Hi,
Language: Visual Studio 2.0, ASP.Net, C#
Case:
1) Datagrid Bound columns generated at runtime and populated from the dataset.
2) Datagrid contains a select button. When the select button is pressed a new report is generated.
Problem: During the first page_load grid is populated properly but when it is postback Datagrids items and cells are not visible in the select buttons itemcommand method.
I know ASP.NET 2.0 uses partial classes, but
how the old InitializeComponent method
can be eliminate from the code-behind class and partial
class be used in its place?
A quick reply will be really helpful.
Please feel free to revert in case of any clarification.
Thanks!

The problem is ASP.NET is not maintaining viewstate for the controls created runtime. I assume that you are creating columns in page_load. When page_load event raises, ASP.NET had already loaded viewstate for the controls. So to solve your problem, you need to bind your grid before page_load event. Then ASP.NET will maintain viewstate for your dynamic controls. May be PreLoad event.

Thanks for your reply Navaneeth,
The solution u provided is not working. I am creating the Bound columns at runtime from a method which i am calling in the page_load if the page is not postback. By referring the articles in the google i came to know that i should not be using page_load, instead i should call the method in the initializecomponent() , but since i am working on .Net 2.0 it does not have initializecomponent method.
Thanks

Try PreLoad event, This is new to ASP.NET 2.0

Hi there, are u getting the dat set on page load. if yes than i think this will not create problem.
Also u can try with calling the loadgrid function on page load as well as rowitem command.
better way to create function and call it any where u want and seems creating problem.
this is final solution

Navaneeth, I have tried PreLoad and its not working.
Please find below my sample code so that u get a better idea.
protected void Page_PreLoad(object sender, EventArgs e)
{
if (!IsPostBack)
{ getdata(); }
.....
}
public virtual void grdvwCheckbox_ItemCommand(object s, DataGridCommandEventArgs e)
{
if (e.CommandName == "Select")
{
e.Item.BackColor = System.Drawing.Color.Wheat;
DataGrid dg = (DataGrid) s;
.........
}
}
public void getdata()
{
DataSet ds = new DataSet();
string rptDetails;
rptDetails = txtRptDetails.Text;
GridReports objBO = new GridReports();
ds = (DataSet)objBO.GridData(rptDetails);
grdvwCheckbox.AutoGenerateColumns = false;
foreach (DataColumn c in ds.Tables[0].Columns)
{
grdvwCheckbox.Columns.Add(CreateBoundColumns(c));
}
...................
}
Hope this helps u to help me.
If u have any working sample code in .Net 2.0 where Bound columns are created at runtime and ItemCommand event
is fired then please forward it to me.
Thanks guys for your reply!

May be u have put some contentplaceholder or something and changed the name of the control later since controls are named with outercontrols prefixed when used with Masterpages.

Been trying find a way to update a form ( same instance) directly from a class.My example below compiles but the form result leaves the textbox blank. Can anyone help? I'm new to this so go easy on me.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
namespace test1
{
public partial class Form1 : Form
{
public string strStringVarible;
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
}
private void button1_Click(object sender, EventArgs e)
{
classtest1 clstest = new classtest1();
clstest.external_class();
}
public void accessor_method()
{
this.textBox1.Text = strStringVarible;
this.textBox1.Refresh();
}
private void textBox1_TextChanged(object sender, EventArgs e)
{
}
}
}

namespace test1
{
class classtest1 : Form1

{
this.strStringVarible = "test123";
this.accessor_method();
}
}
}

Hi,
classtest1 and Form1 are two different classes and do not represent the same object. You are creating a new instance of classtest1 in classtest1 clstest = new classtest1(). This would automatically create a new object and so any calls to methods in that object will not affect the one it inherits from. This also means that they represent 2 distinct references.
What is happening here is that the textbox of clstest is getting the value test123 but since the form (which is not the same as Form1) is not displayed, you cannot see the change.
A second opinion on that would be nice just to make sure I didn't miss anything

Thank you.
I see what you're saying but all I want to do is update a control and it appears to be more hassle than I anticipated. so how do I reference to the same instance. or am I completely misunderstanding you

Talal already given the solution to you. I am reiterating, value is assigning to your textbox. But as you inherited form1 in your class, a new object will be created and that is not same where u r textbox relies.
You can rewrite your external_class function like this
public void external_class(Form1 frm)
{
frm.strStringVarible = "test123";
frm.accessor_method();
}
Hardboiled86 wrote: classtest1 clstest = new classtest1();
clstest.external_class();
Rewrite this like
classtest1 clstest = new classtest1();
clstest.external_class(this);
Hope this helps

I've seen a lot of people on other forums trying to do exactly the same but being given all kinds of wrong answers that don't work. If anyone is googling this, this answer does work. Fact!

difference between master page and user control
plz let me know

A master page is a, er, Master Page, and a User Control is a, um, User Control!
Or you could try Google[^] when doing homework...

Hi all,
I'm using "Directory.delete(folderpath,true)" for deleting a folder containing sub folders and files from server. When i'm trying to delete it, it throws an error saying 'Directory not empty'. All the files and subfolders are getting deleted, but the directory is still there. More over, it removes all the session variables also. How can i fix this issue? Please help.

Is it deleting ASP.NET folders like app_code, app_browser ,bin. Then application will restart and that will end all sessions.

No.. it deletes a user folder only.

Impossible until you get HTTPPostedFile object. May be possible with some activex controls.
Reason is, ASP.NET won't be having access to the file paths listed in the listbox. So it can't read files for upload. Instead of this you can use datagrid/gridview. Put a template column contains file upload control. Iterate through all the rows of grid and get fileuploadcontrol object, do the upload.
