Is it possible to do this? Or do I need to make a server control for this functionality? I have it being able to be set in the Page_Init, but I'd like to make it as similar to actual controls as possible. Also, if it is possible to access via the Events section under Properties, that would be good and 2. I am trying to register the web user control as an AsyncPostbackTrigger for another UpdatePanel. With the previous question in mind, is it also possible to set this via the GUI, or does this need to be set programmatically as well?
I have a page books.aspx that has a control named authors.ascx.
Inside the authors control there is a "select" button I want to add some kind of listener or event handler (not sure of the correct terminology) so on the parent page (books.aspx) I can respond to the "select" button being clicked.
I have to pass the authorID from the user control to the parent page.
In my authors.ascx control I just created this event:
[Code]....
Now I need to write the function for SelectAuthorBtnClick and I think add some kind of listener in the parent page to listen and handle the event.
I have a need to improve the asthetics of the standard buttons .net churns out. I am fully aware of how to do this using css but I can only really style the button if I add a span element inside the button. Luckily the link button allows this so I have got the following which for usability i have put inside a user control.
I have exposed elements so that I can set values from within my aspx.cs page, these are text, command name, command argument, ccc class etc.
As it is a generic control, I have added OnCommand='Button_Click" which fires the event in the control itself. The Button_Click event calls a method ButtonControls passing associated command name and arguments across. ButtonControls uses the name to call the appropriate function.
As these are all very generic buttons, so far so good, but I have a need to trigger button events that may not be generic i.e on a control I have buttons that do something very specific to that control. I also have a requirement to call functions which relate to specific controls on the aspx page. I have created a user control which encapsulates the link button control.
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 LinkButton within a User Control and it has handled with:
Private Sub LoginLinkLinkButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles LoginLinkLinkButton.Click Response.Redirect("/", True) End Sub
On certain ASPX pages I would like to handle the click from the page's code behind, opposed to within the user control. How do I override the handle within the control from the parent's code behind page?
Update:
Based on the answer, I have the following no added to the User Control:
[code]....
The problem is determining the correct syntax for the if line because the above is invalid.
A little confused on something. I have a User Control in a master page. In the User Control there are image buttons. when I try to wire any click event even to say update a label in the User Control itself, nothing gets updated.
It is as if the postback is not handled at all.
What I want to do is click the image button in the User Control and then change a value in the master page. This could happen a few ways but for example it could update a public property or a control itself like a textbox or label.
I have a user control with two drop down, on selection change of first dropdown second dropdown should get populated. Now when I place this user control in a aspx file, I need to access the second dropdown value on change of send dropdown .
eg: in ascx file
Department drop down and employee dropdown. on change of department dropdown, employee dropdown should populate. (which is working fine for me)
in aspx.cs file
on change of employee dropdown, I need to get the employee id and so some other operation. (I am struggling here)
Is there any way where I can fire usercontrol event from aspx.cs file?
i would like to ask about how can i open user control page when i click a button on parent page, also, can i call parent's method from user control page and then refresh parent page?
I've run into a problem with one of my web sites and I am having trouble figuring out the problem and a good solution. This is my scenario: I have a user control that displays a slideshow with images and some text that changes every fifteen seconds. To do this, I have an update panel that contains a timer control with an interval of 15000. It calls a method called slideshowTimer_Tick in the codebehind. The web page that contains this user control is a relatively simple page; no update panels or timers, just divs.
The problem I have is that if I have two of these user controls on the page, the tick event only fires for the first control. It never fires for the second control, although the control is full initialized otherwise.
I have parent form in which i have two buttons. button1 and button2. By clicking on button1 a model popup widow shows. In popup window i have a button like button3 what i need that by cliking on button3 on popup page i want to fire button2 event on parent page and close popup page.
I have a datalist that loops thru cart items. Within the datalist template I call a user control that has a small form that gets repeated for each item. When this control is called outside of the datalist, the form submits fine, but when called within the datalist the button has no event action. I've tried adding an event handler to ItemDataBound of the datalist, but still no event action. How can I get my form to submit?
I am fairly new to the asp.net and experimenting with it to learn the page life cycle. Here is a problem that I have been unable to resolve for past few days.I have a hosting page (.aspx). Then I have two user controls (.ascx). The page has a place holder control in which it loads the user controls one at a time based on the application flow. First user control is loaded on application start up. It has a "continue" button. Continue button click loads the Second user control that has two buttons - "Back" and "Submit". Obviously the "Back" button should load the first user control again and Submit button should submit the form data.

Obviously the "Back" button should load the first user control again and Submit button should submit the form data. Pretty simple.
The problem is that the command button event handler that I have on the second user control is not firing the first time. (I have one event handler for both buttons). The load event of the user control fires but then it ignores the button click. If I click it again, then it fires. I re-load the controls on the page in every page_load. Here is some relevent code:
AddPlayer.aspx:
[Code]....
The page_Load fires every time but "CommandBtn_Click" doesn't fire after the first click. I have to do it click it again. It doesn't matter which order I click the buttons.
I have created one user control for changing the theme of the page where i have several buttons and on click of each button i am applying the theme of clicked buttons color and for that i have created several css files like red.css, blue.css , green.css etc.
now i want to apply this theme to the page but i am not able to do that from the user control as because i am not getting the stylesheet property in the page and thus i am not able to work further.
can anyone tell me how can i apply the theming from user control to the page its being called.?
Basically, I have a user control with a set of input controls such as textboxes and radio buttons. It also has a button along with these controls. What I want is that when the user clicks this particular button, the data entered in the input fields must get updated into a grid in the parent page.
how to call a function of user control from the parent page?
I have a user control inside of default.aspx page, And I have a function in the code behind of user control. I need to call that function from a code behind of default.aspx
I've created a User Control (.ascx), which has a dropdown. When an item is selected, it uses some model classes to pull back a set of data which it then dynamically displays as a list of checkboxes in a panel control.
When I add one to the page, it works very well indeed.
However, when I add another I get this behaviour:
1. Select an item from the first dropdown, the checkboxes appear underneath ok.
2. Select an item from the second dropdown, the new lot of checkboxes appear ok, but the first lot disappear.
It's rather frustrating, they both have different IDs on the page, so they shouldn't interfere with each other should they? There is some Javascript that I've added but I use the Panel.ClientControlID to separate these out (I've already thought of that one).
I have a user control that has several data components
What I want to do is populate the data components based on the parent's page title where the user control is called.
The parent page title is the most logical unique name to each page and so that would be the name that I want to import
as the default value for the data components select parameter. Each page name is stored in my sql data table [Towns] as TownsName.
The general idea is that the control will populate with the towns data based on the page title of the parent page.
<SelectParameters> <asp:ControlParameter ControlID="DetailsView3" DefaultValue="PAGE TITLE NAME GOES HERE" Name="TownsName" PropertyName="SelectedValue" Type="String" /> </SelectParameters>
I am not sure how to code this correctly, but I am sure it would have to be called in the page load statement.
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load SetAttr(DetailsView3.DefaultValue = Parent.Page.Title())<-------THIS OFCOURSE DOES NOT WORK End Sub
I have spent a couple of days trying to work this one out and have failed to find a workable solution..
I have a user control with contact form and validators, when I add it (user control) to my parent page I get a strange behavior of all buttons within the parent page, Any button I press on the parent page fires the validators of the user control. How can I vallidate the form on my user control only when I press a specific button?
i have a page with 2 Textboxes. in that page i use userControl with 2 textbox and a Save button now case is when i click on Save Button...i want to validate my controls. Both of page and both of usercontrol. in usercontrol is done by customvalidator... because of some specific conditions. now same time ... the controls of page should be validated for requred fieldvalitors, the issue is.... same type of usercontrol i have and which are on page same time. so i am not able to fire validation controls for parent page.
