Formatting via Events

ASPxGridView has three events that enable you to provide custom display text for individual group rows, data and summary cells. These are:

  • ASPxGridView.CustomColumnDisplayText - enables you to provide custom display text for any cell.

    Expanded Example 1

    This example demonstrates how to display the "empty" string within the Units On Order column's cells if they contain zero values.

    The image below shows the result:

  • ASPxGridView.CustomGroupDisplayText - allows you to provide custom content for individual group rows.

    Expanded Example 2

    This example demonstrates how to implement custom grouping. The data is grouped by the 'Unit Price' column, and the column's rows that have values between 0 and 10 are combined into a single group. Rows whose values fall between 10 and 20 are combined into another group, etc.

    The 'Unit Price' column's GridDataColumnSettings.SortMode property is set to 'Custom', and the ASPxGridView.CustomColumnGroup and ASPxGridView.CustomColumnSort events are handled identically.

    Additionally, the ASPxGridView.CustomGroupDisplayText event is handled to replace the default text displayed within group rows.

    The image below shows the result.

    Note

    Refer to the How to implement custom grouping logic for ASPxGridView columns online example to review how it works.

  • ASPxGridView.SummaryDisplayText - enables custom display text to be provided for any total or group summary value.
