แต่ไหนที่นี้คือ มันเอาค่า id ลำดับสุดท้าย แสดง ไม่ใช่ตัวที่เราคลิกเลือก จะมีวิธีแก้ไขยังไงค่ะ
มีโค้ดตัวอย่าง
Protected Sub GVshowName_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GVshowName.RowDataBound
Dim CurrentRowView As System.Data.DataRowView = e.Row.DataItem
If e.Row.RowType = DataControlRowType.DataRow Then
Dim ibnAttachFile As ImageButton = CType(e.Row.FindControl("ibnAttachFileEmployee"), ImageButton)

dbCommand.Connection = dbConnection
Dim dbParam_activity_project_id As System.Data.IDataParameter = New System.Data.SqlClient.SqlParameter
dbParam_activity_project_id.ParameterName = "@id"
dbParam_activity_project_id.Value = GVshowName.SelectedIndex
dbParam_activity_project_id.DbType = System.Data.DbType.StringFixedLength
dbCommand.Parameters.Add(dbParam_activity_project_id)
Dim dataAdapter As System.Data.IDbDataAdapter = New System.Data.SqlClient.SqlDataAdapter
dataAdapter.SelectCommand = dbCommand
Dim dataSet As System.Data.DataSet = New System.Data.DataSet
dataAdapter.Fill(dataSet)
Dim myurl As String = "displaypdf.aspx"
If dataSet.Tables(0).Rows.Count <> 0 Then
If Len(dataSet.Tables(0).Rows(0).Item("rule_url").ToString) > 3 Then
Session("pdfpath") = dataSet.Tables(0).Rows(0).Item("rule_url").ToString
End If
End If
If Session("usertype") = "hi_user" Or Session("usertype") = "admin" Then
myurl = "displaypdf.aspx"
ElseIf Session("usertype") = "mid_user" Then
If Session("rule_level").ToString = "1" Then
Response.Redirect("displaypdf_admin.aspx")
Else
myurl = "displaypdf.aspx"
End If
Else
myurl = "contactinfo.aspx"
End If
ibnAttachFile.PostBackUrl = String.Format(myurl)
End If
If e.Row.RowType = DataControlRowType.DataRow Then
Dim ibnAttachFile As ImageButton = CType(e.Row.FindControl("ibnAttachFileEmployee"), ImageButton)
ibnAttachFile.CommandArgument = GridView1.DataKeys(e.Rows.RowIndex).Value
แล้วเวลาคลิกก็ใช้ event OnCommand และ CommandEventHandler และ CommandEventArgs e
เวลาอ้างอิง id ก็ใช้ e.CommandArgument
Code (VB.NET)
Private Sub ibnAttachFile_Command(ByVal sender As Object, ByVal e As CommandEventArgs) Handles ibnAttachFile.Command
Dim ID As String
ID = e.CommandArgument
End Sub
