Members

Remarks

The GridColumnFilterMode enumeration values specify whether grid data is filtered by value or display text.

Filter Data By Value (Default Behavior)

When the FilterMode property is set to Value, the grid filters rows by cell values.

<DxGrid Data="@Data" CustomizeCellDisplayText="Grid_CustomizeCellDisplayText" 
    ShowFilterRow="true" PageSize="7">
    <Columns>
        <DxGridDataColumn FieldName="Date" DisplayFormat="D" />
        <DxGridDataColumn FieldName="CloudCover" />
        <DxGridDataColumn FieldName="TemperatureC" TextAlignment="GridTextAlignment.Left" Caption="Forecast"
            FilterMode="GridColumnFilterMode.Value" />
    </Columns>
</DxGrid>

void Grid_CustomizeCellDisplayText(GridCustomizeCellDisplayTextEventArgs e) {
    if(e.FieldName == "TemperatureC") {
        int val = Convert.ToInt32(e.Value);
        if(val < 15)
            e.DisplayText = "Cold";
        else if(val < 25)
            e.DisplayText = "Warm";
        else 
            e.DisplayText = "Hot";
    }
}

Filter Data By Display Text

When the FilterMode property is set to DisplayText, the grid filters rows by display text. This scenario can be useful when you specify custom display text for cells (see the DisplayFormat property and CustomizeCellDisplayText event descriptions).

<DxGrid Data="@Data" CustomizeCellDisplayText="Grid_CustomizeCellDisplayText" 
    ShowFilterRow="true" PageSize="7">
    <Columns>
        <DxGridDataColumn FieldName="Date" DisplayFormat="D" 
            FilterMode="GridColumnFilterMode.DisplayText" />
        <DxGridDataColumn FieldName="CloudCover" />
        <DxGridDataColumn FieldName="TemperatureC" TextAlignment="GridTextAlignment.Left" Caption="Forecast"
            FilterMode="GridColumnFilterMode.DisplayText" />
    </Columns>
</DxGrid>

void Grid_CustomizeCellDisplayText(GridCustomizeCellDisplayTextEventArgs e) {
    if(e.FieldName == "TemperatureC") {
        int val = Convert.ToInt32(e.Value);
        if(val < 15)
            e.DisplayText = "Cold";
        else if(val < 25)
            e.DisplayText = "Warm";
        else 
            e.DisplayText = "Hot";
    }
}

Limitations

The Grid does not support filtering by display text when you use a Server Mode data source or GridDevExtremeDataSource.
