I have asp.net page on which I have placeholder and a button. After the button is clicked I want several LinkButtons to appear on my placeholder, and I want specyfic handler to be connected to click_event of my LinkButtons. Here is the code:
protected void Button_Click(object sender, EventArgs e)
{
for(...)
{
LinkButton l = new LinkButton();
l.ID = "link" + i;
l.Command += new CommandEventHandler(link_Command);
PlaceHolder1.Controls.Add(l);
}
}
void link_Command(object sender, CommandEventArgs e)
{
PlaceHolder1.Controls.Clear();
Label l = new Label();
l.Text = e.CommandArgument.ToString();
PlaceHolder1.Controls.Add(l);
}
The LinkButtons will be visible but their event won't fire. How should I solve this? I need to generate LinkButtons inside the Button_Click event, because only then I will know how many buttons to create.
I have a GridView control bound to an AccessDataSource. After selecting a row I'm creating a table inside the selected row. I'm adding Buttons to this table. Their Click event never gets fired. I read about recreating the buttons and stuff, but still no luck solving the issue.

I have a html table, which I created dynamically. I can add rows at run time in it.In each row I have a file upload control and an upload button by side of it in a cell.I want to know how can I handle the click event of these buttons because they are generated in a for loop dynamically.
1st row ... | btn | if a new row is added, 2nd row will be visible.
2nd row ... | btn |
I am adding some dynamic image buttons to a form in my code behind (vb.net) and added a click event handler, but it never fires. Also when I click on a button the page posts back and everything below my update panel disappears.

I am creating a button dynamically in my code and attaching a click event to it. However I have to prevent people to click it while there is a process going on. So when it is clicked once, it should be disabled and when the process ends it should be enabled. How can I do that?

On grid RowDataBound based on some condition i've added imagebutton dynamically. parallelly i want to add event for this button click. here is my code snippet.
protected void GV3_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
TableCell cell = new TableCell();
ImageButton bttn = new ImageButton();
[Code]...
That message popup box comes, but i'm unable to catch that click event. while click on a row i want to delete that row, so want to create event dynamically. for that i've used this following dynamic click event
bttn.Click += new ImageClickEventHandler(b_Click);
private void b_Click(object sender, EventArgs e)
{
//delete record
}
but this above code also not working.
I want to create a table on Oracle on a click event of a button on ASP.NET. My webpage need a dynamic structure of table creation on the back-end (which I have connected with Oracle database).Please suggest me how can I do this with ASP.NET application?
View 2 RepliesI just had a few questions about a basic version of the Singleton Method that is posted below. I've just created a very basic class that implements the Singleton Method. Afterwards, I create the first instance in the Page_Load and then when I push a button on the Web Page, I create a reference to the Singleton Class and then print out the "SingletonName" property to ensure that it has a value.
Code:
public sealed class Singleton
{
private static readonly Singleton instance = new Singleton();
[code]....
1) If 2 or more users are concurrently running this application, will the users have a new Singleton Object, or will the user be given the Objects that the first user created? In other words, is this Global to the application or just the session? I believe it is global for each session and not to the application but I wanted to make sure.
2) In the button click event, should you create a new reference, like I am doing, or should I do something like "Response.Write(Singleton.Instance.SingletonName)"?
the buttons are created fine, when i click a button i get my javascript alert, but my labels arent updated, its like the serverside function isnt running it at all
the "SetTemplateContent" section the aspx section is at the bottom if that helps
whats up with the code that would be great, cheers

I am not sure how to do this. I have part of it working and I think I understand why it isn't working, I just not sure what I have to do to fix it... I am dynamically placing some data into an ASP:Table from a DataSet. This is all done from the Page_Loud event. I am looping through the dataset by going through the rows no problem to display the data in cells added by rows to the asp:table.
What I am also doing though is adding a button for each row that is to run an Access insert query that adds a record in a log table.I have used the following code to get this to work which it does, most of this is called through functions in the Page_loud event. this is the gist of it:
this is in a loop of the DataSet
for (int i = 0; i < dsResult.Tables[0].Rows.Count - 1; i++)
{
Button btn = new Button();
btn.Text = strDynamicText;
intTID = dsResult.Tables[0].Rows[i].ItemArray[5].ToString();
[Code]....
Here is the problem I am having. The button does display for each row, and the query does execute and run when I press the button. The values being passed in intTID and intUserGroup (are global), are suppose to be different for each row though, and are to insert a unique table ID, and a different group depending on what is in the dataset. Problem is, it is only assigning the last tableID from the result set into the button and will always pass that same ID no matter what button is pressed. This is the same with the intUserGroup. It needs to dynamically have differnent table IDs passed but that's not happening. What do I have to do differently to make sure that when the button is created dynamically it will pass the unique values for each row?
I have a dropdownlist("ddlTemplate") control and a gridview("gvPlanning") control with 1 BoundField column, 1 TemplateField column and remaining columns will be generated dynamically from database.In TemplateFiled Column i have 3 image buttons viz: Edit, update and cancel.Gridview will be populated based on the selecteditem of dropdownlist.
if i click on edit imagebutton, i need to add textboxes dynamically in all the columns of that row except first 2 column. And if i click on Update imagebutton i need to retrieve the textbox values.we can add template field column for textboxes also, but why i am sticking to this method is.. the number of columns changes depending on the selecteditem from the dropdownlist. Eg: If i select india from dropdownlist the number of columns in the gridview would be 4 and if i select UK from dropdownlist the number of columns would be 9 likewise.
Creating a list of users with a "Delete" linkbutton next to each". Seems I got it all wrong (again..away from webforms a long time).
Here's what I do:
Building a list of users with delete buttons:
Code:
foreach (var user in users)
{
var usr = user as UserInfo;
var row = new TableRow();
var cell = new TableCell();
[Code] ....
The "Delete""event handler:
Code:
protected void btnRemoveModUser_Click(object sender, EventArgs e)
{
var button = sender as LinkButton;
var userController = new UserController();
var user = userController.GetUser(PortalId, int.Parse(button.CommandArgument));
RemoveUserFromRole(Enums.KnowledgebaseRole.KB_Moderators, user);
}
I got a hunch though it's because of the when/where I'm loading that list of users. I call the function (getting a list of all users, clearing the table and populate it again):
In the page load, if not a postback.
Every time the "Add user" function have been called (that works fine).
Every time the "Delete user" function are called.
The last will not delete the user (still in database) but reload the ^&* form without any users.
I just found that the delete handler does not get called at all, but the button post back the form, so my list of user's don't get loaded.
I want to dynamically build a table where each of the first three cells may or may not contain an image. If a cell contains an image, it may or may not contain a radio button. The last cell contains a button or link button. I want all the buttons to be handled by the same click event. The number of rows, which cells will have an image, and which cells will have a radio button is not known at design time. Finally, the images are displayed using the better image control.
I'm trying to get this to work usinging a repeater, but at the moment I can't get the radio button checked propety to change from the default value. I'm using an arraylist as a datasource. I thought of using a gridview, but I don't know how to add a radio button and a better image control to a cell.
I have searched around but unable to find a solution that will work. I have a link button that is created dynamically during the page load. It is given an ID (obviously). There is a script manager on the page. I have the controls added to a panel in the updatepanel (updatePanel1). There is a dynamic label that is also created with each link button. I can get a response from the linkbutton click event during a postback on the second time clicking the linkbutton, but I am getting a complete postback instead of the asyncpostback for that control. During the creation of the dynamic linkbuttons, I am also creating a dynamic trigger for each button and adding it to the updatePanel1. The Click event is not firing the method without doing a complete page postback.
View 4 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.

This event handler is not responding at all to the click event. On click, the pagination numbers disappear and I'm not able to trace it in the debugger because the event handle doesn't even fire so I have no idea what's going on.
