I have an user control in my default.aspx page
<uc1:FileGridVB ID="FileGridVB1" HomeFolder="~" runat="server" PageSize="5" />
Basically this user control list some files and folders in a gridview.
In my default.aspx file I have an ASP:Button tag with an ID of btnDelete. How can I reference this button from the usercontrol code behind file?

i have a usercontrol inside an updatepanel. when i click some button this usercontrol will be loaded. and the usercontrol itself has anither button in it. the problem is that the usercontrol code behind is never executed and when the button is clicked the usercontrol disappears.
View 1 RepliesI'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.

View 2 RepliesI 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 have a script written in PHP that does a number of things. I do not want to have to rewrite this in ASP.NET. I wanted to know if anyone knew how I can just call the PHP file from the code behind page after a button is clicked.
I cannot use javascript because things need to be added to the database and need to be successful in the function before I can call this php file. I do not need any of the php code to show up, I just need the php file to run and I need to add a parameter to the end of the URL.
i am using jquery upload plugin- jquery.MultiFile.js in my project to upload multiple files in this file now i need a confirm button when delete file so i changed code

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();

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.
