I have created a web user control I want to change the iframe' src value when the user click on the link but the problem is that I dont have access to iframe inside the page from web user control I think there is a way because my control is in the page they have some relation perhaps I like to find something like this :

I have user control in the master page. user control code behind page having public property called SetValue.
Now I want to set the value from content page .
I've got a web site that has a master page and that master page (mpMaster that has a user control ucControl1) which has a sub user control (ucControl2), this user control has a property which accepts a value. Now, I have a page that uses the master page
and on this page I have another user control (ucPageControl), I need to find a way of setting the value in ucControl2 from ucPageControl. Is this possible at all?
I have on dropdown that show hide user control. In the user control i have Ok and Cancel button.
When the dropdown change i want to apply ValidationGroup on the Ok button that is inside UserControl.
I have an asp.net usercontrol which represents a "popup" dialog. Basically, it's a wrapper for the jQuery UI dialog which can be subclassed to easily make dialogs.
As part of this control, I need to inject a div into the page the control is used on, either at the very top or very bottom of the form so that when the popup is instantiated, it's parent is changed to this div. This allows "nested" popups without the child popup being trapped inside the parent popup. The trouble is, I can't find a safe way to inject this div into the page. A usercontrol doesn't have a preinit event, so I can't do it there, and calling Page.Form.Controls.Add(...) in Init, Load or PreRender causes the standard exception "The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases."
I thought I had found a solution by using...
ScriptManager.RegisterClientScriptBlock(Page, Me.GetType, UniqueID + "_Dialog_Div", containerDiv, False)
... which seemed to work well normally, but recently a coworker tried putting an UpdatePanel inside the dialog and now she's getting the error "The script tag registered for type 'ASP.controls_order_viewzips_ascx' and key 'ctl00$ContentBody$OViewZips_Dialog_Div' has invalid characters outside of the script tags: . Only properly formatted script tags can be registered."
How are you supposed to add controls to the pages control collection from inside a user control?
I have a asp.net webpage which is using an Master page and contentplaceholder.
My Req: I want to access the control name through javascript.I have tried to use 'document.forms[0].elements[i].name' but its giving an error since my page there is no form.Only master page and contentplaceholder.
I have looked everywhere for how to do this and all I come up with is threads describing how to expose public properties. I have a USER CONTROL in my Master page. It is a search box with a text box and a dropdown for search type (last name, account number, etc) and a search button. When the user clicks the search button, I open a new page that displays the results. How do I pass the values from the USER CONTROL search fields to the new page? I would post code, but I have nothing to post yet since I don't know where to start. I have tried exposing the public property of the user control, but I don't know how to retrieve those values on the results page.
View 7 RepliesI am working on a page called Edit.aspx and on that page is a User Control.
Note: I need to access the User Control from a button that is on the Edit Page. Once I get a handle of the User Control then I need to access a DataList on that user control and finally I need to get the ID of a dropDownList
on the User Control
This is all the code I have,Goal: From the Edit page I want to drill backwards to the UserControl/DataList/DropDownList
'Geting the user control
Dim ctrl2 As UC_SiteTemplate2 = CType(Page.LoadControl("~/UC/SiteTemplate2.ascx"), UC_SiteTemplate2)
'accessing drop down list from user control
Dim xListNumber1 As DropDownList = New DropDownList()
xListNumber1 = ctrl2.FindControl("DDLOrderList1")
There is one user control say uControl.ascx. This has a public property Message. There are 2 aspx pages Default.aspx and Home.aspx which has the user control uControl.ascx. When a sumit button from Default.aspx is clicked some action takes place and the value for Message is set and then execution is redirected to Home.aspx. In Home.aspx the value for Message is lost.
Is there anyways that the value of Message is retained for both the aspx pages?
Am not sure why I cannot access my Label control which was inside the Panel and the Panel is inside the DataList
[Code]...
but when I tried using "lbl" in Page_Load, it seems it cannot find the control?

that code returns Object reference not set to an instance of an object.

output:

I have an EDIT.ASPX page and on that page I have some labels and textboxes and a user control. I listed all the related codes you can have a clear picture - not all of the codes are given me a problem. ONLY ONE.
HELP ---> On the Uer control (SiteTemplate2.ascx) I have a DataList that is being populated by the database and that works fine. I have a
CHECKBOX on the user control page each time the user check the CHECKBOX the user control content totally disappears from the EDIT.ASPX page. There is no error message -- I believe this is a post back error but I don't know how to fix it.
Goal: Each time the checkbox called (CHKBSideBar) is clicked on the user control page all of the page content should stay in place that include
EDIT.ASPX Page and the refeneced USER CONTROL. I should be implement a CheckedChanged Function without either of the pages lossing DATA. I need to be able to access post back event from the user control of the Edit.aspx page. When the user click a box on the user control page how do I keep the same Page_Load event on the edit page. I need to reference the Edit page from the user control.
Note: The edit page loads the user control (SiteTemplate2.ascx)SEE CODES BELOW
I know this is a lot and thank you in advanced for your help. I tried to include all the pages that are key players. I must user the user control bacuase the user can select different template so eliminating the user control is not an option.

I have a User Control with a multiple number of link buttons.
What I want to achieve is to change the Background colour of one of the link button control in the page load event of one of the pages. I am finding it difficult to access the link button in user control .
If the answer to this question exists somewhere, I'm no good at searching for it. This is sort of a simple question, the response being two parts: (1) is it possible? (2) if so, how?
I've created a web user control for my site's footer. In my web.config I have it registered like this:
[Code]....
Then, within the pages on my site, I simply insert it like this:
[Code]....
But obviously, that didn't work. I get this error: The type or namespace name 'FooterControl' could not be found (are you missing a using directive or an assembly reference?)
So I'm really not sure what to do at this point. I can put all of my code in the ASPX file and make my life easier, but I would kind of prefer not to.
I have to access the parent form's controls inside an event handler method on my user control's code behind.
View 4 RepliesI have a web user control that represents a simple message box. It is used to display simple messages like "Item has been deleted", or "The item was saved successfully".
On the other hand, I have another web user control that represents the item in the form of an editable form (I made this a user control because this is used in two different pages). I want to embed an instance of the message box user control inside the editable form. I am writing this right after the @Control directive:
[Code]....
Instead of using @Register directives, I register the user controls in web.config and so far this has worked just fine.
With the above markup, the project compiles, but whenever I try to navigate to a page that contains this construct, I get an HttpParseException exception. Furthermore, Visual Studio states that the tack w7rc9:MessageBox doesn't represent a known control.
What am I doing wrong?
All I would like to be able to do is include one user control within another! Is this possible? I have spent the last hour searching the internet and it seems that I can't find a single thing.
In classic ASP it would be something like:
<!--#include file="EditProject.ascx"-->
I tried this but no luck!

I have a really odd behavior here: I created a little popup dialog in jQuery UI, and in my test HTML page, it works flawlessly. When I click on the button, the popup comes up, covers the background, and remains on screen until I click on one of the two buttons (OK or Cancel) provided.
So now I wanted to add this into my ASP.NET 3.5 app. I wanted to add it to a GridView inside a user controls (ASCX), which is on a page (ASPX) contained inside a master page.The jQuery 1.4.2 and jQuery UI 1.8.1 scripts are referenced on the master page:
<body>
<form id="XXXXXX" runat="server">
<Ajax:ScriptManager ID="masterScriptManager" runat="server" ScriptMode="Auto"> [code].....
Update: OK, one problem is solved - it appears that for whatever reason, the default MS Ajax stuff is adding some kind of an "observer" to my popup dialog and closes it right away after it shows up
So I changed the OnClientClick="showDialog();" to OnClientClick="showDialog(); return false;" and how that doesn't happen anymore - the dialog box pops up and stays there until I click on either of the two buttons (OK and Cancel).
On masterPage i have button btnTest, how hide button from masterPage on userControl.ascx
example:
btnSecondPage_click
{
btnTest.visible = false;
}
I have a web user control that actually takes a zipcode and based on that brings all the store locations. I am using this contol on couple of places. That works, but I have set of html pages and on one of them I have to setup the same functionality where user inputs zipcode and store locations are displayed to him/her.My question, Can I use that web user control as an applet on my html page without writing html markup and get post methods to achieve the same functionality?
View 1 RepliesIs there a way by which i can achieve functionality of page method inside a user control.
View 2 RepliesI have a user control with a textbox. I am loading it at runtime on parent page with code behind.After click of button on a parent page i need the text of that usercontrol's textbox.
I tried with following code but it does not work for me
myusercontrol us = new myusercontrol();
TextBox textbox = (TextBox)us.FindControl("txtusercontrol");
string str = textbox.Text.ToString();
How can I get all the textboxes inside a create user wizard control using getElementsByTagName().
Below is my JQuery code:
[Code]....
The above code isn't displaying hint text when the textbox retreives focus.
I think there is something wrong with this getElementsByTagName("asp:TextBox"); , I have also tried getElementsByTagName("TextBox"); , getElementsByTagName(":textbox"); and getElementsByTagName("input"); .
But no one of them gets the textboxes array.
Can anyone tell what will be the correct syntax for getting all the textboxes inside a create user wizard control using getElementsByTagName()?
I need to take information in ASP.net profile and add it as a parameter to html input control as follow:
html snippet is as follows:

code behind
{
ProfileCommon oProfile = Profile.GetProfile(HttpContext.Current.User.Identity.Name);
where
oProfile.mediaid is the oarameter required in <input> parameter doLoadChannel(mediaid)
I have tried a number of approaches to get a member of ASP.net proviles as a parameter of the function called by the control "input"
I have a user control with linkbuttons (used for paging) and a repeater inside an update panel. The paging works correctly, but is causing a full page postback every time I click through to the next page.
The update panel looks like this:
[code]....
So far, I have tried adding an async postback trigger for the user control, which does cause an async postback but does not update the rest of the text in the update panel. In otherwords, the async postback occurs and the next page shows up, but the original text in the repeater is there as well just below it.
I have also confirmed that I have IDS set on my linkbuttons, since that can trigger a full postback inside an update panel.
I have tried changing the update panel mode (Always, Conditional, ChildrenAsTriggers, etc.).
None of it makes a difference - the only thing that actually causes an async postback is to use the trigger, but then the rest of the content in the update panel is not updated, so I get duplicate content.
