Question

我有一个应用程序，其中我有一个连接到datagridview的数据库，我想用ComboBox过滤这个datagridview数据库。但我无法弄清楚如何做到这一点。我试着和我的文本框一样，但是没有用：

 <template name="DefaultIncrementalRefreshMessage" id="1">
    <string name="ApplVerID" id="1128">
        <constant value="9"/>
    </string>
    <string name="MessageType" id="35">
        <constant value="X"/>
    </string>
    <string name="SenderCompID" id="49">
        <constant value="MOEX"/>
    </string>
    <uInt32 name="MsgSeqNum" id="34"/>
    <uInt64 name="SendingTime" id="52"/>
    <uInt32 name="LastFragment" id="893" presence="optional"/>
    <sequence name="MDEntries">
        <length name="NoMDEntries" id="268"/>
        <uInt32 name="MDUpdateAction" id="279"/>
        <string name="MDEntryType" id="269"/>
        <uInt64 name="SecurityID" id="48" presence="optional"/>
        <uInt32 name="SecurityIDSource" id="22">
            <constant value="8"/>
        </uInt32>
        <string name="Symbol" id="55" presence="optional"/>
        <string name="SecurityGroup" id="1151" presence="optional"/>
        <uInt32 name="ExchangeTradingSessionID" id="5842" presence="optional"/>

        <int32 name="TrdType" id="828" presence="optional"/>
        <decimal name="LastPx" id="31" presence="optional"/>
        <int32 name="MDFlags" id="20017" presence="optional"/>
        <string name="Currency" id="15" presence="optional"/>
        <uInt64 name="Revision" id="20018" presence="optional"/>
        <string name="OrderSide" id="10504" presence="optional"/>
    </sequence>
</template>

尝试这样（你说combobox所以我使用了SelectionChangeCommited），

private void comboBox1_SelectionChangeCommitted(object sender, EventArgs e)
{
    (dataGridView1.DataSource as DataTable).DefaultView.RowFilter = string.Format("Propertyname= '{0}'", comboBox1.SelectedItem.ToString());
}
