使用按钮单击事件的radiobutton.checked值 [英] radiobutton.checked value with button click event

问题描述

大家好，



我有一个网页包含两个选项按钮和命令按钮。我需要检查命令按钮事件中的radiobutton.checked值。问题是在单击命令按钮后单选按钮选项松开其值，因此if语句将永远不会工作。怎么预防这个？有人可以帮我吗？



代码：

hi all,

i have a web page contains two option buttons and command button. i need to check the radiobutton.checked value in the command button event. the problem is after clicking the command button the radio button option loose its value, so the if statement will never work. how to prevent this? can anyone help me please?

the code:

Protected Sub btnSave_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnSave.Click
       
            For i = 1 To tblResult.Rows(0).Cells.Count - 1
                obj = tblResult.Rows(0).Cells(i).Controls(0)
                formIdOption = obj
                If formIdOption.Checked Then
                    formId = CInt(formIdOption.ID)
                    Exit For
                End If
            Next
End Sub

formIdOption.Checked永远是假的。

formIdOption.Checked is always false.

推荐答案

试试这个

try this

Dim rb As New RadioButton()
For Each tr As TableRow In QuestionTable.Controls
	For Each tc As TableCell In tr.Controls
		If TypeOf tc.Controls(0) Is RadioButton Then
			rb = DirectCast(tc.Controls(0), RadioButton)
			If rb.Checked Then
				Dim aa As String = rb.ID
			End If
			Exit For
		End If
	Next
Next

希望这有助于
