table.KeepTogether ? (table with paragraph).KeepTogether?

#1

hi Guys i got questions,

- i’m looking for a way to keep (small enough) tables on a single page.
- usually the tables have a paragraph above them (title), and i want to be sure that they are both on the same page.

ideally i’m looking for a kind of generic node so that i can append(as in group) other nodes and apply the KeepTogether property that ive only seen in paragraphs.

i was thinking about using the Section node but it doesn’t have that property.
anyone have any suggestions on how i can go about this?

greetings,

Simon

Hi
Thanks for your request. I think that you should use KeepWithNext property in this case. For example see the following code:

// Open document
Document doc = new Document(@"Test158\in.doc");
// Get collection of tables
NodeCollection tables = doc.GetChildNodes(NodeType.Table, true);
// Loop though all tables
foreach (Table tab in tables)
{
    Node previouseNode = tab.PreviousSibling;
    if (previouseNode != null)
    {
        if (previouseNode.NodeType == NodeType.Paragraph)
        {
            (previouseNode as Paragraph).ParagraphFormat.KeepWithNext = true;
        }
    }
}
// Save output
doc.Save(@"Test158\out.doc");

Hope this helps.
Best regards.

hey alexey,

thanks for the response

I tried to test your example by using 3 paragraphs to almost fill a page followed by one table with a couple of rows appended to it.

i tried setting the KeepWithNext property of the of the last paragraph (before the table) to true and also tried just leaving it false. Unfortunately the table was spanned across both pages in each case. The KeepWithNext property of paragraphs might not work on table nodes.

EDIT: i’ll give some code as an example in a few minutes

Hi
Thanks for additional information. Maybe you should set KeepWithNext to true for each paragraph in the table. For example see the following code:

// new document
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
// create a Paragraph to almost fill up the page
builder.Font.Name = "Times New Roman";
builder.Font.Size = 460;
builder.Writeln("A");
// Clear formating
builder.Font.ClearFormatting();
builder.CurrentParagraph.ParagraphBreakFont.ClearFormatting();
builder.ParagraphFormat.KeepWithNext = true;
// Insert title
builder.Writeln("This is a test title\v");
// Create table
builder.RowFormat.Height = 20;
builder.CellFormat.Width = 100;
for (int i = 0; i < 10; i++)
{
    builder.InsertCell();
    builder.Write("Please don't span me");
    builder.EndRow();
}
builder.EndTable();
// save it
doc.Save(@"Test158\out.doc");

Hope this helps.
Best regards.
