Hi,

I need to check if a formfield (text field) is multiline or not using itextsharp. Any code samples?

All I know is that I need to use PdfFormField.FF_MULTILINE but I don't know how to use that.

I am new to itextsharp so any working code samples will be more helpful.

Its not the textbox but the formfield. I have the following code:

C#

iTextSharp.text.pdf.PdfDictionary dic = new PdfDictionary();
dic = (iTextSharp.text.pdf.PdfDictionary)form.GetFieldItem(key).GetMerged(0);
//Check if textbox is multiline. If yes then do not truncate.
if (!(dic.GetAsNumber(iTextSharp.text.pdf.PdfName.FF) != null && dic.GetAsNumber(iTextSharp.text.pdf.PdfName.FF).IntValue == iTextSharp.text.pdf.PdfFormField.FF_MULTILINE))
{
 //some code
}

The above code is not working. Could someone point out the mistake?

I'm not sure what you want to achieve... ;(
Please, be more specific and provide more details.
Do you want to get text from formfield?

TextBox.TextMode Property
Gets or sets the behavior mode (single-line, multiline, or password) of the TextBox control.

C#:

C#

[ThemeableAttribute(false)]
public virtual TextBoxMode TextMode { get; set; }

ASP.NET

CSS

<asp:textbox textmode="TextBoxMode" xmlns:asp="#unknown" />

So :
TextBox txt = new TextBox();
... = txt.TextMode;

When the TextBox control is in multiline mode, you can control the number of rows displayed by setting the Rows property. You can also specify whether the text should wrap by setting the Wrap property.....

Alex.
