We need to see code, not screenshots.

How does your page store what tab is selected ? From what you've said, it doesn't sound like it does. If you add an asp:Hidden field in your page, you can store state info there, and viewstate will persist it between postbacks, just read it back in your javascript

Try writing more meaningful subjects, if you could, it really helps us to help you.

Hi Friends,
I have problem sending mail through ASP.Net.
whenever i try to send the mail from my server for which i have passed the details like smtp server and from address , i get an error that :

Mailbox unavailable. The server response was: <myemail@gmail.com> No such user here
But i have specified the from email address of my smtp server.
I have no clue that why is it searching for a gmail address on the smtp server.

I hope i am able to state my question/problem.

Thanks in advance.

I was debugging the code and after the send mail function it throws an exception.
This is where i got to know it is searching for the other address

I have a script that I can post to via a simple html form, but I can't figure out how to replicate the results with HttpWebRequest. Is there a way of getting the full functionality of a form submit via the HttpWebRequest?

Works:

Does not Work:
ASCIIEncoding encoder = new ASCIIEncoding();

string ifxLoc = "http://script-to-submit-to/login.dll?login";
string postData = "UserName=" + unme;
postData += "&PassWord=" + upswd;

byte[] data = encoder.GetBytes(postData);

HttpWebRequest s2oReq = (HttpWebRequest) WebRequest.Create(ifxLoc);
s2oReq.Method = "POST";
s2oReq.AllowAutoRedirect = true;
s2oReq.ContentType = "application/x-www-form-urlencoded";
s2oReq.ContentLength = data.Length;

Stream s2oStream = s2oReq.GetRequestStream();
s2oStream.Write(data, 0, data.Length);
s2oStream.Close();

Problem:
The HttpWebRequest seems to make a shallow connection to the login.dll, or doesn't fully follow through. I can't get it...working... in any way. It just returns the input of the html of the login page. Am I going about it in the wrong manner?

I also need a way to impliment the native redirect that's built into the simple form submit. If I use a response.redirect() after closing the stream, it is not the same.

Thanks!

Delete row from GridView which is bound to DataTable [modified]

Hi,
I have the Gridview which is bound to DataTable. In the GridView I have one button Delete for each row , when clicking on button the row need to be deleted from gridview.
private void BindGrid()
{
GridView1.DataSource = GetDataSource();
GridView1.DataBind();
}

protected System.Data.DataTable GetDataSource()
{
// const string key = "MyDataSource";
System.Data.DataTable aTable = new System.Data.DataTable();
aTable = (System.Data.DataTable)Session["dta"] ;

if (aTable == null)
{
aTable = CreateDataTableA(); -- In this CreateTable I am creating one DataTable and returning it.
Session["dta"] = aTable;

}
return aTable;

}

protected void GridView1_RowDeleting(object sender,GridViewDeleteEventArgs e)
{
int id = Convert.ToInt32( (GridView1.Rows[e.RowIndex].Cells[0].Text.ToString())); -- This statement containg null value always. This is giving exception because of this Null value.
FindRowByID(id).Delete();
BindGrid();
}

private DataRow FindRowByID(int id)
{
DataRow[] rows = GetDataSource().Select("District_ID = " + id.ToString());
return rows[0];
}
How to get the row’s cell value when delete button is clicked.

My Gridview syntax is like this:
<asp:gridview id="GridView1" runat="server" autogeneratecolumns="False" onrowdeleting="GridView1_RowDeleting">
<columns>
<asp:templatefield headertext="District_ID">
<edititemtemplate>
<asp:textbox id="TextBox1" runat="server">

<itemtemplate>
<asp:label id="Label1" runat="server" text="<%# DataBinder.Eval(Container.DataItem, "District_ID") %>" width="115px">

<asp:templatefield headertext="District_Name">
<edititemtemplate>
<asp:textbox id="TextBox2" runat="server">

<itemtemplate>
<asp:label id="Label2" runat="server" text="<%# DataBinder.Eval(Container.DataItem, "District_Name") %>">

<asp:commandfield buttontype="Button" deletetext="-" showdeletebutton="True" showheader="True">

Thanks in advance.

I suggest using an ObjectDataSource as an mediator between the GridView and the DataTable.

ObjectDataSource makes deleting, inserting, updating much easier.

Please read about using the ObjectDataSource an MSDN.
There are also quite a lot samples you can find using google (search terms: GridView ObjectDataSource)

Good luck

Values in array

I have a site where a user can input the first part of their post code to see if deliveries can be made to their area. Deliveries are only available in one area, so I use the following code:

	Private Sub btnSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSubmit.Click<br />
<br />
		Dim al As New ArrayList()<br />
		Dim i As Integer<br />
<br />
		For i = 1 To 32<br />
			al.Add("BS" & i)<br />
		Next i<br />
<br />
		Dim postCode = Me.txtPostCode.Text<br />
<br />
		Dim idx As Integer = al.BinarySearch(postCode, New CaseInsensitiveComparer())<br />
<br />
		If idx > 0 - 1 Then<br />
			Me.litMsg.Text = "We can collect from you"<br />
		Else<br />
			Me.litMsg.Text = "We do not collect from your area"<br />
		End If<br />
<br />
	End Sub

This finds the first postcode, but none of the others. Is there something wrong in the code? Should I just use a database table and pull values from there instead?

Couldn't you use the following if you're only supporting one delivery area:

<br />
<br />
string str = txtPostcode.text;<br />
if (str.StartsWith ("BS"))<br />
 ...<br />
else<br />
...<br />

Hi Richard, thanks for responding.

I could use the StartsWith method (which works), However, the postcodes range from BS1 to BS32. So if a user types 'BS43' they still get the 'We can collect from you' message.

Any thoughts?

Put all valid postcodes into an List<string> and use the Contains method:

List<string> postalcodes = new List<string>();

// add all codes
postalcodes.Add("BS1");
...

if (postalcodes.Contains(TextBox.Text))
...
else
...

You can store this in a file or in the database. Store a number, have code that increments the number called when a page is being served.

Property value after PostBack of UserControl

ZeedijkMike27-Jun-07 4:41

ZeedijkMike

27-Jun-07 4:41

Hi Allm

I have created a MaskedTextBox UserControl with a number of properties (Value, MinValue, MaxValue etc.) The UserControl works but I am not able to actually get the Value from the UserControl in the main apsx page. In short what I have done:

UserControl with a TextBox, a RangeValidator and some JavaScript to take care of the formatting.

In the main page:

<uc1:MaskedTextBox ID="MaskedTextBox2" runat="server" MinValue="-10000" MaxValue="10000" ErrorMessage="Value must be between {0} and {1}" Required="true" Display="None" /><br />
<br /><br />
<asp:Button ID="Button1" runat="server" Text="Button" /></div><br />
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label><br />

And in the code behind on_load event:

<br />
    protected void Page_Load(object sender, EventArgs e)<br />
    {<br />
        if (Page.IsPostBack)<br />
        {<br />
            Label2.Text = MaskedTextBox2.TextValue.ToString();<br />
        }<br />
    }<br />

But the value of the TextValue property is not available because the UserControl is loaded after the Page_Load event. How do I get the TextValue of the UserControl in the PostBack of the aspx page?
I would prefer not to use Session or ViewState because I would like to use the UserControl as I would use a 'normal' TextBox. Any ideas out there?

Kind regards,

Mike

If you want to do this I would suggest using an event

In your class

Public Event TextChanged(byval sender as object, byval e as eventargs)

Then pick up the text changed and bubble it

Public Sub textbox1_TextChanged(byval sender as object, byval e as eventargs) handles textbox1.textchanged
raiseevent textchanged(me, e)
end sub

Then you can use the event as normal within your aspx page.

If you need clarification please let me know

Thanks for the reply.

I'll try you solution. It looks somewhat better than the the solution I came up with my self. I try to dig in to the UserControl to get the value like this;

Label1.Text = (MaskedTextBox1.Controls[2] as TextBox).Text;

But working with events seems to be a more proper way.

Thanks,

Mike

Urs Enzler27-Jun-07 8:44

What is causing the postback? I assume the Button.

Put your code in the event handler of the postback initiator instead of the load event handler. That would then be the Button_Click event handler if my assumption is right.

Happy Programming

Can you post the code used for the TextValue property? Use ViewState for the TextValue property. I believe you must be using String variable instead.
