I know my question reads a bit like that 'how much wood can a woodchuck chuck' line, excuse that... I have a repeater with checkboxes. There are numerous rows in this repeater - I never know how many - I want only one checkbox checked at any time. If the user changes the checked checkbox, any pre-existing checks are unchecked therefore maintaining a single checked checkbox.
I am using VB, but comfortable to port any C#. I want to use JQuery. I have been looking on Google, but only ever seem to find ALL checked, ALL unchecked systems.
I want to be able to only set one record in my tables as a default value. So when I check the checkboxcolumn of one row in my datagridview all the other checboxes in the other rows must be set to false. How can I do this?

Question 1: This loop works when the Panel only consists of CheckBoxes. But I would also like to have som TextBoxes in the Panel. When i add a TextBox to the Panel I get the error message:

I have a form that uses 28 checkboxes (checkBox1 ~ checkBox28), 28 labels (label1 ~ label28), and 28 textboxes (textBox1 ~ textBox28). These items need to be visible/invisible depending on the mode of the program (there are 5 modes). I could specify each item individually with visibility, but that requires a whole lotta code! Is there a way I can loop through 28 labels?

View 2 RepliesI have the following for each loop which loops through a registry key and reads all the values:
Dim returnValue As RegistryKey = Registry.LocalMachine.OpenSubKey("SOFTWAREMicrosoftWindowsCurrentVersionRun")
Dim keyname As String = "HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionRun"
Dim values() As String = returnValue.GetValueNames
[code].....
What I am trying to have been highlighted in bold.. Each time the loop executes and reads a value from the registry, I want the code to create a checkbox which has a unique name and text according to the value that was read... So the number of checkboxes will depend on number of values that is got from the registry...But this doesn't work. It only creates one text box and the text of the textbox is also incomplete...
I have a input form that has a number of check boxes on which relate the users enquiring courses. I need to create a loop of some sort that allows each checkbox to be checked it is selected. If so, output that within a message box. Thats it put simply anyway.
I have removed a lot of the code that is not related to this query but my code at the bottom is the message box that i wish to output all details in.[ocde]...
I thought I could use this, to loop through all checkboxes in a frame:
For Each cb As CheckBox In Me.frameSearch.Controls
cb.enabled = False
Next
But it walks through once, then it comes with error:
Unable to cast object of type 'System.Windows.Forms.Label' to type 'System.Windows.Forms.CheckBox'.
There are indeed labels within 'frameSearch', but I thought that the "For Each cb as Checkbox" would loop only through all checkboxes..? Following does work, but it seems a bit of waste of CPU time, since it will loop through all controls!
For Each cb As Control In Me.frameSearch.Controls
If TypeOf (cb) Is CheckBox Then
cb.Enabled = False
End If
Next
How to do this more effectively?
I'm doing an assignment for Uni and in my VB.NET form I have some checkboxes, I'm trying to loop through and clear them (I have a button which will clear the form). My problem is that there seems to be no property I can use to set the state of a checkbox when not explicitly telling VB which checkbox I want to use. for example, I can go
WineCheckBox.Checked = False
That will check the box, but I wand to DRY the code up a bit and not have to repeat this for each check box I have, this is what I was trying to do:
If TypeOf element Is CheckBox Then
element.Checked = False
End If
I've tried using element.CheckState and element.Checked and both times I get "Checked (or CheckState) is not a member of System.Windows.Forms.Control".
This is the whole block of code:
'clear the controls
For Each element As Control In Me.Controls
If TypeOf element Is TextBox Then

Suppose we got a form with some checkboxes. Each ckeckbox represents a method of the same class. Each method takes no arguments, returns no values. Is it possible using a delegate to loop through the checkboxes and run only the methods being checked?
View 4 RepliesMy application uses 12 checkboxes. Dependant on the status (checked or unchecked) different action are required. I can't seem to be able to structure a for next loop to do this.
View 7 RepliesI'm trying to loop through a column of checkboxes to see how many checked values there are in that column. The user has to have 2; no more, no less than 2, otherwise an error should show up.

I have several checkboxes in a groupbox on a vb 2008 express userform. I would like to check the checked status of each when clicking a command button and then write the checkboxes caption to be used in an email or print out. I've tried several methods and always end up with the same error "Invalid Cast Exception". I have read the help on msdn and still do not understand how to make it work. Here is the code I've been trying
Dim chk As CheckBox
Dim sb As New System.Text.StringBuilder
Dim names As String
For Each chk In gbInterior.Controls
[code]....
I have also tried the code below but cannot figure out how to check the status and print the checkbox caption.
Dim ctl As Control
For Each ctl In gbInterior.Controls
If TypeOf ctl Is CheckBox Then

I have a datagridview with checkboxes in the first column and I want to do a loop on saving the serialnumber(s) when the users decides to check a number of checkboxes Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
[Code]...
the problem with this code is that it only inserts the serial number of the LAST checked checkbox and the number of entries of it depends on the number of checked checkbox for example ... if I checked the rows with the serialnumber 123 and 55652341, first the row with the serial number 123 then second 55652341, only 55652341 appears in the database and it is entered twice(twice because two checkboxes are checked)
Makes the following statement about the code below:
**"The computer evaluates the loop condition in the Do...Loop statment to determine whether the loop instructions should be processed. In this case, the inputsales <> String.Empty condition compares the contenst of the input sales variable to the String.Empty value. As you know the String.Empty value represents a zero length, or empty, string if the inputsales variable is empty, the loop condition evaluates to True and the computer process the loop instructions. *If on the other hand the inputsales variable is not empty, the loop condition evaluates to false and the computer skips over the loop instructions.
Based on the code I think it is the opposite: ...that while the inputsales value is not empty it should evaluate to true and process the loop and if it is empty it should evaluate to false and skip the loop?
See below.
