# DataUiGrid

## Introduction

The DataUiGrid is similar to Winforms PropertyGrid - a reflection-based UI object which can be used to display the properties on objects in real-time. Additionally, it can display properties using explicit get and set methods rather than reflection. It is used for the properties on Gum objects, but is written to be general purpose to be used in any applications.

It is included in the WpfDataUi.dll file which is part of Gum, so this library can be pulled out and used in any other application.

The DataUiGrid can be used with reflection or its Categories can be manually populated. Using reflection is easier to set up, but does not provide as much flexibility. Manually building up Categories takes more work, but provide the most flexibility.

## Adding References

The following references are needed for displaying the DataUiGrid:

* PresentationCore
* PresentationFramework
* System.Xaml
* WindowsBase

## Adding a DataUiGrid to XAML

To add a grid to your XAML you'll need to:

If using .NET 6+, add the following using:

```
xmlns:WpfDataUi="clr-namespace:WpfDataUi;assembly=WpfDataUiCore"
```

If using .NET 4.7, add the following using:

```xml
xmlns:WpfDataUi="clr-namespace:WpfDataUi;assembly=WpfDataUi"
```

Add the following inside a layout container (like a Grid):

```xml
<WpfDataUi:DataUiGrid Name="DataGrid"></WpfDataUi:DataUiGrid>
```

## Adding a DataUiGrid in Code

You can construct a grid in code just like any other WPF control.

```csharp
var grid = new DataUiGrid();
// add the grid to some layout object like a Grid or StackLayout...
```

## Using the grid in code

To use the grid in code you simply need to set its Instance member to an instance object you want to view. For example:

```csharp
// We'll use a MemoryStream to show that it works,
// but we could really use anything.
MemoryStream memoryStream = new MemoryStream();

this.DataGrid.Instance = memoryStream;
```

This produces a grid which looks like this:

![](/files/w4G9NhQJNQWOCz50eWGN)

Alternatively the Instance property can be data bound as shown in the following XAML:

```
<wpfdataui:DataUiGrid Instance="{Binding SelectedItem}"></wpfdataui:DataUiGrid>
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.flatredball.com/gum/code/gum-tool-code-contributing-and-plugins/datauigrid.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
