Which means what? You are still losing dropdownlist's items after postback?

Try to find out! If I was you, I'd set up some breakpoints - at least at page_load. You should see then WHAT is happening with your dropdown, and if you still don't understand WHY is it happening, no problem, post it here. Also you can try to comment out as much code as you can (both in codebehind and aspx page) to simplify the problem.

Hi Dear

To store values you can use the Database Connectivity the value will stored into sql or access database and to send mail to user you can use theh following code: -

1. To use it you have to import System.Net & System.Net.Mail namespaces.

2. You need to copy the following into web.config file before closing of configuration tag.

<system.net>
<mailSettings>
<smtp deliveryMethod="Network" from="<from mail id>">
<network

host="mail.dbmindia.com<host server name>"
userName="<from mail id>"
password="<password>"

port="25"
defaultCredentials="true"
/>

</smtp>

</mailSettings>

</system.net>

3. Use this code in your web page to send the mail to any id.

MailMessage mail1 = new MailMessage();

mail1.From = new MailAddress("<from email id>");
try
{
mail1.To.Add(<to mail id>);
}
catch (Exception mailex)
{
Response.Write("Email id is not in valid form");
Response.Write(mailex.ToString());
}

mail1.Subject = "<Subject for the mail";
mail1.IsBodyHtml = true;
mail1.Body = "<body message>"
SmtpClient smtp = new SmtpClient();
smtp.Credentials = new System.Net.NetworkCredential("<from mail id>", "<from mail id's password>");
try
{
smtp.Send(mail1);
}
catch (Exception ex)
{
Response.Write("Failed to send the mail");
Response.Write(ex.ToString());

}

you can test whether the value is Null before setting the SelectedValue. you can test against System.DBNull.Value

I am not a big fan of datasource controls but thats another discussion.You can bind the SelectedValue to a function that takes the value as parameter and test for NULL in it, or you can wire up the ondatabound event...

Calling a webservice using WCF? [modified]

moazzamahmed29-Jun-07 16:05

29-Jun-07 16:05

hi all

so I thought WCF could call web services too. Is this true?
or is it either WCF OR Web services?

if you CAN call a web service through WCF, how would you
configure its <endpoint>?

I have this all configured and my WS is running, & my proxy
instantiates fine too (meaning it doesnt return null), but when I make
a call to a method in my WS. it says "Object reference set to null".

Or do I have to create a different proxy for the web service? is
that the difference between WCF & WS?

thanks in advance!

Setting file access restrictions...

dekart_roo29-Jun-07 9:28

29-Jun-07 9:28

For an asp.net application, I'm using an xml file to read in configuration settings. The problem is... some of the settings can hold sensitive data. I want to ensure that the application can read in the values, but that the server will not acknowledge any http requests on the file. Prior programming conventions would dictate placing the configuration file somewhere outside of the scope of the web root, but that makes for more difficult installations... I'm trying to keep the whole application limited to one directory.

So... is there a web.config setting I could use to grant server access to a file, but not http access?

You can use the location element in ASP.NET 2.0 (not sure about previous versions) MSDN[^]

Thanks a lot; knowing this is definitely a big piece of the puzzle, as it will surely be how I target the specific file. But I'm still unsure of the specific configuration that will instruct IIS to reject http requests for that file, while still allowing server requests.

Row index for a link button in a grid

29-Jun-07 5:08

How can I find the row index when a linkbutton is clicked within a grid?

<asp:TemplateField HeaderText="BName" SortExpression="strBName">
<EditItemTemplate> </EditItemTemplate>
<ControlStyle CssClass="grid" />
<ItemStyle CssClass="grid_row_left" HorizontalAlign="Left" Font-Bold="False" />
<HeaderStyle HorizontalAlign="Left" />
<ItemTemplate>
<asp:LinkButton ID="LinkButton1" runat="server" OnClick="LinkButton1_Click" Text='<%# Eval("strBName") %>'></asp:LinkButton><br />
</ItemTemplate>
</asp:TemplateField>

Private Sub GridView1_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles GridView1.RowCommand

e.CommandArgument does not give me the row index.

Thanks,
Martin

Microsoft help suggest setting it in the row create:

Sub CustomersGridView_RowCreated(ByVal sender As Object, ByVal e As GridViewRowEventArgs)
    
    ' The GridViewCommandEventArgs class does not contain a 
    ' property that indicates which row's command button was
    ' clicked. To identify which row's button was clicked, use 
    ' the button's CommandArgument property by setting it to the 
    ' row's index.
    If e.Row.RowType = DataControlRowType.DataRow Then
    
      ' Retrieve the LinkButton control from the first column.
      Dim addButton As LinkButton = CType(e.Row.Cells(0).Controls(0), LinkButton)
          
      ' Set the LinkButton's CommandArgument property with the
      ' row's index.
      addButton.CommandArgument = e.Row.RowIndex.ToString()
      
    End If

  End Sub

Hope that helps

unable to set connectionstring property of Sqldatasource used with gridView dynamically in asp.net 2.0 using c#
after using it
getting Exception :The connection name 'ConnectionString' was not found in the applications configuration or the connection string is empty.
in syntax <%$ConnectionStrings:ConnectionString%>
I'm thinking string after : is the key used in web.config file is it correct?
Please guide what is gone wrong?

following is the code snippet:

<asp:sqldatasource id="SqlDataSourceCat" runat="server" connectionstring="<%$ConnectionStrings:ConnectionString%>" updatecommand="UPDATE DXCategory SET CategoryName =@CategoryName Where CategoryId=@CategoryId" selectcommand="SELECT [CategoryID], [CategoryName] FROM [DXCategory] order by CategoryId desc">
<updateparameters>

Does your web.config have a ConnectionString with the name 'ConnectionString'? Because the code you provided (though only visible in html source) assumes so.

thank you Szukuro for reply.
Yes, web.config have a ConnectionString with the name 'ConnectionString' set as key name .
now i tried with another syntax as follows in aspx page
ConnectionString="ConnectionStrings:ConnectionString"
This is not giving exception but dat is not getting bound to the repeater.
Please guide.
Thank you.
