Patterns & Practices is not a single entity. You don't implement Patterns & Practices in a project, you implement a pattern such as Abstract Factory, Observer, or Strategy, or combinations of patterns.

Start here with these

Hi!
I have a question. How can i redirect to another page in a Button_click event. If i try with Response.Redirect("test.aspx") on test.aspx i get null values Request.Form("...") . If i try with Server.Transfer("...") i get an error:

"Sys.Webforms.PageRequestManagerParserErrorException:The message recieved from the server could not be parsed. Common causes for this error are when the response is modified by calls Response.Write(),response filters,HttpModules,or server trace is enabled. Details error parsing near ' y code:

<br />
protected void OkBTN_Click(object sender, ImageClickEventArgs e)<br />
    {<br />
        if (startDate <= endDate) Server.Transfer("test.aspx");<br />
        else<br />
        {<br />
            messageLbl.Text = dateError;<br />
            messageLbl.Visible = true;<br />
        }<br />
    }<br />

I just want to redirect to my test.aspx page and get some values with Request.Form().

Plese help me Smile | :)

Thank you!

Marta Paniti.

Server.Transfer("test.aspx", true);

true to preserve the QueryString and Form collections; false to clear the QueryString and Form collections.

I think you have to create and populate a gridview , a datatable or a simple HTML table on Button_click event.
You will find a lot of examples on the internet Wink | ;)

Hallo. I'm not sure exactly what you mean from the examples you suggested, since for Featured Agens some opened into a consistent format based on MagicBricks styles and others onto their own websites. If I'm getting you correctly, here's a really simple way I'd activate a datalist (which you've already styled to look the way you want)

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If IsPostBack = False Then
yourSubHere()
End If
End Sub

yourSubHere()
Using conn As New SqlConnection(as whatever)
Dim cmd As New SqlCommand("storedProcNameSelectingDatabaseContents", conn)
cmd.CommandType = Data.CommandType.StoredProcedure
conn.Open()
Using dr As SqlDataReader = cmd.ExecuteReader
datalistname.DataSource = dr
datalistname.DataBind()
datalistname.Visible = True
End Using
End Using
End Sub

Just a thought. Cool | :cool:

LDAP with ASP.net

Hi,
I am trying to authenticate a user by using his Windows credentials on an intranet website. In my web.config I have authentication set to Windows and in IIS I have enabled Integrated Windows authentication on my virtual directory.

I am using System.DirectoryServices also

I have the following code snippet written in C#

DirectoryEntry direntry = new DirectoryEntry("LDAP://DC=xyz,DC=COM",Text1.text,Text2.Text);<br />
Try<br />
{<br />
 Object nat;<br />
nat = direntry.NativeObject;<br />
Response.Redirect("~/Forms/someform.aspx");<br />
}<br />
catch(Exception e)<br />
{<br />
<br />
}<br />

The above mentioned code works only for a particular username and password and for all others the
code throws a System.DirectoryServices.DirectoryServicesCOMException. I do not have any impersonation enabled in my web.config.
Any more inputs from my side or is this info sufficient for anybody trying to throw some light on the problem. Thanx in advance.

You may be setting the the checked=true in the page load event . Place the code in the
if (! Page.isPostback)
{
checked=true ;
}

Try and come back

Hi all,
I am using this code to create textbox in asp.net pages and adding it to the panel control

Page load Event

TextBox txtbox;
           for (int i = 1; i < 10; i++)
           {
               txtbox = new TextBox();
               txtbox.ID = "mytextbox" + i;
               txtbox.AutoPostBack = false;
               Panel1.Controls.Add(txtbox);
           }

ViewSource

<div id="Panel1"><br />
	<br />
        <input name="mytextbox1" type="text" id="mytextbox1" /><input name="mytextbox2" type="text" id="mytextbox2" /><input name="mytextbox3" type="text" id="mytextbox3" /><input name="mytextbox4" type="text" id="mytextbox4" /><input name="mytextbox5" type="text" id="mytextbox5" /><input name="mytextbox6" type="text" id="mytextbox6" /><input name="mytextbox7" type="text" id="mytextbox7" /><input name="mytextbox8" type="text" id="mytextbox8" /><input name="mytextbox9" type="text" id="mytextbox9" /><br />
</div>

and want to retrive the textbox values in a button click event. But it not iterarting throgh the textbox collection

protected void Button2_Click(object sender, EventArgs e)
    {

        IterateThroughChildren(this);
    }

    void IterateThroughChildren(Control parent)
    {
        foreach (Control c in parent.Controls)
        {
            if (c.GetType().ToString().Equals("System.Web.UI.WebControls.TextBox")
                  && c.ID == null)
            {
                TextBox txtbox = (TextBox)c;
            }

            if (c.Controls.Count > 0)
            {
                IterateThroughChildren(c);
            }
        }
    }

Thanks in Advance

I think you have a bit of a logic error, c.ID will never be null. You also have an unnecessary recursion with the if(c.Controls.Count > 0)

All you need is

foreach(TextBox txt in Panel1.Controls)<br />
{<br />
<br />
}

I got the error as

Unable to cast object of type 'System.Web.UI.LiteralControl' to type 'System.Web.UI.WebControls.TextBox'.

Not Active18-Mar-08 3:16

18-Mar-08 3:16

TextBox txtbox = (TextBox)c;

You are trying to cast every control in the collection to a TextBox, including the LIteralControl, of course you will get this error. A Literal is not a TextBox Roll eyes | :rolleyes:

foreach(TextBox txt in Panel1.Controls)

This only gets you the TextBox controls in the collection
