Web Forms :: Passing Values From Parent Page To User Control And Maintaining The Values Added

Mar 18, 2011

I 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?

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.

<uc1:SampleUserControl id="SampleUserControl1" runat="server"></uc1:SampleUserControl>

style syntax. Can you pass parameters in there?

User Control Is Not Posting Its Form Values

Mar 14, 2011

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.

Web Forms :: Can't Assign Values To Variable In User Control

Jun 17, 2010

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:


And the Data Repeater is something like this:


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?

C# - Setting Property Default Values For A Web User Control?

Apr 15, 2010

I 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.

Forms Data Controls :: Get The Values In The User Control?

Feb 4, 2010

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,

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
return Convert.ToInt32(this.Attributes["ContractIdx"]);
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 :: User Control Does Not Let Me Assign Values Into Text Boxes?

Dec 14, 2010

(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.
