将查询字符串中的多个选定复选框值传递给另一个页面 [英] passing multiple selected checkbox values in query string to another page ?

问题描述

我使用了gridview和复选框来选择gridview中的项....我可以轻松选择值...当我一次选择一行然后使用查询字符串我可以很容易地传递id选中的行，但是当我在字段中选择多行时，我不知道如何传递整数数组[即id值到另一个字段]

i have used a gridview and checkbox to select the items in the gridview....I can select the values easily...when i am selecting one row at a time then using query string i can easily pass the id of the selected row but when i am selecting multiple rows in the field,i dont know how to pass the array of integers[i.e id value to another field]

Protected Sub Gridparent_SelectedIndexChanged(sender As Object, e As System.EventArgs) Handles Gridparent.SelectedIndexChanged
    
    If Gridparent.Rows.Count > 0 Then

        For Each gvrow As GridViewRow In Gridparent.Rows
            Dim chk As CheckBox = DirectCast(row.FindControl("CheckBox2"), CheckBox)
            If chk.Checked = True Then
                Dim gid As String = DirectCast(gvrow.FindControl("lbtrans"), Label).Text
                HiddenField1.Value = gid
            End If
        Next
    End If

< br $> b $ b



然后在另一个gridview rowdatabound事件中我传递查询字符串我正在使用此代码：

then at another gridview rowdatabound event where i am passing the query string i am using this code :

Dim transid As String = HiddenField1.Value
Dim wempid As String = HiddenField3.Value
Dim hyperLink = TryCast(e.Row.FindControl("HyperLink1"), HyperLink)
If hyperLink IsNot Nothing Then
    If HiddenField7.Value = 0 Then
        hyperLink.NavigateUrl = "Leaveauth.aspx?wempno=" & Request.QueryString("wempno") & "&transid=" & transid & "&wempid=" & wempid & "&keyd=" & keyd & ""
        hyperLink.Attributes.Add("class", "fancybox")
        HiddenField7.Value = 1
    Else
        'hyperLink.NavigateUrl = "#"
    End If
End If

推荐答案

我认为你必须把它作为逗号分隔的字符串发送。



祝你好运

Hi,
I think you have to send it as a comma separated string.

Good Luck
