QueryIsSearchColumnEventArgs Class

Namespace: DevExpress.XtraEditors

Assembly: DevExpress.XtraEditors.v20.2.dll

Declaration

public class QueryIsSearchColumnEventArgs

Public Class QueryIsSearchColumnEventArgs

Remarks

The SearchControl searches through all columns in the attached control (see RepositoryItemSearchControl.Client).

The QueryIsSearchColumn event allows you to specify whether or not to search in a specific column. The control raises this event for each column in the attached control. Read the Caption event argument to obtain the processed column's caption. You can also use the FieldName and DataType arguments to obtain the processed field's name and data type. If the SearchControl should not be permitted to search in the processed column, set the IsSearchColumn event argument to false.

The SearchControl.QueryIsSearchColumn and RepositoryItemSearchControl.QueryIsSearchColumn (see SearchControl.Properties) events are equivalent.

Examples

The code below shows how to search in the Ship Country column only.

using DevExpress.XtraEditors;

private void searchControl1_QueryIsSearchColumn(object sender, QueryIsSearchColumnEventArgs args) {
    if (args.FieldName != "ShipCountry")
        args.IsSearchColumn = false;    
}

Imports DevExpress.XtraEditors

Private Sub SearchControl1_QueryIsSearchColumn(sender As Object, args As QueryIsSearchColumnEventArgs) _
    Handles SearchControl1.QueryIsSearchColumn
    If args.FieldName <> "ShipCountry" Then
        args.IsSearchColumn = False
    End If
End Sub
