How to put drop down in table control ?

Hi All,
I m writing one module pool program to edit table.
I want dropdown to one field so that user can select the appropriate value. And also I want to save that record.
So how to get the dropdown list and after editing that record how to save that in the database?
Thanx in advance.
-Umesh

Hi Umesh,
Please check this demo program RSDEMO_TABLE_CONTROL on how to add drop down list in table control. Also check this program DEMO_DYNPRO_TABCONT_LOOP_AT as well.
To save to database you can code something like this in PAI.
MODULE USER_COMMAND_0100 INPUT.
SAVE_OK = OK_CODE.
CLEAR OK_CODE.
CASE SAVE_OK.
 WHEN 'SAVE'.
 MODIFY <database table> FROM TABLE <table control>.
 IF SY-SUBRC = 0.
 ELSE.
 ENDIF.
 WHEN OTHERS.
ENDCASE.
ENDMODULE. " USER_COMMAND_0100 INPUT
Hope this will help.

Hi all,
I'm facing a problem in table maintainence generator main view screen...i've got two fields in my db table and i've created search help for both the fields for drop down option for both the fields in main view screen.....but the first field shows up drop down option were in the other does'nt....i've changed the layout of the screen and lenght of the text element as well, even altered or changed the length of the view screen but its not working out....what i'm i suppose to do to get show up the drop down option for the other field too so as to make the the end user find the list of entries in the field..............any suggestion or changes would be really appreciated and correct answers would be surely rewarded....
Answer need urgenlty..........

Check whether in the attributes of the field, whether you have put the "Dropdown" value for your field as "Listbox" or "Listbox with key".
Also check whether you have referenced the field directly to the data element.
HOpe this helps.

Drop down in table

hi,
I have a dropdown by key in a table with 50 values.when I select a value in this drop down the following method will be called.This method is used to set new values in a dropby index present in the same table.This is happening perfectly.When I press enter to go to the next row in the table,the dropdown by index is retaining previous values.when I select the value in it change in second row is reflected to the first row also.this should not happen.Old values in the previous row of the dynamic dropdown should be retained.Can u suggest what should be done.

Hi,
I did not study your code, but the behaviour you describe is clear.
You have to create the 50 nodes dynamically for each table row (to be precise: for each nodeElement the row is bound to), and bind the Dropdown element in the particular row to each of these nodes (with 50 elements).
This must be done dynimcally if you don't know how many rows your table will contain. Otherwise, you can create the context for all table data design time.
Good luck.

How to get different values in drop down in table rows

Hi
I have an application, which has a drop down in the table. Each row is to have different values in its drop down based on the "characteristic" parameter. For eg. first row has characteristic as color, and the corresponding drop down will contain the color names. Second row has charateristic as weight, and the drop down will carry corresponding weight values.
I am getting the data from the backend as a flat table i.e. charaterisitc - value pair.
I think i will have to use the Drop Down by Index control, but i dont know how exactly to go about it.
Can any one please help in this regard.
Thanks & regards,
Anupreet

Hi Maksim
I am sorry, but i am not able to get you.
This is the piece of code that i wrote for populating the drop down:
IPrivateMaintainDocAttribView.IDropElement dropEle = null;
for(int i = 0;i<size;i++)
 dropEle = wdContext.nodeDrop().createDropElement();
 dropEle.setDropval(wdContext.nodeCtxNode_DocAttribs().getCtxNode_DocAttribsElementAt(i).getCmpCtx_Value());
 wdContext.nodeDrop().addElement(dropEle);
Here, Dropis the sub node to which i am putting the data and thisis linked to the table.
CtxNode_DocAttribs is the model node from where i am picking the data and setting in the subnode.
Thanks & regards,
Anupreet

Drop Down in table control

Hi All,
I am facing Problems here ;-
I have developed a table control in WDA4 application i have 3 dropdowns which are dependent on each other i.e. when i select the entry in the first one then corresponding to that entry the data should be shown in next drop down and same goes for the third one .I am using dropdown by index here .
Thnks ,
Sahil

Hello Sahiil,
You need to bind the table to a context node and the three drop downs separately to three context nodes. when you click one one of the drop downs, populate the the other nodes.
I hope this works for you.
Please feel free to ask if you have any further doubts.

Linking a library to a list - filtering data per selected drop down / check box item

Good day,
I am rather new to SharePoint and have run into a dilemma. Is it possible to link a library to a list, then create a parent-child relationship between the the department (list) to document (library)?
Example - I have a library that contains 100+ documents, the library is filtered using groups/subgroups.
IT
-> IT TX (30 docs)
-> IT WI (10 docs)
Biz Ops
-> Biz Ops WI (8 docs)
-> Biz Ops CA (5 docs)
In the list I created I have departments as a required field, and a dropdown tool that shows the 5 departments that contain items that need to be grouped together. (Biz Ops, IT, HR, Sales, and Compliance)
I have linked the library of documents to the form (list), using "Lookup (information already on this site)". All the documents in the library appear in the selection box within the list. However is it possible to first select a department which
then filters documents only tied to said department? So at the beginning of the list you choose the department you wish to browse the documents, then it filters out all documents not related to that department?
My apologies if this is long winded and confusing. Your help is most appreciative.
Cheers.

Hi,
According to your post, my understanding is that you wanted to filter the corresponding documents from a Document Library when you selected a department in a List.
I recommend that you can follow the steps as below to implement it in your environment.
1. Create a new Web Part Page and add the Document Library and the List web part into it.
2. Click the List web part, click the current web part’s drop-down arrow, choose Connections, Send Row of Data To, and then choose the Document Library web part.
3. Click the Document Library web part, choose the “All Items” view from the Selected View, click the current web part’s drop-down arrow, choose Connections, Get Filter Values From,
and then choose the List web part.
4. Open the Configure Connection – Webpage Dialog, choose the “Department” column from the Provider Field Name drop-down list and choose the “Group” column from the Consumer Field
Name drop-down list.
5. Click Apply, OK button, save the Web Part Page and test it in your environment.

How to avoid it?

Related Drop-down boxes - unique validation

Someone sent me a acroform, which has different sections that contain drop-down controls. Each drop-down has the options 1,2,3,4,5. These are supposed to be used to rank preferences. Is there a way where once you select "1" you are not allowed to choose it again in the remaining 4 drop-down boxes? I cannot find this anywhere in teh Acrobat PDF bible, albeit an older version.
regards,
Nat

We can do this with power of JavaScript. I would use the substring function in loading the values to dropdown.
for example I will have code similar to the following on DropDown1 'exit' event
var FilterChar = this.rawValue;
var DD2AllValues = "A1,A2,A3,a1,a2,a3,B1,B2,B3,b1,b2,b3,C1,C2,C3,c1,c2,c3";
DD2AllValues = DD2AllValues.split(",");
DropDown2.clearItems()
var curItem
var curChar
for (i=0,i<DD2AllValues.length,i++) {
 curItem = DD2AllValues[0];
 curChar = DD2AllValues.substring(0,1)
 if (curChar == FilterChar) {
 DropDown2.addItem(curItem);
hope this helps though you have to change a lot to make it work for your situation.
Good luck,

ESS Bsns pkg Bnfts &Pymnt - Overview Drop down and table not populated

Hi All,
We have configured ESS business package. Payslips in form of PDF are available in Benefits and payment.
Overview dropdown and table are not getting populated.
I checked context node rem, vcdata and attribute overview_sel in VcRem2Selection comp.
They are not populated at any place as well. How does this work?
Please guide

Hi Gangadharayya,
There are 2 ways of populating the dropdown.
Either u can create a simple type and bind the attribute to the SimpleType, or use the class ISimpleTypeModifiable and IModifiableValueSet to populate the values at run-time.
Hope this helps u

Drop down in a Table

Hi All,
I have a scenario where I need a drop down in table.It is binded to a context and should be populated with values(yes/no) from the context. But based on the data selected from the other columns it should default to yes or no. and then let user choose . How is this achieved.
Thanks all for your help.

Hi,
In a table, while u create binding,
1.Select the context node
2.In "Cell Editor of Table Column" u can select dropdown by index.
By doing so u will get dropdown in the table.
If the contexdt binded to the dropdown is character type, u can update the intenal table with "yes/no" and bind internal table to context node.
If not add a new field and update the field with "yes/no" value.
Thanks

Show Drop Down List

We have a report that prints data from a Sales Ticket table. The report has one parameter which is a Shift Start Date/Time. The Shift Start Date/Time is a field in the Sales Ticket table that goes with each Sales Ticket and also a field in a Shift table. When operator closes a shift, the Sales Tickets are updated with the Shift Start Date/Time and a new entry is made into the Shift table.
Now we need to run a sales ticket report that uses the Sales Ticket table and selects by Shift Start Date/time. Is there a way in the parameter entry screen to show user a drop down of all valid Shift Start Date/Time entries from the Shift table, this is the only way user will know what valid shift parameters exist. Now they have to run a shift report, pick the shift from the report and manually key that in as a parameter.
Thank you.

We are on CR XI product version 11.5.8.826.
I was reading about using a Command Object (connect to your datasource and entering sql command). If this is correct how could I get the result to show in a drop down list and have user select a line and use this as a parameter for creating the report?
Could you pleaseoint me in a direction where I might pick up some tutorial on how to do this. Thank you.
