C# - Dynamic LinkButtons Click Event - How Many Buttons To Create

Jul 7, 2010

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.

Web Forms :: Button Click Event Not Getting Called Due To Tag?

Feb 23, 2010

In my web form, i am having button named "btnSave" and there are some textbox controls (to name few, Emp Number, Full Name, etc). I've added RegexValidator to the textbox controls as below:

<asp:RegularExpressionValidator
ID="employeeNumberValidator"
ValidationExpression="^[0-9]+$"
ControlToValidate="txtEmpNumber"
ErrorMessage="Only integers are allowed"
runat="server">
</asp:RegularExpressionValidator>

This RegexValidator will check for emp number textbox contains only integers and if not, it will display message "Only integers are allowed". Now, in my btnSave_Click(...) event, i am first validating whether the textbox contains data and if not, then i am highlighting the textbox in red. When txtEmpNumber contains non-integers data and if i click the Save button, the code in inside btnSave_Click(...) event is not getting called. But when i provide employee number in expected format and then click Save button, then the code inside button click event is getting called without any issues.

I am not sure why my btnSave_Click(...) is not functioning when Employee Number has data in incorrect format.

Web Forms :: Dynamic Buttons With Event Handling?

Mar 1, 2010

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?

Web Forms :: Button Click Event Is Called Before Page Load?

Oct 8, 2010

I just discover why some validation is working bad on some of my forms: the button click event is being called before page load.

What I need for good is (I consider this is a normal cycle of events):

The user press a buttonSome validation occurs at client side (js function returns true if success)Some validation occurs at server sideThe page loads again showing the results
But this is what I get (BAD):

The user press a buttonSome validation occurs at client side (js function returns true if success)The page loads showing no results, because server validation hasnt happened yet Some validation occurs at server sideThe page doesnīt loads again and I cant see the results, so my client cant know what happened on the server side

This is how I tried to implement this:

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.

VS 2010 - Dynamic List Of Delete Buttons / Event Handler

Oct 14, 2011

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.

AJAX :: Trigger Event Added To Dynamic LinkButton Click Event?

Jun 25, 2010

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.

Forms Data Controls :: Dynamic LinkButton Click Event Won't Fire?

Dec 21, 2010

I am working on an ASP.NET web application using .net 4.0 and VS2010.

I have a GridView and I am appending a row at the bottom to allow users to input data for "Adding" a new record.

The ONLY way I have found for this to work is to do this in the RowDataBound event of the grid. I can check to see if it is about to process the footer row then I know I am at the bottom and can insert this new row.

The row I am inserting contains a couple of TextBoxes and a LinkButton for the "Add" link.

If I just drop a LinkButton on my form and hook up the click event and I click the link button then the first thing that fires is the Page_Load event then my click event. However what is happening when I click the link button that was dynamically added to the GridView is the Page_Load event fires but the click event never does.

I have read 1000 threads saying to try to create the controls in the preinit() or some other event. In my case I can't. Or else someone would have to explain how to add the row to the bottom of the databound GridView.

Here is my code: (I removed creating the Textboxes because that is not part of the problem.

C# - Dynamic PDF Generation From Template?

Jan 26, 2010

I've a requirement to be able to generate PDF's within our (ASP.net) application. We need to meet the following requirements:

The text will be largely dynamic and must be added programatically. we'd like to base these generated documents off PDF templates provided by our designers. Some of the sections/pages may or may not be visible depending on certain conditions - we'd like the content to 'flow' upwards to fill the space when something is removed. Some of the pages may need to repeat, depending on certain conditions.Some of the PDF templates will be out of our control (we're populating application forms supplied by third parties), so being able to read in a blank PDF and populate it would be good.

I've looked at iTextSharp and it seems to do most of these things (i.e. I can take a PDF, edit it to include form fields where we need to fill data and then use iTextSharp to read that in as a template and populate the data), however, I'm not sure how then to go about potentially hiding whole sections and/or repeating pages.
