I have a grid view with two columns...one column has a no. like (123) and a check box....which user can checked or unchecked......all I need to do is that I need to disable the man handling of that check box......rather I would like to see a seperate grid view with the same no. of rows as of the first and in this gridview I may allow to type in or scan the no. and if this scanned or typed number matches any no. in the first gridview number then the corresponding check box should be checked/unchecked.

I have problem with gridview sorting. I am using online example to sort a grid view. see the link [URL] but I always got an error "The gridview fired sorting event without handle" on this statement "helper.ApplyGroupSort();"
<table width="100%">

I have a gridview that returns several records for the same user and each record has a column with a check box. I need to allow the user to choose only one to check. Also one check box is always supposed to be checked. What is the best way to do it? I was thinking of writing a stored procedure that checks if only one is checked, and then returns true or false. I think there is a more efficient way to do it...

I have a page with a simple textbox, when an OrderNo is entered in te textbox the page is populated with 2 or 3 gridviews depending if the order has items reserved or on back order.
GridView1 has data about the order, like status, payment details.
GridView2 has data about orderitems, each row displays an item from the order with stock and order quantities
GridView3 has data about backorders, each row displays an item from the order with quantity reserved and quantity on back order. As is no data for GridView3 if order is not on backorder I thought that I can enclose my code inside an if block
if GridView3 isnot nothing then
'getting some data from the cells in GridView3
endif
but the code still executes.

Documentation for using a checkbox with a gridview has the following statement:Because a check box can display only a selected or an unselected state, a CheckBoxField object can be bound only to a field with a Boolean data type or a string that can be parsed byParse.No example has yet been found to explain how using Parse to control the value of theis done. Interestingly enough I can find a fine example for the unlikely scenario of embedding a bulleted list in a grid cell.

I have this scenario where i want to select multiple customers at a time and add them to a group/role. to do this i thought of using a gridView and listed them all with sqlDatasource and enabled 'selection' for gridview. but by default grid view is allowing only one selection at a time. so is there a way i can insert a new column of check boxes and some how read the gridview to know which checkboxes are selected? if you know a better approach than a gridview or check box please suggest me. i am not very familiar with asp.net so
