Firing OnCheckedChanged Event With ASP:RadioButton
May 2, 2012
I have the following RadioButtons:
<asp:RadioButton id="rdoStandard" runat="server" Checked="true" GroupName="delivery" OnCheckedChanged="Check_Clicked" />
<asp:RadioButton ID="rdoExpress" runat="server" GroupName="delivery"
[Code].....
I have tried the above but also tried different ways, such as a click method for each of the RadioButtons and I never hit the Check_Clicked method.
I do not want to AutoPostBack, and cannot see why you would want to if you were firing an event?

I have two radio button on my asp.net page, with AutoPostBack = True When I click on either of those, they each set a flag SaveData=False However, when I click on them, the page_load event occurs first, so the page_load event saves the data, then the radiobutton_OnCheckedChanged event is triggered. How can I trigger the OnCheckedChanged before the page_load event?

I am using a monthcalendar inside of a panel. when the user changes the "showweeknumbers" of the calendar I need to move some label to the right of the calendar, but I also need to resize the panel. The problem comes into play when the user hides the weeknumbers, the monthcalendar resize event fires and the labels move, but the panel resize causes the month calendar to fire the resize event again, making the labels all out of wack...

I've been looking for a solution to this for several hours now and cannot find a solution.
The Scenario:I have a masterpage baseclass (called basemaster)All of my master pages inherit from basemaster
basemaster defines an event 'Public Event HandleClickEvent As EventHandler'I have a masterpage named master1
master1 defines an event handler 'Public Shadows Event HandleClickEvent As EventHandler'master1 has a user control named usr1 usr1 has a button that raises event ButtonClicked when clicked I have a page (thePage) that uses master1 thePage has a button click event handler that it registers like so: 'AddHandler Master.HandleClickEvent, AddressOf HandleTheClick' master1 has code something like:
Protected Sub Usr1_ButtonClicked(ByVal sender As Object, ByVal e As System.EventArgs) Handles Usr1.ButtonClicked RaiseEvent HandleClickEvent(sender, e) End Sub when thePage loads I see it register the handler on master1 when the button is clicked, Usr1_ButtonClicked is fired and I step through the RaiseEvent but HandleClickEvent on thePage is never reached.

And when you double click the same button, it blanks everything except the selected image. However the DoubleClick event doesnt seem to be working at all.

I've bound a bindingsource to a datagridview and each time i move the cursor on the datagridview to a different row, the positionChanged does not fire. This event handles other bindingsource too and I hv no problems with other datagridviews.
Im couldnt work out the behaviour for this particular datagridview.

I am running VS 2008 and building my app on a Windows 7 box. The main form/window has a KeyDown event handler as follows in it:
Private Sub Form1_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles MyBase.KeyDown
MsgBox("control = " + e.Control.ToString + ", shift = " + e.Shift.ToString + ", e.Keycode = " + e.KeyCode.ToString)
When I build it and run it within VS it seems to run fine. The messagebox appears with the state of the control and shift keys along with the key code of the key I pressed. However, if I take the executable and run it on an XP box (both using .Net Runtime 3.5) as soon as the main form opens, the messagebox appears. Basically the "KeyDown" event seems to be firing without any keys being pressed. The messagebox comes back with: "control = False, shift = False, e.Keycode = None".
How is this possible? How can the keyDown event be fired when no keys have been pressed (as is confirmed by the output contained in the messagebox?) how I can diagnose this on the XP box since it does not have Visual Studio on it?Update I tried creating a brand new project where there is only "form1" and the only code behind this is the keyDown event handler. It just opens a blank window and pops up the message box if a key is pressed. It worked as expected on the Win 7 box but when I moved the executable to the XP box, it immediately popped open the messagebox without pressing a key.

I have a user control on which the button click event stopped firing even if I add a new button. It can be noted I'm using Telerik RadControls: RadButton specifically.
There's nothing special I'm doing to reference the elements:

</telerik:RadButton>

Private Sub dgvEquipTran_DefaultValuesNeeded(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewRowEventArgs) Handles dgvEquipTran.DefaultValuesNeeded
e.Row.Cells("ID").Value = Me.cbxID.Text
e.Row.Cells("Rate").Value = 12

I've got the above event setup. However after select and delete the last row of a one row datagridview, the above event doesn't fire. Even when the current selected row is the new row (one with *). I have to click away, on the next tab and back again before it is fired and populated the new row with the values.

I used a timer in my user control now when Timer_Tick event is fired I want to raise an event like Ticked. I created:
public delegate sub myDel()
public event myevnt as myDel
in Timer.Tick
I used raiseEvent myevnt. I also raised the event from a button click. This event is handled in a windows form where the control is used, My problem is event is firing when the button is clicked but not firing from the timer.tick. Is there any problem from Timer.Tick.

I have a tabbed container, each tab has the same controls but for a different target. I am using a timer to control when to fire each event from the 5 different tabbed controls, my problem is this. The event only fires when the focus is on that specific tab. So when an event on tab2 should fire, if i am looking at tab1 then tab2 event does not fire.

I am using jQuery confirmation box within my listView and the confirmation box displayed with the user clicks delete. The problem that I am faced with, is that when the user clicks OK it, the lvAlbums_ItemDeleting event is not fired.
Below is the .aspx code:
<link href="jQuery/jquery-ui.css" rel="stylesheet" type="text/css" />
<link href="jQuery/jquery-ui-1.7.2.custom.css" rel="stylesheet" type="text/css" />
<script src="https://www.google.com/jsapi?key=" type="text/javascript"></script>
[Code].....
I have spent days looking at different jQuery confirmation box examples but this is the best I can do. Ideally I would want to be use [URL] within gridviews, dataViews and ListViews but can't find examples which exactly provide steps to follow.

I already have KeyPreview set to true in the form properties I'm working on a small program, and I'm having a problem where it seems that some of the controls on it inside groupboxes are not triggering the KeyDown event on my form when I press and release any arrow key, just the KeyUp event. Specifically, I've enabled KeyPreview on the form, and set breakpoints on e.SuppressKeyPress = True in both subroutines, and only the one for frmMain_KeyUp hits the breakpoint.
I added in the two GroupBox events hoping that might mitigate the issue, but no such luck. However, I have a custom control on the form that is specifically coded to ignore these keypresses, and the code works as expected on it.
Private Sub frmMain_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown, GroupBox1.KeyDown, GroupBox2.KeyDown
e.SuppressKeyPress = True
Select Case e.KeyCode
[code]....
The code in the user control that "ignores" keypresses is as such:
Private Sub TileDropDown_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
If e.KeyValue = 40 OrElse e.KeyValue = 38 OrElse e.KeyValue = 39 OrElse e.KeyValue = 37 Then
e.SuppressKeyPress = True
End If
End Sub

Using VS 2005 I've created a project with some form on it. Each of the forms are fairly similar in structure and I have copied the contents of one form to another form etc. I have code the loads the data into the ListView on each form and that works fine but when I put a Click event on the ListView, it doesn't fire. I created a new project to do some testing and put some items in the ListView and the Click Event fires when I expect it. What am I overlooking? The code for the Form is included below: it loads the data fine and I can select a line in the ListView but as previously stated, the Click event just won't fire!
Private Sub frmViewRequests_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

Is there a way to prevent the SelectionChanged event from firing when adding rows to a DGV programatically? I am adding rows in a loop & the SelectionChanged event fires twice, which is causing me problems. I only want it to fire when the user clicks on a row.

I'm using a datagridview in vb.net 2008 that is bound to a bindingsource.In the form load event, I have tableadapter.fill method to load the data.When the fill method is executed, the rowsadded event for the grid also fires.However, the event doesn't fire for all rows returned from the fill method.I've checked the bindingsource.count property to verify the number of records.The correct number of rows are displayed in the grid, but the event doesn't fire for all the rows.For example, there may be 4 rows displayed in the grid, but the rowsadded event only fires 2 times.There are several calculated columns in the grid, but the columns are only calculated for thenumber of rows that equal the number of times the rowsadded event is fired.The other rows are empty for the calculated columns.Does the rowsadded event always fire for each row?
