What do you mean by child page? is that a class derived from the original page?
If you're talking about 2 different ASPX pages, I think there is no way to retrieve values of a page from another page. I believe that as soon as you switch from one page to another, the previous page is discarded with everything in it, so I suppose there is no way to get back values from controls in it. You might be able to do so however if you're running a web user control and you want to retrieve the values of the parent page (containing the control). One thing for sure is that you can access programmatically any user control from the parent page and change the values of the controls in it, now whether you can go the other way around is something worth investigating.
Sorry, some theories, no solutions

Hi,
A tester has installed the web application that I created in ASP.NET 2.0 onto his test machine. (This is done using the .msi)
When the tester encounters an eror on the website, then he gets the default page for the error. This I think should not happen as I have set the following in the web.config
<customerrors mode="RemoteOnly" defaultredirect="CustomError.aspx">
I think he is supposed to be directed to the error page i.e. CustomError.aspx
Any thoughts please?
Thanks

In web.config you can set like this
<customErrors mode="RemoteOnly"/>

Hello there
I have written an image editor Application in ASP.net. I am doing some calculation at client side before posting using Java Script. I need to save my java script from any hacker as it Contains business logic. Is there any way to make javascript hidden...
Like I added the JavaScript File but when user saves the page from explorer then he can get the javascript file as well...
Support will be highly appreciated.
Regards
Rizwan Bashir

AFAIK, there's no way to prevent the user from downloading the script file, IMO what you might do is to make it hard to read/understand. Also, using javascript to contains business logic is a risk, and not a good practice. You should do it at the server side, and you can inscrease the responsiveness using AJAX to invoke the logic at the server side.

Hi to all,
Can anyone tell me how do I save the viewstate datatable where records of viewstate datatable are displayed on Datagrid on web form.
When I click on the save button all the data of datagrid or viewstate datatable should be saved in database.
Please help.
Thanks and Regards.
|
|
|
|
|
I'm curious as to why you need to persist the datatable in the ViewState. Do you want to keep the current state of the datagrid which supports paging? The simple way is to persist at the server side with the Session object, another option is to save it in DB, when the user click Save, you simply "commit" data in DB.

Am using this statement to authenticate users
"Call lo_IADs.OpenDSObject("WinNT://" & domain, user, pwd, 1)"
sometimes i get the error
"Multiple connections to a server or shared resource by the same user, using more than one user name, are not allowed. Disconnect all previous connections to the server or shared resource and try again"
only a server restart brings it back to normal
could anybody clarify what is happening, and is there a problem if users goes beyond 500.
thanks in advance

Hi all,
I am using paging in datagrid and implemented paging successfully.
In my application I have checkbox and Id field in datagrid,On button click I want to save Ids which having checkbox status checked.
I implement solution thats is working correctly if datagrid having single page.But if I checked checkboxes from different pages in datagrid only last page Ids get saved.
I mean In paging if i want to save entries of two pages i could not do that.
For Each gridItem In DataGrid1.Items
Dim chk As CheckBox = DirectCast(gridItem.FindControl("Status"), CheckBox)
If chk.Checked = True Then
lbl = DirectCast(gridItem.FindControl("ID"), Label)
'''''Saving code here
end if
next
|
|
|
|
|
You can save the checkbox ids in a viewstate and get it later while submitting.Otherwise use datagrid without paging.

Hi,
my checkbox is not binding to ant datafield.I am using viewstate to maintain Ids whose checkbox are checked but when loop
For Each gridItem In DataGrid1.Items
next
executes that consider datagrid items count=Item present on current page and not total datagrid item present on all pages.
I give some code for understanding
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not Page.IsPostBack Then
Fillgrid()
End If
Maintain_View()
Retrieve_Viewstate()
End Sub
Private Function Maintain_View()
Dim recordArray(DataGrid1.Items.Count - 1) As String
Dim n As Integer
Dim gridItem As DataGridItem
For Each gridItem In DataGrid1.Items
Dim chk As CheckBox = DirectCast(gridItem.FindControl("Status"), CheckBox)
Dim lbl As Label = DirectCast(gridItem.FindControl("ID"), Label)
If chk.Checked Then
recordArray(n) = lbl.Text
n += 1
End If
Next
ViewState("recordArray") = recordArray
End Function
Private Function Retrieve_Viewstate()
Dim recordArray(DataGrid1.Items.Count - 1) As String
Dim n As Integer
Dim gridItem As DataGridItem
For Each gridItem In DataGrid1.Items
Dim chk As CheckBox = DirectCast(gridItem.FindControl("Status"), CheckBox)
Dim lbl As Label = DirectCast(gridItem.FindControl("ID"), Label)
recordArray = ViewState("recordArray")
For n = 0 To DataGrid1.Items.Count - 1
If recordArray(n) = lbl.Text Then
chk.Checked = True
End If
Next
Next
End Function
I hope you help me...
