string.replace mit DataBinder.Eval in ASP.NET
Um die Funktion replace im Databinder zu nutzen kann man folgende Vorgehensweise wählen:
Ohne Replace:
<a href=”page.aspx?id=<%#DataBinder.Eval(Container.DataItem, ” fileID “)%>“> LINKTEXT </a>
Mit Replace:
<a href=”page.aspx?id=<%#DataBinder.Eval(Container.DataItem, ” fileID “).replace(”textToFind”,”ReplaceWithThis”)%>“> LINKTEXT </a>
To use string.replace in databinder use the following example:
Without Replace:
<a href=”page.aspx?id=<%#DataBinder.Eval(Container.DataItem, “fileID”)%>“> LINKTEXT </a>
With Replace:
<a href=”page.aspx?id=<%#DataBinder.Eval(Container.DataItem, ” fileID “).replace(”textToFind”,”ReplaceWithThis”)%>“> LINKTEXT </a>
Was that helpfull? Please link my Blog.

Folgendes selbsterklärendes Beispiel:
Dim sqlStr As String = “SELECT * FROM Customers”
Dim dt As New DataTable
dt = …

GridView1.DataBind()
GridView1.Rows(1).Cells(1).Text = “my static Text”

VB.NET: Function Wordwrap in ASP.NET
Viele kennen vielleicht die PHP-Funktion „wordwrap“. Stand heute gibt es eine solche Funktion nicht im .NET Framework – Zumindest entzieht sich das meiner Kenntnis.
Gerade im Bereich HTML-Layout ist es problematisch Daten aus <TEXTAREA> Feldern vernünftig zu formatieren.
Grund genug eine Funktion wordwrap selbst zu bauen:
Public Function wordrap(ByVal currentText As String, ByVal_ maxCharsPerLine As Integer) As String
Dim returnString As String = “”
Dim rx As New Regex(“(\S{” & maxCharsPerLine.toString & “})”,_ RegexOptions.IgnoreCase)
returnString = rx.Replace(currentText, “$1 “)
Return returnString
End Function
War diese Information hilfreich? Dann würde ich mich über eine Verlinkung freuen.
Was this Information helpfull? I’d be very pleased if you link my page.

Warning Validation (XHTML 1.0 Transitional): Attribute ‘border’ is considered outdated. A newer construct is recommended.
In Visual Studio 2005 erscheint folgende Warnung:
“Warning Validation (XHTML 1.0 Transitional): Attribute ‘border’ is considered outdated. A newer construct is recommended.”
In meinem Beispiel hatte ich im Image-Tag folgendes Konstrukt:
<img height=”1″ alt=”" src=”images/black_dot.gif” mce_src=”images/black_dot.gif” width=”100%” border=”0″ />
Nach der neuen Microsoft Empfehlung macht man das jetzt so:
<img height=”1″ alt=”" src=”images/black_dot.gif” mce_src=”images/black_dot.gif” width=”100%” style=”border:none;” />
um einen Rahmen anzuzeigen so:
<img height=”1″ alt=”" src=”images/black_dot.gif” mce_src=”images/black_dot.gif” width=”100%” style=”border:7px;” />
Folge: Keine Warnmeldung mehr.

Warning 1 Validation (XHTML 1.0 Transitional): Attribute ‘bgcolor’ is considered outdated. A newer construct is recommended.
In Visual Studio erscheint folgende Warnung:
“Warning 1 Validation (XHTML 1.0 Transitional): Attribute ‘bgcolor’ is considered outdated. A newer construct is recommended.”
Im Body-Tag hatte ich folgendes Konstrukt:
<body bgcolor=”#FFFFFF”>
Dieses kann man mit diesem String ersetzen:
<body style=”background-color:#FFFFFF”>
Folge: Die Warnmeldung verschwindet.
