On my .aspx page i want to be able to show and hide certain panels depending on user selections (radiobuttonlists).
For example in my aspx page i have;
<form id="form1" runat="server">
<asp:RadioButtonList ID="RadioButtonList1" runat="server" AutoPostBack="True">
<asp:ListItem>1</asp:ListItem>
[Code].....
How can i make a control required to put input depending on the radiobuttonlist selection?
Let me try to clarify a bit more. I got 2 radiobuttons, if one gets selected, nothing else has to be done.
But if the otherone gets selected, a textfield must have some input too.
I have a form that has two views. These views are controlled by radio buttons on top of the form.
Here is the program:
Notice how the Radio button for Number Converter is selected.
Here is what it looks like when you select the Text Converter radio button:
That isn't right. I have it set to hide the panel containing the number converter and show the one containing the text converter when you click that one. It hides the number converter but doesn't show the text converter.
Here is a picture of the text converter panel:
Here is the relevant code:
Private Sub frmCalculator_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
rdoNumberConverter.Checked = True
End Sub

Currently my program randomly removes words from a set of text and inserts textboxes below the text. The user can then enter his/her answers in the new textboxes. What I would like to do is set the program so the user can have two choices one being Easy and other being Advanced. Then when the user hits either button it brings up everything that is currently on the form. I'd prefer to do this without having to use MDI forms. I've had a hard time using the MDI forms and therefore would like to avoid using them. They way I was thinking this could work is all objects would remain invisible except for the 2 buttons and then when you hit one of them they disappear and everything else appears.

I have a timer that on tick checks to see the value of a an element in an array using a counter on another form as well. The picture boxes are initially set to false for visible and they should become true when the timer ticks and the element is equal to 1. I know that the pictureboxes have a valid picture in them because if I initialize them as TRUE first, it shows up properly. I also know that I am entering the IF statement because I can put a simple MsgBox with any string in the IF statement and it will display when the requirements are set. But yet the pictureboxes still do not change.

View 3 RepliesI seem to be having a problem binding the visibility property of a textbox to a database value using the advanced binding property.
I found this article (BUG: Inconsistent behavior when you bind the Visible property of a Windows Form control to a Boolean field) stating there is a bug in some older versions of the .net framework.
Does anyone know if this has been fixed in 4.0?
I have set the Visibility property of the main window to Hidden and added the following in Window_Loaded:
private void Window_Loaded(object sender, RoutedEventArgs e){
this.Visibility = System.Windows.Visibility.Visible;
}
But it doesn't show up the Window.

View 2 RepliesJust wondering if someone can at least point out where I'm going wrong here. I've already got the code to populate the listbox by a button click from the user and am just trying to figure out how exactly to alter the text of a label based on what the user selects in the listbox. From what I have the Label will display the case else selection but nothing else despite my best efforts to get it to change. Here is what I've tried. I realize it is very trivial, but I am only a beginner to programming.

My issue is that I am trying to take the value of the radio button chosen and turn it into a font color. Therein lies my problem. I see that it cannot be a string, but when I turn it into an object, I get an error.

I have a panel inside a formview that is supposed to become visible when a checkbox (also inside the formview) is checked. I am able to access the controls, but I'm not sure how to actually make it work. This is my codebehind so far, I know it's not right, but it gives a basic idea of what I'm trying to do.[code]

I have a few panels that contain the controls, how can I check them all at once rather than use that code above and just change the panel number each time? It'll get pretty messy if I have to keep pasting all that code and just changing one number.
I have just realised that ComboBoxes don't have a Change event. I have a combobox filled with a few items, eg. Bakery, Deli, Fruit & Veg, etc. Choose one of these items, all the related items show in the dgv. However, when I blank the text in the Combobox (press Delete key whilst Combobox has the focus), what event fires so I can blank the dgv? The combobox does not contain a Blank item. Even if it does, the Blank item only fires the ComboBox1_SelectedIndexChanged when the user scrolls down to, or clicks on, the blank value.
I want to clear the dgv when the user blanks the combobox without necessarily changing the selection index.
When i am assigning text in to textbox that time the selection start property is zero so the cursor(caret) is moving to first location of the textbox.
Code Sample
Consider that the textbox already have text like 'Hello Developers'
Dim CurPosition As Integer = TextBox1.SelectionStart
'CurPosition=11 (i.e) SelectionStart is 11 (cursor position)'
[Code]....
so when i am executing this code the cursor move up and down
I make a panel visible that has a tab control on it.
The panel becomes visible - I can see all three tab pages.
But the contents of the tab page is blank - until I actually click a tab heading.
[URL]..I cannot seem to get a regular panel control to anchor Left/Top/Right while place in a FlowLayoutPanel which is docked to a Form. It defaults to a Left/Top position and I cannot seem to get it to anchor to the Right as well either by code or by manual input in the Properties window.
Does this imply that there is an issue with my VS Studio 2008 Express?
Why does a Panel control have a Font property? What does it affect? Any controls added to the panel will have their own Font property that controls their appearance, so I don't see the point of the panel control having a Font property, especially since it has no text property.

View 4 RepliesI use drag'n'drop from a datagridview to a panel. The panel holds an array of objects (think rows) so that the items from the datagridview can be dragged to the different objects. I use the y-index from the top of the panel to define what object the item is dragged onto.This works great as long as the object is visible from the start. However, if I scroll down to an object and then drag the item from the dgv, it gets released on the wrong object, as the y-index doesn't take into account the number of pixels I scrolled down. So, what I need is (if it exists) the scroll offset property for the panel, i.e., the number of pixels that I scrolled down. (Then I can add this offset integer to the y coordinate on which the user drops his/her object.)
