Find(String) Method

In This Topic

Searches the text of the RichTextBox control for a string.

Syntax

Visual Basic
C#

'Declaration
 
Public Overloads Function Find( _
   ByVal str As String _
) As Integer

public int Find( 
   string str
)

Parameters

str: The text to locate in the control.

Return Value

The location within the control where the search text was found or a negative one (-1) if the search string is not found or an empty search string is specified in the str parameter.

Remarks

The Find method searches for the text specified in the str parameter and returns the location of the first character within the control. If the property returns a negative value, the text string being searched for was not found within the contents of the control.

Note The Find methods that accept a string as a parameter cannot find text that is contained on more than one line of text within the RichTextBox. Performing such a search will return a value of negative one (-1).

Example

private void Detail_Format(object sender, System.EventArgs eArgs)
{
    if (this.RichTextBox1.Find("past due")!= -1)
    {
        this.txtPayNow.Visible=true;
    }
    else
    {
        this.txtPayNow.Visible=false;
    }
}

Visual Basic

Private Sub Detail_Format(ByVal sender As Object, ByVal e As System.EventArgs) Handles Detail.Format
    If Not Me.RichTextBox1.Find("past due") = -1 Then
        Me.txtPayNow.Visible = True
    Else
        Me.txtPayNow.Visible = False
    End If
End Sub
