Web Forms :: Event Handler - Building Usercontrols For Something Like A WebSite Kit
Jan 18, 2010i've got a weired problem using an event-Handler in a Usercontrol I built. The Question to this is pretty simple. I don't get the "SelectedIndexChanged" Event on one of my ListBoxes which I turned to a Multiselection Dropdownlist with jQuery. It's a simple ListBox which should return the new values and should fire the "SIC" Event right? But it doesn't. I don't even get the new values as I try to change values and then read them. I spent more then 2 days searching for an appropriate answer but didn't find anything. As I tried to build a WebSite using some Usercontrols combined with AJAX I'm thinking about letting the Usercontrols out.

Web Forms :: ImageButton Always Calls Page_load Event?
Feb 11, 2011I'm using ASP.NET 3.5 and C#.I load an SqlDataSource into a DataView on my Page_Load event. My SqlDataSource queries arandom record from the database. On my page I have an ImageButton, which when clicked uses a Response.Redirect("AnotherPage.aspx + "random id from database"). My problem is that when the button is clicked it fires the Page_Load event before the Response.Redirect takes place in the button_click event. This causes the current data(the users "id") that I had pulled from the database to be overwritten with new data(a different "id") from the database. So essentially the the page is redirecting to the 2nd random id that is queried from the db after the button is clicked and Page_Load is fired again, not the original id. Here's my code, hope it makes sense.Here's my Page_Load:
[Code]....
Then my Button_Click Event:
protected void btn1_Click(object sender, ImageClickEventArgs e)
{
Response.Redirect("~/Profile.aspx?id=" + id1);
}
Can I put my dataview in another event or method so it's not called when a user clicks an ImageButton. Also I want the DataView to be repopulated on a postback/page refresh, just not on button clicks.
Web Forms :: Event Handling In PreRender Vs Page_Load?
Jun 29, 2010I have a GridView, here I am adding the LinkButtons at runtime to the GridView cells. I am also attacing an click event on these LinkButtons.
The issue is that when I populate the GridView from the Page_load the LinkButton click works, but if I move GridView polulation code in the Page_PreRender event the click event doesn't executes.
Code:
private void Page_PreRender(object sender, System.EventArgs e)
{
//does not fires the Click event of dynamically generated LinkButtons
GridView1.DataSource = getDataTable();

Web Forms :: UserControl Page_load Event Fires Twice Using LoadControl?
Jan 5, 2010I have a dynamically created user control which is accomplished usingLoadControl().
When I debug, the LoadControl call is called once, however the Page_Load inside the user control is called twice. On each occasion, the postback property is false, so it seems somehow the Page_Load event is called outright 2 times and nothing to do with any postback?
Web Forms :: TreeView TreeNodePopulate Event Called Before Page_Load?
May 20, 2010I have a TreeView on a page which I will populate the nodes on demand and a checkbox, and they are in the same updatepanel. I can dynamically add new nodes to this treeview. But when I click the checkbox which will cause a postback, the TreeNodePopulate is called before the Page_load and it will regenerate the nodes that was added before. I was very confused how could this be happened. Is this related with PopulateOnDemand and Expanded priorities?

Web Forms :: CheckedChanged Event Not Firing When Checked Property Set On Page_Load
Jul 21, 2010I have a web form with two RadioButtons, both use the same GroupName, both have AutoPostback enabled and both have an event handler for CheckChanged. I use tem to show/hide a Panel further down the form which is contained in an UpdatePanel with Conditional Update set and with both CheckedChanged events in the Triggers collection:
[Code]....
Now, the problem arises when I set the Checked property of either RadioButton in Page_Load, which results in the even not firing for the button which was marked as Checked (the event for the radio button whose property was not assigned does get fired). In fact, upon inspecting the source there was no 'onclick' attribute declared for the input element that was marked as checked in the Page_Load, whereas the other RadioButton did have the 'onclick' attribute properly set.
The layout of the form doesn't allow me to place the radio buttons within the UpdatePanel, so that is out of the question. Is the behavior explained above normal? am I missing anything? Both events fire once the assignment to the Checked property is removed from Page_Load.

Passing Variable From Event To Page_Load?
May 19, 2010I am thinking this is a pretty simple problem... but I can not get it to function.I just want to get the calendar control to change a date which subsequently modifies a database select statement. I can get the current code to process without error, but the variable set is always a click earlier. Of course, I want the variable to be set upon any change in the calendar control.
public partial class NewBusinessReport : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
[code]...
Does this make sense? I just want it so that when SelectionChanged gets fired the Calendar1SelectCommandDate passes the correct date to the Page_Load page. The error I get now is:"The name 'Calendar1SelectCommandDate' does not exist in the current context"I get that the variable does not exist in the context. That actually seems to make sense based on what I have coded; however, I try to get that variable established and I still seem to be headed in the wrong direction.Basically, I have four calendar controls, one for a date (period 1 start, end and then period 2 start, end). I want to set the program so any change in that date sets off a new Select statement into the SQL server.
