I've got a web site that has a master page and that master page (mpMaster that has a user control ucControl1) which has a sub user control (ucControl2), this user control has a property which accepts a value. Now, I have a page that uses the master page and on this page I have another user control (ucPageControl), I need to find a way of setting the value in ucControl2 from ucPageControl. Is this possible at all?
i would like to ask about how can i open user control page when i click a button on parent page, also, can i call parent's method from user control page and then refresh parent page?
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?
I have a User Control with a multiple number of link buttons.
What I want to achieve is to change the Background colour of one of the link button control in the page load event of one of the pages. I am finding it difficult to access the link button in user control .
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?
I am trying to assign user control from another user control ..first time its binding control successfully but when we refresh the data its giving error
saying "Object reference is not set an instance".
how to refresh data from another user control ...
My senerio below :
1 Aspx page
2. User control
calling usercontrol databinding method from aspx page but once it get refreshed ,not allowed to bind it again..
I'm having trouble to access a Parent's property in User Control. I don't know how to access the parent. The Parent Page's name is Search.aspx. I saw the example below and tried it:
[Code]....
Than I could access the Parent's Property, but when I ran the website I got these errors:
1. The user control is not declared in the parent page 2. The user contol has a circular reference
I have a Master Page that has several User Controls on it. The MasterPage code behind does some work to calculate a value that needs to be used in all of the UserControls. From the UserControl code behind, how do I access the public property of the MasterPage that I have set?
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?
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?
I created user control. It exposes string[] public property (it may be List<string> or whatever). I want to support defining this property in aspx code, when declaring the instance of this usercontrol. Something like this:
I created a simple gridview user control with a custom property ProfileType which should load different records depending on the ProfileType value when attaching to a web page.
This is my web page:
[code]....
how I can expose user control custom property at its code-behind file.
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.
I have a checkboxlist control and a button control in a popup forum. The button is diabled initially. I want to enable the button as soon as the user checks or unchecks any of the items for the first time in the checkboxlist.
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!

i built a user control and i want to make one of its properties as a must, that's mean if you not supply this control when you create the control the project won't be compile, just like if you omit the runat="server" property.
I created one web user control with property named "ReadonlyField" with boolean datatype. I am able to use in my web pages and now i wanted to add a description to that property so that i dont need to explain each time to my team member what is that property's intention.
I got following snippet in c# but didnt find any equivalent in vb.net and also not sure whether it will work or not.
[Description("My Description")] public int MyIntProperty { get {..} set {..} }
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 created a user custom control, and what I would like to do is to pass it the text value from a label where I can carry out some other processing.
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.
