Forms Data Controls :: GridView Sorting, Paging And DataBinding / When Control Causes A Postback GridView Is No Longer Sorted?

Jan 10, 2011

I'm trying to extend the GridView control to enable sorting and paging for any situation.

When using my control I am fetching data from a database and filling a DataSet with it, then binding the GridView upon every page load. My first question would be, is this the correct approach?

To sort the GridView I am overriding the OnSorting method which stores the sort expression and direction in the ViewState, then creates a DataView and utalises the Sort method to sort the underlying data. It then sets the Data Source to this DataView and rebinds the GridView.

Paging is handled by OnPageIndexChanging which simply sets the PageIndex property and again rebinds the GridView.

My problem is; when any control causes a postback my GridView is no longer sorted, presumably because it is persistently rebound. If I don't rebind it then the GridView is empty on postback since the data isn't automatically stored in the ViewState. I have considered saving the data source in the ViewState but I would assume that this is bad practice for large amounts of data? - also DataViews are not seralisable.

The only solution I can think of currently is to override OnDataBound and sort the data every time. This results in a double sort when paging triggers a postback which seems inefficient. Code illustration of this below,


I'm looking for the cleanest 'best practice' solution as this is a learning exercise more than anything else.

Forms Data Controls :: Paging In Gridview Control 2.0, MySQL

Feb 20, 2010

I am a new user of ASP.NET 2.0 (VB.NET)
I am facing a problem related to GridView Control

I have a table <UsersDetail> with following structure in MySQL

userid | Numeric
Userlogin | Varchar(25)
Userpassword | Varchar(25)
Firstname | Varchar(50)
Lastname | Varchar(50)

I wrote a code to fetch data from this table :

Dim Con As New MySqlConnection
Dim Cmd As New MySqlCommand
Dim Adp As New MySqlDataAdapter
Dim DTable As DataTable
Con.ConnectionString = ConfigurationManager.ConnectionStrings("dbConString").ConnectionString
Cmd.CommandType = CommandType.StoredProcedure
Cmd.CommandText = "sp_FetchAllUsers"
Cmd.Connection = Con
Adp = New MySqlDataAdapter
Adp.SelectCommand = Cmd
DTable = New DataTable
GridView1.DataSource = DTable

Basically Gridview controls is used to display data in tabular format.
but due to requirement I changed its layout to columner in following manner

<asp:GridView ID="myGridView" runat="server" AutoGenerateColumns="false" AllowPaging="True" PageSize="3" Width="520px">
<asp:TemplateField HeaderText="User ID">
<asp:Label ID="Label3" Text='<%#Eval("userid") %>' runat="server"></asp:Label>
<asp:TemplateField HeaderText="User Login">
<asp:Label ID="Label4" Text='<%#Eval("Userlogin") %>' runat="server"></asp:Label>
<asp:TemplateField HeaderText="Pack Amount">
<asp:Label ID="Password" Text='<%#Eval("Userpassword") %>' runat="server"></asp:Label>
<asp:TemplateField HeaderText="For">
<asp:Label ID="First name" Text='<%#Eval("Firstname") %>' runat="server"></asp:Label>
<asp:TemplateField HeaderText="Validity">
<asp:Label ID="Last name" Text='<%#Eval("Lastname") %> Months' runat="server"></asp:Label>

Now come to the problem, i set the AllowPaging="True" and page size to 3 records/page but when click on paging links it displays the following error :

The GridView 'myGridView' fired event PageIndexChanging which wasn't handled.

An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Web.HttpException: The GridView 'myGridView' fired event PageIndexChanging which wasn't handled.

Forms Data Controls :: Using GridView With A User Control And Passing Object Into Control?

Jan 8, 2010

I would like to use the gridview paging feature and have built a gridview with a user control. The data source has lots of columns, so to make it easier I want to return a LIST<MyObject> and just pass <Myobject> into the user control rather than all the data elements. Not sure how I access the object of the data source to bind to the control. Assume it would be during ondatarowbound.

Also, my guess is there is a better way to do this than gridview. I'd take either solution that allows me to have easy paging and pass the complete object into the user control

Forms Data Controls :: Create And Persist A Dynamic Control Inside Of Each Gridview TableCell

Jan 25, 2011

I'm having difficulty trying to create and persist controls inside of a gridview during postbacks. I have an unbound Datagrid control which is created with x number of rows and y number of columns during the Page_Load event.


During the RowDataBound event of the GridView, I create a placeholder control and then I create a label and add the label to the placeholder


On the first page load when navigating to the page, the grid dispays perfectly and the labels are created with no issues and I can see the "1" in every single cell of the Gridview. I basically need the labels in the cells to store an ID when the cell is clicked (the click event works with no issues, wired it all up with javascript) and Since the Cells to not exist prior to "Building the matrix" method, How can I persist the Label controls inside of the tablecells between postbacks so I can assign and read values from them.

I've read a number of online posts from 4guys from rolla and they demonstrate how to persist a handful of controls dynamically created in a staticly defined PlaceHolder conrol outside of the complicated setup of the gridview and have failed at adapting them. The golden rule seems to be to 'recreate' the controls during Page_PreInit during the postback, but I can't seem to get it working.

Forms Data Controls :: Handling Events From A User Control Inside A GridView?

Jun 4, 2010

I have a user control called ucTriStateButton. It raises an event when it is clicked, called TriStateButtonClicked. If I put this user control on a page, it works fine. Here is the declaration on the .aspx page:


When the button is clicked the method tsbTest_TriStateButtonClicked executes correctly.

The problem is when I put the user control in template field of a GridView.


There is no way to hook the event handler to the control in Page_Load because I cannot get a reference to tsbMorning. So I did it in the RowDataBound event handler of the GridView, where I also do a bunch of other row-specific stuff. Although this builds and runs, the event is never actually subscribed to and so never gets fired.

So the question is - how can I handle an event from many instances of the same user control within a GridView? I am calling the same bit of code regardless of which user control is actually clicked. I only need to know that one was clicked.
