hi yzme,

Check the cardinality of Node "Visibility".If it is 0..1 or 0..n you have to initialized it.

For 0..n node use code inside wdDoInit.

wdContext.node<node_name>().addElement(wdContext.create<node_name>Element());

For 0..1 node use code inside wdDoInit.

wdContext.node<node_name>().bind(wdContext.create<node_name>Element());

Or you can make node (“Visibility”) cardinality either 1..1 or 1..n

Without creating any element you can’t set the value to the context node attribute like.

wdContext.currentVisibilityElement().setD29Visible(WDVisibility.VISIBLE);

wdContext.currentVisibilityElement().setD30Visible(WDVisibility.NONE);

wdContext.currentVisibilityElement().setD31Visible(WDVisibility.NONE);

If you initialize the node (Visibility) you will not get null pointer exception.

But if you create a table using the node “Visibility” it will not hide your table column. It will add a record in the table like.

-

---

VISIBLE NONE NONE

-

---

To hide the table column [by id] use the code inside wdDoModifyView

-

---

IWDTableColumn custidtableCol = (IWDTableColumn)view.getElement("col_custid");

custidtableCol.setVisible(WDVisibility.NONE);

Hi,

You can use Visibility Options for this.

Create a Value attribute of type Visibility which will be available in the Dictionary.

Bind IWDTableColumn.visible property to context attribute of (DDIC) type Visibility. Set attribute value to WDVisibility.NONE to hide column.

Once it is binded , you can change the Visibility behaviour by coding wherever u want :

wdcontext.currentContextElent().setVisibility("NONE");

i hit null pointer exception

what wrong with my code

Visibility

-d29Visible

-d30Visible

-d31Visible

wdContext.currentVisibilityElement().setD29Visible(WDVisibility.VISIBLE);

wdContext.currentVisibilityElement().setD30Visible(WDVisibility.NONE);

wdContext.currentVisibilityElement().setD31Visible(WDVisibility.NONE);

Hi,

IWDTableColumn CustIDCol = (IWDTableColumn)view.getElement("col_custid");

CustIDCol.setVisible(WDVisibility.NONE); // To hide column

CustIDCol.setVisible(WDVisibility.VISIBLE);//To view column

Node : Visibility

Attributes : d29Visible, d30Visible, d31Visible

wdContext.currentVisibilityElement().setd29Visible(WDVisibility.VISIBLE);

wdContext.currentVisibilityElement().setd30Visible(WDVisibility.NONE);

wdContext.currentVisibilityElement().setd31Visible(WDVisibility.NONE);

Attributes : d29Visible, d30Visible, d31Visible should be <b>com.sap.ide.webdynpro .uielementdefinition .Visibility</b> of type.

Hi Yzme,

can u just post the structure of your node... also tell me whether "Visibility" is the Child node or Parent Node.

Hi

Most probably cardinality of your node in which d29 resides is 0 to n. So you have to create element for that node.

Hi Yzme,

Bind IWDTableColumn.visible property to context attribute of (DDIC) type Visibility.

Set attribute value to WDVisibility.NONE to hide column.

Hi

You first create an attribute say saveView of type com.sap.ide.webdynpro.uielementdefinitions.Visibility

Now go to the property of the element col_custid you want to hide and bind the visible property to the above attribute saveView .

Now depending upon your condition you may hide your element

by the code in view

wdContext.currentContextElement().setSaveView(WDVisibility.NONE)
