I have a web user control with dynamic LinkButton think an event in which you assign events to them (LinkButton.Click + = new EventHandler (Method)).The problem is that these events do not run, I did test creating and if you run statically.Why is it??I need to be created dynamically at runtime.For Examples :
for (int i = 0; i <= 5; i++)
{
Button boton = new Button();
[code]...
I hv created a menu during runtime.. my menu items are from the database. . wen i click the particular menu item, it shud redirect me to the related webpage. .
I wanna know how can i make menuitemclick event fired... nd how can i set different redirect webpages for different menu items as all the menu items r loaded at runtime..
I have an unbound gridview which is bound to a dynamically created datatable during the pageload event of my page. A simple matrix with x columns and y rows. I need all the cells to be the same size. I'll display my code below.
[Code]...
I am dynamically creating my grid view as:
HyperLinkColum hlc = new HyperLinkColum();
hlc.Datatext.DataTextField = "PK";
myGridView.Colums.Add(hlc);
I wanted to call a page say "test.aspx" and to send the primary key of the relevant row to the "test.aspx" page and then how to retrieve this values in the "test.aspx" page
I have a question connected with controls and event handling. Lets say I want to create a LinkButton.
protected void loadLinkButton()
{
ContentPlaceHolder content = (ContentPlaceHolder)this.Master.FindControl("MainContent");
LinkButton lnk = new LinkButton();
lnk.ID = "lnikBtn";
lnk.Text = "LinkButton";
lnk.Click += new System.EventHandler(lnk_Click);
content.Controls.Add(lnk);
}
Here is the event handler:
protected void lnk_Click(object sender, EventArgs e)
{
Label1.Text = "ok!";
}
If I run the loadLinkButton function inside Page_Load everything is ok. But when I try to run the loadLinkButton by clicking simple button, link button is created but event is not handled.
protected void Button1_Click(object sender, EventArgs e)
{
loadLinkButton();
}
I there any way to solve it? Or loadLinkButton must always regenerated on Page_Load, Page_init etc.
I have a listview that displays a list of textboxes that get created on a button click. I would also like a label to be created next to each txtbox that would increment what is says from step x: to step x+1:
Do I need to create another listview control for this, or is there a much easier way (which I hope)?
Here is the current web code for my listview:
<tr align="center" valign="middle">
<td>
<asp:ListView ID="lvDynamicTextboxes" runat="server" ItemPlaceholderID="itemPlaceholder" onitemdatabound="lvDynamicTextboxes_ItemDataBound">[code]....
And here is the code-behind
protected void btnAddNewStep_Click( object sender, EventArgs e )
{
this.UpdateDataSource();
this.IncrementTextboxCount(); [code]....
EDIT::Since there seems to be a bit of confusion, I'll try to clarify:As of now, I have a textbox in a listview with a button underneath.
________
| txtbox |
|________|
_____
|_btn_|
When you click a button, it generates another text box, so clicking it twice results in this:
________
| txtbox |
|________|
________
| txtbox |
|________|
________
| txtbox |
|________|
_____
|_btn_|
These textboxes are to create steps in a process, so all I would like to do is add a generated label next to each generated textbox to say which step it is. So I want it to look like this:
________
["Step 1"] | txtbox |
|________|
________
["Step 2"] | txtbox |
|________|
________
["Step 3"] | txtbox |
|________|
_____
|_btn_|
And if they click the button again, then another label is generated with the text "Step 4"
For test purposes I have created a simple button control that extends CompositeControl. I am able to place it on the page with a <asp:Content... and the Click event Bubbles without problem from the Control.
Now, here is the problem I am facing Due to design requirement I need to read the assembly and the classname from a table and dynamically create the control and add it to the <asp:Content. And when I do that the click event will not fire! Where am I going wrong.
Here is the code in the ButtonControl.cs
namespace Reports.Web.ServerControls {
[DefaultProperty("Text")]
[ToolboxData("<{0}:ButtonControl runat=server></{0}:ButtonControl>")]
public class ButtonControl : CompositeControl {
protected override void CreateChildControls() {
Button btn = new Button();

View 3 RepliesDoes anyone have a good vb example of adding an "onClick" event to a button that is dynamically added into a templatefield of a gridview. MSDN just says to use the addhandler statement with no other good info for a 'dynamic' scenario:

I'm creating some linkbuttons dynamically and assigning properties like below. Also I'm adding an event handler to the created link button:
[Code]....
What happens here is when the links created at runtime are clicked, most of the links are linked to other applications. (e.g from app1 to app2, app1 to app3 etc..) So when moving from the current app to the next I want to abandon the current session. However, this event is not firing before navigating to the next page. Could someone suggest a workaraound or the correct way to accomplish that?
I have a page that contains many textboxes. It is like 9 textboxes for everyday in a month, and their numbers and IDs are changing dynamically for every month change on the page. I'm creating them in many for loops like;

View 3 RepliesI've created an array of buttons like static Button[] myButtons = new Button[3];
and then creating and adding buttons to my panel like myButtons[i] = new Button();

How can I handle the events that occurs when a user clicks these buttons, like using OnClick="myMethod" with regular buttons?
I have a accordion control inside an update panel. As I loop through the Products table and the Details table in the code behind, I'm creating the accordion panes that will display the data. There's an "Add to Cart" button created for each product (each accordion pane), and I'm asigning an EventHandler for that button, but it never fires... Here's the code where I'm creating and adding the button to the page:

I Need to create the Dynamical webpage(.aspx) at runtime.
View 1 RepliesI'm trying to create a button dynamically with event by original button. The original button's click event response creates a button. The new button has a click event attached with a test message.What I have to do is onclick change background color of dynamically created button and grab id value to delete when button delete is clicked. Unfortunately, when I click the dynamically attached button, nothing happens.

My page contains a button [Button1].I've dynamically created a new button [Button2] in the Button1_Click event and and assigned event handler also.But when clicking on Button2, Button2_Click event is not fired.I think its because the page looses dynamically created Button2 after post back, since it is created in Button1_Click event.Is there any way to maintain Button2 on page and raise Button2_Click event ?
View 5 RepliesI am adding numerical page links for paging of a repeater. I have used on of the numerical paging samples as my base. It works fine if I have less pages than my maximum total links. Eg if I have 11 pages, but only showing page 1-10 plus a next for the 11th, I get an error about duplicate control ids. I changed my control id to use a Guid in the string to keep it unque, after making this change the event handler never fires
private LinkButton createButton(string title, int index)
LinkButton lnk = new LinkButton();
//lnk.ID = System.Guid.NewGuid().ToString("N") + "_" + index.ToString();//Event does not fire if I set ID with Guid

I am creating n number of Combo boxes dynamically at run time and adding a Handler of Combo1_SelectedIndexChanged() to the combo boxes.
At run time, When I select an item from one of the Combo boxes, the event fires n times rather than 1.
So for example : If there are 5 combos created, and I select an item from my first combo, the event Combo1_SelectedIndexChanged() , fires 5 times and that is an issue for me. How can I restrict this to run only for the combo that I selected.
I am creating two buttons within the StoryGet() method, first when the page loads. When one of the buttons is pushed, lets say the left one - I want to call another method - "ButtonLeft_Click"
Ive used this same solution in other sites and it worked. With this solution, click event never fires.
If I move the StoryGet() call from Page_Load to PageInit() the button event fires, but because this event also calls StoryGet() the method runs twice, which I don't want.
I tried adding this to page_init so the original StoryGet() method only gets run the first time the page loads unless the method is called directly but then the page loads, but the button click event doesn't run again
if (!this.IsPostBack)
{
piccount = 0;
StoryGet();
}
