How to find Values From Previous Page using Server.Transfer

bex · March 6th, 2009, 04:56 AM

Hi there
i have this code:

Code:

ProtectedSub CustomValidator1_ServerValidate(ByVal source AsObject, ByVal args As System.Web.UI.WebControls.ServerValidateEventArgs) Handles CustomValidator1.ServerValidate
args.IsValid = True
ForEach drv As DataRowView In SqlDataSource1.Select(DataSourceSelectArguments.Empty)
If drv("Name").ToString() = args.Value Then
args.IsValid = False
ExitFor
EndIf
Next
If args.IsValid Then
Me.Response.Redirect("send.aspx")
'Else
' Me.LblErrorMessage.Text = "Name Exsists"
EndIf
EndSub
ProtectedSub btnNext_Click1(ByVal sender AsObject, ByVal e As System.EventArgs) Handles btnNext.Click
'Response.Redirect("~/Send.aspx")
EndSub

every thing works in this page but when i navigate to send.aspx i cant find the controls from this page.
if i use postbackurl i see the controls but the validation does not occur.
i use this to fined the controls in send.aspx:

Code:

IfNot Page.PreviousPage IsNothingThen
Dim txtName As TextBox
Dim txtEmail As TextBox
Dim WorkName As TextBox
Dim Leadsorce As TextBox
Dim ListBox1 As ListBox
 
 
 
txtName = CType(PreviousPage.FindControl("txtName"), TextBox)
txtEmail = CType(PreviousPage.FindControl("txtEmail"), TextBox)
WorkName = CType(PreviousPage.FindControl("WorkName"), TextBox)
Leadsorce = CType(PreviousPage.FindControl("Leadsorce"), TextBox)
ListBox1 = CType(PreviousPage.FindControl("ListBox1"), ListBox)

i need to be able to click the next button the validation occurs and if the name does not exsist go to next .

at the moment everything works if i don't go to send.aspx.

thanks

Hello.

Long shot, but you are asking for page.previouspage in the if, but after you are just using previouspage. don't have a clue is that can cause a problem, but better check it out.

i took a diferent approach used 2 buttons next and search so when user =true btnNext=False.

I have another problem now.

it works from the SlqDatasource1 that is opening 1 table, i need to be able to change the connection to be dinamic, like:

Select Name FROM " & textbox1 " &.

i tryed to hardcode the connection in the page.aspx.vb but it gives me an error Connection is not declared

thanks

You better make a new thread for this, because the datasource define the Query in the page definition, but I don't know if you can change it.
