Acumatica智能面板打开时不显示空数据消息问题

I get it—having to click refresh just to see the "no records" message isn't ideal for user experience. Let's fix that. Here's what's going on and how to resolve it:

The Problem #

Your Smart Panel's PXGrid loads fine when there's data, but when the TestSteps view has no records, the empty message only appears after manually clicking the grid's refresh button. This happens because the grid isn't properly triggering a data check when the panel first opens, even with AutoReload enabled.

Your Current Code #

First, let's recap your existing setup for context:

C# Graph Code #

public PXAction<GraphClass> GoToSteps;
[PXButton(Tooltip = "Open Popup" )]
[PXUIField(DisplayName = "Steps")]
public virtual void gotoSteps()
{
    TestSteps.AskExt(true);
    return;
}

Fixes to Implement #

1. Refresh the TestSteps View Before Opening the Panel #

The key issue is that when you call AskExt(true), the TestSteps view might not have been refreshed to confirm it's empty. Add a view refresh before opening the panel:

public PXAction<GraphClass> GoToSteps;
[PXButton(Tooltip = "Open Popup" )]
[PXUIField(DisplayName = "Steps")]
public virtual void gotoSteps()
{
    // Force the view to refresh so it knows it's empty (if no records exist)
    TestSteps.View.RequestRefresh();
    // Now open the panel
    TestSteps.AskExt(true);
    return;
}

2. Enhance the Smart Panel's AutoCallBack Configuration #

Your current AutoCallBack settings are partial—add explicit behavior to ensure the grid repaints properly when the panel loads:

Update the Smart Panel markup to include a full AutoCallBack block (replace the inline AutoCallBack-Target and AutoCallBack-Command attributes):

<px:PXSmartPanel ID="pnlTestSteps" runat="server" Height="400px" Width="1100px" 
    Caption="Test Steps" CaptionVisible="true" AutoReload="true" LoadOnDemand="true" 
    Key="TestSteps" Style="position: static" DesignView="Content">
    <AutoCallBack Target="StepsGrid" Command="Refresh">
        <Behavior CommitChanges="True" PostData="Page" RepaintControlsIDs="StepsGrid" />
    </AutoCallBack>
    <!-- Rest of your Smart Panel content remains the same -->
</px:PXSmartPanel>

3. Double-Check View Binding #

Make sure your TestSteps view in the graph is correctly defined as a select view pointing to the right DAC, and that the grid's DataMember="TestSteps" matches exactly.

Why These Fixes Work #

• TestSteps.View.RequestRefresh() ensures the view fetches the latest state (including empty) immediately before the panel opens, so the grid has accurate data to work with.
• The enhanced AutoCallBack tells the grid to explicitly refresh and repaint when the panel loads, which triggers the empty message rendering if there are no records.

These changes should make the empty message appear automatically as soon as the Smart Panel opens, no manual refresh required.
