    Convert Excel spreadsheet to PDF in .NET application Download VB.NET and C# samples

    For Excel to PDF .NET conversion task you can transform by one spreadsheet in Excel file only. You have to specify the spreadsheet name by assigning value of SourceTableSheetName property. Also you can setup XlsConvertMode property to define what a type of Excel to PDF conversion you would like to implement.
    The property takes two conversion mode value.
    Fast - MS Excel spreadsheets will be transformed much faster. However this way is good if you have homogeneous (similar) data for each MS Excel sheet column. If you have different data types stored in the same column please do not select this option.
    Detailed - MS Excel spreadsheets will be transformed slowly. However this way is good if you have heterogeneous (different) data types values (numbers, date or text) stored together in some MS Excel spreadsheets field. Conversion to PDF will not lose this motley data.
    allowExcelHeaders property is useful to define if the spreadsheet?s column titles will be specified as column headers within generated PDF output file or not.

    DataGridView Combo column (extended combobox) Download VB.NET and C# samples

    The DataGridViewComboColumn contains combobox for a DataGridView on your .NET form. The Combo column is not just a dropdown combobox, which appears when a DataGridView cell becomes the current cell. The .Net DataGridView Combo Column control has the following attractive features:

    This DataGridView Combo column is not just a dropdown combobox, which appears when a DataGridView cell becomes the current cell. This DataGridView Combo Column gives you ability to instantly update dropdown values with a really simple and friendly user interface. When you click the combo button a dropdown multiple columns grid of its list values will be shown below the combo. You can update values,and insert and delete rows into the dictionary DataGridView.

    You can set its DataSource, DisplayMember, and ValueMember to bind the Combo to a foreign table

    The control gives an ability to get a nesting combo box that filters values from a related child table. In a dictionary grid, you can view and edit related data in a child table. In your database a Master table has a one-to-many relationship with a Child table; so for each row of the Master table in Dictionary grid, you or your customer can view and edit the related


    rows of the Child table in a dictionary grid. For this case we have to define two string arrays with key fields' names MasterFields and ChildFields. To get the filtering we must identify Master and Child tables' key fields. These fields? names in both arrays must have the same order sequence.

    box.DisplayMode - Identifies what kind of data you would like to see in whole DataGridView customized column, as DataGridViewColumns.DisplayModes. You may choose the following values:
    ShowDisplayMember - default. DisplayMember will be shown in whole column
    ShowValueMember - ValueMember will be shown in whole column
    ShowValueMember_and_DisplayMember - ValueMember + DisplayMember will be shown together in a column

    box.allDictionaryColumns - The property identifies how many columns you need to see in the called Dictionary grid, as DataGridViewColumns.FieldsDisplayType(default is DisplayMember_ValueMember_only)
    You may set the following values:

    DataGridView Numeric Column Download VB.NET and C# samples

    This formatted intelligent NumericColumn control can mask the numbers, digits, decimal and checks the validation, and automatically set the delimiter location. You may input any number. If there is a numeric scale defined with the field, it is used to format the display and the input.

    Note By default the numeric column follows the formatting of the original column. If you define specific parameters (MaxLength, DecimalLength,...) for the column it will accept them. However if the original DataTable's column could not accept your defined parameters it will ignore your settings. For example, the datatype for an original numeric datatable's field is Integer and you give to the DecimalLength parameter some not zero value. For this case the control will not allow your users to insert decimal values. Please choose appropriate datatypes and column settings.

    The sample introduces how to add a DataGridColumnStyle that contains combobox to a DataGrid on your .Net form. It is not just a dropdown combobox, which appears when a datagrid cell becomes the current cell. This .Net DataGrid DataGridColumnStyle combobox control has the following attractive features:

    This combobox DataGridColumnStyle automatically fills the text at the cursor with the value of its dropdown values list. As characters are typed, the component finds the closest matching item from the list and automatically fills in the remaining characters. Appended characters are highlighted so that they are replaced by any further typing. For this auto-filling feature you can setup the character case sensibility.

    This DataGridColumnStyle gives you ability to instantly update dropdown values with a really simple and friendly user interface. When you click the additional dropdown button of the combo a dictionary of its list values will be displayed below the combo. You can update values, and insert and delete rows in the dictionary grid.

    The control gives an ability to get a nesting combo box that filters values from a related child table. In a dictionary grid, you can view and edit related data in a child table. In your database a Master table has a one-to-many relationship with a Child table; so for each row of the Master table in Dictionary grid, you or your customer can view and edit the related rows of the Child table in a dictionary grid.

    You can turn off all or some of these features and use the combobox DataGridColumnStyle just as an easy dropdown DataGrid combobox.

    You can set its DataSource, DisplayMember, and ValueMember to bind the combobox to a foreign table.

    How to Trap the Tab Key in a .NET Control?

    You are trying to create a control in .NET, and your control has to catch the Tab key. It might be a grid, where you would expect Tab to move between cells, or it might be an editor control. Now you would like to catch Tab and some other navigation keys that do not call OnKeyDown or OnKeyUp. How to intercept Tabs properly in .NET?
    You have to create a class that inherits from the System.Windows.Forms.Control and override the ProcessKeyMessage method. This method is called when a control receives a keyboard message. You suppose to trap the Tab on your Button. Just override the System.Windows.Forms.Button class and create your own myButton class:

    public class myButton : System.Windows.Forms.Button
    {
    public int PreProcessKey;

    public myButton()
    {
    }

    protected override bool ProcessKeyMessage(ref System.Windows.Forms.Message m)
    {
    PreProcessKey = m.WParam.ToInt32();
    return true;
    }
    }


    In your custom code you will be able to identify which key has been pressed before your button was activated:


    if (System.Windows.Forms.Keys.Tab.Equals(myButton.PreProcessKey)) MessageBox.Show("Tab is pressed!");

    How to draw a line in .NET? Line Control for .NET

    When a beginner who has VB6 experience first time opens .NET and just going about making a form up he/she could notice there is no Line in the .NET toolbox. What happened, where did it go?
    There is a difference from VB6 forms that Windows Forms .NET does not support the Line control.

    The Line class is based on System.Drawing namespace that provides access to GDI+ basic graphics functionality. A Line control is a graphical control that displays a horizontal, vertical, or diagonal one-pixel-wide line that can't be changed directly. The Line control can be changed dynamically at run time.
    The control class Line that is implemented in both languages (VB.Net and C#) is derived from System.Windows.Forms.Control. It overrides the OnPaint method to draw itself. The class will draw the line depending on its properties.

    Line controls can be displayed on forms, in picture boxes, and in another visual controls. You can move or resize your Line object by altering its X_Left, X_Right, Y_Left, and Y_Right properties. Also you can setup its Color property.

    Line ln = new Line();
    ln.X_Left = 20;
    ln.Y_Left = 150;
    ln.X_Right = 100;
    ln.Y_Right = 10;
    ln.Color = Color.Blue;

    How to implement a .NET application with the DataGrid Print class?

    The DataGrid Print class is intended to help you create a print output based on your .NET datagrid content. The class has been included into the DataGrid Columns .NET assembly since it is build for .NET WinForms datagrid control and very helpful for your .NET datagrid design. It helps you to implement a .NET Windows Forms application with a print preview and a print support.
    The following example creates a DataGridPrint object.

    private DataGridPrint PrintGrid;
    private void btnPrint_Click(object sender, System.EventArgs e)
    {
    frmPrint fpr = new frmPrint();
    fpr.Title = DataGrid1.CaptionText;
    fpr.ShowDialog();
    if (fpr.Result > 0)
    {
    PrintGrid = new DataGridPrint(printDocument1, DataGrid1, fpr.bBlackWhite);
    PrintGrid.PrintTitle = fpr.bTitle;
    PrintGrid.Title = fpr.Title;
    if (fpr.Result == 1) // Print
    {
    if (printDialog1.ShowDialog() == DialogResult.OK)
    {
    printDocument1.Print();
    }
    }
    else if (fpr.Result == 2) // Page setup
    {
    pageSetupDialog1.ShowDialog();
    }
    else if (fpr.Result == 3) // Preview
    {
    printPreviewDialog1.Icon = fpr.Icon;
    printPreviewDialog1.ShowDialog();
    }
    }
    }

    private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
    {
    e.HasMorePages = PrintGrid.Print(e.Graphics);
    }
