Set selectedKey of sap.m.Select (drop down) in sap.m.Table dynamically

[former_member597895]

Hi All,

I have such a problem - sap.m.Select (drop down) is a column of sap.m.Table and I am not able to set property selectedKey dynamically. The reason why I need this - because it might have different preselected values per table row. I will try to illustrate the problem with some coding:

aCells[n] = new sap.m.Select({ //aCells[n] is an array of table columns, part of table row template

Drop down:

selectedKey : "{rowDropdown}", //<---only hard code values work here

items : { path : "/",

template : oItemTemplate,

templateShareable: true }

}).setModel(oModel);

Table:

var oTable = new sap.m.Table({

fixedLayout : false,

columns : aHeader, //<---array of new sap.m.Column()

items: { path : "/",

template : oTemplate,

templateShareable: true } }).setModel(oModelRows);

Every other table column receives different values per row correctly, using the same approch: variables like "{rowCheckbox}", "{rowText}", "{rowDate}", and so on, but this does not work with drop down, I guess because drop down gets a separate model in step before for populating it's values, perhaps that 's why drop down then ignores the variable "{rowDropdown}".

Any ideas how to deal with such issue?

Thanks,

can it be "{/rowDropdown}"?

Hi Mindaugas Kazlauskas

What is the format of the data in the oModel you are binding to select control?

Hi All,

I am closing this thread, because I made it working this way:

1. creating one bing model for a table, which also contains data for each dropdown, means we have an array per row for each dropdown

2. bind the array mentioned in step 1 to a dropdown, for exmple this way:

var templVar = "rowDropdown"; //in my case it's a variable, in this example a constant

var templVarAll = "rowDropdownAll"; //in my case it's a variable, in this example a constant

var oItemTemplate = new sap.ui.core.Item({

key : "{key}",

text : "{text}" });

var oObject = new sap.m.Select({

selectedKey : "{"+templVar+"}",

items : {

path : templVarAll, //***no curly brackets round a variable here***

template : oItemTemplate,

templateShareable: true } });

3. set model mentioned in step 1 to a table

There is no need to give a name to a model, because just 1 model is used anyway.

If someone gets in similar problems and needs more details, let me know please.

Thanks,

you don't have to put dropdown data in the table data, you can just bind to a single list.

Hi All,

I am not sure on the following: must I set a separate small model to dropdown and then other model to table or can I copy a content of dropdown-model to model of a table and then set one big model to table? I guess this is a source of problems..

Thanks,

Hi Abdul,

is sap.m.select somehow different from this point of view?

I mean, why JSONModelName should be give inside variable template in this case, but works fine for others, like sap.m.input, etc.

[junwu]

no, model name always has to be there

[Abdul_Waheed]

Try below

{JSONModelName>rowDropdown}

Hi Dennis,

not really... with these templates "{rowCheckbox}", "{rowText}", "{rowDate}" I am populating table rows with some values in a loop, in fact all work fine without a slash symbol, just a drop down does not work.
