Hi I am using ASP.NET1.1 with Back end VB.NET Code.
I am trying to used Update command in Datagrid. But i am getting error in this line..
Private Sub DataGrid1_UpdateCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataGridCommandEventArgs) Handles DataGrid1.UpdateCommand
Dim eId As String
eId = DataGrid1.DataKeys(e.Item.ItemIndex) 'This line
End Sub
Error: "Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index"

I think the Datagrid is not returned by the function UpdateCommand. Hence it's throwing the error. Do check whether it returns any DataGrid1_UpdateCommand.

I have a webservice method that throws a soapexception if it has any errors, but when I test the service via the services.asmx?op=webserviceMethod page and an exception is thrown the web page shows a 500 error. I expected it to show some xml with the error message I created, but maybe I'm missing something.
Question: Is there a way to view the soap error message (xml) thats part of the SoapException instead of the 500 error?

If you modify the auto generated class that wraps the web service you can get the raw xml. I was more or less just curious about whether or not the detail I added to my soap exception was being sent to the consumer correctly. See OmegaMans article

Probably a simple question.
I have a form with a search button. The click event of the button calls a method for preforming a search. The search method returns a collection of business objects which I bind to a DataList.
The binding only appears to work properly when done in the OnInit event. That's fine.
The issue is in the order of the events. When the user clicks the search button the buttons click event isn't fired until after the init event.
<br />
protected void btnSearch_Click(object sender, EventArgs e)<br />
{<br />
List<Customers> customersList = Search();<br />
<br />
}<br />
I need to trigger a second post back to get the OnInit to fire again. Or do I?

Doing ASP.NET for several years, I never needed to handle OnInit(). Is there a reason you use it?
Usually my code looks something like this:
protected void Page_Load( object sender, EventArgs e )
{
if ( !IsPostBack )
{
List customersList = Search();
...
}
}
|
|
|
|

Reading the MSDN articles I was under the impression that dynamic content (in this case the template of my DataList has a custom control) needs to be created during the init event.
But, if you say you can do it through the Page_Load I believe ya. However, so far that has not worked.
This is what I have now tried:
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
if (SearchResults != null)
{
SearchResultsList.DataSource = SearchResults;
SearchResultsList.DataBind();
}
}
}
protected void btnSearch_Click(object sender, EventArgs e)
{
SearchResults = Search();
}
private List<Customer> SearchResults
{
get
{
return Session["SearchResults"] as List<Customer>;
}
set
{
Session["SearchResults"] = value;
}
}
When I hit search, nothing shows up. It doesn't appear as though the bind is ever happening.
It's probably something obvious. Usually is the case.

I guess you need to do something like this:
protected void btnSearch_Click(object sender, EventArgs e)
{
SearchResults = Search();
SearchResultsList.DataSource = SearchResults;
SearchResultsList.DataBind();
}
|
|
|
|

That got it!
I was actually already doing this when I first started, but nothing was showing up. Turns out the problem wasn't the order of where I set my DataSource but rather where I render my HTML in my custom control (the one in the template of the DataList).
Thanks for your help.

Hi
I am using ASP.Net 1.1.
I just want to get idea about AJAX with ASP.Net 1.1
Say for example, I have tmp.aspx which contain one textbox, a button and one lable. Now i want to print address from database on base of textbox value on click of button without server trip with AJAX. I have a function "GetAddress(String name)" in tmp.cs. So could anybody direct me how can i call this function using AJAX on click of button to save round trip.
Actully I have tried by assigning label using XMLHttpRequestobj.responsetext but whole response is coming. i just want to excute one function on button click thats it. Please direct me.
Actully this is not my actual requirnment but if i get this solution then i can handle any requirnment about AJAX.
Thanks in Advance to that genius who will make me clear about AJAX.
Thanks
Anand

I have a database in which I store the items that a customer added to the shoppingcart. Now I try to get the data and put it into the shoppingcart when the user loggs back in and there were items he didn't purchased yet but left in cart last time he was logged.
It will display the right quantity of each product, but it shows the Name and price of last recieved product in my ShoppingCart display on all products.
Here is code I have so far for getting items from DB and adding to ShoppingCart:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not Membership.GetUser() Is Nothing Then
StoreManager.ShoppingCart.UserID = Membership.GetUser().UserName
If Not Session("Logged") Then
StoreDB.GetShoppingCart(Membership.GetUser().UserName)
Session("Logged") = True
End If
Else
HttpContext.Current.Session("ShoppingCart") = New ShoppingCart()
StoreManager.ShoppingCart.UserID = ""
Session("Logged") = False
End If
End Sub
Public Shared Sub GetShoppingCart(ByVal userID As String)
Try
Using myCon As New SqlConnection(AppConnection.ConnectionString)
Dim myCom As SqlCommand = New SqlCommand("sprocGetShoppingCartItems", myCon)
myCom.CommandType = CommandType.StoredProcedure
myCom.Parameters.AddWithValue("@cartID", userID)
Dim prod As Product = New Product
Dim qty As Integer = 0
myCon.Open()
Using myRd As SqlDataReader = myCom.ExecuteReader(CommandBehavior.CloseConnection)
While myRd.Read()
prod.CategorieID = myRd.GetInt32(myRd.GetOrdinal("CategorieID"))
prod.ProductID = myRd.GetInt32(myRd.GetOrdinal("ProductID"))
prod.ProductName = myRd.GetString(myRd.GetOrdinal("ProductName"))
prod.ProductPrice = myRd.GetDecimal(myRd.GetOrdinal("ProductPrice"))
prod.ProductMini = myRd.GetString(myRd.GetOrdinal("ProductImage"))
prod.Qty = myRd.GetInt32(myRd.GetOrdinal("Quantity"))
MsgBox("Adding: " & prod.ProductName)
StoreManager.ShoppingCart.AddDB(prod, prod.Qty)
End While
myRd.Close()
End Using
End Using
Catch ex As Exception
' error handling set in Global.asax and web.config
Throw
End Try
End Sub
'Part of my ShoppingCart Class:
Public Class ShoppingCart
Private _items As List(Of OrderedProducts) = New List(Of OrderedProducts)
Public Sub New()
End Sub
Public Sub AddDB(ByVal product As Product, ByVal qty As Integer)
Dim orderedProd As OrderedProducts = New OrderedProducts(product, qty)
_items.Add(orderedProd)
End Sub
End Class
Public Shared ReadOnly Property ShoppingCart() As ShoppingCart
Get
If HttpContext.Current.Session("ShoppingCart") Is Nothing Then
HttpContext.Current.Session("ShoppingCart") = New ShoppingCart()
End If
Return CType(HttpContext.Current.Session("ShoppingCart"), ShoppingCart)
End Get
End Property

How can I truely get a date in the UK/GB format of dd/mm/yyy?
It's a dedicated server and everything is in GMT format as far as I can see, but nothing will change it to UK/GB format.
Any suggestions? I'd prefer to change a setting on the server than having an ASP .NET function, as it saves messing around.
Thanks,
Aaron

Your locale settings determine the default date format. Region and Language settings in the control panel is what you need.

Hi All,
I am working on GridView.
I used sorting on two columns ASC/DESC alternatively, as usually it is done.
Everything works fine but After changing the Sorting order GridView Displays the desired order but on GVMaterialMaster_SelectedIndexChanging Event,
Code:
protected void GVMaterialMaster_SelectedIndexChanging(object sender, GridViewSelectEventArgs e)
{
GridViewRow row = GVMaterialMaster.Rows[e.NewSelectedIndex];
string materialCode = row.Cells[0].Text;
}
the row.Cells[0].Text always have value of row.Cells[0] of GridView before Sorting. Means row.Cells[0] always have the same value whether sorting is changed or not.
Any help is appreciated,
Thanks

Have you checked whether SelectedIndexChanging Event is firing??
|
|
|
|

Thanks Venkatesh for Reply
Yes GVMaterialMaster_SelectedIndexChanging Event is firing on Selection.
Sorting on a cloumn change the order of rows of grids Rows but in SelectedIndexChanging Event of Gridview Value
of row.Cells[0].Text remains as it is before sorting.
Example: GridView's first Row's first cell has value 'A' and Last Row's first cell has value 'X'
Now after sorting GridView is showing first Row's first Cell's value 'X' and Last Row's first cell has value 'A'. Its fine.
Now I Select First Row so It Shold show value of row.Cells[0] as 'X' but It is showing value of row.Cells[0] as 'A'.
So Any Idea why It is not have row.Cells[0] in desird order ?
Thanks Again for kind help.
