DropDownList and setLeadSelection

[david_fryda2]

Hi everyone,

I create da dropdownlistbykey and its value is bound to a simple type I created in the dictionary.

I am not able to set the leading selection to position 1 which is the frst value defined in the disctionary.

Here is the details of the node :

node DataSource

value attribute A

value attribute B

value attribute Currency which is bound the the simple type

I want to display the first value defined in the simple type in Currency.

Should I create another node under DataSource especialy for Currency ?

Thanks for the help.

Regards.

Hi Fryda

Use the LeadSelection Property

Hi Saravanan,

Do you mean this

wdContext.nodeNewCurrency().setLeadSelection(1);

?

It does not work.

Thanks.

Hi,

Have you check Cardinality?.

David,

Wat you get in the first position? And did you bind the currency value(attribute) to the Texts property of Dropdown by key?

David,

Create a seperate node with attribute of type simple and bind this with dropdown texts property

Wat ever be the first in enumeration will come first dropdown..

Set the node's cardinality 1..1

Hi,

After doing :

wdContext.nodeDataSource().setLeadSelection(1);

I get the following exception :

java.lang.IndexOutOfBoundsException: Index: 1, Size:1

Cardinality of the node is set to 1..n.

Thanks.

Hi

Try Cardinality of the node is set to 1..1

Kind Regards,

Hi,

I wrote the code in the modify method and it displays in the DDL the value 3.

The cardinality of the node is now set to 1..1.

I do not want that it displays the string 3. I want that it displays what is in position3 of the disctionary.

Thanks

David,

Wat is the structure of Enumeration type?

Saravan K,

What do you mean ?

I create da dictionary in Simple Type.

David,

Try Sridhar's approach. It should work. In your wdDoModifyView(), use this code:

if(firstTime){
IWDDropDownByKey d = (IWDDropDownByKey)view.getElement("DropDownByKey1");
d.setSelectedKey("1"); //Or the key part of the value you want to set.
}

Hi David,

I have a Simple Type like below.

Values Description

1 -- One

2 -- Two

3 -- Three.

if(firstTime){

IWDDropDownByKey ddkey = (IWDDropDownByKey)view.getElement("DropDownByKey");

ddkey.setSelectedKey("2");

}

Drop Down List Box is giving Default Select as 'Two'.

Is this not the solution you are looking for?

Regards,

Sridhar

Hi Sridhar,

It is the solution I am looking for.

The problem is that it display the string "2" instead of the value defined in the dictionary.

In addition, it works only if you defined a value attribute at the root of the Context. But what happened if you defined a Node and a value attribute in it.

Thanks

Hi David,

Do you have entry value - '2' in your simple type (Enumeration) ? If you don't have then it will simply displays '2', wont throw any error. If it has a value, then it shows the 2 - Description 'Two' in DD.

Thank you Sridhar for you help.

Hi,

Say your enumerated simple type is like this:

Value|Description

1 |Value1

2 |Value2

3 |Value3

Now if you say setSelectedKey("2"), the entry Value2 in your dropdown will be selected. Whatever you are entering as a parameter to setSelectedKey(), should be a key in the enumeration.

<i>But what happened if you defined a Node and a value attribute in it.</i>

What about this? I didn't understand. All you should be doing in this case is bind the selectedKey property to Node.nodeAttribute. Here is nodeAttribute is of type simpletype. Make sure the cardinality of the node is 1...1.

Hi Satyajit,

In fact I defined the cardinality of the node as 1..n.

It works good now.

Thanks.

Hi David,

We can Set lead selection in wdDoModifyView method.

IWDDropDownByKey ddkey = (IWDDropDownByKey)view.getElement("DropDownByKey");

ddkey.setSelectedKey("3");

DropDownByKey - Drop DownBy Key Control Name

3 - Data Dictionary Value.

It will lead to Perticular Element.

Hi,

I don't think you can set the lead selection for a enumerated simple type.

It'll be better if you create a value node explicitly for Currency.
