Setting check boxes in table from data

How would I check/uncheck a box in a table row depending on the mailmerge data?
I am currently using ExecuteWithRegions(SqlDataReader) to build the table, but the customer wants to see checkboxes rather than a simple mailmerge field.

Thanks for your inquiry. I think that you can use MergeField event handler for this. For example see the following code and attached documents.

public void Test263()
    // Create some datasource
    DataTable table = new DataTable("myTable");
    table.Columns.Add("IsAdmin", typeof(bool));
    // Add some data
    table.Rows.Add(new object[] { "1", "Alexey", true });
    table.Rows.Add(new object[] { "2", "Andrey", false });
    // Open template
    Document doc = new Document(@"Test263\in.doc");
    // Add MergeField event handler
    doc.MailMerge.MergeField += new MergeFieldEventHandler(MailMerge_MergeField263);
    // Execute mail merge
    // Save document
void MailMerge_MergeField263(object sender, MergeFieldEventArgs e)
    if (e.FieldName == "IsAdmin")
        // create document builder
        DocumentBuilder builder = new DocumentBuilder(e.Document);
        // Move to field
        builder.MoveToField(e.Field, true);
        // Insert checkbox (name will be unique for each formfield)
        builder.InsertCheckBox(e.Field.GetHashCode().ToString(), (bool)e.FieldValue, 10);
        e.Text = string.Empty;

Hope this helps.
Best regards.

OK, didn’t realise I had to insert them rather than simply checking existing ones in the template.
Works fine
