View 2 RepliesI wanted to know if we can pass values from Parent page (in this case from Default.aspx page) to the user control and maintain those values on subsequent "Add/Load" of user control.
So in short, if I click the "Add" button it loads my "webusercontrol" and also I am able to pass my default.aspx dropdownlist value to this dynamically loaded user control and assign it to a "Label or Textbox" which resides in my "webusercontrol", now the problem is that the value doesn't persists! What I meant is , when I click "Add" button again the "webusercontrol" gets loaded again perfectly but now all my "Label's" in webusercontrol has the new selected value from the default.aspx dropdownlist.
So say for instance I have a Dropdownlist in Default.aspx page with Values "Apple, BlackBerry, Nokia" and initial value to be passed is "Apple", I click the "Add" button, now my "Label" inside webusercontrol has the value "Apple", perfect! Next when I click "Add" button again and select a different value to be passed this time say "BlackBerry" now I have 2 webusercontrol loaded on the page, so that means I have 2 "Labels" with different ID's, but now my first Label initially had the value "Apple" because that's what I had passed and now when I passed the value "Blackberry" both the labels of my webusercontrol has the value "BlackBerry" instead of one being "Apple" and another "BlackBerry"
Is there a way to resolve this issue? may be Dictionary List?

View 3 RepliesI have a user control that i add at run time like:
PlaceHolder1.Controls.Add(mycontrol) because i want to make it appear when i click Checkbox control
Checkbox_changed IF CheckBox2.Checked THEN
PlaceHolder1.Visible = TRUE
The problem is that i want to get values from the page and use them within User Control page
I have a simple user control which toggles between the visibility of a few images depending on the UserId. When the page is loaded for the first time, the userID is being assigned correctly (I'm debugging). However, there are two other buttons on the page for filtering the type of users, they are perform their functionality via Ajax (not the toolkit, but the normal javascript ajax) When one of these buttons are clicked, the user control cant get the userid, it always comes up as Zero. Oh, btw, the usercontrol is in a DataRepeater, so it occurs for each of the user.. all the time.. or thats the Idea. I have several other pages like this, (none of them have ajax) and the user control has no problems whatsoever.
My User control code:
[Code]....
And the Data Repeater is something like this:
[Code]....
Here, Immediately after the userControl <ucAB:....> line, I am printing the userid just to see if its valid (by <%# Eval("UserId") %> and the user id's are valid too. I dont understand why the User Control cant pick it up on ajax postback?
I'd made a WebUserControl called Matrix, this UC inherits from the Gridview control. The Matrix User Control has 9 properties, which of 3 properties are the DataSources DataTables). The 3 DataSources are the RowSource, ColumnSource and DataSource. Together they form an gridview with labels (name of column) at the header of each column, a abel (name of row) at each first cell of a row and rest of the cells on each row are checkboxes. This forms a kind of Matrix, that's why I named it so.
I drag the Matrix User Control on a new .aspx page, for example Index.aspx. In the Page_Load event I set the 3 DataSources and DataBind the Matrix Control. Then the Matrix is build up correctly.The user can now edit the gridview by checking or unchecking the checkboxes. I also have a 'Save' button on the page which has an ID 'cmdSave' to save the changes.What I wanna do is: I want to have a Method within the User Control which gives me back a list of checkboxes which are checked. But when the OnClick event of the cmdSave button is fired, the data of the User Control is null/empty. And how do I get the changedHow can I fix this and build a method which gives me a list of checked checkboxes?If not everything is explained clearcly,

I am developing an application in which I have to use a User Control.I have created a user control in which I am using
- A Label (whose text will be dynamic)
- 3 Textboxes (whose values will be also dynamic).
So far everything is working fine.Now I used this user control in a aspx page and at the page_load i have to loop thru all the instance of this user control and assign values to them and here the problem begins.The values are not being assigned to the controls.
Here is the code which i have written to loop thru User Control instances and assign values to them.

I have a page that contains a few user controls which all use an id in a querystring. I want to change this so that the page can send the id to the user control and can call a function on the user control.
Also is it possible for the user control to get the id from the page or a control on the page as its parent?
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?
(using c# and .NET 2008):
I have a main web page and added a user control inside it. The user control has some textboxes. The problem I have is when I populate the textboxes with the data that is in the DB, they do not show the values. The strange thing is If I change the property of textboxes ReadOnly to TRUE, they show the values. The problem is that I need them to be ReadOnly=FALSE.
i have two user controls uc1 and uc2. uc1 as button and uc2 has label, so default.aspx contain both uc1 and uc2, How can i change value of label by clicking on button??? remember both are in the different user control.
View 1 RepliesI have a web form and I have a user control on it. This user control contains a panel with some user properties that are to be stored in a database. So far nothing fancy. The user control itself contains a panel and is working fine (all code to retrieve and store the values is working).
I used the default settings of creating a user control and one of them was AutoEventWireup=true. This works fine because I also have some dropdown boxes (and other fields) that need to be filled with values from the database and that happens in the Page_load event.
The panel specifies the 'DefaultButton' which calls a method when clicked to save the values after the user has changed them.
On this click the code of the method is called, I confirmed that, but I found out that the values of my controls on the user control (for example the Textbox control) are empty. As a non-ASP.NET developer I couldn't figure out why. So I changed some settings like AutoEventWireup to false.
Off course this resulted in my dropdown boxes no longer to be initially filled, but my surprise was big to find out my controls actually contained the values the user typed in.
Logically I need both the values and the dropdowns filled, but for now it seems one or the other.
How you can send values from master page to user control in code behind (not through URL)?
View 3 RepliesI have a user control on a web page . I want to use the values of the web page on my web user control.How can i do this
View 2 RepliesI 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.
View 2 RepliesI haven't used these in awhile. I was just wondering is it possible to pass values or parameters to a user control from the aspx page. Say you register a control and then use it using something like
<uc1:SampleUserControl id="SampleUserControl1" runat="server"></uc1:SampleUserControl>
style syntax. Can you pass parameters in there?
I have a user control I am adding dynamically. It has a link button and a text area on it. The containing div is hidden via style sheet (client side), and I use some jquery to pop it up in a modal. It is getting added in the init and the button click event is firing on the server. BUT the textareas value is not being set. On further inspection the field value is not even being sent in the form POST data. why the value is not being sent. The rest of the form values are being sent with no problems.
View 1 RepliesI am trying to build a web user control and set some default values for its properties in the code-behind like this:
[DefaultValue(typeof(int), "50")]
public int Height { get; set; }
[DefaultValue(typeof(string), "string.Empty")]
public string FamilyName { get; set; }
[DefaultValue(typeof(Color), "Orange")]
public System.Drawing.Color ForeColor { get; set; }
When I add the user control to the page and call it without any properties:
<uc1:Usercontrol ID="uc" runat="server" />
the default values are not set and every property is 0 or null.
I have built a user control that has a public property string[] foo.
Is it possible to assign this in the actual markup?
The type of project is ASP.NET webforms / web application.
Ive tried the following syntax, but it doesnt work: (It compiles but the value is never assigned).
<abc:MyControl runat="server" foo='<%# new string[]{"Hello"} %>' />
I have a user control which has some properties configured on it. I need to access (actually, only read) the values of those properties on the client. I have done it like this.
Code behind:
[Code]....
ASPX:
[Code]....
That works but, at the back of my mind, I'm sure I've seen a neater way of doing it, although I suspect that may have been on an Extender not a User Control. Pointers on that welcome.
Also, related to that, the User Control itself has an Id which becomes part of the name of all visual objects included within it. However, the User Control is not a DOM element in its own right (because it has no visible rendering) which [I think] means that I have to attach properties to one of the visible elements within it, and not to the control itself?
I have a ObjectDataSource and a ListView referencing it.
I have created a Templated User Control (see:
http://msdn.microsoft.com/en-us/library/36574bf6.aspx) and placed it in the ListView's InsertItemTemplate
It has one template <ContentTemplate>. Inside that template, I've defined a couple of server controls with their properties = '<%# Bind("colName") #>'.
See below:

suppose i've created my own user control, and it has a textbox and a property for the textbox so that if i use the user control from within the aspx file, i can give the property a value. for example:
[Code]....
is it possible to also set the property to be seen via the desing mode , just as it works for other (built in) controls? maybe a different method to implement the same scenario?
if you still didn't understand what i mean : after setting the value of DefaultNum1 via the code i've written here, i expect the textbox associated with this property to be updated as well to '1' via the design mode (and split mode). of course it won't work using the current method, since VS cannot guess what is going on with the property and understand that all of its purpose is to assign an initialization value for the textbox.
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'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?
