Property Value

Type	Description
String	A String value that specifies the filter item’s value.

Remarks

The FilterValue class provides two properties that enable you to specify the filter expression. These are: FilterValue.Value and FilterValue.Query properties.

The filter expression specified by the FilterValue.Query property takes priority over the filter expression specified by the FilterValue.Value property.

Use the FilterValue.Value property to create the Equals to expression.

C#

// Example: Equals to 50
FilterValue filterItem1 = new FilterValue();
filterItem1.DisplayText = "Filter Value1";
filterItem1.Value = "50";
e.Values.Add(filterItem1);

To create complex filter expressions, use the FilterValue.Query property:

C#

protected void ASPxGridView1_HeaderFilterFillItems(object sender,
 ASPxGridViewHeaderFilterEventArgs e)
{
    if (e.Column.FieldName != "ProductName") return;
    e.Values.Clear();
    FilterValue fv = new FilterValue("Low Price Products", null);
    fv.Query = string.Format("[UnitPrice] < {0} AND [Discontinued] = {1}", 10, true);
    e.Values.Add(fv);
}
