Currently a page loads usercontrol via
[Code]....
and Test.ascx has the following event
[Code]....
How can I add this part OnEvalCommand="Eval_Command" to the control at runtime. I am familiar with setting properties but not events.
I am creating a web application that displays URL to users in a GridView. The application has a code behind that will be doing the processing before it can return me a URL. This is done in a loop. So it looks something like :
[Code]....
What I wanted is to make the Gridview always update the rows everytime an item in the loop is done instead of waiting for the loop to finish.
For now, the application will only display the whole table until the code/loop finishes. I'm very much aware that this will happen because the web page is static in the first place. Does anybody know how to do this?
I have tried of using iframes(I thought of reloading the frame so the whole page wont reload again and a new GridView table would appear because of the code in Page_Load event because I tried placing the data in a separate static class and the GridView.aspx page will just retrieve the values upon every reload)
and I'm not sure how to implement AJAX/Javascript with this. Is Animation involved in this kind of situations?
I'm trying to add some user controls on a page. Thats easy, I just do it like this.
UserControl block = (categoryblock) LoadControl("categoryblock.ascx");
Panel1.Controls.Add(block);
But i want to access the label controls and more that are inside the categoryblock.ascx. How would i do that? I cant do it like this,
block.l_itemName.text = "blabla";
I managed to user FindControl("l_itemName") but i would rather like to have the intellisense.
I am showing data from different databases in a web part. Would it be possible to dynamically add and remove that data including the layout that that <DIV> has and would I go about in doing this?
View 3 RepliesIm using VS 2008 and have created a Visual C# ASP.Net Web Application and have a Table on the Page (Created at Design Time).
Im Trying to add rows at runtime when the user presses a button but it creates one row then none after.

to duplicate an already existing <div> with its existing controls multiple times on one form. I have a situation where I have a group of controls contained in one <div>, but the user might need to add more information in the same format so I would like to just have them click a button to add another component and the same set of controls will be duplicated below it.
View 6 RepliesIn my Page_Load() event, I'm calling a Sub (in a module UserMenu.vb) that reads an XML file which has the user menu entries. The final menu should be an <ul> with several <li>, some of them with anidated <ul> within. As I understand, I may use a asp:Panel in my page to position a container for this elements I read and in this sub I try to add them using new BulletedList and new ListElement BList.Items.Add(LItem)), but when I get to Panel.Controls.Add(BList) it throws an error that says BList should be inserted in a Form. Why? Aren't they just <ul> and <li>? What other alternative I have to create <ul> and <li> in a specific part of my page?
View 3 RepliesI need to have a siteMapeNode for a menu control to only show up during development.
The following node would be in the web.sitemap file.

I can either put this node in my web.sitemap file and remove it in release builds.
Or Add the node in debug builds.
Probably done in PreInit or Page_load events.
I'd like to add a control A (that exists on a page) to a Footer user control's panel. If I create the control A dynamically and add it, I don't have issues. But I would like to avoid adding this dynamically.So, I defined control A in the aspx page and in the code behind, I got reference to the footer's panel and did a Controls.Add() It works fine, but postbacks from this control has strange behavior (could be due to viewstate?) as it doesn't execute some code that is on the page with a !IsPostback condition

View 1 RepliesI have have two radio button lists that need to be mutally exculisve, i.e when one is clicked the other one neesd to be cleared, my further problem is beause they are in a formview I had to add handlers to clear all the controls in the other list when the one is clicked and vice versa. here is the code below Now the code works but one of the testers found that if you click back and forth around twenty times you get the above java error:
Exception message: Maximum request length exceeded
my though here is the handler is being added to many times ? but even if I remove the handler after the process is complete I still get the same error.

I am converting a web forms site to MVC and there are a lot of pages all with an individual screenshot image on. Rather than have a separate page for each screenshot image, I though a better way to do this would be to have one page, and to pass the image details into a Controller method, and then set the src value of the <img> in my code. Does anybody know how to do this, and even if it is a good idea to be making reference to UI elements in my Controller code?

View 2 RepliesI've figured out how to create the controls in the format I want, but now I am confused as to how create more than one set of them. I set everything to new and increment the names of each control, but it's only updating the one set. Here is my code:

I created a new page in an existing project. The existing pages are still good, but the new page is having problems at runtime. The problem is that controls are not recognized and throw a "object reference not found" error. I even tried Page.FindControl and that didn't work either. This is only happening with this page. The controls are recognized at design time, and are not recognized only at runtime.
The controls were copied from a regular Web form into a content form with a master page. They worked fine when in the regular web form. Could that be the issue?
I tried creating a new page and moving the controls over, but that didn't fix the problem. I also tried deleting the designer file and recreating it (using convert to web application) but that didn't resolve it either. I'm out of ideas here. Here is the page directive and the first control that is not recognized.
<%@ Page Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="default_grid.aspx.cs" Inherits="TestItemDevelopment.default_grid" %>
<asp:Content ID="Content4" ContentPlaceHolderID="mainContentHolder" runat="server">
I am trying to create a datagrid with bound columns and template columns at runtime. I can successfully create the grid and columns if I only put one control per column, however, I have a need to place two controls in a single template column. If I create the column and controls at design time, it works fine as such:

My issue is trying to place both that label and dropdownlist into the same template column at runtime. Using code as follows, I can get one or the other successfully into the grid at runtime, but not both:

How can I add a second (ItemTemplate?) to that TemplateColumn? I tried:

but then only the dropdown list (the EditItem) shows in the grid at runtime.
If I have created a sub (VB) that creates a set of CheckBox controls at runtime, how would you suggest that I then read these controls into a 4 column table?

Dim chk As New CheckBox()
chk.ID = String.Format("chk{0}", i)
Form.Controls.Add(chk)
chk.Text = String.Format("column{0}", i)
Next i
End Sub
