I am trying to dynamically load query form as a user control and build a sql statement based on user selection. I have a dropdownbox for Tablename, FieldName, ConditionalOperators and Value Field. Once the user makes a choice and causes a postback I loose my QueryForm (UserControl) and the selection Changed event never gets fired. I tried reloading the QueryForm on Page Init, still no luck.

I've a ASP.Net page (Default.aspx) which will load UserControl (ucontrol.ascx) dynamically into an UpdatePanel. By using UpdatePanel, we believe we're able to prevent the entire page to be posted-back.
My problem is, within the UserControl, we have some form controls, such as inputs and buttons; after the UserControl is loaded, clicking on any button inside the UserControl will cause the UpdatePanel to be blanked. During the investigation, I found that, breakpoints within the Button1_Click() in the code-behind for the UserControl is never reached. Please reference to the code below, this references to [REFERENCE]1.

I have ASPX page named ArtifactReporting.aspx where I have 3 linkbuttons. For each button I have 3 different UserControls to be loaded dynamically. So I have written for each click
UserControl uc = (UserControl)this.LoadControl("<ASCX page name>");
divArtifact.Controls.Add(uc);
Now in one of the ASCX page I have a server side button. When I click on the button, the content of the ascx is going off, which is correct, because the page post back is happening and in Page_Load I have not written anything that will load the ASCX page.
how to go about this? I need if I load an usercontrol dynamically, I should be let the users carryout operation that usercontrol.
In a page , when I click a button 'showDialog' I am loading the user control dynamically in a dialog. I am linking to the event in the user control as explained below. The parent page is not receiving this event.
Button_Click(){
UseControl1 gc = dlg.LoadContent(:UserControl1.csx);
gc.CausePostback += new EventHandler(execute_CausePostback());}
execute_CausePostback(){
In UserControl class after clicking the submit button
Submit_Click(){
saveRecord();
raise event CausePostBack();
When the user selects an "account" we dynamically create a linkbutton with the selected dates. However, the linkbutton onclick handler doesn't fire when the button is clicked.
Dim linkBtn As New LinkButton
linkBtn.Text = "blah"
AddHandler linkBtn.Click, AddressOf linkButtonHandler
linkBtn.ID = panelDatesRencontre.Controls.OfType(Of LinkButton).Count
panelDatesRencontre.Controls.Add(linkBtn)
ScriptManager1.RegisterAsyncPostBackControl(linkBtn)
Dim Trigger1 As New AsyncPostBackTrigger
Trigger1.ControlID = linkBtn.ID
Trigger1.EventName = "Click"
UpdatePanel2.Triggers.Add(Trigger1)

I need to load a web user control dynamically.
Looking at [URL] it states that the page lifecycle events are not fired.
I thought I might be able to raise the events through reflection. I cannot figure how to fire the events, am I missing something?

It is a header with two columns: On left column there is a TreeView, and on the left there is nothing (now there is a label to try the thing that I want to do).
When user select a node on treeview a click on Edit button. Code for click event is:
protected void Edit_Click(object sender, EventArgs e)
{
if ((DestinationTree.SelectedNode != null) &&
(DestinationTree.SelectedNode.Depth > 0))
{
BaseControl baseControl = new BaseControl();
UpdatePanelRight.ContentTemplateContainer.Controls.Clear();
switch (DestinationTree.SelectedNode.Depth)
{
case 1:
baseControl = (BaseControl)LoadControl("~/DynamicControls/Control1.ascx");
break;
case 2:
baseControl = (BaseControl)LoadControl("~/DynamicControls/Control2.ascx");
break;
case 3:
baseControl = (BaseControl)LoadControl("~/DynamicControls/Control3.ascx");
break;
}
UpdatePanelRight.ContentTemplateContainer.Controls.Add(baseControl);
}
}
Depending on node selected depth is going to load a custom control dynamically. It works, but when the user select another node on treeview, the original label is reloaded on right column.
I have created a user control that contains two asp calendar controls. I need to add this user control twice on the same asp page, let's say for Check in date and Check out date. Since the two are conflicting to each other when I add it twice statically, I now dynamically add them on button click so that each time only one control is loaded. The problem is, when I select a date on a calendar, it seems that the selection event is not happening at all. Of course, I am not getting any date.
View 4 Repliesim using an update panel and my web form consists of textboxs and combo box, my problem is that when i click the button save for the first time, my page simply postbacks and the event save wouldnt fire, click it the second time and poof save will execute.. I notice that it is caused by my dropdown box and textbox autopostback function, i need to set this to true since i need to execute another function that will disable the dropdown when the textbox is filled and vice versa,set this to false and save will function normally..any ideas how to fix this?
here is the code for that.
<asp:DropDownList
ID="ddNewLocation"

AutoPostBack="true"

For some reason the first time I click this button, the code is beeing fired. When login credentials are wrong, a message shows up. THen, the user inserts the right credentials. After clicking the 'cmdLogin' button, nothing happens and the old (wrong) values are beeing filled in inside the textboxes. This behaviour occured to me after switching to ASP.NET 4.0.

I have a aspx page, default.aspx, with an user control in it. Inside the user control (UC 1) there is a DataGrid. When the DataGrid is loading data with ItemDataBound, I need to dynamically load another user control (UC 2) for each row in the DataGrid. UC 2 has a Button ( BTN )with an eventhandler associated with it in code behind.
User control loading is fine, and the Button, BTN, is there. However, when I click the Button, the eventhandler is not reached, not firing, even though the page does postback. I googled for this issues, and I know the dynamically loaded user controls need to be loaded every time the page is postback. In my case, it needs to be loaded each time the datagrid is doing ItemDataBound. I did it and even hook up the eventhandler with button click event each time when the user control is dynamically loaded. I set EnableViewState to true on the Page and controls.
The following is part of the code from UC 1, AcctPaymentDetail is UC 2 in the code.

And the following is UC 2 the is being loaded:

I have a situation where I dynamically load one of twenty user controls at a time in an ASP.net web page. Based on much reading I've done, I understand that I am to reload the user control upon postback via the Page_Init event handler. This I've done and it seems to work fine.
But now I would like to wire up assorted controls in the user controls such that when the value of each is changed, an event is fired and the web page is notified. Here's an example of how I'm doing that:
userControl.NewData_Handler += new EventHandler(UserControl_NewData_Handler);
There's a problem though. Because the user control is being done in Page_Init (ie. before Page_Load) I don't believe that a line of code such as the one above can function yet.
So I'm wondering what the best practice to do this is. It occurred to me that perhaps I could execute the line in the Page_Load event handler but I'm not sure if that's correct or not.
