View 1 RepliesI have an asp:table control that I construct dynamically. I place a few textboxes in it within a for loop and assign their IDs in code. I'll include an abbreviated code fragment showing how I'm doing this:
[Code]....
The page then displays correctly and the ID is set correctly when I view the source, but when I try to access the textbox later when the form is submitted the call to FindControl(idStr) returns null no matter what I do.
Im creating a table dynamically in my codebehind to display some statistics. The table is in a usercontrol. When the page first loads, its created and displayed correctly. If I do something that generates a postback, the table subsequently disappears, this is because its created inside a !IsPostback. How can i ensure that the table, once its been generated, stays visble on the page ? I dont want to generate it each time the page loads as it involves a lot of calculations on the database which will slow the pageload down.

How Can I do this ?
So today I started learning ASP.NET. Unfortunately I haven't found any good tutorials online, and I can't afford to buy books at the moment, so I've had to create a ASP.NET web application in Visual Studio 2010 and just play around with the default project setup. So far here's what I have in my Default.aspx:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="WebApplication1._Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

</head>
<body>
<div style="padding-bottom:10px;"> Project Management System</div>
<div> <table style="width:100%;">
<tr>
<td>Name</td>
<td>Task</td>
<td>Hours</td>
</tr>
</table></div>
</body>

I created a simple table with the header row already in there. Through a C# script, I want to be able to dynamically add rows to this HTML table. Is this the right way of thinking in ASP.NET? If so, how can I do this? I'm sure I'll need an "Add" button, which adds a new row to the table, with editable fields, and a "submit" button which adds some stuff to a database. Basically just a rundown of how this is done would be ever so helpful. Also if anyone knows any good tutorials or websites
inserting MAX ID into table dynamically
View 8 RepliesI need to show/hide a table-row upon the click of a linkbutton. I have gotten it to show the row when clicked, but instantly reverts back to being hidden. I have tried putting the CSS style display attribute in a numerous amount of ways and it is still not working.
This is my .aspx file:
[Code]....
This is the .js file that is properly imported:
[Code]....
When loading the page I have tried a numerous amount of ways to set the attribute to none, in the stylesheet, in the style attribute of the tag on the .aspx file, via a similar javascript function that hides the element. All of these show the same result, when clicking the button it simply reloads into being hidden after being changed.
how to add dynamically control to a table
View 3 RepliesDoes anyone know how to dynamically add and remove rows in a table triggered by a button click from the backend (in c#) using asp.net?
Here's how it might be done in javascript, is there any way to do this in the asp.net framework?
[URL]
Protected Sub btnAddRow7_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnAddRow7.Click
Dim tableRow As New System.Web.UI.WebControls.TableRow
Dim tableCell As New System.Web.UI.WebControls.TableCell
Dim textBox As New System.Web.UI.WebControls.TextBox
tableCell.Controls.Add(textBox)
tableRow.Cells.Add(tableCell)
tbl7.Rows.Add(tableRow)
End Sub
but it only adds one row dynamically. After the first addition, more clicks to the button will not add more rows.

I need to implement a search page where a user will be able to specify some search criteria and perform a search. It's a requirement that the results are displayed on the same page, beneath the search criteria.
Here's the code for the controller class:
[Code]....
For simplicity, the table string above is hard coded but would be constructed dynamically in the real code.
I also have the following form defined In the body of my html:
[Code]....
Finally, I'm using JQuery to hijack the submission of the form and to request the html for the table:
<script type="text/javascript" language="javascript">
$(document).ready(function() {
$("form[action$='GetTableData']").submit(function() {
$.post($(this).attr("action"), $(this).serialize(), function(response) {
$("#tablePanel").html(response);
});
return false;
});
})
</script>
I'm fairly new to ASP.NET and MVC but the thing that slightly bothers me is that the html is generated in the code-behind for the view.

And added controls to it in click event of one button as :
[Code]....
but i cant retrieve this controls in click event of another button. i think it is because of postback.
I am returning an IList to my model of data about users. I want my end users to be able to select which columns they want to see.
I know I can do this with a huge "if statement" however, I know there must be a better way. I have created an Enum with the column names. I feel if I could take the IListItem.EnumName I would be set. However, I'm not too sure on how to do this.
For every row in my 'table' I am manually creating, there must be a LinkButton to delete a database row that matches a column in the table. Because no 2 controls can have the same name, I've had to use a GUID to name them so they're all unique.
Problem is, right now when I click Delete, the page posts back with no changes, but I've been told that I need to recreate the controls - but how do I recreate them in Page_Load when their ID's are randomly generated? Here's my code:
