Server Controls In User Control Are Null When User Control Serves As A Base User Control ?

Jun 4, 2010

I don't think I understand fully how ASP.NET does inheritance of controls.I have a user control, ucBase, which has an asp.net label in the ascx file. Code behind references the label and it works fine during run time if the control is not a parent for another user parent.

If I have another user control, ucChild, inheriting from ucBase, the label in ucBase's code is always null. ucChild has no controls in its ascx fileThe server controls (like the label) needs to be declared in the ascx file and not created programmatically.What needs to be done for ucBase to see its own controls when it's a parent user control?

How To Map A User Control Property To A Server Control Within It

Jun 2, 2010

I have a user control with a WebDateTimeEdit server control on it (essentially a TextBox). I'd like to be able to set some of the server control's properties by way of the user control's markup or programatically. for example I have this defined on my user control:

[code]....

this blows up because WebDateTimeEdit1 is null.

is there any way I can make this happen? also can do I do this

myControl2 .Font.Size = FontUnit.Point(8);

where the Font property is read only on the server control?

Web Forms :: Restoring User Control Property Values Upon Postback?

Jun 9, 2010

I'm constructing a User Control that will have one Property called "ContractIdx". Here's how I've constructed this Property:

public int ContractIdx
{
get
{
return Convert.ToInt32(this.Attributes["ContractIdx"]);
}
set
{
this.Attributes["ContractIdx"] = value.ToString();
}
}

I'm initially loading the User Control by passing a parameter to it and setting ContractIdx accordingly. That all works fine.

Upon Postback though I'm loading the User Control without any parameters and then setting its ID property to what it was before the Postback. My understanding was that if I did this then ViewState would properly restore everything. Yet apparently this is not the case with the "ContractIdx" attribute.

Where am I mistaken in my understanding? How should I change things to get this mechanism to work?

Web Forms :: Accessing User Control Property Value Across 2 Aspx Page?

Dec 20, 2010

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?

Forms Data Controls :: Passing Grid As A Property To User Control?

Aug 10, 2010

In my project, I need to create a user control to handle the sorting and pagination of all the grids in the application. The grid however will be different in different pages with different formatting.

I am able to do this by exposing a property from user control which takes gridview as the input.

then in page load, i bind this grid, and assign the sorting and paging event handlers to this gridview variable.

This way I am able to do the sorting and paging, but the problem is I have to bind the grid in all the post backs, and then in the sorting and paging events.

So when a user sorts, I have to bind the grid twice, once in page_load and then in sort event of user control.

I can store the first set of records in viewstate and bind that in page load, but is there any other way, so that i dont need to bind the grid in all post backs but only inside of not postback.

Web Forms :: Nest / Include A User Control Inside A User Control?

Apr 16, 2010

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!

Parser Error Message:

There can be only one 'control' directive.

Source Error:

Can Insert User Control With Inner-tag Content As Property Value

Apr 16, 2010

I have a control that I want to be able to mark areas as editable. When a user enters a username and password, they can then edit these editable areas.One of the area to edit is the main content of the page. Since I want them to be able to edit this on every page, I have put the editable control into the master page, wrapped around the ContentPlaceHolder of the master page.I found out how to allow the parser to allow <prefix:tag></prefix:tag> rather than just ending it with />, but I can't figure out how to get the text within the tags to be accessible through something like a Text property. A prime example of this behavior is the Label control, where you can put <asp:Label>Hello!</asp:Label> and access Hello! through the .Text property in the code.

I have a very simple user control with 5 radio buttons on it, and 3 properties (ID, RatingSetID, and Rating). On the initial load of the page they are on, the code acquires data and places the data into the 3 properties. However, when the submit button is clicked the page reloads and the 3 properties get reset to 0, they are in the !IsPostBack as well.
