Kanban columns with remote data not working

[Martin Ares]

Hi,

I need to use Kanban control with remote data for cards as well as for columns.  However, I am not able to initiatize the data from the OnInitializedAsync method.  Only way is as per the sample on your website ie: to populate the column data upon variable initiatlization.  If I set the columndata in the  OnInitializedAsync, I simply get nothing showing.  Given this, I can't see how I could get the data (using a WASM).

Thanks for your help,

<SfKanban KeyField="Phase" TValue="InitiativeCheckListTemplate" >

    <SfDataManager Url="api/checklisttemplate" Adaptor="@Syncfusion.Blazor.Adaptors.WebApiAdaptor" CrossDomain="true"></SfDataManager>

    <KanbanColumns>

        @foreach (Syncfusion.Blazor.Kanban.ColumnModel item in columnData)

        {

            <KanbanColumn HeaderText="@item.HeaderText" KeyField="@item.KeyField"></KanbanColumn>

        }

    </KanbanColumns>

    <KanbanCardSettings HeaderField="Id" ContentField="Name"></KanbanCardSettings>

</SfKanban>

     // This one is working

@code {

    private List<Syncfusion.Blazor.Kanban.ColumnModel> columnData = new List<Syncfusion.Blazor.Kanban.ColumnModel>() {

    new Syncfusion.Blazor.Kanban.ColumnModel(){ HeaderText= "To Do", KeyField= new List<string>() { "0" } },

    new Syncfusion.Blazor.Kanban.ColumnModel() { HeaderText = "In Progress", KeyField = new List<string>() { "1" } },

    new Syncfusion.Blazor.Kanban.ColumnModel() { HeaderText = "Testing", KeyField = new List<string>() { "2" } },

    new Syncfusion.Blazor.Kanban.ColumnModel() { HeaderText = "Done", KeyField = new List<string>() { "3" } }};

}

//Not working

@code {

private List<Syncfusion.Blazor.Kanban.ColumnModel> columnData = new List<Syncfusion.Blazor.Kanban.ColumnModel>();

protected override async Task OnInitializedAsync()

    {

        columnData = new List<Syncfusion.Blazor.Kanban.ColumnModel>() {

        new Syncfusion.Blazor.Kanban.ColumnModel(){ HeaderText= "To Do", KeyField= new List<string>() { "0" } },

         new Syncfusion.Blazor.Kanban.ColumnModel() { HeaderText = "In Progress", KeyField = new List<string>() { "1" } },

        new Syncfusion.Blazor.Kanban.ColumnModel() { HeaderText = "Testing", KeyField = new List<string>() { "2" } },

        new Syncfusion.Blazor.Kanban.ColumnModel() { HeaderText = "Done", KeyField = new List<string>() { "3" } } };

    }

Hi Martin, 

 

Greetings from Syncfusion Support. 

 

We have validated your reported scenario at our end and let you know that the Kanban columns are rendered properly when we assigned the data for the column in the OnInitializedAsync method. We have prepared a client-side sample(WASM) for your reference that can be downloaded from the below link. 

 

<SfKanban TValue="TasksModel" KeyField="Status" DataSource="Tasks"> 

    <KanbanColumns> 

        @foreach (ColumnModel item in columnData) 

        { 

            <KanbanColumn HeaderText="@item.HeaderText" KeyField="@item.KeyField"></KanbanColumn> 

        } 

    </KanbanColumns> 

    <KanbanCardSettings HeaderField="Title" ContentField="Summary"></KanbanCardSettings> 

</SfKanban> 

 

private List<ColumnModel> columnData = new List<ColumnModel>(); 

 

protected override async Task OnInitializedAsync() 

{ 

    columnData = new List<ColumnModel>() { 

        new ColumnModel(){ HeaderText= "To Do", KeyField= new List<string>() { "Open" } }, 

        new ColumnModel(){ HeaderText= "In Progress", KeyField= new List<string>() { "InProgress"} }, 

        new ColumnModel(){ HeaderText= "Testing", KeyField= new List<string>() { "Testing" } }, 

        new ColumnModel(){ HeaderText= "Done", KeyField= new List<string>() { "Close" } } 

    }; 

}
