Hi,

I use grid view in my own module to list certain entries from db.
One ObjectDataSource with one parameter is used. Parameter is being dynamically changed by clicking on LinkButtons, which are programatically added to page in a placeholder. Their names are loaded from DB (different ObjectDataSource).
Each LinkButton has its CommandName = "Filter" and CommandArgument = row("id_cat").toString

Everything is placed in Page_Load method.
Filter method looks like this:
Protected Sub Filter(ByVal src As Object, ByVal args As CommandEventArgs)
  ObjectDataSource_Tasks.SelectParameters.Item("UdSubType").DefaultValue = CType(src, Control).ID
  Me.GridViewUdalosti.DataBind()

But....
I've placed breakpoint in the top of the Page_Load method and debugger stops here only first time the page is loaded! Never more again...
After clicking one of the LinkButtons PostBack is called but breakpoint placed in Filter method is never achieved and ObjectDataSource parameters are not changed :(

What am I doing wrong?

Thanks a lot for advice!

Thanks a lot!
Now even breakpoints work properly.

But I'm still doing something wrong...After clicking any linkbutton, Page_Load is called and THEN Filter method. DataBind is called inside it but the content of the page is previously generated in Page_Load method and it is not updated after Filter method is called.

How can I do this, please?

I've used this guide while developing this module. Now I can see, it has been updated (was GuestBook module before).
I don't use any ModuleId parameter within my db tables or stored db porcedures  so I don't uderstand why should I place this method into my code. If I do so, it's called after every Page_Load but I don't know what shoul I place inside it :(
