Blank value in the drop down box

[Former Member]

Dear All,

I have created a dropdown box which gets the data from R/3.Data is coming correctly in the dropdownbox. Now i want to show blank line in the drop down box when it appears on the screen, as of now it appears with some data. Data should appear only when user click the dropdown button. Pls suggest.

Hi Anup,

I guess you are using DropdownbyIndex UI element. For this, Set your value node's cardinality to 0..N. So, it will display one blank line also.

If you are using Dropdownbykey then add one element with blank value.

You have many threads as open. Make habit to close other threads after resolving your problem. So, it will helpful for others also. Also, award points for helpful answers.

That's not correct. The blank entry stands for "nothing selected", so you must set the <b>selection </b>cardinality to 0:1 instead of 1:1 to get a "nothing selected" entry.

(assuming ByIndex data binding)

Set the lead selection to -1 by default.

Hi Anup,

When you set this cardinality then by default blank line appears in the dropdown if you have not alter its leadselection in your code.

wdContext.current<node>element().set<Property>("");

May be this would work.

Dear Noufal,

hi

the node that you have bound to the dropdown would have one of your data as the current element. add another element with say " " and set it as the current node element.
