I have a user control which I load dynamically using LoadControl. In this UserControl I have a button with assigned OnClick event, but when I click that button, the event is not fired. I'm populating the user control in UpdatePanel's Load event (I invoke __dopostback from JS).

Here I load user control in the page

I have a nested GridView that is placed inside a ListView. The GridView renders perfectly fine with all the entities that are bound inside its datasource.
Each record in my gridview has two buttons - 'delete' and 'edit'. The issue that I am having is that the methods wired to each of these buttons never get fired.
I think the reason for this behaviour is because my ListView's data binding happens only on the first page load, and not on every subsequent postback. As a result, when a postback happens, the events of the nested gridview are never wired up again - hence my methods are not getting fired.
Here is what my code [simplified] looks like:
[code]...
I tried modifying the above code and removing the "!IsPostBack" clause, and the events actually got fired when a button inside the GridView was clicked. However, I do not feel comfortable doing a databind on every postback and think there should be a better solution than that.
I have a table control that I am building dynamically and inside one cell I am placing a LinkButton inside it and wiring up an event. Although the event for the LInkButton never fires.

This is page load
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)

But in my ascx.cs when IButton1_Click is trigered My name is null
private string _sname;
protected void Page_Load(object sender, EventArgs e)
{ [code]...
So I've got a databound grid view within a UpdatePanel.
the user can change the data within the gridview then click a save button to update the data within the database.
However in order to know which rows have been changed I have a textChanged event associated with each textbox, but the event isn't being fired.
Here's the ASP code:

View 2 RepliesI have a page with an UpdatePanel with a UserControl in it. That UserControl contains a GridView with a nested UserControl that seems to disappear when the parent UserControl is rebound. I cannot for the life of me figure out why the child UserControl disappears. The code works beautifully on the first load, but any partial postback causes the "Pick" UserControl to disappear.

I have a UserControl, which contains another UserControl with Button. I want to add an event to that button in first UserControl (parent). I tried to do:
void Page_Init()
{
var btn = ChildControl.FindControl("SearchButton") as Button;
btn.Click += new EventHandler(this.SearchButton_Click);
}
but btn is null. How can I do that ?

I'm facing a weird issue...My button events are not firing :(I'm using the 3.5 .net framework and I've already tried to run aspnet_regiis -c, clear the browser temp files, use windows integrated authentication, but nothing works...this is the cenario:
- windows server 2003
- app migrated from .net framework 1.1 (which was working fine) to .net framework 3.5
- IE8
I have the problem that when i´m adding my usercontrol to my default page the events do not fire. I already know that I had to add the usercontrol as soon as possible to the lifecycle, but I can´t because I know the number of buttons after clicking on my default button.
code:
my default.aspx.cs page
protected override void OnInit(EventArgs e)
{
if (!IsPostBack)
{
addPruefstation aP = (addPruefstation)this.LoadControl("addPruefstation.ascx");
aP.ID = "ucPruefstation";
Session["ucPruefstation"] = aP;
}
base.OnInit(e);
}
protected void bApply_Click(object sender, ImageClickEventArgs e)
{
int anz;
Int32.TryParse(((TextBox)tablePruefstand.FindControl("tbPruefstandstationen")).Text, out anz); //here i´m getting the number of buttons
Session["anzStation"]=anz;
addPruefstation aP = (addPruefstation)Session["ucPruefstation"];
aP.anz = anz;
Session["ucPruefstation"] = aP;
phPruefstation.Controls.Add(aP);
}
my usercontrol.acsx.cs:
public int anz;
protected override void OnInit(EventArgs e)
{
for (int i = 0; i < anz; i++)
{
tcButton=new TableCell();
trPruefstation = new TableRow();
tcEmpty = new TableCell();
tcLabel = new TableCell();
tcTextbox = new TableCell();
tcLabel.Controls.Add(new LiteralControl("Anzahl Leaks"));
tcTextbox.Controls.Add(new TextBox() { ID = "Leak" + i, Text = "0", AutoPostBack = false });
ImageButton imgButton = new ImageButton() { ID = "" + i, ImageUrl = "~/Img/1rightarrow-256.png", Height=15};
imgButton.Click += new ImageClickEventHandler(imgButton_Click);
tcButton.Controls.Add(imgButton);
trPruefstation.Cells.Add(tcEmpty);
trPruefstation.Cells.Add(tcLabel);
trPruefstation.Cells.Add(tcTextbox);
trPruefstation.Cells.Add(tcButton);
tablePruefstation.Rows.Add(trPruefstation);
}
base.OnInit(e);
}
void imgButton_Click(object sender, ImageClickEventArgs e) //this event never be fired
{
throw new NotImplementedException();
}
How can I stop Search engines firing events.....
I have a button that adds a product to my shopping basket. it has a postbackurl="../shoppingbasket.aspx?productID=1" when the page is loaded I get the querystring (ProductID) and add it to my database. Well I have been watching the database and I can see that in 1 day the whole of my product range has been added to the shopping basket, not only that but every time it fires the event it creates a NEW basket thus messing up my shopping basket ID's.
So my question is, I want the search engines to index my product pages, BUT I do not want then to add to my basket ( i.e. firing the postbackurl ) I have tried may things like rel="nofollow" adding the URL to my robot.txt. I don't really want to use recaptha as I have do before and have many complaits about it.
I am in a deep deep trouble because I am trying to use web parts in my project,I have implemnented custom provider for personalization(coz, I am using MYSql as a database).I am using three web part zones and each zone hve more than three controls and whenever I try to drag and drop the parts from one zone to other zone, for the first time the droped element successfuly runs but after then if we again try to drop another element from other zone to this then the already dropped element goes to its original place from where it is dropped,The 2nd problem is that close and minimize verbs are not firing well, e.g if there,My provider personlaization class is as,

I have a usercontrol (ascx) with a DropDownList placed on a MasterPage. It has AutoPostBack=true. I created a SelectedIndexChanged event for the dropdown on the usercontrol, but it does not fire when seleted item changes. The PostBack fires and both current page as well as MasterPage are reloaded but the SelectedIndexChanged is not fired. How can this event be trapped?

I have a main formview which contains another formview. In the second formview I have a section that needs to insert/update. I want to access this formviews events for example I can access the main formviews item inserted event in the code behind:
FVInvoiceHCPAgreement_ItemInserted
I can't choose the nested formview events in the code behind
ie. FVInvoicePaymentInfo_ItemInserted
I have tried adding the ItemInserted event in the .aspx page
i.e. onItemInserted = "FVInvoicePaymentInfo_ItemInserted"
but for the handles clause it can't see FVInvoicePaymentInfo.
I've dynamically created 3 checkboxes as you can see in the code below. I also wrote an event handler below. When I run the code, the 3 checkboxes show up, but the event handling does not work right. Whenever there is postback from any of the 3 checkboxes, Label1 reflects the state of checkbox #3, no matter if I toggle checkbox #1 or #2. I put the code I have under Page_Init into Page_Load instead, but makes no difference either way.
The bottom line is, I want the event handler to know exactly which of the 3 checkboxes is firing the event so that Label1 can reflect that.

I have a user control that has an event that checks if a textbox is empty and does other processing...this event would also set a publ;ic property on the user control to a boolean value.
1) On the host page/parent, I want to click a button that will set off the event explained above.
2) Also, how do I reference the user control on the host page?
I have a nested listview (orders with products)I want to add functions to update products and option to add new products update func works fine. wheni try to insert new record, itemcommand and iteminserting events are not firing. Im registering dynamic script using the below code

+ ItxtPrice.ClientID + "," + IddlInstallType.ClientID + "," + "empty" + "," + ItxtQty.ClientID + "'";
imgPicker.Attributes.Add("onclick", "LoadLookupScreen(" + clientIDs + ")");without the above code, itemcommand event works fine. when i add this script register itemcommand event was not firing
I have a webUserControl that is nested inside of another dynamically loaded usercontrol. The nested user control (harddrive) can have multiple iterations, see below for hierarchy When a postback occurs the value in the dropdownlist inside of the nested userControl is saved, but the data in the textboxes is lost. any ideas?
Hierarchy:
insert.aspx
[^--loads] asset.ascx
[^--- loads] harddrive.ascx -- there can be multiple instances of this control inside of the asset.ascx user control

I've been reading up on the problems with dynamically created controls and how they have been solved. The posts I have come across are creating the controls in a panel or some other open place. I can't seem to get my checkbox to fire the event from inside a gridview. below is the code behind from inside the GridView PreRender event.
[Code]....
..And the Checked Event..
[Code]....
So after all this, nothing happens. I get the postback flash but my command inside the checked event doesn't fire.I tried putting the dynamic creation of the checkbox in Page Load with no effect.. I think because I can't place the checkbox inside the GridView under page load.
I'm currently working with a repeater which has some number of drop down lists in it determined by how many items are databound to it. I wanted to add an event to each of these drop down lists in the scenario that a user changes the selected index.
Here is what I have for the repeater (Note that I am doing all of the databinding in the codebhind.):

I am setting the OnTextChanged event here, however I did some experimenting with using the different events. I found that my method will not run when I am using the OnTextChanged or OnSelectedIndexChanged events. However, if I use some other events like OnLoad or OnPreRender, the method I have it set to actually runs. So in short, why is it that when I put this drop down list in the repeater only SOME of the events seem to work?
