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.

Web Forms :: Accessing Methods In A Parent Masterpage From Child?

Jul 26, 2010

I have a main MasterPage that, as intended, forms the entire layout of my site. It has a bunch of methods common to all pages that use the mastertype, such as EnsureLoggedIn and such.

I want to move on to using nested masterpages to open up better layout options in some of the pages, but I am running into an issue. I get the layout of the nested masterpages fine, but I cannot access any methods in the parent masterpage.

I know my explanation seems a little sparse; I'm not exactly sure how to word what I'm looking for, heh. But here's a short example:

Web Forms :: User Control Accessing The Parent Page Load Event?

Mar 4, 2010

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.

'*******************************************************************

The user control is being referenced from the web.config file ** Works find! **

EDIT.ASPX Page **-- WORKS FINE!** [Code]....

Accessing Tablerow Child Control By Type

Aug 11, 2010

I'm iterating through a collection of asp:tablerows to be able to get or set the text in a textbox that is nested in the third cell of the row; I'm doing this by type rather than by ID because the cell ID's in that column aren't totally consistent--thus I can't really call FindControl() to achieve this. I've resorted to casting the third control in the TableRow to a TableCell and then Casting the first control in that cell to a TextBox. Not quite correct, as I'm getting an index out of range exception thrown. The problem mainly lies in the Controls.Count() property of the third cell, which comes to zero. Not sure if there's a better way to access the textbox---should I resort to FindControl()?

foreach (TableRow row in tblProviders.Rows) {
string value = ((TextBox)((TableCell)row.Controls(2)).Controls(0)).Text;
...
}

My searches here only yielded use of FindControl(), so that may be the only way...

Web Forms :: Passing Value From Child Page To Parent Page?

Jan 11, 2011

In the parent page i'm displaying all the user details and one of the detail is the list of accessible clients in a list box. the clients can be removed or added using the add or remove images next to the list box.

Clicking on the Add image will show you the list of available clients in a new page(child) and also showing currently available clients to the user with checked status.

Let me explain how the available clients for the user is displayed in the child page. In the parent page load on the 'Add' image 'OnClientClick' i'm passing the ClientId of a hidden field in which all the selected clients for a user is stored.

The problem i'm facing here is when i altered the selected clients in the child page and clicking on the OK button will change the value of the listbox in parent page using the clientID of the listbox which i'm passing, but if i once again click the 'Add' button it shows the original values which is stored at the time of parent page load. The problem is i'm not doing any postback here so that the original values registered during 'OnClientClick'of 'Add' button is not altered.
