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?
View 5 RepliesIm making a site in Visual Studio using vb and I have a variable in page_load but need its value in the event handler of a button for passing on session.
View 5 RepliesI 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?
Say you've got a form, Form1, and you're in the Paint event. Is there a way to test to see if, say, the Resize event is occurring from within the Paint event?

View 2 Repliesi have line like this 1.0 30 Blue (2 17.00 54.0) [2 16.03 52.0] 55611 30275 58571 23514 so i want to check after the Value Blue is that "(" or "[" in side my radio button checked change event.
in RadioButton1_CheckedChanged if the value is "( " the message box should come out and say "The file is already in PPin to Probe pattern" else if the value is "[" then there will be nothing to display.
this is my code Private Sub RadioButton1_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadioButton1.CheckedChanged Dim FileContents() As String = IO.File.ReadAllLines("C:\match1.txt")

Reading about VB .NET I found out that now it is possible to handle more than one control with the same event handler. What I want is to specify what my Radio buttons will have to do, using a single sub instead of using a sub for each of them. However I am still far from achieving that. I am using something like that:
Private Sub ForAllRadioButtons_CheckedChanged_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadioButton1.CheckedChanged, RadioButton2.CheckedChanged, RadioButton3.CheckedChanged
If sender.name = RadioButton1 Then
Code 1 ...
ElseIf sender.name = RadioButton2 Then
Code 2 ...
ElseIf sender.name = RadioButton3 Then
Code 3 ...
End If
End Sub
However, I get an error message which says :
Operator '=' is not defined for types 'Object' and 'System.Windows.Forms.RadioButton'.
I bet 100 $ that it's something that I don't do it right . Unfortunately I can't get that money. Would it be the same if use the Click event instead of the CheckedChanged ?
I have a windows form application built with Visual Studio 2008. When a use clicks a command button which does some action, I use SelectNextControl to automatically move to the next control in the tab order once the action is completed.
This seems to work very well, however, I have recently discovered that if the next control in the tab order is a radio button, the call to SelectNextControl does not simply make the radio button the active control... it also causes the click event to fire. When I use the tab key to move past the command button (rather than clicking on it which will result in a call to SelectNextControl), the radio button gets focus as expected and the click event is not raised (as expected). I don't know if this is a bug in selectnextcontrol or the radio button control.
Has anyone else seen/solved this problem? Another forum post discussed a problem where the radio button was automatically checked when a form was first displayed and the radio button was the first control on the form. Seems to be a very similar problem. That post was from 2008.

I have a series of radio buttons in a Group Box on my main form. When I run the program, the first step is Sub New and the InitializeComponent() procedure.
It then immediately goes to the first radio button CheckedChanged event. This even currently contains some programming to access information from a database table. However, the program hasn't even gone through the process of opening the database and logging in. This doesn't happen until after my frmMain.Load event. However, this happens after the CheckedChanged event for some reason. So now that I have included the data requirement, I am getting errors because the reader is opening before the connection opens. I know I can set up a Try....Catch....End Try to avoid a user error, but ...I thought the form would have to load before anything about the controls happens and then since I haven't clicked anything, I am not sure why the event is triggering.
I have one radio button and one listbox .i want code for display listbox depends on the radio button check true and false.

I'm curious if there is a "check all" kind of thing for a tablelayoutpanel? To explain, say I have TableLayoutPanel1 with 6 radio buttons and I'm doing an error check to make sure that at least one radio button has been selected during a click event. Do I have to do If / and with all 6 radio buttons? Or is there something like "If TableLayoutPanel1.checked(obviously not this) = false then".

View 2 RepliesI have a problem with running code in the right order. What I am trying to do is updating a session state variable when I press a button. When I run my code it always runs the event handler for the button after my page_load function.The reason why I need to run it after page_load is that, thatI add a line to the textList. Which the loadGui() should add to a table. The table has a remove button for all lines so the loadGui() function can not be added later becuase then the event handler of the remove buttons wont work.
User press the add button which add a row in the TempResponse Session(TempResponse) gets updated loadGui() runs and includes the newly added row

In my project I would like to call an exe so that exe pop up will come with a Login Screen with 2 buttons Login and Cancel.In those 2 buttons, login button is focussed default. Now my application should invoke the Login button automatically. Means there won't be Pressing ENTER KEY or Mouse Button Etc. Just after the Login Screen, there is a 2nd Screen that has 5 different Radio buttons, the 1st Radio button is always the default. So I also want to click this radio button automatically without using the keyboard or the mouse. y intention is that, the application should do that automatically.
I have tried with getting the handle of the focused Button by GetFocus method and tried to send that handle to the application by SendMessage and PostMessage. But it's not working.So can any body give some suggestion regarding this?
User will use a button1.click to open a filedialog to locate the file they needed. after which, the name of the file will appear on a textbox. Button2 is an OK button to write the filename into a txt file. Button2.click will work with the 3 radio buttons - meaning when Radio Button 1 is true and Button2.click is clicked, the filename will be saved asFile1.txt.if Radio Button 2 is true and Button2.click is clicked, the filename will be saved as File2.txt. Likewise to Radio Button 3

In VB6, I would have set up a control array and ran the routine when the array was clicked....but I am struggling with .net here, since there appears to not be control arrays at design time.
Is there 1 even I can use, or do I have to go into each radio button and code the individual event?
