i have a UP and DOWN buttons ouside a gridview and a checkbox inside the templated field .I will check the checkbox to sleect a row , after that if i click on UP button the checkbox above the selected checkbox should be selected.
same with when i click on DOWN button the checkbox below the selected checkbox should be selected.
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.
View 1 RepliesI have a gridview on my page. I have a checkbox in each row of this gridview. For each checkbox in the gridview, I'd like to update my table accordingly, but I don't want them to have to hit a submit button every time they check the checkbox. I want them to check all the boxes they need to and at the end, they should hit one submit button.

As you can see i have some bound fields and one template field called "txtValue" which is the only input in gridview. Now what i want is when user input the value it should check the FACEVALUE and see if the entered value is not above the FACEVALUE and then need to Input value - FACEVALUE and result should be displayed in REMAINING field which is also a template field as label control.
I have gridview wich bind with dynamic datatable.

im reading checkbox value which is checked on my gridview but as per my code is missing the 1st one which on top but i select from the middle then it is working fine here is link for gridviewhelper classes [URL] and im calling this code from gridviewhelper classes on page load event
Dim helper As New GridViewHelper(Me.GridView2)
helper.RegisterGroup("heading", True, True)
AddHandler helper.GroupHeader, AddressOf helper_GroupHeader
and here is my code
Dim sc As New StringCollection()
Dim id As String = String.Empty
For i As Integer = 0 To GridView2.Rows.Count - 1
'loop the GridView Rows
Dim cb As CheckBox = DirectCast(GridView2.Rows(i).Cells(2).FindControl("CheckBox2"), CheckBox)
'find the CheckBox
If cb IsNot Nothing Then
If cb.Checked Then
id = GridView2.Rows(i).Cells(1).Text
sc.Add(id)
MsgBox(id)
End If
End If

(select convert(varchar(8),itbl.PUNCHED_TIME, 114)+', '
from Trn_Capture_Data_New itbl
where itbl.EMP_CODE=tbl.emp_code and itbl.PUNCHED_DATE=tbl.punched_date and itbl.EMP_CODE='4'

Date,IN,OUT,IN,OUT
In punched time the first one should be IN and second OUT. A employee would have punched several time a day. Based on that I should take maximum punches and bring that of columns as IN and OUT in gridvew dynamically. How to achieve this?
I have 5 user controls in a web form. Data is being loaded into the user controls at the user control page load event. I have a single save button for the entire web form(the the top of the page). Each user control has update panel and consists of many web controls like textbox, dropdown,gridview and many other.
after the page has been rendered successfully to the user.
Considered that he has changed text in one user control ( in few textboxes,dropdowns , grid) and clicked on save button.
Now I should save only the changes user has made ( in 1 user control) instead of saving all the 5 user controls.
how can i achieve this?

View 1 RepliesI 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...

View 13 RepliesI 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.
View 4 RepliesI have loaded up a gridview object with data. I have turned on Edit on the grid. It lets me edit the data, but I also want to put some code to check for correct data in each field. I tried to assign a requiredfieldvalitor, comparevaliditor but they don't work. Is there an event I can capture to fire up some code before the grid sves my data?
