Web Forms :: Can Process Multiple Buttons With One Click Event
Sep 23, 2010
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 an unknown number of image buttons inserted into a Placeholder at runtime during a webpage's Init stage. I would like to use a single event handler routine in C# language to determine which control was clicked and process any one of them differently. How do you create an event handler to process whichever image button that is clicked?

the form has 15 items to choose with radio buttons, any number can be selected. I would like to process them as a 'group' so I can do something like loop thru them, checking if each one has been selected to build a list and also be saving them to a table row, etc but it seems all the designations as a list or group make it mutually exclusive. just looking for better coding than checking them with an if statement or similar so the question is if there is some way to designate the radio buttons as a group but no force the group to be mutually exclusive

I'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.

The books are stored as objects within the session.The trouble I am having is when a user clicks on the "Delete" button, how do I pass the ISBN value to the onclick method. Can someone kindly tell me the best way to achieve this?I tried doing it below but am going nowhere.

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 dropdown list that contains a collection of names. My entire names list is very large (over 2,000) so I would like to pair down the names in the drop down list to those starting with the same letter.To do this I would like to have 26 links all on the same line, one for each letter in the alphabet ..
A|B|C|D|E|F|G|H|I|J|K|L|M|N|O|P|Q|R|S|T|U|V|W|X|Y|Z
The idea being that the user clicks on the letter they are interested in and the stored procedure that obtains the list of names is re-executed to only grab those names starting with the letter that was clicked and then the resulting dataset is rebound to the dropdown list.
What is vexing me is how to handle creating all the "Click Events" necessary to deal with the user "clicking" on a link. I could create 26 different event handlers, one for each link, but I have to believe there is a simpler way I am not seeing.Form demonstration here is the click event for one link, the letter "A" ...
Protected Sub lnkLetterA_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles lnkLeterA.Click
Call LoadNamesIntoDropDown("A")
End Sub
Is there a way to create one event handler that could handle all 26 links?

Since i have 5 buttons that pretty much run the same code, except for the database updates, i found some examples of how to do this.. so i created 1 button event, and put my general calc code then some if statements to determine what button was clicked.. but doing this now i get a NullReferenceException
and here is the code its complaining about, why would this work within the other button events, but not this one? Ive compared and and all the buttons on the page are the same with the except of the database entries.
Button b = (Button)sender;
Label tfive = (Label)FormView1.FindControl("five");
Label ttwo = (Label)FormView1.FindControl("two");

I have a scenario where...
1.) Have created a div with a dropdown list and ok, cancel button
2.) On document ready - registering div created on step 1 into a jQuery dialog
3.) on a javascript button click - I am opening this dialog box.
4.) Now, the problem is - the jQuery dialogbox which I have created, needs to be used by other button clicks as well on same page. Now, my div's (which is a dialog at runtime using jQuery) ok button click is already engaged with a javascript function (button1 click) and I can not associate other button's click events with it - thus stuck up here and have no clues or hit to resolve this.

I've found posts about making a click event with jQuery for a button, however I need a little more then that. When any postback occurs on a page, I need to fire off a jQuery click event. Based on a condition, I want to continue processing (including running the server-side event code after the jQuery code), or, perform a redirect. I'm not quite sure how to go about this.

I am listing about 20 rows, each row represents an Order.Each row needs to have 3 buttons, each button click will perform a different action.I have 3 actions to handle each button post request, I am just unsure how to setup the Html forms for each button.
<tr>
<td>
<form method="post" action="/orders/do1"><input type=button ... /></form>
<form method="post" action="/orders/do2"><input type=button ... /></form> [code]....
Should I create 3 forms for each button, per row in my listing?(that would mean 20 rows x 3 forms = 60 forms on a page)Is that 'ok' to do? (i.e. or is there a better way to do this?)

We need assistance with a portion of a major web application project scheduled to begin user testing within 10 days. The troublesome part of the code calls an external application when a button is clicked in Web page. When run from a command prompt or bat file, the external application, App.exe, runs perfectly producing the desired result. We created a test page and a small console application, Con.exe, to test the button code with a known quantity. The test application runs perfectly when the button in the Web page is clicked. However when we change the code to run App.exe instead of Con.exe, the App.exe code will not execute. We even tried creating a bat file to execute App.exe. Like the exe, the bat file executes from the command prompt or when double-clicked,but fails to run when called as a process from the button click event. Can anyone assist us? Here is the C# code: (.Net 3.5 sp1)

using System.Configuration;
using System.Data;
using System.Linq;

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?
