Forms Data Controls :: Gridview Not Refreshing After Databind?
Jun 26, 2010I'm working on a project where I have to create a page that displays the "health" of a system. I run a query and display the results in a gridview with a red or green icon next to it. This works fine when the page is first loaded. My problem is that I have a thread that runs a query every 30 minutes and rebinds the gridview but the gridview never refreshes even though the data has changed. How do I get the gridview to display the new results? The databound event never fires a second time even though I can clearly see that I have received new data. I assume I am missing something simple but I just don't know what. What am I doing wrong?

Forms Data Controls :: When To Call DataBind On GridView
Sep 2, 2010So I have a GridView and several events that can be triggered (such as filtering and inserting a new record) to manipulate the GridView. I want to make sure that I'm not calling DataBind on Page_Load, especially since I might have to call it again when certain events fire. Is there a way I can make it so I only have to call DataBind once on the GridView after Page_Load and anything else has fired? Like some event that will absolutely fire last where I can put my DataBind?
The reason I need to do this is because the DataSource for the GridView is set programmatically from a DataView when the page is loaded, so DataBind needs to run every time. Just, hopefully, not multiple times each time...

Forms Data Controls :: Position GridView After DataBind?
Mar 7, 2011I have a gridview positioning issue that may have been answered elsewhere, but I couldn't seem to find a similar post...
I have a webforms app containing a paged gridview (e.g., 200 records - 50 rows and 4 pages).
When the user clicks on a button in a specific row, another web page is launched to process that button click. When the user closes that page to return to the main gridview, the databind event is rerun and the page redisplays the gridview starting at the top. However, I want to have the previous position maintained (like an html bookmark), so that the grid will automatically be scrolled to the the previously clicked gridview page and item.
Setting attributes such as "MaintainScrollPositionOnPostback" do nothing in this case.
Forms Data Controls :: DataBind In A PostBack Event?
Oct 25, 2010 My data-binding problem is this: I have a user control that contains a DataList, withing the user control I have an array of objects that are binded to the data list. This works fine and the datalist displays exactly what I want. I have also set up an event that changes the background color of one of the controls on a click. So when the click event happens through a bubble event I change the controls backcolor and then try to call the DataList.DataBind(). This does not work when all the controls Page_Load happens my binded object from the Array is now null. All the examples I have found in code that seem to work have you recreating the data source before calling the DataBind function in the PostBackEvent asp.net step. I don't understand why this is or how I'm suppose to resolve my situation since my datasource in my user control can't easily be recreated. I hope I explained this well I have included a test program that sort of duplicates the issue I'm having. If you run this code you will not get the data list to display at all on a click event. But if you call the BindList function it will work correctly.

Forms Data Controls :: Datagrid Databind Is Splitting One Data Item Over Two Fields
Dec 8, 2010I am having an issue with a simple databind to a datagrid. What happens is that for some reason, the first character of the data going into the 4th column is getting placed at the end of the data in the third column; but only on the first row. Here is an example of what I mean:
Form ID
Employee No
Associate Name
Start Date
End Date
Form Status
1234
5000187
Stan Marsh1
1/16/2010
11/30/2010
Approved
1234

As you can see, in the first row of data, a "1" has been moved from the Start Date column to the Associate Name column. Because this is a databind I don't see how this is even possible. I'm just curious if this is a known issue or just some random fluke. Here is the relevant code:

Forms Data Controls :: GridView Control On Page Not Showing Current Data On Databind
Jan 29, 2010I have a page with a gridview control that shows files that have been uploaded to our site. The name of the uploaded files, who uploaded them, and if they have been downloaded, etc are stored in a table. The gridview is bound to the table through a sqlDataSource control. I have a button column in the gridview that downloads the file associated with a row when the button is clicked. All that works well. I have a check box column that shows checked if a file has been downloaded. When the download button is pressed.
the file downloads and then a short routine is run to update the downloaded field in the uploaded files table to set the downloaded field to true. This is done through a command string. All this works. Here is the question. After the update is run I do a databind on the gridview to update it. The databind is run in the PageLoad event is the page is a postback. This does not cause the current row to show downloaded =true (checked). If I refresh the page in the browser then it displays correctly.

Forms Data Controls :: Format Data Value Before Databind To Gridview?
Feb 8, 2010I need to display data returned from a sql query into a gridview. This is easy enough to accomplish by running the code below:
Dim command As New SqlCommand(sql, connection)
command.CommandType = CommandType.Text
connection.Open()
Dim da As New SqlDataAdapter(command)
Dim ds As New DataSet()
da.Fill(ds)
Me.grvDisplay.DataSource = ds
Me.grvDisplay.DataBind()
My issue is that for one of the columns, before it gets bound to the gridview, I need to format the value. Basically, it returns a value like 7.21. Each number represents something, so I need determine what this and display the worded value. I tried to do a datareader (see below) before the binding and store that value into a session variable and display that session variable into the gridview, but it just displayed the same value over and over.
Dim dr As SqlDataReader = command.ExecuteReader()
dr.Read()
Dim RT As String = ""
Dim VersionName As String = ""
Select Case Left(Replace(Mid(dr("Version"), 2), ".", ""), 1)
Case "1"
RT = "Pre-Release"
Case "2"
RT = "Final Release"
Case "3"
RT = "Interim Release"
End Select
Session("VersionName") = Left(dr("Version"), 1) & " Data Base " & RT & " " & Replace(Right(dr("Version"), 1), "0", "")
dr.Close()

Forms Data Controls :: How To Avoid Repeater Databind On ItemCommand
Apr 3, 2010I have a repeater which does quite expensive processing when it is populated. It gets the info from a web service which is itself a federated search service and will take 15 to 20 seconds to return results.
In each repeater item/alternatingitem, i have 3 imagebuttons doing some actions (saving in session some ID's, updating some custom collections...) , the problem is when clicking on one of the buttons, the repeater will trigger the command and then databind again, which takes quite some time to process again..
