I have a public shared function and I'm trying to access the values of a text box and a session variable.
I'm getting the error "Cannot refer to an instance member of a class from within a shared method or shared member initializer without an explicit instance of the class."
Is there any way I can get to the values in the textboxes or session variables from within the method?

I want to call a non shared function in a shared function in which i am having a textbox control instance. Its giving no error but when i call this shared function from client callback it gives me no response
Any Idea except removing shared from the function.
Here is my code :
<WebMethod()> _
Public Shared Function myF() As String
Dim pg As New _Default
Return "{'Hello':'" & pg.setText & "'}"
End Function
Public Function setText() As String
Dim pg As New _Default
pg.TextBox1.Text = "This is a test"
Return pg.TextBox1.Text
End Function
I am using the Ajax AutoCompleteExtender control, and employing a public shared function to act as a web service without actually creating a web service. This approach works perfectly, however I would like to take this one step further and filter my query from a drop down list, however I am unable to accomplish this. Whenever I attempt to reference the drop down list from within the public funtion, I get:
"cannot refer to an instance member of a class from within a shared method or shared member initializer without an explicit instance of the class."
I have found very limited documentation on resolving this error. Pretty much every solution includes removing the shared reference instead of handling it.
When I remove the Shared reference and just make it private, the AutoCompleteExtender ceases to function completely (i.e. functions a a regular textbox). Here is my code:
If you notice that I am not referencing the @YRQ parameter in my query, that is intentional. I will replace the subquery with that parameter when I am able to get this working.

In a method, I want to call a shared function which its name came as a parameter. For example:
private shared function func1(byval func2 as string)
'call func2
end function
I get this error: Cannot refer to an instance member of a class from within a shared method or shared member initializer without an explicit instance of the class.
Partial Class _Default
Inherits System.Web.UI.Page
<WebMethod()> _
Public Shared Function ParseData() As String
Dim value as string = GetValue()
End Function
Private Function GetValue() as String
Return "halp"
End Function
End Class
I know it has something to do with the fact that the first function is shared and the second function should probably be Public as well but I don't fully understand the reason behind it. Probably not relevant but I'm calling the web method from some javascript.
My problem is that IIS does not support alert and message boxes.so i am using
Me.Page.ClientScript.RegisterStartupScript(Me.GetType(), "SetStatusText", "<script type='text/javascript'> alert('In catch...On page load.'); </script>")
but it is not working in shared function as i am calling shared function from javascript.
i want to show an alert box in the shared function.
below is my function
Code:
<System.Web.Services.WebMethod()> _
Public Shared Function DeleteCircular(ByVal cilr_code As Int64, ByVal status As String, ByVal from_period As Date, ByVal to_period As Date) As Integer
If status = "delete" Then
Dim conn As SqlConnection
Dim cmd As SqlCommand
Dim sql, connstr As String

In page behind classes I am using a private and shared object (list<client> or just client) to temporary hold data coming from database or class library. This object is used temporarily to catch data and than to return, pass to some function or binding acontrol. 1st: Can this approach harm any way ? I couldnt analyse it but a thought was using such shared variables may replace data in it ?2nd: Please comment also on using such variables in BLL (to hold data coming from database) where new object of BLL class will be made everytime.

I have a gridview that is dynamically created and have finished all but one problem - I need for my code that is within a Public Shared Function to access a textbox string - In the below I need myinput to return the string so that my query's can use the variable - the below shows: Cannot refer to an instance member of a class from within a shared method or shared member initializer without an explicit instance of the class.
If I remove the "Shared" the error goes away however it crashes other parts. (if I hard code the text then all works as expected)

I can access a module from code behind but not from the aspx page in inline VB code <% ... %>.
I know its got to be something simple but I can't seem to find the answer anywhere.

I have a function in a code behind file that's used to respond to a gridview event:
protected void GridviewEval(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
foreach (TableCell cell in e.Row.Cells)
{
if (cell.Text == "0") { cell.Text = "-"; }
}
}
}
It's currently in the code behind of a page and I'll be using it in other other pages.I would like to use the same code in other pages.When I cut and paste the function into a class,it's not working.
I'm new to C# and ASP and can't seem to figure out how to write a function to return a CSS Class name.
Here's what I have so far:
In "MyWeb.master" I have a line that reads:
<asp:HyperLink ID="HyperLink1" text="xxxxx"
cssClass='<%# MyCssStyle("ddd") %>'
NavigateUrl="http://www.RDRR.com/Catalog.aspx?TribeID=1"
runat="server" />
And in "MyWeb.master.cs" I have a routine within the partial class that reads:
public string MyCssStyle(string myInput)
{
myInput = "NavigationBarUnselected";
return myInput;
}
This code does not throw an error, but neither does it return a value. What have I missed?
