I want to create a contact page using .Net? I tryed some code but the mail is coming in mailroot/queue folder. Is there any setting???

I have no idea what you're trying to do. If you send the mail using code, it will go where you send it. And, if you use a mailto: tag, it will go to the address you specify, via the client's mail program.

I can't really answer that, because I'm not even sure what you mean by contact page ( that is, its just a page, it may well send mail using the mail server on the server end, but it still seems trivial to me ). It makes more sense for you to tell us what you tried, what you want it to do, etc.

I have no idea what you're asking. You want links in the grid view to navigate to different pages ? Render links in the rows to the pages you want. You want something different, then please try to explain it better.

I got the data in the gridview from database assume i have 5 rows.
in that each row should go to a separate url(should have link) or with same page different data i tried it i am getting the same page again n again
|

Do what I said - render URLs in your grid view based on the content of the data in each row. I assume the URL you want relates to the row data in some way ? The obvious way is that query string parameter is set according to the data in the row.

you can use GridViewRow and a select the data to can pass it to different page on link click. for any link you can use Gridview Template Field.

I'm developing an e-commerce web-based system & have problem in Shopping Cart part. i.e. update quantity & delete item from cart. This is code-behind for my Cart.aspx.
<pre>
'other code above
Protected Sub GridView1_RowDeleting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewDeleteEventArgs) Handles GridView1.RowDeleting
cart.DeleteItem(e.RowIndex) 'error here
GridView1.DataBind()
End Sub
Protected Sub GridView1_RowEditing(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewEditEventArgs) Handles GridView1.RowEditing
GridView1.EditIndex = e.NewEditIndex
GridView1.DataBind()
End Sub
Protected Sub GridView1_RowUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewUpdateEventArgs) Handles GridView1.RowUpdating
Dim cell As DataControlFieldCell
cell = GridView1.Rows(e.RowIndex).Controls(3)
Dim t As TextBox = cell.Controls(0)
Try
Dim q As Integer
q = Integer.Parse(t.Text)
cart.UpdateQuantity(e.RowIndex, q) 'error here
Catch ex As FormatException
e.Cancel = True
End Try
GridView1.EditIndex = -1
GridView1.DataBind()
End Sub
Protected Sub GridView1_RowCancelingEdit(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCancelEditEventArgs) Handles GridView1.RowCancelingEdit
e.Cancel = True
GridView1.EditIndex = -1
GridView1.DataBind()
End Sub
'other code below
</pre>
The error saying that:
Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

I *think* you're asking how to enforce login ? The way I do that, is to make all pages that are protected, derive from a base class which checks if the user is logged in, and, if not, redirect to the login page. I suspect if you're using built in stuff, there'd be a config setting for the login page and it would redirect, but I prefer to write code.

WEll, it usually helps if you tell us what line has the error. In this case, tho, I think it's clear.
Saba02 wrote: System.Web.UI.WebControls.Login l =((Login)Wizard1.FindControl("Login1"));
In the first case you specify the full namespace of the control, in the second, you do not. Obviously you have another class called Login somewhere, and that is in scope, so you need to full scope the login control on the right, so the two sides both point to the same object, instead of two different objects with the same name.
Consider also renaming your Login class so this doesn't happen again.

Hi,
Following on from my other question, I have a GridView which is bound to a SqlDataSource. It has several pages. In my PageLoad() event handler I can get a count of how many pages are on the gridview by the GridView.PageCount property. If that's the case, I'd like to iterate through each page and find a row from the GridView.DataKeys property with a column matching a particular value and select the row.
I've tried iterating through each page by setting the GridView.PageIndex property and then getting the GridView.DataKeys property but the latter isn't updated - it only gets the first (displayed) page's set of values.
|

Have you tried looping through the rows after binding.
<br />
GridView1.DataBind()<br />
<br />
For Each row In GridView1.Rows()<br />
'Do whatever<br />
Next <br />
<br />

Hi
I have a GridView on my ASP.NET 2.0 page which I've populated from a SqlDataSource. It all works great but now I want to use the same page and pass the ID (or primary key value) into the page via a parameter. I want the Gridview to then select the entry with the corresponding ID in the GridView.
In other words, if I open the page without passing a parameter, the gridview shows the data as usual (I've used a select column which highlights the selected row).
If I pass a parameter in, I want the correct page in the GridView to be displayed along with the correct row highlighted.
Is this possible?
Thanks

Yes, this is possible. I would recommend using a Details View instead of a Grid View, for the simple reason that the Details View is designed to show 1 record whilst the Grid View is for many.
To do this, in the Grid View set the select function to something like Server.Transfer("DetailsViewPage.aspx?ID="+IDFieldFromGridView)
Then in in the Details View page, do:
<br />
If Request.QueryString("ID") = ""<br />
Server.Transfer("GridViewPage.aspx")<br />
End If<br />
<br />
'Pragmatically set params for Details View<br />
Don't you just hate coming up with something to put here?
