DataGrid Control

The DataGrid component is a graphical interface element used in applications to display and manipulate data. It allows users to view, edit, sort, filter, and manage data within a grid structure. Key functionalities include data binding, editing capabilities, sorting, filtering, and customizable columns. Applications include industrial monitoring systems, where real-time data needs visualization and interaction. Before usage, configure data sources, binding modes, and column properties. Usage involves setting up DataGrid in the display, defining columns, and enabling desired features like editing, sorting, and filtering through the configuration menu.

Requirements

This component is Portable. It runs both on Windows (WPF) and on Web Pages hosted in any platform.

Configuration

Double-click any DataGrid window object in the display to configure it.

General

DataGrid General Settings
Field	Description
Data Source	It defines the dataset table or query from which the data grid will get the data.
Control Name	It defines a name for the control so it can be accessed in the code-behind script. See Display Code Behind.
Selected Values	Captures the contents of the selected row using a string tag or array tag.
Selected Index	Captures the number of the currently selected row, starting with 0, using a tag.
Line Count	Receives the number of lines in the window using a selected tag.
Pause Update	Determines whether the DataGrid updates when the data changes by setting an object.
Grid Settings	Stores the DataGrid configuration using a retentive text tag, maintaining settings after a shutdown or restart.
Filter	Limits the displayed data using an SQL statement.
Binding	Sets the binding mode for the DataGrid. The options are: TwoWay updates the data source and UI interchangeably; OutputOnly allows data output without user input; InputOnly accepts user input without updating the data source.
Theme	Selects the visual style for the DataGrid.
Allow Edit	Enables editing of the selected values.
Allow Insert	Allows users to add rows.
Allow Delete	Allows row deletion.
Column Titles	Displays column titles.
Allow Sort	Allows users to sort data.
Transpose	Enables transposing of columns to rows.
Auto Columns	This option automatically includes all table or query columns in the window. Select this option to have the system include all columns without manual configuration.
OneClick Edit	Allows editing of cells on the first click.
Multiple Selection	Enables selecting multiple rows or cells simultaneously.
Header	Provides space for dragging column titles to group data.

Columns

DataGrid Configuration
Field	Description
Field	Specifies the name of the column in the DataGrid.
Title	Sets the text displayed as the header for the column.
Width	Defines the initial width of the column.
Sort	Determines the initial sort order for the column. The options are: None: The None option configures a column to disable sorting. Users cannot sort the data in this column, maintaining the original order of the data. Ascending: The Ascending option configures a column to sort data in ascending order. When applied, the data in this column will be arranged from the smallest to the largest value, or from A to Z for text entries. Descending: The Descending option configures a column to sort data in descending order. When applied, the data in this column will be arranged from the largest to the smallest value, or from Z to A for text entries.
Visible	Shows or hides the column in the DataGrid.
Editable	Allows or disallows editing of the column's data.
Show in Column Chooser	Includes the column in the column chooser, allowing users to select which columns to display.
Auto Resize	Automatically adjusts the column width based on content.
Editor	Sets the data type of the column (e.g., text, numeric). The options are: Text: The Text editor configures a column to allow users to input and edit plain text. It is ideal for columns that require alphanumeric data, such as names or descriptions. Numeric: The Numeric editor configures a column to accept only numerical input. This is useful for columns that store integer or decimal values, such as quantities or prices. CheckBox: The CheckBox editor configures a column to display a checkbox for each cell. Users can toggle the checkbox to represent binary data, such as active/inactive status or true/false values. MaskedText: The MaskedText editor configures a column to enforce a specific input format. It is used for fields like phone numbers or social security numbers, ensuring the data adheres to a required pattern. DateTime: The DateTime editor configures a column to allow users to select dates and times. This is useful for columns that record scheduling information, such as appointment dates or timestamps. Interval: The Interval editor configures a column to accept time spans. Users can input periods or durations, making it suitable for columns that track intervals, like project durations or time logs. ComboBox: The ComboBox editor configures a column to present a dropdown list of predefined options. This is useful for columns where users need to select from multiple values, such as categories or statuses. Color: The Color editor configures a column to allow users to select colors. This is particularly useful for columns that require color coding or selection, such as priority indicators or design elements.
Alignment	Specifies the horizontal alignment of the column content (e.g., left, right, center). The options are: Left: Align the data to the left side in the column. Right: Align the data to the right side in the column. Center: Align the data to the center in the column. Stretch: This will stretch the column horizontally.
Format	Defines the format for displaying the column's data (e.g., number format, date format).

Configuring a DataGrid Window

DataGrid with Columns Configured to Display Values with 2 Decimal Places

There are cases where even after setting the tag format to display in the grid and making data changes in the property window to show only 2 decimals, it does not work. In this way, the grid somehow shows more decimals than what is shown in the property window.

To resolve this situation, you can set the column where you want to limit the decimal values to numeric and in the format field put "0.00" in the DataGrid settings menu, this can make the data grid limit the number of decimal places.

How to make the selected row be the first row in the grid

TDataGridWindow grid = CurrentDisplay.GetDataGrid("Grid");

Xceed.Wpf.DataGrid.DataGridControl dg = grid.GridControl.DataGridObj;

ScrollViewer myScrollViewer = (ScrollViewer)dg.Template.FindName("PART_ScrollViewer", dg);
if (myScrollViewer == null || dg.Items.Count == 0)
    return;
        
string columnName = "Message";
    
int selIndex = -1;
for (int i = 0; i < dg.Items.Count; i++)
{                           
     DataRowView rowView = dg.Items[i] as DataRowView;     
     if (TK.To<string>(rowView.Row[columnName]).StartsWith(@tag.txtfind))
     {
          dg.Items.MoveCurrentTo(rowView);
          dg.SelectedItem = rowView;
          selIndex = i;
          break;
     }
}

if (selIndex >= 0)
    myScrollViewer.ScrollToVerticalOffset(selIndex);

Frozen Columns

The data grid also supports the feature to freeze columns. That means they stay visible while you scroll horizontally through all columns. This is a useful feature to keep a referencing column like an ID or a name always visible to keep your orientation while scrolling.

To freeze a numer of columns just set the FrozenColumnCount property to the number of columns you want to freeze.

In the code below for CodeBehind, it enables freezing/fixing the left-most columns in a DataGridWindow element.

The 'FixedColumnCount' property tallies the number of columns (from left to right) that will be fixed. The 'ShowFixedColumnSplitter' allows you to select the columns using the mouse (by clicking and dragging).

public void DisplayOpening()
{
	TDataGridWindow gridWindow = CurrentDisplay.GetDataGrid("grid");
	gridWindow.AfterInitilizationEvent += AfterInitilization;
}

public void DisplayIsOpen()
{
	// Add your code here
}

public void DisplayClosing()
{
	TDataGridWindow gridWindow = CurrentDisplay.GetDataGrid("grid");
	gridWindow.AfterInitilizationEvent -= AfterInitilization;
}

private void AfterInitilization(object sender, EventArgs e)
{
	TDataGridWindow gridWindow = CurrentDisplay.GetDataGrid("Grid");
	Xceed.Wpf.DataGrid.Views.TableView tableView = gridWindow.GridControl.DataGridObj.View as Xceed.Wpf.DataGrid.Views.TableView;
	tableView.FixedColumnCount = 1;
	tableView.ShowFixedColumnSplitter = true;
}
