I need several buttons on each GridView row that redirect to pages performing custom operations. How do I get the DataKey of the row the button was clicked on? So that I can send the database ID of the row I want to perform operations on to another page. I can't use GridView.SelectedDataKey.Value because i'm not always going to be clicking the select button. Nor can I use the index, because that is not the ID for the data in the database.

Nevermind.  This is how I did it. If someone knows a better way, lemme know.
I created a button commandField with command "EditRow" and hooked up the RowCommand event.
<code>
protected void MainGrid_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "EditRow")
{
DataKey mykey = MainGrid.DataKeys[Convert.ToInt32(e.CommandArgument)];
String mystring = Convert.ToString(mykey.Value);
Page.Response.Redirect("Insert.aspx?key=" + mystring);
}
}
</code>

I have added the script below to my website and if it is in test mode, it works fine - it writes the data to the screen. But when I take it out of test mode, it doesn't email me the data. I have pasted the script along with my code for the form. Can someone please tell me why it's not emailing? (Also, fyi, I do have a .txt file setup for the formatting of the email.) Thank you!

I am getting the error:
The process cannot access the file 'D:\KBF\WebSite\Project\KBF20071109\Images\Icon_Restricted.gif' because it is being used by another process
while trying to replace it with a new one. The reason is because it is currently displayed in an Asp:Image control. I want to replace it while it is being displaed. I tried to replace it in a button's click event just after reseting the Image control's path in the same event but the same error.

Hello
Dear Michael
I'm a professional desktop developer (C# base), but in sending mail, i really confused.
I developed a website for somebody and i'm in final step.
As you said and in this way anybody can send email from anybody to anybody..!
I want to say that: Do i need username, password and real host name or not?
I tested this code and i saw no mail in my inbox. Please notice that i made no change on your code.
So please help me again if you have time.

Hi,

You need to define the host name, the SMTP server.... In ASP.NET, you can use either System.Web.Mail or System.Net.Mail for sending emails.. but defining the SMTP server is a must in ASP.NET...
The name of SmtpServer are vary from one host to another.. When I was hosting my site in DisccountASP.NET, I can use "localhost" as the SmtpServer... here is the article from DiscountASP.NET Knowledge Base.

Your web host is the best contact to give you the optimal values for these queries for your domain.

I'm using a CAPTCHA image generator from Code Project and would like to wrap this in to a web control.
So I was wondering what's the best way to display a dynamic image from a memorystream? Currently I'm setting the img src to a handler which works fine. But the handler needs to be a servable page and can't be wrapped in to a control dll. I'd prefer not to write the image to a temp directory. Is there an alternative or a nifty trick like putting the handler in as a resource in the dll?

Ehhh, I'm already using a httphandler (ashx). That's the problem, you can't wrap an ashx page in a web control dll. It has to be a servable page on the actual website.
The point of my question is how to achieve this functionality within a seperate web control dll.

Hi,
I have a page that is pretty complex, i.e. it has a table with lots of controls, everything generated from data in a database. Each row contains among others a DropDownList, and when certain items are selected in that dropdownlist, the rest of that row should be disabled. The rest of that row contains text boxes, drop down lists, and a few validators. The number of controls is dynamic.
What would be the best way to accomplish this? What I've got so far is:
- a onChange attribute for the dropdownlist,
- a javascript function which gets called in the onChange event handler
- this function correctly determines if I should enable or disable the rest of the row
- ... and then calls getElementsByName to get an array of elements that should be enabled/disabled.
But this is where I stop, since getElementsByName doesn't return anything. If I specify a name attribute for the controls that should be enabled/disabled, it won't render to the page since ASP.NET will override my setting with the id of the control. I could probably create a subclass of TextBox and DropDownList, and modify their RenderAttributes( ) function, I just haven't gotten to it yet. Is there an easier way?
Even if I succeed with that, I still have the problem of disabling the validators for the controls that should be disabled. Is there some easy way to accomplish that? I found http://www.codeproject.com/useritems/ASPNET_Validation_Tamed.asp[^] which talks about similar solution, but am I missing something completely obvious? I'm aware of the fact that I could set the AutoPostBack property of the DropDownLists to true, and handle the change events server side, but I would rather do it client side just to minimize server load. But then again, if I must use server side I probably will.
So anyway, any help or hints whatsoever would be highly appreciated.
Regards,
Daníel

Sorry. I forget your last post...
Steps:
1. Add one button and one Literal control.
2. In Button_click
2.1. Get the completed embed object tag from database depend on the parameter
2.2. Set the string to Literal1.Text (e.g. Literal1.Text = @" EMBEDDED TAG FROM DATABASE";)
That's all.. Let me know if you are not clear

Hi,
Please Explain some more...if am taking object tag from database and assigned to Literal.How is the movie working?If I need to assign only the object tag to Litteral.am i correct?
Thanks
