如何将datagridview复选框列状态添加到布尔数组 [英] How to add datagridview check box column states to boolean array

问题描述

我有相同形式的datagridview，有些是复选框和组合框列

i尝试将那些列数据（例如复选框状态）设置为布尔数组，将组合框文本设置为字符串数组但是这么多错误按摩来了......有谁知道泰铢怎么样？？





我的目的是那些数组会写入文本文件... < br $> b $ b

我尝试过：

I have few datagridview in same form some are having checkbox and combo box columns
i try to get those column data such as checkbox states to boolean array and combobox text to string array but so many error massages is came.. anyone know How do thais..?


My Purpose is those array will write to text file...

What I have tried:

Public Class Form1

    '// I have insert data grid. its first column is check box and second columns is check box
    '// I want to add to array each row 
    '// And i have few data grid in same form

    Dim data() As String = {}

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        '// For first row 

        For a As Integer = 0 To 5
            data(a) = DataGridView1.Rows(a).Cells(0).Value.ToString
            TextBox1.AppendText(data(a))
        Next
    End Sub

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        DataGridView1.Rows.Add(10)
    End Sub
End Class

推荐答案

CheckState将返回 Checked，Unchecked，Indeterminate 。但是你需要一个布尔值，所以你要查找 Checked 属性，而不是 CheckState 属性。

CheckState will return Checked, Unchecked, Indeterminate. But you need a Boolean value, so you look for the Checked Property, not the CheckState Property.

    For a = 1 To 5

       Dim bool As Boolean
       'assuming Cells(x) is a CheckBox
       bool = DataGridView1.Rows(a).Cells(0).Checked


       data(a-1) = bool.ToString
    Next

End Sub
