Hi Saisharan,

In order to make only some rows readonly, you can define, a boolean type context attribute in the context node, with which you have bind the table. i.e bind the Datasource property of the table.

Now, bind this context attribute, to the readonly property of all the celleditors that you want to make readonly.

While adding elements to the context node, i.e adding rows to the table, in your code, for each row, that you want to make readonly, set this context attribute as true. For others, set it to false.

In this way, it will make only that rows readonly, where it is true.

Hope it helps.

hi,

As far as i understand, you can make the entire table readonly.

i was checking the same on my NWDS.

it does not seem that you can make rows or colums readonly selectively...

Hi,

You have already created a table.

And you want to make cell editor as read only for few columns.

In the data source node of the table create boolean attribute for columns which you want to make read only.

Let say you have only one column you want to make it read only for some reason.

(1) Create a boolean attribute "readonlyColumn" in the data source node of the table.

(2) Bind this attribute with the readonly property of the cell editor in the column.

Now your logic comes.

you will iterate through all the elements of the Table Node

Iterator attrIterator = wdContext.nodeTable().getNodeInfo().iterateAttributes();

for (int i = 0; i < wdContext.nodeTable().size(); i++) {

IWDNodeElement element = wdContext.nodeTable().getElementAt(i);

while (attrIterator.hasNext()) {

IWDAttributeInfo elem = (IWDAttributeInfo) attrIterator.next();

String attrName=elem.getName();

Object value=element.getAttributeValue(attrName);

if(condition for value is satisfied){

//Set column read only here

element.setAttributeValue("readonlyColumn",true);

}else{

element.setAttributeValue("readonlyColumn",false);

}

}

}

This code will solve your problem.

It will make the column readonly for the rows you want.

Feel free to ask queries.

Hi Saisharan,

Try to use Table cell variant for this requirement.

Hi,

Create a calculated attribute under the node which is bound to the table

Set its datatype as boolean

You will have a get/set Methods created for the calculatted attribute

In the get Method

public boolean getTableNodeReadOnly(IPrivateTView.ITableNodeElement element)

{

//@@begin getTableNodeReadOnly

if( < Your Condition> ) // Put the condition on which you need to disable the columns

return false;

return true;

//@@end

}

bind this attribute to the readOnly property of the UI Element for the column.

OR

1) Create an attribute of type boolean

2) set this attribute to false

Ex: wdContext.currentContextElement().setReadOnly(true); // ReadOnly is the name of the attribute.

3) bind this to the readOnly property of the UI element which is under the TableColumn.

Hi,

For rows you have to bind to readonly property of the table.
