This is page load
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{ [code]...
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]...
I have a custom control in an aspx page that has a property named Size
public int Size
{
get { return Convert.ToInt32(ViewState["CreativeSize"]); }
set { ViewState["CreativeSize"] = value; }
}
This property is set in the aspx page to a value lets say 500 during a postback called by a Button control that is in the page (not in the custom control).
I also have a button inside the custom control that raises a postback like this
protected void btnUpload_Click(object sender, EventArgs e)
{
if (fuBannerfile.HasFile)
if (fuBannerfile.FileContent.Length / 1024 > this.Size)
;//code here not important
}
When this event is called the "this.Size" property is 0. I also noticed during debugging that during Page_Load of the page, if i access the property like this:
int size = customControlId.Size;
the property is set to 500. But after that when the debugger reaches the event inside the control the property is 0.
I created a customDropdown usercontrol with Events and It worked fine.
Now I stored the path of the ascx file in the database table and i want to Load the ascx file and handle the Events dynamically in an aspx page.
To Load the usercontrol and access the public properties and method, I need to know the object i am trying to load, right?
For Example
FeaturedDDL c = (FeaturedDDL)Page.LoadControl("~/FeaturedDDL.ascx").
But I dont want to hardcode objectType "FeaturedDDL", coz i dont have that stored in my Database field.
Since I am loading the usercontrol by getting the path and name of the usercontrol from the database table,how will I know the ObjectType at that time?
How to accomplish that and also how to handle the events for these type of situation?
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();
}
I have some user controls which have properties which need to be set from a form on the page
<uc1:MyPlugin
ID="MyPlugin2"
runat="server"
Property1="Hi"
Property2="0" Property3="<%=Property3%>"
Property4="<%#Property4
%>"
/>
Property3 and Property4 anre both public properties of the page I am on and the user control
Currently the code complaing about Property3 saying it cannot create an object of Int32 from '<%=Property3%>' and Property4 always gets set to 0 (the default)
I do not wish to use the c# code to set these values as this Plugin will be deployed with a CMS which I have no control over

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?

how to access "custom usercontrol's properties" while the usercontrol itsef has been added programaticly by code.
im creating site with usercontrols. I have repeater, inside it is another repeater with usercontrol. My problem is passing BindedValue to usercontrol.Bindings works fine and binds the value i need but it cannot pass the value to usercontrol. When i type it manually it works, when i bind it, it passes null (!).I've tried get,set, functions (ondatabound, onload, oninit), accessing control from code with no luck. Ive read and tried to do all the google solutions but with no luck. (even with creating usercontrol inheritance)
View 5 RepliesThere are 2 UserControls UC1 and UC2, and there is one more class C. I want to share the same instance of c in both UserControls. I know that this can be possible with properties in both UC's and by registering UC2 in UC1 or vice versa. But I want the solution to be loosely coupled. Any best possible way without touching the Actual Page (which hosts UC's)? So i need some best possible way between UCs transfering C.

How can I write the C# code (aspx) to initialize the user control with some default property values? I mean where/which event? I have a user control with a gridview that I bind on container page. On page load of the container page I bind the data. I tried writing the initialization code in initproperties but it didn't work. Please suggest where can I set the default values for my usercontrol?
Edited:As suggested by DOK.. I already have a property and I change width of one of the DIVs. Here is the code that is not working.

this works only if I set the width on calling program. Otherwise the default value of style="width: 105px;" is not added.

I have a div inside a user control that is displayed by the user after some event. I want to hide this div when user clicks anywhere elese on the page but not on the div (or not on any element that is inside the div).
If it wasn't a user control I could use body's clieck event to check the target, but because this is usercontrol that is hosted by other page I can't just "play" with it's elements. How can I achieve that without using body of the hosting page?
I have several usercontrols which are loaded based on business logic.However, all of them have webcontrols whose selected/entered value needs to be accessible in parent page on an event.Since there can be any combination of UserControls, I do not want to load all the UserControls in the Parent Page, since they are heavy.
I would like to load only those controls which are supposed to appear on the page, yet access the value from the usercontrol which caused the postback. (I would rather not access using Request.Form) (ViewState is open, but unsuccessful to store value in parent page's viewstate in onClick)Here is a sample scenario
Page: Home
Dynamically Loads: UserControls1
UserControls has TextBox tb and Button btn, causing onClick
When btn is clicked, I want to get value of tb in parent page on PostBack, Page creates UserControl2
How can i call a page method after a usercontol finished his method / fire a parent page method from inside the user control insted?
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.

I 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.
