gridview中的CheckBox选择 [英] CheckBox selection in gridview

问题描述

我有一个gridview，每个项目都有一个复选框列表，现在我需要一个逻辑，如果我选择一个复选框并单击提交按钮弹出一条消息，如果我再次看到gridview的复选框，我会在点击按钮时收到一些消息，如果我没有选择gridview中的任何复选框，我会在标签中收到一条错误消息，说明请选中复选框下载或我的标签中的其他内容。

Hi ,

I have a gridview having a checkbox list against each item , now i need a logic such that if i select a single checkbox and click on submit button a message pop up and if i all the checkbox of the gridview again i get some message on click of the button and if i did not select any checkbox in the gridview i will get an error message in label stating that please select the checkbox to download or something else in my label.

Dim checkboxSelected As Boolean = Mygridview.SelectedIndexes.Count > 0

Dim mycheckboxvalue As Integer = If(checkboxSelected, Mygridview.SelectedDataRow("column_name"), 0)

Dim myString As String = ""

If ( checkboxSelected = true )  Then

For Each row In Mygridview.SelectedDataRows

mycheckboxvalue = row("column_name")

myString &= "  IIf(checkboxSelected, "0", "1")

Next

  mycheckboxvalue  =  0

ShowError("here error displayed ")

End If

Return myString
