I am loading dynamic ascx controls into a placeholder using:
Control control = LoadControl([controlpath]);
PlaceHolder1.Controls.Add(control);
I need to pass the data to its public properties.
Passing dynamic value to Detail view of grid through object selecting parameter

View 3 RepliesI have a user control (ascx) which contains a control (hidden field). In the page_load event of ascx, i have the below code:
HyperLink.Attributes.Add("onclick", "JavaScript:return AccessControl('" + hdnField.UniqueID + "');");
Note: The hidden field resides in .ascx file.
I want to access this hidden field at runtime and i have the below javascript function in aspx page that loads the usercontrol.
function AccessControl(hdnFieldId)
{
var ctrl = document.getElementById(hdnFieldId);
alert(ctrl);
I am getting 'null' value in the alert. I tried using 'ClientID' and 'this' instead of 'UniqueId'. I am wondering why this is not working. I am using .net 2.0.
I'm using a user control which uses a dropdown. I call a parameterized stored proc to to populate it. I don't know how to pass parameter '_ReportName' from main aspx file to ascx file.
HTML Code:
<asp:DropDownList ID="dropSortOptions" Width="200px" CssClass="Dropdown" runat="server"
DataSourceID="sqlDataSource" DataTextField="Option_Desc" DataValueField="Option_ID"
AutoPostBack="True">
</asp:DropDownList>
<asp:SqlDataSource ID="sqlDataSource" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionStringName %>"
SelectCommand="sp_SortOptions" SelectCommandType="StoredProcedure">
<SelectParameters>
<asp:ProfileParameter Name="ReportName" PropertyName="_ReportName" />
</SelectParameters>
</asp:SqlDataSource>
if Panel have any aspnet control,panel not popups.otherwise working.whats wrong here ? is it impossible ?

I am loading a series of controls in the Page_Load event. However, I have to recreate those controls each page load, which means storing their data elsewhere. This is cumbersome.
protected void Page_Load(object sender, EventArgs e)
{
MyControl control = (MyControl)LoadControl(...);
control.Initialize(GlobalClass.controlData);
//^gives the control the data it had previously.
//Or use ViewState["controlData"] if serializable.
Controls.Add(control);
}
I feel like I should be using if (!IsPostBack) {}, but I don't know how, or why. In contrast, if I place the controls into the markup, then the controls seem to stay persistent. For example, a button in mark-up will remember any changes to its Text property (I think?).
<asp:Button ID="buttonText" runat="server"
Text="Text Segment" onclick="buttonText_Click" />
How do I maintain some sort of persistence with dynamically added controls, like controls added via mark-up? This would save me much work and frustration.
(I've coded for a small eternity, but the more I do ASP.NET, the more confused I become. Which is exactly the opposite of what how I understood learning to work :-P.)
I have been playing around with loading user controls in a CMS style where I can change the position and order. I have come up with this...
[Code]....
It all works fairly well - but I have alot of propertys in my user control code behinds where I could inject values into the usercontrol from my base class.
I like the way I can position usercontrols from the DB, I even added a time and date section where they could be switched on and off per day or time.
If I make every user control access the DAL for the data, it means i will have one select per user control, which means including my bassclass I could have upto 15 selects (visits tot he DB) to make the front page. Though this does not seem to make a performance problem, I was wondering if there was a better way of doing this.
so I have this custom user control, just some data inside divs with a fancy css.
So inside my page I need to add it multiple times, and I do so in code behind within loop.
Now, this code doesn't work
[Code]....
and of course it works fine now. My questions would be - why? can I do it without pecifying file name and just creating control the normal way like in first example?:S
In the process of migrating an old VS2003 web app to VS2008, I'm running into this issue and haven't been able to find a resolution. Sample code: "Default.aspx" has a PlaceHolder(ToolHeader). In the Page_Load(), we dynamically load a user control passing in the virtual path to a helper method [public Control ParseUserControl(string virtualPath)]. This reads the content from the physical path, returns
a Control from ParseControl() method. I immediately get the following error when I open the default.aspx page in browser.
Parser Error
Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately. Parser Error Message: Could not load type 'DynamicUC.UcControl'.
Source Error:
Line 1: <%@ Control AutoEventWireup="true" CodeBehind="UcControl.ascx.cs" Inherits="DynamicUC.UcControl" %>
Can't figure out why it can't load the type. Namespaces are looking right. I try removing the Inherits="DynamicUC.UcControl" attribute from the "ucControl.ascx", it loads the page fine. Also, this control is a simple one and has no code behind. There are others with actual code behind. They won't work if I remove the Inherits attribute.

I have a loop which creates for each item ID a Dynamic created checkboxlist control
how do I create a dynamic validation control on a dynamic checkboxlist?
From an ascx page, I click a link that opens a popup aspx page(child). That aspx page has a gridview with hyperklinks. When I click on one of the hyperlinks of my gridview, I want to pass the value in that cell to a textbox located on my ascx page(parent). I try using javascript , but I can't get it to work. here is my javascript code and the gridview code:
<script language="javascript" type="text/javascript">
function post_value(str) {
window.opener.document.getElementById('textbox1').value = str;
self.close();
}
</script>

I have an issue with gridview and ascx's inside. Into the item template I'm dynamically loading ascx files depending on the row hiddenfield value. Ascx control is then "opened" in panel with modalpopup extender. The issue is ascx control with ceratin programming logic behind does not postback in this scenario.
Is there any workaround here?

I am using query string to pass values from page 1(log in page) to page 2 and then page 3. I have an .ascx file also, so how can I import the user name from Page1(login.aspx) to menu.ascx file. So that when I click the menu Home the value of the variable remains at the website. I am not aware of session handling thats why I am using this method to pass the valus among the various pages in website.
View 4 RepliesI have a user control with a listview and a pager. The pager doesn't seem to page, it just reloads the same page. I have 4 dropdowns on the page that a user select from, they then click a button to fill the listview with data. I use a method in a class to pull the data like so
this.ListView1.DataSource = DB.GetResults(
CategoryID,
CountyID,
SubCategory1,
SubCategory2);
this.ListView1.DataBind();
Do I need to rebind the listview somewhere?
I'm developing an ASP.NET application with C# and Ajax.I have a page that holds user controls loaded dynamically. I need to pass some data (integer values and some strings) to the user control that has been loaded dynamically.Now I use Session to pass these values, but I think I can use another way; something like VIEWSTATE or hidden input.What do you recommend me?The fact that I load the controls dynamically is important because controls are loaded on every postback, and I can't store any value on controls.

ddlAnswer.SelectedIndexChanged += new EventHandler(ddlAnswer_SelectedIndexChanged);
Please note that drop down list is dynamic, and in selectedIndexChanged, I would like to pass the "QuestionID" to that selectedindexchanged to work on my logic. Is there a way to pass it to that method as command argument or something?

I have to build a few ascx partial views in my MVC applications to encapsulate re-usable functionalities as well as archive SOR and SOC. However, I encountered challenge how to encapsulate the business logic that drives MVC ascx views.In webforms, the code behind of an ASCX control can handle a button click event and browser still shows the same page with only one postback. How can I archive the same thing in MVC? When ~/Address/Edit/2 includes an ascx partial view with a button on it that calls another MVC action - let's say ~/ShareController/CommonAction - what is the best way for the CmmonAction to return to the very same view that includes the ascx file?Perhaps I am missing a common pattern in MVC web development?
