Escaping angle brackets

[EmanuelParticipant]

Hello,

trying to show text in a grid containing angle brackets results in hiding them as well as the text between them:

Lorum epsum hello <friendly> world.

results in

Lorum epsum hello world. because it seems that <friendly> is added as a tag to the DOM. Escaping it on the server side doesn’t help.

What’s the right way to escape it?

Thanks in advance,
Emanuel

Hi Emanuel,

As far as I know, the way to escape brackets is to encode them as: <code> instead of <code>

Hi, I have a similar situation, left brackets “<” in text. How do I escape a data field in a grid?

Thank you Peter, I looked at the link you provided but it doesn’t really answer the question. It says you need to encode the characters which I have done doing this…

Public Function GetSRQViewStreetPlatesGrid() As String
Dim cmd As New SqlCommand()
cmd.CommandType = CommandType.StoredProcedure
cmd.CommandText = “spSRQRequestsStreetPlatesOpen”
Dim data As DataSet = GetSRQViewStreetPlatesData(cmd)
Dim dr As DataRow
Dim dt As DataTable
dt = data.Tables(0)
For Each dr In dt.Rows
dr(“SignText”) = Uri.EscapeDataString(dr(“SignText”))
Next
Dim writer As New System.IO.StringWriter()
dt.WriteXml(writer, XmlWriteMode.WriteSchema, False)
Return writer.ToString()
End Function

But how do you decode the characters to display in a grid? I tried using the unescape function but does not work (data with < does not display).

{ text: ‘Text’, datafield: ‘SignText’, width: 200, editable: false, cellsrenderer: function(row, columnfield, value, defaulthtml, columnproperties, rowdata) {
return unescape(rowdata.SignText);
}
},

I got it to work…first remove the escape in the code behind…
Public Function GetSRQViewStreetPlatesGrid() As String
Dim cmd As New SqlCommand()
cmd.CommandType = CommandType.StoredProcedure
cmd.CommandText = “spSRQRequestsStreetPlatesOpen”
Dim data As DataSet = GetSRQViewStreetPlatesData(cmd)
Dim dt As DataTable
dt = data.Tables(0)
Dim writer As New System.IO.StringWriter()
dt.WriteXml(writer, XmlWriteMode.WriteSchema, False)
Return writer.ToString()
End Function

Then return cellsrenderer like this…
{ text: ‘Text’, datafield: ‘SignText’, width: 200, editable: false, cellsrenderer: function(row, columnfield, value, defaulthtml, columnproperties, rowdata) {
return rowdata.SignText.replace(“<“, less than code).replace(“>”, greater than code);
}
},

(because this is html I wrote out “less than code”)
