Basically, you can dynamically create the last column containing the DropDownList/ListBox control, then add it to the Columns collection of the datagrid control. To create the custom column, you have two options:
+ You can create a custom template column which implements the ITemplate interface, you can see more info from the article[^]. The downside of this way is that you cannot handle the postback event of the dropdownlis/listbox control if you want to do that.
+ Another option is that your custom control can inherit from the DataGridColumn class, and override the InitializeCell method to add the dropdownlist/listbox control to the table cell.

when i try to upload the file it gives error "Access denied".
then it gives me solution to change the rights of folder going into the security tab.
when i goto the property of project it shows me only four tab.....
General -- Sharing --WebSharing---Customize.
no security Tab.
what should i do to resolve this Error.

The error is suggesting that your ASP.NET application does not have priveledges to write to the upload folder - you indicate that you were looking at the "property of project" - did you mean the properties of the upload folder?
What operating system are you running? Are you using NTFS for the file system?

Ouch. You just gave the entire world write permission to the folder.
If the file system is not NTFS, it is not a permission problem. A FAT disk has no permission system at all.

Also, you might want to check this condition: if your machine (XP) is not joined to a domain, then you don't see the Security tab by default. If this is the case, you can display this tab as below:
+ Go to the Folder Options dialog (you can see this in Control Panel, or in the Tools menu of the Window Explorer).
+ In the View tab, under the Advanced Settings, uncheck the "Use simple file sharing (Recommended)" option.

I have no idea what your talking about.
"the problem is how to write the code to update the data on the page"
Cant you put it in the code in the:
Private Sub DropDownList_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles DropDownList.SelectedIndexChanged
?????

Change your submit button from an HTML button to an ASP.NET server control <asp:Button runat="server"/>. Create an event handler for its OnClick event and put your update code there.

By the way, you might want to refrain from adding things like "It is very very urgent for my project.I need it badly." to your forum posts. That's a good way to get your message ignored.

I see no mention in your original post that you "cannot change html button to asp button". There was nothing in your original post that "clearly" indicated anything of the sort.
Uma Kameswari wrote: I have javascript validators
No problem. Lots of ASP.NET pages use custom client side javascript for validation. You can use the OnClientClick property of the <asp:Button /> to run your javascript validation.
My original suggestion stands. In my opinion, your best course of action is to code an event handler for the Click event of your submit button (making it an <asp:Button />) and perform your database update in that code.

ok Mr.Mike I will check it tomorrow .

Hello Mr.Mike,
Can u tell me how to use the onClientClick property of <asp:button>
|
|
|
|
|
Sure - it's an ASP.NET 2.0 property, and you simply assign the javascript you want rendered as part of the client-side onclick javascript event.
The MSDN documentation for OnClientClick[^] has a good example.

I am developing an application on my local machine in the office in asp.net 2.0 to send emails.
The application is now able to send emails to external and NOT to internal email addresses.
Do you know what is wrong please?
Thanks
|
|
|
|
|
These types of things often turn out to be SMTP configuration. Are you running your own SMTP server? Is someone else responsible for the SMTP server for "internal" email addresses?
|
|
|
|
|
I don't know.
I am running the application (Which I am developing) in my machine.
If the site is sending emails externally the why it does not send emails to anyone internally?
Thanks

You have to know what SMTP server you are using.
fmardani wrote: If the site is sending emails externally the why it does not send emails to anyone internally?
System administrators can establish different rules for different SMTP servers. It may be that your organization's email server has restrictions on who is allowed to use it as a relay. You need to check with your SMTP system administrator(s).

I think you can set the EditIndex[^] property of the GridView to -1.
