You can't. You can draw a chart from the data source, the grid is another view of hte data. You can write your own code using SVG, or, more likely, GDI+. Or you can buy a library, like Dundas Charts, or look over the web for a free one.

ASP.NET is irrelevant, as your web tier won't do this. So, it's all done by your codebehind, and the code is the same either way. The easiest way to put data in Excel is to write it as a CSV file ( comma seperated values ). Excel will turn these into columns. Otherwise, you can interop with Excel to do something more fancy.

You need to configure IIS for this ( just google, the main thing is you need to create a dummy certificate for testing ). your other issue is, you must always use full, not relative, URLs to navigate away from the HTTPS part of your site, otherwise, it will stay HTTPS

Hi there
I would like to use a expanding panel on my page which looks just like the tabs at the top of mozilla or IE7, except that it runs down the page instead of across the top, and when a tab is selected it opens left to right, as if coming out of the left side of the screen. Preferably when it opens it should give a similar effect to the AJAX collapsable panel with a fade smooth fade in and out, or for those of you who have seen the XBOX360 interfaces tabbing system, then similar to that. The AJAX panel unfortunately only moves up and down. Does anyone have any code which they have used before to accomplish something similar or have a link to a tool which can provide this feature???
Any help would be greatly appreciated as I am out of ideas of where to look, or what to search for.
Thanks...
Dev

Sounds like you have bandwidth issues. So long as you're not using SQL Server Express Edition, there's no generic reason for you to have this issue that can be solved in code or in your config.

Make sure you include the javascript file in your page, which I guess you already have done so...
Then.. in your jscript1 function. When you do the validaction to check the input, did you pass in the form name?
Example, if you have such code: form1.txtTextBox.value = "xxx"; Then you need to make sure in your form2 and form3, you have the same form name, "form1".

Hello All,
I am trying to integrate blogs in my application but iam getting an error
The error what iam getting is mentioned below
It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS.
Please help me in fixing this error
Thanks & Regards

It means you have an asp.net app in a subdirectory, and like the error says, you need to configure a virtual directory at that subdir level in IIS

Hi,
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.
Language: Visual Studio 2.0, ASP.Net, C#
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.
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. I have also tried PreLoad and its not working.
Please find below my sample code so that u get a better idea.
--Sample Code Starts Here
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));
}
...................
}
--Sample Code Ends Here
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.
A quick reply will be really helpful.
Please feel free to revert in case of any clarification.
Thanks!

If it is not working on preload, try Init
protected void Page_Init(object sender, EventArgs e)
{
Initialize your control here
}

Thanks for your reply,
It is not working with Init. If u have any working sample code in .Net 2.0 where Bound columns
are created at runtime and ItemCommand event is fired then it might help.

Anees

It will if you remove postback checking. Remove !IsPostBack when calling getData();

Great show sir, it does work. Thanks.
But the only problem now is that for every ItemCommand event it will make a round to the database which will be very costly in my case where the reports are huge. So apart from this is there any other way round to achieve the same results.
Anyways i really appreciate your help and support. Thanks a ton.

Anees

You can cache the dataset. This will avoid round trip to server

I created a class which checks session and redirects to login page. My class looks like this. This class inherits Page class to get access to session object.
public class CAuthentication:System.Web.UI.page
{
public CAuthentication()
{
if ( Session["login"] == null )
Response.Redirect("expired.aspx");
}
}
My ASPX.CS looks like
public partial class MyPage:CAuthentication
{
}
This is not working. I am getting error "session can't be used inside a class". What is wrong here ? Normally codebehind file used to inherit System.Web.UI.Page, Instead of this I inherited this in my CAuthentication class. Where I am going wrong ?

Please check it with HttpContext.Current.Session["login"].
