I’m using Flex Grid in an Angular 6 project. One of the flex grid columns uses a drop down list as defined below with combo-box.
<wj-flex-grid-column [header]="'Current Season Name' [binding]="'Current_Season_Name'">
<ng-template wjFlexGridCellTemplate [cellType]="'Cell'" let-cell="cell" let-item="item">
<wj-combo-box class="wj-combo-box"
[(text)]="item.Current_Season_Name"
(textChanged)="getSelectedObject(item)"
[itemsSource]="Seasons"
[displayMemberPath]="'Season_Name'"
[selectedValuePath]="'Season_ID'"
[isEditable]="false"
[placeholder]="''">
</wj-combo-box>
</ng-template>
</wj-flex-grid-column>
Seasons is an array of objects that looks like this:
Season_End_Date : "2018-05-31 00:00:00"
Season_ID : 20000024
Season_Name : "Some Season"
Season_Start_Date : "2018-05-01 00:00:00"
When you pick from the dropdown/combo box list, the Season_Name value is displayed, which is correct, and that value is stored in the item.Current_Season_Name attribute, which is also correct.
What I want to do is get the current complete value list row and pass it to a function when the item is changed via the (textChanged)=“getSelectedObject(item)” binding.
‘item’ is the wrong parameter to pass here, as it passes the data row of the grid, what I want is the array row selected from the drop down list.
For example using [itemsSource]=“Seasons”:
(with abbreviated attribute names to save space here)
ID:"1234",Start:"July1",End:"July20",Name:"Season One"
[b]ID:"2345",Start:"July3",End:"July22",Name:"Season Two"[/b]
ID:"3456",Start:"July4",End:"July23",Name:"Season Three"
ID:"4567",Start:"July5",End:"July24",Name:"Season Four"
If we select the bolded second row, I want to pass the following to the function:
ID:“2345”,Start:“July3”,End:“July22”,Name:“Season Two”
Ideally as a single object so I can extract the values from it.
getSelectedObject(item) {
console.log(item.Season_End_Date)
console.log(item.Season_ID)
console.log(item.Season_Name)
console.log(item.Season_Start_Date)
}
What value can I pass in that (textChanged) binding to accomplish this?
