Forms Data Controls :: Check Value Of Gridview Then Make Decision On Value?

Jan 20, 2011

I have been searching the net for four hours now and am coming up empty.What I am trying to do is to check and see if a value exsits in a column of a gridview and if it does not then do something. Basically I have a gridview that gets populated when a value in a dropdownlist is selected. This works fine. I get the information for the gridview by binding it to a SQLDataSource that returns two columns in a table from my SQL Server. The gridview only has two columns and one row as I am checking it from the dropdownlist. The second boundfield column is called Manufacturing Fee and it is a Money Type in SQL Server. I want to check if there is any value or if it ISNULL. If it is NULL or empty or less than 1 (any if these will work) then I am going to hide a button on the page so the user cannot do anything until this value gets assigned. (I know how to create this logic).I do not know how to get a value from the GridView as I am not selecting anything so I cannot use the SelectedIndexChange event or ONClick event.

Forms Data Controls :: Allow Only One Check Box To Be Checked In The GridView?

Nov 16, 2010

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...

Forms Data Controls :: Check If A GridView Exists?

Dec 9, 2010

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.

Forms Data Controls :: Gridview Check Box And Parse()?

Oct 5, 2010

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.
