View 1 RepliesI have a checkbox list which is filled with entries from my database on page load. I need to update an entry in my database when a item is checked and when an item is unchecked. Right now I am doing the following:
<asp:CheckBoxList id="check1" AutoPostBack="True" TextAlign="Right" OnSelectedIndexChanged="Check" runat="server">
</asp:CheckBoxList>
And the function:
Sub Check(ByVal sender As Object, ByVal e As EventArgs)
Dim sql As String
If check1.SelectedItem.Selected = True Then[code]....
The error is: "Object reference not set to an instance of an object." Is there a better way to check if a list item is checked or unchecked?
[Code] The code is to make when one checkbox being checked, other checkbox within the gridview will be unchecked. But this code did not work at all. Is it my event handler wrong or code problem?

I have a form that creates a row of checkboxes depending on the type of analysis the user wants to perform on the incoming file. I need to be able to determine if the checkbox is "checked" but I don't know how to do that when the controls are created at runtime.So right now I have a loop going through all the controls on the form and selecting the appropriate case: for instance chkbox1, combobox1, etc. Now I can access the values of the control by using Me.Controls.Item(chkbox1) but after that the only thing resemebling checked is .Text which wouldn't be accurate. how do you workaround the .Checked property of a checkbox when it is created at runtime?

What would be the syntax to check inside a visual basic form panel for checkboxes and find which are checked? I understand how I Could use a for loop and an if statement, but I'm confused as to the syntax to check for each checkbox. for example:
Dim i As Integer
For i = 1 To 10
'Here is where my code would go.
'I could have ten checkboxes named in sequence (cb1, cb2, etc),
'but how could I put i inside the name to test each checkbox?
