AJAX :: Developing A New Web Solution Where There Are Some Dynamic Control On The Page?
Feb 22, 2010I am new to AJAX. I am developing a new Web Solution where there are some dynamic control on the page.My requirement was to have a gridview this is in one update panel, on clicking on the edit gridrow, it will popup a DetailView which is in a update panel & a modal popup of the row & user can change it & submit it to the main page.Now i have used a Update panel for the detailed view so that i can call a update() on the Detailed View's update panel after binding it to the detailview.Now the detailed view updatepanel also has a drop down & a gridview, so selecting the dropdown it populates the gridview in the updatepanel.Again the dropdown is put in one updatepanel which even contains the gridview & the gridview is in another child updatepanel.The gridview has a checkbox in enabled =true stateNow the issue. When i do a checkbox checked & an autopost the event fires which updates the parent updatepanel & the event is lost in the process & i cannot modify the underlying dataobject.If any one can shed on somelight of where exactly i am going wrong, it would be of extremeI am pasting the code for the aspx file which contains most of the binding in declaraative mode.
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="DataPointManager.aspx.cs"

How To Handle Dynamic User Control Events In Aspx Page
Oct 28, 2010I have an aspx webpage in which an user control is added dynamically as follows:
UserControl testUsrControl = LoadControl("TestUsrControl") as UserControl;
testUsrControl.ID ="test";
Then I tried adding an event handler of user control inside aspx like below:
testUsrControl.Drpdatafield_SelectIndexChanged += new EventHandler(this.Drpdatafield_SelectIndexChanged);
But this line is giving error at **testUsrControl.Drpdatafield_SelectIndexChanged **. The error is "Drpdatafield_SelectIndexChanged" doesn't exist in UserControl.How can get the testUsrControl's events inside aspx page dynamically.

Web Forms :: Dynamic Controls Versus Building Dynamic Page
Jan 28, 2011Lets say I have a Web Application with a menu of products. When a user clicks a menu item, then create and display a dynamic set of controls in an Update Panel. I am currently doing this however the PostBack and recreation of controls is tedious and resource intensive.
Not sure about this but is it possible to build a webpage with controls on it, then display it in update panel or IFrame? Then on post back you wouldn't have to recreate everything all over again?

Web Forms :: Dynamic Control Creation In User Control?
Apr 19, 2010i developed a custom control (inherited from System.Web.UI.UserControl) which is used within a Gridview's TemplateField:
<sc:MyControl
runat="server"
id="my_ctrl"
AllowEditing="true"
NumberOfControls='<%# Eval("Count")%>' />
"Count" is an integer value from the GridView Datasource.
Based on this value i have to create some LinkButtons dynamically in my custom control (in Page_Init), which works very well when the value for NumberOfControls is hard-coded.
My problem is that the value of "Count" is not available (NumberOfControls = null) during Page_Init and therefore i can't decide how many controls there should be generated.
Is there any way to pass databinded values to custom controls so that they can be used earlier (as if the values were hard-coded)?
Page With Base Class With Dynamic Master Page Not Firing Events
May 3, 2010I am feeling that I have terribly wrong somewhere. I was working on a small asp.net app. I have some dynamic themes in the heme folder and have implemented a page base class to load the master page on the fly. The master is having the ContentPlaceHolder like: <asp:ContentPlaceHolder ID="cphBody" runat="server" />
Now I am adding pages that are derived from my base class and added the form elements. I know, Visual Studio has problem showing the page in the design mode. I have a dropdown box and wish to add the event of onselectedindexchange. But it is not working. the page is like this:
<%@ Page Language="C#" AutoEventWireup="true" Inherits="trigon.web.Pages.MIS.JobStatus" Title="Job Status" AspCompat="true" CodeBehind="JobStatus.aspx.cs" %>
<asp:Content ID="Content1" ContentPlaceHolderID="cphBody" runat="Server">
<div id="divError" runat="server" />
<asp:DropDownList runat="server" id="jobType" onselectedindexchange="On_jobTypeSelection_Change"></asp:DropDownList>
</asp:Content>
I have also tried adding the event on the code behind like:
protected void Page_Load(object sender, EventArgs e)
{
jobType.SelectedIndexChanged += new System.EventHandler(this.On_jobTypeSelection_Change);
if (!IsPostBack)
{
JobStatus_DA da = new JobStatus_DA();
jobType.DataSource = da.getJobTypes();
jobType.DataBind();
}
}
protected void On_jobTypeSelection_Change(Object sender, EventArgs e)
{
//do something here
}

How To Design Page To Allow For Dynamic Movement Of Elements On The Page
Mar 3, 2010I'm working on an ASP.NET page where I've got 10 entities. I'll call them Items. An Item can be displayed in one of two modes: Featured or Thumbnail. At any given time there is one Featured Item at the top of the page, and the rest are Thumbnails arranged in a 3x3 grid underneath the featured Item Each item is an ASP usercontrol that contains two divs: one div for Featured and one for Thumbnail -- when the item is Featured, the Thumbnail div is set as invisible and vice versa.

C# - Dynamic Controls In Databound Control?
Feb 25, 2010I have a control that inherits CompositeDataBoundControl. Based on the values of the bound data, I create som dynamic controls. In order to preserve state, I need to recreate the control tree on every request(from CreateChildControls):
[code]....
The problem is that on postback the PaymentMethod object is null, so I have no method of knowing what kind of control to recreate. That means that the control state is ruined. If I hardcode the type of payment control to make, it works as expected:
UserControl userCtrl = (UserControl)Page.LoadControl("~/WAF/View/VisitControls/Shop/CreditCardForm.ascx");
dataContainer.Controls.Add(userCtrl);
userCtrl.ID = "CreditCardForm";
how I can find out what payment method is used, so that I can create the correct control on postback?

Dynamic - How To Dynamically Construct A Control Name
Mar 2, 2011I am iterating through an array:
Dim dbConfig As New pbu_housingEntities
Dim possible() As String = {"FROD", "FRCD", "SOOD", "SOCD", "JROD", "JRCD", "SROD", "SRCD", "SR5OD", "SR5CD"}
For Each value As String In possible
Dim current_value = value
Dim exists = From p In dbConfig.Configs _
Where p.Description = current_value
Select p
If exists.Count.Equals(0) Then
Dim create As New Config
create.Description = current_value
dbConfig.Configs.AddObject(create)
dbConfig.SaveChanges()
Else
Dim update_query = (From p In dbConfig.Configs _
Where p.Description = current_value _
Select p)
update_query.First.Description = current_value
update_query.First.dateValue =
End If
Next
Towards the end of the array you can see update_query.First.dateValue =, I'd like to do something like this: update_query.First.dateValue = "txt" + current_value + ".Text" But I don't want it to return the literal txtcurrent_value.Text, but rather to return the text value of txtcurrent_value.Text. This is easy to do, if you know each control name - but in this case I'm iterating, otherwise I could do:
update_query.First.dateValue = txtNameofControl.Text
