The DataGrid, in the context of the components, refers to the graphical element for visualization and handling structured data in your solutions displays. 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.

    g., text, numeric). The options are:

    Text: Sets a column to allow users to input and edit plain text. Ideal for columns that require alphanumeric data, such as names or descriptions.

    Numeric: Sets a column to accept only numerical input. Useful for columns that store integer or decimal values, such as quantities or prices.

    CheckBox: Sets 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: Sets a column to enforce a specific input format. Used for fields like phone numbers or social security numbers, ensuring the data adheres to a required pattern.

    Configuring a DataGrid Window

    DataGrid Columns with 2 Decimal Places

    There are cases where, even after setting the tag format to display in the grid and adjusting the property window to show only two decimals, it does not work. The grid may still display more decimals than specified in the property window.

    To resolve this issue, set the column to numeric and enter ‘0.00’ in the format field within the DataGrid settings menu. This will limit the number of decimal places displayed in the grid.

    Set Selected Row as First

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

    Code Block
    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 supports freezing columns, keeping them visible while you scroll horizontally. This feature is useful for keeping reference columns, like IDs or names, always visible for better orientation.

    To freeze a number of columns just set the FrozenColumnCount property to the desired number of columns.


    Image Added

    The code below demonstrates how to freeze the left-most columns in a DataGridWindow element using CodeBehind.

    • The FixedColumnCount property specifies the number of columns (from left to right) to be fixed.
    • The ShowFixedColumnSplitter property allows you to select columns using the mouse (by clicking and dragging)."
    Code Block
    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;
    }



    Runtime Execution

    Before using the DataGrid during runtime execution, configure data sources, binding modes, and column properties. To use the DataGrid, set it up in the display, define columns, and enable desired features like editing, sorting, and filtering through the configuration menu.

    In a production environment, the DataGrid can be used to monitor real-time data from various sensors. An operator can sort and filter this data to quickly identify and address any anomalies.
