A document consists of different text parts: The main text, headers, footers and text frames. The TextPartCollection is a meta collection that allows the iteration of document elements in all document parts. The IFormattedText interface provides properties and methods common to all text parts in a TX Text Control document.
Additionally, an object of type IFormattedText has a separate Find method. In order to find and highlight a specific string in all text parts, the following easy code snippet can be used:
public void HighlightAll(string Text)
{
foreach (TXTextControl.IFormattedText obj in textControl1.TextParts)
{
int index = -1;
do
{
index = obj.Find(Text, index + 1,
TXTextControl.FindOptions.NoMessageBox);
obj.Selection.TextBackColor = Color.Red;
} while (index != -1);
}
}As a result, all instances of a specific string ("TEST") are highlighted in red:
