TableCell.SplitAsync(Int32, Int32, CancellationToken) Method

Splits the cell into multiple smaller cells.

Namespace: DevExpress.Blazor.RichEdit

Assembly: DevExpress.Blazor.RichEdit.v24.2.dll

NuGet Package: DevExpress.Blazor.RichEdit

Declaration

public ValueTask SplitAsync(
    int columnCount,
    int rowCount,
    CancellationToken cancellationToken = default(CancellationToken)
)

Parameters

Name	Type	Description
columnCount	Int32	The number of columns in the result cell range.
rowCount	Int32	The number of rows in the result cell range.

Optional Parameters

Name	Type	Default	Description
cancellationToken	CancellationToken	null	An object that propagates a cancellation notification.

Returns

Type	Description
ValueTask	A structure that stores an awaitable result of an asynchronous operation.

Remarks

Once you split a cell, its content moves to the first cell in the result cell range. All cells in the result range have the same appearance settings as the initial cell.

The following code snippet splits the first cell into 6 cells (3 columns and 2 rows):

<DxRichEdit @ref="richEdit" />

@code {
    DxRichEdit richEdit;
    protected override async Task OnAfterRenderAsync(bool firstRender) {
        if (firstRender)
            try {
                await InitializeDocument();
            }
            catch (TaskCanceledException) { }
        await base.OnAfterRenderAsync(firstRender);
    }

    async Task InitializeDocument() {
    /* Surround the code that contains an asynchronous operation with a try-catch block to handle
    the OperationCanceledException. This exception is thrown when an asynchronous operation is canceled. */
        try {
            var columnCount = 4;
            var rowCount = 5;
            richEdit.DocumentAPI.BeginUpdate();
            Table firstTable = await richEdit.DocumentAPI.Tables.CreateAsync(0, columnCount, rowCount);
            await firstTable.Rows[0].Cells[0].SplitAsync(3, 2);
            richEdit.DocumentAPI.EndUpdate();
        }
        catch (OperationCanceledException e) {
            Console.WriteLine($"{nameof(OperationCanceledException)} thrown with message: {e.Message}");
        }
    }
}
