Web Forms :: Finding A Way To Access To MasterPage Property From User Control?

View 2 RepliesWeb Forms :: Restoring User Control Property Values Upon Postback?
Jun 9, 2010I'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?

View 1 RepliesWeb Forms :: Accessing User Control Property Value Across 2 Aspx Page?
Dec 20, 2010There 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, 2010In 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.

How To Map A User Control Property To A Server Control Within It
Jun 2, 2010I 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?
Can Insert User Control With Inner-tag Content As Property Value
Apr 16, 2010I 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.

Oct 28, 2010I have a very simple user control with 5 radio buttons on it, and 3 properties (ID, RatingSetID, and Rating).

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.

Set Web User Control Property To GridView Selected Row?
Feb 2, 2010I have a web user control (ascx) that exposes an "ID" property. What I want to do is set this property when the SelectedIndexChanged event fires in a gridview in the containing page. However, I can't seem to do it.... Here's my code:
protected void grdPhysicians_SelectedIndexChanged(object sender, EventArgs e)
{
physicians_certif1.mdID = grdPhysicians.SelectedDataKey.ToString();
mvData.SetActiveView(viewEdit);
panAdditional.Visible = true;
}
Physicians_certif1 is the user control. It seems the user control is loading before the SelectedIndexChanged event has a chance to set it's property.
How To Expose A Panel As A Property In User Control
Aug 20, 2010I have a user control with a panel on it:
CustomControl.ascx
<%@ Control Language="vb" CodeBehind="CustomControl.ascx.vb" %>
<asp:Panel ID="myPanel" runat="server"></asp:Panel>
I'd lke to expose that panel as a property that I can use at design time.
CustomControl.ascx.vb
<ParseChildren(True), PersistChildren(False)> _
Partial Public Class CustomControl
Inherits System.Web.UI.UserControl
#Region "Members and Properties"
<PersistenceMode(PersistenceMode.InnerProperty)> _
Public Property SomePanel() As Panel
Get
Return myPanel
End Get
Set(ByVal value As Panel)
myPanel= value
End Set
End Property
#End Region
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Response.Write(myPanel.HasControls.ToString())
End Sub
End Class
And then bring the control onto a page like so:
<ucl:CustomControl runat="server">
<SomePanel>
<asp:Label ID="lblText" AssociatedControlID="txtBox" runat="server"></asp:Label>
<asp:TextBox id="txtBox" runat="server"></asp:TextBox>
</SomePanel>
</ucl:CustomControl>
When I run the page, HasControls is true but nothing is rendered. What am I doing wrong?
C# - Can't Initialize A User Control Property Using Eval
Feb 23, 2010I designed a user control. It contains a public property "CurrentValue". When I try to initialize the property using an Eval expression, a null value is assigned.
// In below code, label assignment is OK, RatingNull user control assignment get null
<asp:TemplateField>
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Eval("Difficulty") %>'
<uc1:RatingNull ID="RatingNull1" runat="server" CurrentValue='<%# Eval("Difficulty") %>' />
</ItemTemplate>
If I directly assigned a value (ie, CurrentValue="5"), user control works fine.
public partial class RatingNull : System.Web.UI.UserControl
{
private string _CurrentValue;
public string CurrentValue
{
get { return _CurrentValue; }
set { _CurrentValue = value; }
}

'DataBind' A Single Property Of A User Control?
Dec 3, 2010Before I get to the question, let me give a bit of background. I'm trying to develop a custom caching mechanism that I can apply to custom built user controls. (Please be aware that I know that there are some built in caching mechanism in .NET) Depending on certain flags set declaratively in the mark-up the control should load a cached version of its previously rendered content or execute normally (and if certain flags are set it should generate a cache of its content for next time it loads). I would like to be able to pass certain flags declaratively in the mark-up and being able to check their value at Page Init and, depending on the flag value, determine whether the control should load a cached version or not.
<uc:MyUC ID="N1" runat="server"
CacheProp='<%# SomeEnum.A | SomeEnum.B |SomeEnum.C %>'
PropA='<%# this.SomePropA %>'
PropB='<%# (this.SomePropB %>'
PropC='<%# this.SomePropC %>'
/>
The problem that I'm facing is that as far as I'm aware I can only get the value of the properties declaratively assigned in the mark-up if I called the DataBind(). However I'm faced with two problems: Firstly calling this.DataBind() from within MyUC will trigger the binding of all its child controls which would defeat the purpose of the cache; also all user controls have been built so that they will not call DataBind() before the LoadComplete event has fired, so to make sure that the parent controls they live in has done its initialisation and has computed the properties that are declaratively passed to the child user control (ie PropA, PropB, PropC).And now the question: is there a way to bind the CacheProp property so to retrieve its value without data binding all other properties and without triggering the data binding of all its child controls?
