Event Data

The MailMergeExportFormShowing event's data class is MailMergeExportFormShowingEventArgs. The following properties provide information specific to this event:

Property Description
DialogResult Gets or sets the return value of a dialog box. Inherited from ShowFormEventArgs.
Handled Gets or sets whether an event was handled. If it was handled, the default actions are not required. Inherited from ShowFormEventArgs.

The Export Range dialog window provides a user interface to specify the SnapMailMergeExportOptions. It is invoked after selecting the publishing format of a mail-merge document in the Data Tools: Mail Merge toolbar.



This code snippet illustrates how to handle the SnapControl.MailMergeExportFormShowing event and specify the SnapMailMergeExportOptions.RecordSeparator and SnapMailMergeExportOptions.CustomSeparator properties to change the separator that is inserted between each pair of master sections.

// Provide a user interface to select a custom separator.
private void snapControl1_MailMergeExportFormShowing(object sender, MailMergeExportFormShowingEventArgs e) {

    SnapMailMergeExportOptions eOptions = e.Options;

    MailMergeExportFormControllerParameters controllerParameters =
        new MailMergeExportFormControllerParameters(this.snapControl1, eOptions);
    eOptions.RecordSeparator = RecordSeparator.Custom;
    e.Handled = true;

    using (MyMailMergeExportForm mergeForm =
        new MyMailMergeExportForm(controllerParameters)) {
        mergeForm.LookAndFeel.ParentLookAndFeel = this.snapControl1.LookAndFeel;
        e.DialogResult = mergeForm.ShowDialog(this);
        switch (mergeForm.SeparatorType) {
            case MyMailMergeExportForm.SeparatorTypeEnum.Html:
                eOptions.CustomSeparator.HtmlText = mergeForm.HtmlSeparator;
            case MyMailMergeExportForm.SeparatorTypeEnum.RichText:
                eOptions.CustomSeparator.Text = string.Empty;
