View 3 RepliesI have a page for webparts and have a usercontrol in the declarativecatalog. The user control had a gridview. I need to click (select) an item (row) in the gridview and change the selected value of the DDL in the parent (I guess this is the appropriate term) page.
<%@ Page Language="VB" MasterPageFile="~/MyStuff/MyStuff.master" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="MyStuff_Default" title="MyStuff" %>

If for example my userControl has a CheckBox called IsGreatCoder and the userControl is embedded in a main page (parent page).
I normally have gained access to the IsGreatCoder.Checked value in the main-page by exposing it through a public property that I have to manually write (say "IsAGreatCoder").
If UserControl is included in the main page as "userControl1", then I would access it as "userControl1.IsAGreatCoder".
But, I was wondering if there was anyway to declare the UserControl such that all the UI controls added to it were declared as being public, that way allowing me to gain access to the actual controls in the main page (the parent).
Essentially I would like to be able do something like userControl1.IsGreatCoder.Checked instead of having to implement a property.
The reason I want to do this is that I want to have access to many more of the check-box's properties and it would be a pain to implement each one as a public property.
I have an asp.net usercontrol located on on my aspx page. In the usercontrol there is a javascript function that I would like to fire everytime the page that contains the usercontrol submits to the server. (directly before this happens) Ideally I prefer to not have to write any code in the parent to make this happen, but I am not sure what the usercontrol may be capable of at this time. Can the usercontrol know that the page is submitting to the server and fire the function before this happens? Is there some sort of event that takes place here?
View 2 RepliesI wanted to know if we can pass values from Parent page (in this case from Default.aspx page) to the user control and maintain those values on subsequent "Add/Load" of user control.
So in short, if I click the "Add" button it loads my "webusercontrol" and also I am able to pass my default.aspx dropdownlist value to this dynamically loaded user control and assign it to a "Label or Textbox" which resides in my "webusercontrol", now the problem is that the value doesn't persists! What I meant is , when I click "Add" button again the "webusercontrol" gets loaded again perfectly but now all my "Label's" in webusercontrol has the new selected value from the default.aspx dropdownlist.
So say for instance I have a Dropdownlist in Default.aspx page with Values "Apple, BlackBerry, Nokia" and initial value to be passed is "Apple", I click the "Add" button, now my "Label" inside webusercontrol has the value "Apple", perfect! Next when I click "Add" button again and select a different value to be passed this time say "BlackBerry" now I have 2 webusercontrol loaded on the page, so that means I have 2 "Labels" with different ID's, but now my first Label initially had the value "Apple" because that's what I had passed and now when I passed the value "Blackberry" both the labels of my webusercontrol has the value "BlackBerry" instead of one being "Apple" and another "BlackBerry"
Is there a way to resolve this issue? may be Dictionary List?
My default page has a usercontrol that opens up a modal to allow updates. When the user closes the modal window I want the usercontrol that resides on the default page to update.
it looks like this
default.aspx has userControl1
user can open up a modal from userControl1
modal has textboxes for updating
when user closed modal I want to then refresh userControl1 on the default.aspx page without reloading the entire default.aspx page.
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();
I have a User Control which has a dropdownlist.
Now i want this dropdownlist value in parent page in a label control.
whenever i change dropdownlist value label value should be change.
How can i do it?
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
I've created user control named test.ascs with one textbox. Now I added this user control in my default.aspx page. How can i access that textbox value from my default.aspx page?
View 3 Replieshow to open a popup window and return values to the parent page

Senario: Masterpage with a UserControl and a child ASPX page
In the past when using this senario I've used an Interface as a way to pass a value from the UserControl (embedded in a master page) to the masterpage code behind then consume that value in the child aspx page.
My question is now that asp.net 4 have arrived is this still a good way to achieve this or is there another or perhaps better way to do it? I've read somewhere that perhaps "delegates" is perhaps another route to take.
In my website I have two forms: parent form and child form(dialog box). Their expected behaviour is like this: if clicked on 'show' button on parent form, a dialog form opens that displays a gridview. In dialog form, if clicked on 'select' button it closes
itself and returns value in selected row back to parent form.
To achieve this I write following code (.cs) : in parent form:
void ShowBtn_Click(object sender, EventArgs e)
{
StringBuilder jScript = new StringBuilder(); [code]....
Now problem is: the code in parent .cs works fine, it opens the dialog properly. But when clicked on 'select', instead of returning back to parent, it opens the same dialog again in new window. This newly open window says "Done but error on page" at left bottom.
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?

How do I set the selectparameter of Objectdatasource in usercontrol from dropdownlist in parent page?I tried the following but when I select a new value in the dropdownlist it does not change the data from the initial page load

I have a partial view that is rendered on a view. That partial view has textboxes in it. The user can enter values into them.
I need to put all the values from the textboxes in my partial view into an array, and then give the view (the parent page rendering that partial view) access to that array.
Can anyone add a complete input about how to create Parent Property with multiple child properties or in short nested properties.
Example: Style tag: which has properties like font, color, display... etc? which accept objects and its value.

As soon as Rainbow property is typed, user should get intellisense for list of number of colors. Then accordingly user can select list of those colors and assign a value to them.

How can i get the values from my User-Control?
I am trying to write a simple application that will allow a user to pass a value from the parent page to a textbox in an IFrame.
Parent Page will only contain 3 controls (label, textbox, and a button). Once a user fills in the txtbox and then clicks the button I want the value that was put in the textbox to be sent to a textbox within an IFrame.
IFrame will contain a label, a textbox, and a button. Once the value is passed from the parent's textbox control to the iframe I want to also fire a button event in the iframe that will simply be:

I am not worried about passing the value back to the parent page. My goal here is to create a testing application for my website.

i have a usercontrol with two public properties
public DateTime fromdate
{
get;
set;
}
public DateTime toDate
{
get;
set;

I am setting this values in my code behind. After setting the values i want to reload the usercontrol so that it fires a get method which will use these dates ...how will i reload the usercontrol
this is about ASP.NET, ViewState, UserControls and loosing the values of my properties. It is an classic question by know, I know, and even though I have searched here and on Google for a resolution to this problem, I havent succeeded. On the contrary, the more I test different things, the less I understand it seems.
On top of this I am using ext.net and their so called DirectMethod's but I dont think that has much to do with this problem. There are numerous questions I have and I hope that this text will be fairly readable and understandable =)
The UserControl
I have a UserControl, Customers.ascx, that contains some Properties. The "most" important is *_CustomerId*. The _CustomerId is set in code-behind, in ext.net's "DirectMethod" like this (code below from the Page Customers.aspx):

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 currently have 2 x ASP.NET 3.5 web applications in IIS7 (lets call them WebParent and WebChild).WebChild is nested within the WebParent listing in IIS7 and is set up as an application (rather than just a virtual directory within WebParent). Both currently use their own (Classic) application pool.Both WebParent and WebChild have their own fully defined web.config files in their own root directories.
