C# - Where To Initialize The Usercontrol Properties Before Databinding?

Jan 10, 2011

How can I write the C# code (aspx) to initialize the user control with some default property values? I mean where/which event? I have a user control with a gridview that I bind on container page. On page load of the container page I bind the data. I tried writing the initialization code in initproperties but it didn't work. Please suggest where can I set the default values for my usercontrol?

Edited:As suggested by DOK.. I already have a property and I change width of one of the DIVs. Here is the code that is not working.

public int CollapsiblePanelWidth
{
set[code]....

this works only if I set the width on calling program. Otherwise the default value of style="width: 105px;" is not added.

Web Forms :: Using Properties With Databinding Syntax?

Feb 1, 2010

In an ascx control, it's possible to expose properties - let's assume the property name is a string property with a get accessor called DataField. If the ascx control contains a bindable templated control like a FormView and the FormView has a template that uses the two-way databinding syntax, why can't you provide a reference to the property in the call to the Bind method? I see that using the Bind method in a databinding expression causes the page parser to generate a method that is something like the following:

public System.Collections.Specialized.IOrderedDictionary @__ExtractValues__control8(System.Web.UI.Control @__container)

In which, I see the following line:

@__table["Some_Field"] = TextBox1.Text;

Now, this method (@__ExtractValues__control8) is an instance member on the same generated class that defines our DataField property, but when page parser goes to compile the control, I receive the following error:A call to Bind was not well formatted. Please refer to documentation for the correct parameters to Bind. I assume from this that the page parser requires a string literal to be provided, but I don't understand why.

DataBinding Not Working In UserControl?

Jul 30, 2010

[code]....

((Alert)Container.DataItem).AlertId.ToString() the value I get for SystemObjectRecordId in debug is null (but it still works when assigned to the text attribute of a literal).

5) The location of the User Control is default.aspx and the control is comments.ascx. The code files do not share a namespace.

6) I have tried manipulating the OnItemDataBound property of my repeater but since I have proven with the literal that data is getting bound using a declarative value I am not sure what else I could be doing inside the method logic of OnItemDataBound.

Once the end-user makes a comment in the UI, the SystemObjectRecordId value (which should have already been assigned when the page loaded - and we know it does in the case of the literal) should get passed to the codebehind of the custom usercontrol:

[code]....

No matter what I do, I always get zero for SystemObjectRecordId when passed via the custom user control I have on my default.aspx page.

ObjectDataSource Databinding: Getting Object Properties By Select Method Call - How To Access Value

Feb 22, 2010

I am using an ObjectDataSource control to call a MapInfo object. This object has two properties:

public IList Visits
public int TotalAvailable

The select method returns an IList but the TotalAvailable property is also populated. I have set the TypeName in the ObjectDataSource to the MapInfo object but because the Select method only returns the IList I don't have access to the TotalAvailable.

[code]....

Is there any way to access this value. I know it is being populated in the MapInfo object but all that gets returned from the Select method is the IList

Forms Data Controls :: Databinding Composite Control Properties Inside A Repeater?

Jul 14, 2010

I have a composite control inside a repeater. I am trying to set the controls public properties inline like so (this is a simplified example):

<uc1:Control runat="server" ID="id" Value='<%# Eval("value") %>'>

When I place the repeater inside a user control INSIDE ANOTHER user control and onto the page this works - the property is correctly set, if I inspect it inside the EnsureChildControls() method of the custom control the composite control's Value propertyis set to Eval("value") as intended.

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

UpdatePanel Dynamically Loaded Web UserControl Will Disappear After Clicking Any Button Inside The UserControl?

Mar 17, 2011

I've a ASP.Net page (Default.aspx) which will load UserControl (ucontrol.ascx) dynamically into an UpdatePanel. By using UpdatePanel, we believe we're able to prevent the entire page to be posted-back.

My problem is, within the UserControl, we have some form controls, such as inputs and buttons; after the UserControl is loaded, clicking on any button inside the UserControl will cause the UpdatePanel to be blanked. During the investigation, I found that, breakpoints within the Button1_Click() in the code-behind for the UserControl is never reached. Please reference to the code below, this references to [REFERENCE]1.

AJAX :: Nested UserControl With UserControl Disappears On Partial Postback

C# - Where Is The Component Initialize Method In 3.5

Jan 10, 2010

I want to create my own naming convention for page events rather than AutoEventWireUp but I couldn't find Component Initialize methods any where ? Should I override it ? But in which class it is defined ?

Edit :

For example : I don't want to use Page_Load but LoadThisPage naming. So It should be like

Load += new LoadThisPage(sender,e);

I was expecting a InitializeComponent method where I can initialize page,controls etc. events handlers...But it turned out to be Constructor function :

So what confused me is I thought there should have been a method like InitializeComponent which does things for me already created by Designer itself so I thought I could define my own event handler names within this method by overriding it in the say Default.aspx.cs .

Initialize The Controls In An InsertItemTemplate?

Mar 21, 2010

I have - for instance - an asp:FormView which supports Read, Insert, Update, Delete and is bound to a DataSource:

[code]....

If I am in Read-Mode or Edit-Mode the control is initialized with the property MyText of the current object which is bound to the FormView.

But when I go to Insert-Mode I do not have a "current object" (FormView1.DataItem is indeed null) and the controls are empty.

If I want to have my TextBox control initialized with a specific value how can I do that? In which event can I hook in to set default values to the controls in the InsertItemTemplate?

Especially I have in mind using an ObjectDataSource. I was expecting that the InsertItemTemplate is initialized with a business object which underlies my ObjectDataSource and which is created by the ASP.NET framework simply by using its default constructor when the InsertItemTemplate gets activated. In the default constructor I would init the class members to the default values I'd like to have in my controls of the InsertItemTemplate. But unfortunately that's not the case: No "default" object is created and bound to the FormView. So it seems I have to initialize all controls separately or to create the default object manually and bind it to the InsertItemTemplate of the FormView. But how and where can I do that?
