突出显示行时是否触发任何事件？ [英] Is there any event triggered when highlighting a row?

问题描述

我创建了一个ListView来显示文档列表，然后创建了一个按钮 Button A来执行一些操作，我的要求是我希望按钮状态可以随着所选文档的更改而改变。

I created a ListView to show the list of documents, then created a button "Button A" to do some actions, my requirement is I would like the button status may be changed with the selected document changes.

Fox示例：下图中有三个文档，我希望在单击Order-00001或Order-00002时启用该按钮，并且对于Order禁用该按钮-00003，因为其中没有钱。

Fox example: there are three documents in the following graphic, I want the button is enabled when I click Order-00001 or Order-00002, and it is disabled for Order-00003 due to no money in it.

如果您能给我提示，当我单击一行时是否有任何事件要发生，我将不胜感激。非常感谢。

I appreciate if you could give me a hint if there is any event to be raised when I click a row. Thanks a lot.

推荐答案

为减少回调到服务器，没有选择行的事件。而是使用PXToolbarButton StateColumn属性来控制按钮的启用状态。

To reduce callback to the server there isn't a row selected event. Instead there is PXToolbarButton StateColumn property to control the button enabled state.

在声明按钮时，您将指定一个布尔DAC字段，该字段将基于该按钮启用/禁用按钮值。请注意，该按钮需要将DependOnGrid属性设置为网格的ID才能获取所选行：

When you declare your button, you specify a Boolean DAC field that will enable/disable the button based on it's value. Note that the button needs the DependOnGrid property set to the ID of the grid to get the selected row:

<px:PXToolBarButton Text="Button A" DependOnGrid="grid" StateColumn="IsButtonVisible">

IsButtonVisible是一个自定义的未绑定布尔DAC字段（您可以选择所需的任何名称，但isSelected / Selected除外）为复选框保留）：

IsButtonVisible is a custom unbound Boolean DAC field (you may choose any name you want except isSelected/Selected which is reserved for checkbox):

#region IsButtonVisible
public abstract class isButtonVisible : IBqlField
{
}

protected bool? _IsButtonVisible;
[PXBool]
[PXUIField(DisplayName = "Is Button Visible", Enabled = false, Visible = false)] 
public virtual bool? IsButtonVisible
{
    get
    {
        return _IsButtonVisible;
    }
    set
    {
        _IsButtonVisible = value;
    }
}
#endregion

您可以设置值根据您的业务逻辑在RowSelected事件中获取IsButtonVisible的信息：

You can set the value of IsButtonVisible in the RowSelected event based on your business logic:

protected virtual void DAC_RowSelected(PXCache sender, PXRowSelectedEventArgs e)
{
    DAC row = e.Row as DAC;

    if (row != null)
    {
        bool yourCondition = ???;
        row.IsButtonVisible = yourCondition;
    }
}
