Please share the code that is throwing this error!

Apologies if I sound naive, but I've not worked on ASP.Net for some time so not sure if there have been changes to the way newer versions wire-up events.

Anyway, my question is where is the wire-up for the cancel button to this event handler? As per your code you are creating the button at runtime, so you need to assign the event handler at runtime. Try assigning an event handler for this button.

If you use javascript the screenshot would only be available on the client machine and not on the server. I believe CopyFromScreen is the way to go.

Post your code so that we can see what is throwing the invalid handle error...

Where do you want to place the screen shot? on the client machine?

I assume you are getting the error when you access the e.RowIndex property? Are you able to pinpoint when this error occurs? May be it only occurs when clicking on the row header?

If you are not able to pin point / reproduce the error I would suggest you mask it by having a try...catch block around the code and doing nothing on the index out of range exception.

BTW, When you have buttons on the gridview to initiate this, why not use command click event rather than the cell click event?

I assume you just need to check the 8L+ records only once and you probably need to do the same thing for all records that are inserted newly when they are created?

Create a SSIS package to do the bulk operation and have a trigger and a stored procedure to do the subsequent checks.

why do you want to duplicate data between two tables? Is this duplication at the database level or only in the application level? if you just wish to duplicate the data try the clone method on the datatable object.

And your source datatable is empty either because you have not filled it yet or the orignial data source to your datatable is empty.

Please be more clear. Do you wish to crop the image or reduce the DPI? Do you want to do this when uploading the image or displaying it?

Do you mean when the server event is complete?

Why do you want to write something onto your server file system from a web application?? This is very dangerous and can lead to breakins on your server...

BTW, you do know that this piece of code would write to the server, right???

First off, what is the limitation to using a data adapter???
Next, Why do you assign a value form a query to a variable, when APF_PL_ID can have more than one APF_FRIENT_ID associated with it???

I don't get it... One product can have only one unit cost right?? Then why do you wish to execute multiple queries for the same product id???

Why not have a datapoint with "0" as the data???

Why do you need a custom control?? Why can't you have a normal page do this?? What pop-up are you referring to normal or ajax pop-up?

Why do you have so many tables in a single Template column? If you just wish to bind a checkbox and couple of images, use the bound columns to achive your requirement.

Can you elaborate your query and can you post your entire method, masking the "sensitive" text??

Why do you need to display your Emp id in a gridview? What else is to be displayed along with the Emp id? Why would you want to allow the user to edit employee id???

"document.getelementbyid" is how you access any control from javascript. When I said have a hidden text box to hold the value from javascript, this is exactly what I meant, i.e. you would access the hidden control say hdnText1 using "document.getelementbyid('hdnText1').value = varValue" and access the hdnText1 from the action code on the server side.

Apart from the solution below the code that you have posted contains a lot of unwnated lines of code and bad coding practices, I've pointed a few below -
1. When using data adapter, don't open the connection. Just provide the connection object. data adapter would take care of opening/closing the connection.
2. Check the status of the connection before attempting to close it.
3. Don't close the connection inside the try block. Do it in Finally block.

Just wanted to help.

The question isn't clear. Can you give more details?

BTW, I don't seem to find you having 2 forms, all I can see is Form2 and its instance form1 in the given code snippet.

Is "bobj" an object that you are using to load data for your reports?? Check if the data stream is working as expected.

BTW, please provide more details and correct the title to make it more relavent.

What is the purpose of the dropdown list? Is it doing a postback or is it clearing the contents using client script?
