1 or 1..1. This might be the reason.
