Web Forms :: UserControl Event Firing From Parent?

Mar 4, 2011

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?

VS 2010 Dynamic UserControl - Postback Event Not Firing

Feb 8, 2012

I have a page where I add a dynamic user control in the Page_Load event based on criteria.

The control is a simple form with a save button. The problem is the _Click event never fires for the button. It will postback the main page the control is within, but not the code behind for the control...so I never get the button click even, and therefor can't execute the save code.

Tried it in the init, tried adding the control to a placeholder, tried a lot of various things but nothing seems to work.

Code:
If cb_business_profile.Items.Count = 0 Then
Dim u_pnl_content As UpdatePanel = Page.FindControl("u_pnl_content")
u_pnl_content.ContentTemplateContainer.Controls.Clear()

Dim business_profile_detail As Control = LoadControl("~/controls/business_profile_detail.ascx")

[Code] ....

Dynamically Displayed Usercontrol Not Firing Postback Event On Select?

Aug 20, 2010

i have a very strange issue with a user control we are dynamically loading on an asp.net web page(.net 2.0). the user control has 3 dropdowns, one of which has a selectedindexchanged event attached to it (which loads the third dropdown with a set of values).

the weird thing is, if there are currently any invalid fields (where field validators have been activated) in other parts of the form, when you go to select the drop down in question on the FIRST change it does nothing, but then when you change the index again it works perfectly! i dont understand how the event wont fire for the first change, but for every change thereafter.

However, if all these fields are filled in correctly above the usercontrol, it fires off the selectedindexchanged event correctly.

in regards to validation i have disabled ALL POSSIBLE validation in order to try and eliminate it as a culprit, so i dont understand how validation can be affecting the usercontrol.

I have a DetailsView control bound to an ObjectDataSource within a User Control (.ascx). It appears that the DetailsView.OnDataBound event is being fired on every page load or postback.

I do not see this behavior with a similiar DetailsView directly placed on an aspx page.

AsyncPostBack Firing On Child Textbox Trigger, But TextChanged Event Not Firing?

Jan 22, 2010

I'm sure I'm missing something extremely obvious here, but at this point I can't see it so I need the help.Anyway, I've got a repeater inside of an UpdatePanel. As of right now, I've stripped it down to this, just to try and isolate the problem:

[Code]....

Whether I add the handler during itemdatabound or I add the handler within the repeater itself, it doesn't seem to matter...the event itself doesn't fire. The AutoPostback itself seems to fire, but the event itself doesn't.

Web Forms :: Add Event Handler To User Control And Capture Event On Parent Page?

Apr 24, 2010

Using vb.net/asp.net 2005.

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.

Web Forms :: Firing Click Event On A User-control That Is Created From Another Event?

Mar 1, 2011

I have a gridview called gvResults. In the gvResults_RowEditing event I add a row below the one selected. In that new row, which spans all columns, I insert a user-control. There are two buttons and some textboxes in the user control.

My problem is that when I click one of the user-control buttons it never gets to the button event handler, I think because the user control is not recreated on the page postback. How can I have the user-control events fire before the parent page events fire?

I tried using an update panel, but I still get the parent posting back before the user-control events.

Forms Data Controls :: CheckBox Checked Changed Event Is Firing For Every Control Event?

May 8, 2010

I am facing one strange problem,I have a gridview in which the last two columns have checkboxes and on those checkboxes click event I am doing some database operations.I also have one checkbox that is outside the gridview which actually shows or hides some of the gidview columns.This was all working well but now I have shifted that grid to a user control because I have to use it in two pages.The problem now is,When the page first loads and I click the check box or any control in the page that is outside the grid then it works perfectly.But once I click any of the check box within grid view column then its behavior chages, now even if I click the checkbox that is outside the grid then also the checkbox_CheckedChanged event of the checkbox that is whithin gridview is fired.That checkbox event then behaves something like a page_load event that is called for every page load and for every event with in the page after it is called once.

Web Forms :: Dynamically Load UserControl, Access Properties In Parent Page Without Recreating In PostBack

Nov 15, 2010

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

UserControl - Accessing A Child Control In The Parent Page?

Nov 3, 2010

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.

Linkbutton Not Firing RowCommand Gridview UpdatePanel UserControl?

Jun 23, 2010

I have a problem with my Linkbutton which is not firing the RowCommand of my gridview.

Just for an Idea what I am doing is a follows:

1. WebForm

WebForm hosts UserControl_A.

2. UserControl_A = UpdatePanel + Panels + Gridview1 + CollapsiblePanelExtender

Updatepanel of UserControl_A consists of multiple Panels.

Each Panel consists of a Gridview1.

Upon each Panel expand UserControl_B is loaded.

3. UserControl_B = Details View & a couple of Linkbuttons in GridView2

Upon clicking the Linkbutton, unexpectedly it makes a refresh for the entire UserControl_A.

But it does not fire the RowCommand of its parent GridView2.

How To Call UserControl Javascript When Parent Page Submits To Server

Sep 8, 2010

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?
