I have a simple Tabcontainer with 3 tabpanels. I want to load some content to the different tabs the first time they are clicked (selecting the tabs). I have tried using Protected Sub TabContainer1_ActiveTabChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles TabContainer1.ActiveTabChanged but that only works, WHEN there has been changes to the content.
So my question is: How do I raise a server side event like loading a droplist when the tab is clicked?
I am using ASP.NET's server-side validation. In the page_load event I'm calling Page.Validate(), and if Page.IsValid is not true I'm then polling the controls to figure out which ones are not valid, and then determining what actions to take.It would be much easier if each control would raise an event as validation fails, allowing me to take action for that particular control. I'm very much a naive programmer when it comes to validation, but is there a way to extend these controls so that a validation error raises an event?
Working on a DNN website. Long time VB programmer new to ASP and Web Development.
I have a page with 2 modules on it one to select records and the other to show records details. there is also an add button on the select module for adding new records. the detail module has a tabcontainer with 5 tabs on it and if the user is adding a new record I want to disable the first tab. At all other times I want the user to have access to the first tab. The user clicks a button that uses OnModuleCommunication to start adding the new record. All my code is server side so when they click the button I clear all the fields and enable them all for editing but I have not been able to set the tabcontainers tab to enabled=False
[Code]....
and if it is in the correct location I do not want the button on the page to be seen like it is I want to call it from the server side so the user has no choice.
How can I acheive that? If it's not possible, what other alternatives do I have? The most important requirement for me is to allow the user to remove the data by clicking on it.

I have a user control that contains a repeater. We have added some paging and sorting into the user control and it all works well.
What I need now is a nice way to catch the OnItemDataBound event of the inner repeater and then bubble it up to be accessible directly from the user control from within the page.
We have tried catching it and then declaring it in the user control but it just won't work.

I need to generate a gridview with dynamic columns, on each cell I need a button that inserts-deletes a relationship in a database. The relationship is of course between what is represented by each column and row. I decided to use a gridview and create templatefields which I add programmatically to the table. I successfully got to that point but when i decided to raise a click event from the buttons or a rowcommand from the gridview I could not do it. I´m looking into doing this with button fields right now but I´m curious on how this can be accomplished?
