Forms Data Controls :: CheckBox Checked Changed Event Is Firing For Every Control Event?

May 8, 2010

I am facing one strange problem,I have a gridview in which the last two columns have checkboxes and on those checkboxes click event I am doing some database operations.I also have one checkbox that is outside the gridview which actually shows or hides some of the gidview columns.This was all working well but now I have shifted that grid to a user control because I have to use it in two pages.The problem now is,When the page first loads and I click the check box or any control in the page that is outside the grid then it works perfectly.But once I click any of the check box within grid view column then its behavior chages, now even if I click the checkbox that is outside the grid then also the checkbox_CheckedChanged event of the checkbox that is whithin gridview is fired.That checkbox event then behaves something like a page_load event that is called for every page load and for every event with in the page after it is called once.

Web Forms :: User Control Needs To Fire Event In Aspx Page?

Jan 31, 2010

I have a need to improve the asthetics of the standard buttons .net churns out. I am fully aware of how to do this using css but I can only really style the button if I add a span element inside the button. Luckily the link button allows this so I have got the following which for usability i have put inside a user control.

<linkbutton><label>button text</label></linkbutton>

I have exposed elements so that I can set values from within my aspx.cs page, these are text, command name, command argument, ccc class etc.

As it is a generic control, I have added OnCommand='Button_Click" which fires the event in the control itself. The Button_Click event calls a method ButtonControls passing associated command name and arguments across. ButtonControls uses the name to call the appropriate function.

As these are all very generic buttons, so far so good, but I have a need to trigger button events that may not be generic i.e on a control I have buttons that do something very specific to that control. I also have a requirement to call functions which relate to specific controls on the aspx page. I have created a user control which encapsulates the link button control.

Click triggers > Button_Click > ButtonControls > MethodToCall

sometimes I don't want to call Button_Click just an event on the aspx page itself rather than my generic button handler.

Event Handler For The Activity Control In The Markup Of The Aspx Page?

Jun 24, 2010

I have created a web user control called Activity. I have defined a public-facing event on that web user control called OnActivityDelete. There is a delete button in the Activity control. When the delete button is clicked, the Activity control fires the OnActivityDelete event. I am using this web user control in a repeater. I assign an event handler to the OnActivityDelete event on the repeater's item data bound event. When I click the delete button for the Activity control, the event fires from the Activity control, but it never hits the event handler in the page that's using the control. (I have stepped into the code with the debugger and confirmed this behavior).

My suspicion is that this behavior has something to do with the fact that the event handlers are added in code behind when I bind the repeater to a datasource, which I only do if the page is not posting back.Is it possible to define the event handler for the Activity control in the markup of the aspx page? If so, will this solve my problem?If not, do I have to bind the repeater and hook up to the events every page load in order to solve my problem (this works, I just tested it), or is there some viewstate trick to getting the events to persist? Markup of Repeater on page:

<asp:Repeater ID="rptrActivites" runat="server" EnableViewState="true">
<div class="activity">[code]...

Page's code behind:

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

If Not Page.IsPostBack Then
GetActivities() [code]....
