Asp.net - RadGrid Doesn't Update After Postback
Oct 24, 2011
I'm doing a form to add/edit/delete values from a data catalog. everything goes fine but the Radgrid doesn't update after Submit Button is pressed in the edit/new dialog. i did it before in a more complex form but i can't figure exactly what's wrong.
in the update the data where the new data will be overwritten dissapears after postback. (i have a way to solve this)
mnlib is a library of my authorship to deal with common tasks i know that queries with strings like {$database_name} is not a standart practice, and probably is not recomended, but i have to deal with it . i'm doing almost everything programatically some of the code is ommited because character limit in post Updated: Reduced code, i'm afraid if keep reducing code, i will eventually delete something important to the iusse

I have inherited an application that uses telerik controls. This is my first time to work with it and I'm a little confused.I have a RadComboBox that has its values hard coded. When the user selects an item, a RadGrid is refreshed to show the records that correlate with the item the user selects from this combo box. This all works great.I'm trying to create link buttons, so that when the user clicks on one, the RadComboBox value is changed to whatever value I set it to in the codebeind page and the RadGrid is refreshed to show the appropriate records.I can set the value of the RadComboBox, and see what value it has when debugging, but the RadComboBox in the browser does not reflect the change and the RadGrid is not refreshed when I programatically execute the event handler for it.

I've run into a problem that I'm at a loss to understand and/or work around. I'm working on a settings page that updates an XML file. The page has an XmlDataSource with a transform file (to filter and sort the values) and a DataList that is populated from the XmlDataSource. A user can enter a new group name into a text box and click a button to submit the form. When this happens, the new value is successfully added to the XML file.

I am using an update panel and when I click a button it will update all the panels. updapanel1.update() is very simple, but my data is not updating unless I hit the button twice. My gridviews shows data for a selected user, and then all the grids reflect that users data. works fine all the update panels work for the gridviews. Now for somereason when i try to do a row count and update the panel with the summary, it does not work, i get either the previous users summary or if i hit update again for the same user i get the correct data.

I have a gridview that is set to a sql datasource, it is generating the columns automatically. If I add a column to the table it is referencing, it will draw that column and display it, but it does not update the insert/update commands to include the new column. Is there any way have it rebuild those commands automatically?

Public Sub UpdateStaff(ByVal sr As StaffRecord)
Dim oldSr As StaffRecord
Dim q = From staff In db.StaffRecords Where staff.Employee_Number = sr.Employee_Number Select staff
oldSr = q.First
oldSr.Address_Line1 = sr.Address_Line1
[Code]...
The helper function I have written seems to do everything I want apart from update the db. Stepping through the code, the oldSr is updated by the new sr parameter but no update on submit changes.

I have a button inside of a gridview's template field. Onclick i want to the button to open up a modal popup while force updating the updatepanel and formview inside the modal popup because the formview's datasource depends on a hidden field in which i am setting after click also.

Whenever I build my VB.Net project, the Assembly version does not automatically update as it is supposed to with the * in the third box in the Assembly Information. The only way I have found to (sometimes - it doesn't always work) get the version number to update is to Clean the Project, remove the *, Rebuild, reClean, put the * back in, and Rebuild again. What could be causing this issue to happen?
I should note that my coworker reports no such issue on his machine when Building the same Project; also, I must admit to some confusion on my part as to how this behavior is even possible, given that the error persists even if I remove every possible intermediate file I can think of that could possibly even be carrying the old version number, so how does it even know the old version number?

Now it updates when I press the update button and then it displays the data like it has updated the database, but when I close the program and run it. It displays the data as not updated WHY DOESN'T THE DATABASE UPDATE?Same with the Add and delete commands, I've almost finished my program but there's always a problem :...
Dim StudentID As Integer = Me.Lst.SelectedValue
Dim con As New SqlConnection("Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|StudentTeacherDB.mdf;;Integrated Security=SSPI")

I've come across some strange behavior. I have a control that binds to a property like so:
<HyperlinkButton x:Name="ProjectBeheerLink"
Visibility="{Binding IsBeheerder, Converter={StaticResource VisibilityConverter}}"/>
In my viewmodel I have the property implemented like this:
Public ReadOnly Property IsBeheerder As Boolean
Get
Return iwtApp.AllMyFunctieRollen.Any(Function(x) x.Rol.Equals(Constants.RoleBeheerder))
End Get
End Property
Then when I raise my PropertyChanged event in my callback method
Private Sub GetMyPersonCompleted(ByVal lo As LoadOperation(Of FunctieRol))
'Init FunctieRollen ect. ...
RaisePropertyChanged(Function() Me.IsBeheerder)
End Sub
my binding does not update. However! If I implement a backend field like this:
_isBeheerder = iwtApp.AllMyFunctieRollen.Any(Function(x) x.Rol.Equals(Constants.RoleBeheerder))
RaisePropertyChanged(Function() Me.IsBeheerder)
And change my property like this:
Public ReadOnly Property IsBeheerder As Boolean
Get
Return _isBeheerder
End Get
End Property
Everything works fine...

I have an installer, and it installs some native dll's along with the program.The dll's are in a separate folder, which I added to the path environment variable.That was done successfully, and the variable shows up in path if I check the windows system settings.
However, if I start the command line program/service, it says dll's not found...I check the environment variable path with the set command, and my folder is not in there.If I do
SET path = %path%;my/folder/here/
And start my program after that, then it works.According to this MS KB article this is because the computer would need to be restarted.unless I do
SendMessageTimeout(HWND_BROADCAST, WM_SETTINGCHANGE, 0, (LPARAM) "Environment", SMTO_ABORTIFHUNG, 5000, &dwReturnValue);
Now I did just that, using the below code, but the error message persists. My folder in %path% is correctly spelled, I checked that.

I have a form called 'Bookmarks' that loads a bookmark file that contains a single word on one line. I have put buttons on the form for sorting this list, deleting items and changing the character case to lowercase, uppercase or Sentence Case.Now, deleting and sorting the list works fine, but when I try to change character cases,nothing happens. I started the debugger and found that my case changing code does work, but the listbox doesn't seem to update it's contents.I tried listbox.Update() and listbox.Refresh() but that didn't work either.
Here's my code for 'Set Case':
Private Sub setCase_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles setCase.Click
If bookCase = "default" Then Exit Sub
If bookCase = "lower" Then

So, I'm working on a simple game in Visual Basic, and I have 2 labels. One named "pointsLbl" and one named "pointsleftLbl":
pointsLbl.Text = "Points: " & points
pointsleftLbl.Text = "Points left: " & pointsleft I also have two integers, one named "points" and one named "pointsleft". The problem I'm having is that when the point boost button is pressed, the labels don't update and also don't show the new points and new points left. Private Sub boostBtn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles boostBtn.Click

I am using Visual studio 2008. I didn't see a place to post questions about this . I am creating a mobile application, at run time the executable itself is not updating to show the changes from source code i have written. I feel there must be a setting or something in visual studio .

I have an editable datagridview that's been databound with dataadapter and datatable, and a normal button on a form. When i edit the dgv's cells and click the save button it fires the datagridview_cellvalidating event and if the cell validation is correct it updates and saves the current record to the datasource. Also, before save it commits change in any cell under editing. But when I use a toolstripbutton to do the same work, though it saves the dgv records but doesn't update the current change i.e. it saves the old records that are being fetched when the dgv was populated first during form load. Also, clicking the toolstripbutton doesn't fire datagridview_cellvalidating, datagridview_rowvalidating etc events. What it seems to be is it's not committing the change in any cell under editing. [Code]
Why isn't it happening and how can I make it work? how can I fire datagridview_ cellvalidating, datagridview_rowvalidating and other events; and commit cell value change by clicking toolstripbutton.

It seems like a lot of people are having trouble with this piece of the control toolkit.I've looked for a few days on the internet for an answer and haven't been able to find one. Best solution I've seen so far is "write your own reordering procedure" which I don't want to do.
<asp:ScriptManager ID="smgrJobBidding" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="uPanelReorderList" runat="server"

And it publishes to the ftp location.Then I get the setup file from that location and run it on my pc. It loads my app fine. then I build and publish again.

So i have that code in my xaml and the button gets filed with a list of string. Depending on what the users chooses on previous Usercontrol that item will be filed with differents items. The problem is if the user select one option at the first run the button will be filled correctly but if the user go back and select the other option the control doenst update and shows the same as before.. My english is not the best but i think i could made me understand! PS: the bindind on Button is to a readOnly property so i cant define it to Mode="TwoWay".. i took a look on the debug and the property ExportFormat gets updates with the new items but the usercontrol still displays the first option!!
