TreeListCsvExportOptions.Separator Property

Specifies a character sequence that separates values in the exported CSV file.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v24.2.dll

NuGet Package: DevExpress.Blazor

#Declaration

C#
public string Separator { get; set; }

#Property Value

Type Description
String

Any character or character sequence.

#Remarks

CSV is a text format that stores data in rows where values are delimited by a separator. When you export TreeList content, the default separator is a comma (,). If the comma is used as a decimal separator in the current culture, the default separator is a semicolon (;).

Use the Separator property to change the default separator.

The following code snippet uses a space as a value separator:

Razor
<DxButton Text="Export to CSV" Click="ExportCsv_Click" />
<DxTreeList Data="TreeListData" KeyFieldName="Id" ParentKeyFieldName="ParentId" @ref="MyTreeList">
    <Columns>
        <DxTreeListDataColumn FieldName="Name" Caption="Task" />
        <DxTreeListDataColumn FieldName="EmployeeName" />
        <DxTreeListDataColumn FieldName="StartDate" />
        <DxTreeListDataColumn FieldName="DueDate" />
    </Columns>
</DxTreeList>

@code {
    ITreeList MyTreeList { get; set; }

    async Task ExportCsv_Click() {
        await MyTreeList.ExportToCsvAsync("ExportResult", new TreeListCsvExportOptions() {
            Separator = " "
        });
    }
}

You can use the QuoteStringsWithSeparators property to enclose values in quotation marks if they contain the same character or character sequence as a separator.
