<分区>
使用 MVVM(无代码隐藏)，我想在选择时隐藏我的 DataGrid 列，我有以下代码:
<DataGrid ItemsSource="{Binding SSID}" Grid.Row="1" Margin="10,10,0,0" Height="200" Width="500" Grid.ColumnSpan="2" Name="dg" HorizontalAlignment="Left" AutoGenerateColumns="False">
<DataGrid.Columns>
<DataGridTextColumn Header="Network ID" Binding="{Binding _networkID}"></DataGridTextColumn>
<DataGridTextColumn Header="SSID" Binding="{Binding _ssid}"></DataGridTextColumn>
<DataGridTextColumn Header="VLAN" Binding="{Binding _vlan}"></DataGridTextColumn>
<DataGridTextColumn Visibility="{Binding _authenticationMode}" Binding="{Binding _authenticationMode}"></DataGridTextColumn>
<DataGridTextColumn Visibility="{Binding _authentication}" Binding="{Binding _authentication}"></DataGridTextColumn>
<DataGridTextColumn Visibility="{Binding _staticWEPKeyType}" Binding="{Binding _staticWEPKeyType}"></DataGridTextColumn>
<DataGridTextColumn Visibility="{Binding _staticWEPKeyLength}" Binding="{Binding _staticWEPKeyLength}"></DataGridTextColumn>
<DataGridTextColumn Visibility="{Binding _staticWEPKey1}" Binding="{Binding _staticWEPKey1}"></DataGridTextColumn>
<DataGridTextColumn Visibility="{Binding _staticWEPKey2}" Binding="{Binding _staticWEPKey2}"></DataGridTextColumn>
<DataGridTextColumn Visibility="{Binding _staticWEPKey3}" Binding="{Binding _staticWEPKey3}"></DataGridTextColumn>
<DataGridTextColumn Visibility="{Binding _staticWEPKey4}" Binding="{Binding _staticWEPKey4}"></DataGridTextColumn>
<DataGridTextColumn Visibility="{Binding _wpaPersonalKeyAC}" Binding="{Binding _wpaPersonalKeyAC}"></DataGridTextColumn>
</DataGrid.Columns>
</DataGrid>
C#代码是:
var ssid = new SSIDPropertyClass();
ssid._networkID = SSID.Count + 1;
ssid._ssid = EnteredSSIDAC;
ssid._vlan = VlanSSID;
if (ACSelectedSecurityType=="Static WEP")
{
ssid._authenticationMode = ACSelectedSecurityType;
ssid._authentication = ACStaticWEPSelectedAuthentication;
ssid._staticWEPKeyType = ACStaticWEPSelectedKeyType;
ssid._staticWEPKeyLength = ACStaticWEPSelectedKeyLength;
ssid._staticWEPKey1 = StaticWEPKey1;
ssid._staticWEPKey2 = StaticWEPKey2;
ssid._staticWEPKey3 = StaticWEPKey3;
ssid._staticWEPKey4 = StaticWEPKey4;
SSID.Add(ssid);
}
else if(ACSelectedSecurityType=="WPA/WPA2 Personal")
{
ssid._authenticationMode = ACSelectedSecurityType;
ssid._wpaPersonalKeyAC = WpaACKey;
SSID.Add(ssid);
}
我希望当执行 if block 时，它只在数据网格中添加该 block 列，而在其他 else if block 中添加相同的情况。实际上它总是显示我不需要的额外列例如，当 else if 被执行我只想显示我在 SSID 集合中添加的那两个，但它也显示是否 block 列。所以简而言之，我想将额外列的可见性设置为 false。任何人都可以解决我的问题我需要明天提交。任何帮助都将不胜感激？
