Selecting a row in a grid

[Uwe Jädick]

 I am trying to select the data from a grid row based on AspNetUser to assign Roles to a selected user. 

Currently l am using userData : private List<UserModel> userData = null;

The application crashes with an exception after compiling. The second try the compiler finds errors: 

Severity Code Description Project File Line Suppression State 

Error (active) CS0029 Cannot implicitly convert type 'System.Collections.Generic.List' to 'System.Collections.Generic.List' 

 which is the beginning of the Task. 

 Changing "userData" To "UserModel results" in a compiler error: 

 Severity Code Description Project File Line Suppression State

 Error CS0029 Cannot implicitly convert type 'System.Collections.Generic.List' to 'System.Collections.Generic.List' 

 Please advice what would be the correct Parameter for TValue="" and private async Task SelectedRow(RowSelectEventArgs args) 

The rest of the code inside the Task is copied from the Syncfusion Demo

<SfGrid @ref="SfUserGrid" DataSource="userData" AllowFiltering="true" AllowGrouping="true" AllowPaging="true" AllowPdfExport="true" AllowExcelExport="true" AllowSorting="true" AllowSelection="true"

                                Toolbar="@toolbar">

                                    <HeaderTemplate>

                                        <span>@(GetDialogHeaderText(context as UserModel))</span>

                                        <SfButton OnClick="@Save" IsPrimary="true">@DialogButtonCaption</SfButton>

                                <GridEvents RowSelected="SelectedRow" TValue="UserModel"></GridEvents>

                                <GridColumns>

                                    <GridColumn HeaderText="User Name" Field="@nameof(UserModel.UserName)" Width="220px"></GridColumn>

                                    <GridColumn HeaderText="Email Address" Field="@nameof(UserModel.Email)" Width="220px"></GridColumn>

                                    <GridColumn HeaderText="Email Confirmed" Field="@nameof(UserModel.EmailConfirmed)" Width="100px"></GridColumn>

                                    <GridColumn HeaderText="Phone Confirmed" Field="@nameof(UserModel.PhoneNumberConfirmed)" Width="100px"></GridColumn>

                                    <GridColumn HeaderText="2 Factor Enabled" Field="@nameof(UserModel.TwoFactorEnabled)" Width="100px"></GridColumn>

                                    <GridColumn HeaderText="Access Failed" Field="@nameof(UserModel.AccessFailedCount)" Width="100px"></GridColumn>

                                </GridColumns>

                                <SfSpinner @bind-Visible="@VisibleProp"></SfSpinner>

                            </SfGrid>

@code {

    private SfGrid<UserModel>? SfUserGrid { get; set; }

private List<UserModel> userData = null;

    private string DialogButtonCaption { get; set; }

    private bool VisibleProp { get; set; } = false;

    [Parameter]

    public string Selection { get; set; }

:

:

    private async Task SelectedRow(RowSelectEventArgs<UserModel> args)

    {

        SelectedRowIndexes = await this.SfUserGrid.GetSelectedRowIndexes();

        TotalValue = SelectedRowIndexes.ToArray();

        Selection = "";

        foreach (var data in TotalValue)

        {

            Selection = Selection + " " + data.ToString();

        }

        StateHasChanged();

    }

Hello Naveen,

Thank you for getting beack to me on this topic. It seems that the demo I found is not working at all. Hence, I had to find a better solution.

I changed the RowSelected event and not using  SelectedRowIndexes = await this.SfUserGrid.GetSelectedRowIndexes(); anymore. Instead I am using var Selected = args.UserName to display the selected user. This is currently working.

The next issue I have is with Microsoft Identity Management and not Syncfusion anymore.

Best Regards

Uwe
