"Here's a comprehensive guide on how to connect dynamic data with angular-tree-grid components

ERROR TypeError: Cannot read property 'map' of undefined

Can anyone help with binding dynamic data? I'm currently using angular-tree-grid but struggling to bind dynamic data.

<html>    
    <db-angular-tree-grid 
        (expand)="onExpand($event)"
        [data]="data" 
        [configs]="configs">
    </db-angular-tree-grid> 
</html>

Answer №1

Looks like the variable data is not initialized at first, causing an issue with angular-tree-grid trying to use .map().

For a potential solution, consider the following code snippet:

<db-angular-tree-grid
    *ngIf="data"
    (expand)="onExpand($event)"
    [data]="data" 
    [configs]="configs">
</db-angular-tree-grid>

Alternatively, you could set a default value of an empty array like this:

<db-angular-tree-grid
    (expand)="onExpand($event)"
    [data]="data || []" 
    [configs]="configs">
</db-angular-tree-grid>
