I was trying to learn how to make asp:Label detect web address inside texts and when a user clicks on the address it redirects to that address, but I got an error. The asp:Label displays its information from database inside a repeater control.
Here is the code:
public partial class New : System.Web.UI.Page
{
SqlCommand cmd = new SqlCommand();
SqlDataAdapter sda = new SqlDataAdapter();
DataSet ds = new DataSet();
DataTable dt = new DataTable();
private SqlConnection con = new SqlConnection("Data Source = (LocalDB)\\MSSQLLocalDB;AttachDbFilename=|DataDirectory|\\spotyearDB.mdf;Integrated Security = True");
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
BindRepeaterData();
}
lblData.Text = ConvertTextUrlToLink(lblData.Text);
}
public string ConvertTextUrlToLink(string rawString)
{
Regex linParser = new Regex(@"\b(?:http//|www\.)\S+\b", RegexOptions.Compiled | RegexOptions.IgnoreCase);
foreach (Match m in linParser.Matches(rawString))
{
if (m.Value.IndexOf("http") != -1 || m.Value.IndexOf("https") != -1)
{
rawString = rawString.Replace(m.Value, string.Format("<a target='_blank' href = '{0}'>{0}</a>", m.Value));
}
else
{
rawString = rawString.Replace(m.Value, string.Format("<a target='_blank' href = 'http://{0}'>{0}</a>", m.Value));
}
}
return rawString;
}
//Bind Data to Repeater Control
private void BindRepeaterData()
{
con.Open();
SqlCommand cmd = new SqlCommand("select * from [Table] Order By PostedDate desc", con);
DataSet ds = new DataSet();
SqlDataAdapter da = new SqlDataAdapter(cmd);
da.Fill(dt);
RepDetails.DataSource = dt;
RepDetails.DataBind();
con.Close();
}
}
From my C#, the error says:
"lblData.Text does not exist in the current context".
My label is inside a Table Cell, which is in Table Row and inside Repeater Control. And it displays text data from database like this:
<asp:label ID="lblData" runat="server" Text="<%#Eval ("comment")%>"></asp:label>
Could it be because the label is inside a Repeater Control?
HERE IS MY HTML
