編集モードでテキスト ボックスの値を取得していません。
私は次のコードを持っています:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not IsPostBack Then
bindList()
End If
End Sub
Private Sub bindList()
gc.BindGridView(dlAgents, "select * from AgentMaster")
End Sub
Protected Sub dlAgents_EditCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataListCommandEventArgs) Handles dlAgents.EditCommand
dlAgents.EditItemIndex = e.Item.ItemIndex
bindList()
End Sub
Protected Sub dlAgents_ItemCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataListCommandEventArgs) Handles dlAgents.ItemCommand
If e.CommandName = "Edit" Then
dlAgents.EditItemIndex = e.Item.ItemIndex
bindList()
End If
If e.CommandName = "CEdit" Then
gc.ExecuteCommand("update AgentMaster set Address='" & CType(e.Item.FindControl("txtAddress"), TextBox).Text & "' , ContactNo='" & CType(e.Item.FindControl("txtContact"), TextBox).Text & "' where agentid='" & e.CommandArgument & "'")
End If
End Sub
Protected Sub dlAgents_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DataListItemEventArgs) Handles dlAgents.ItemDataBound
If e.Item.ItemType = ListItemType.AlternatingItem Or e.Item.ItemType = ListItemType.Item Then
CType(e.Item.FindControl("lblName"), Label).Text = e.Item.DataItem("AgentName")
CType(e.Item.FindControl("lblAddress"), Label).Text = e.Item.DataItem("Address")
CType(e.Item.FindControl("lblContactNo"), Label).Text = e.Item.DataItem("ContactNo")
CType(e.Item.FindControl("lnkLoginID"), LinkButton).Text = e.Item.DataItem("LoginEmailID")
End If
End Sub
ItemCommand では、入力してもテキスト ボックスに空白の値が表示されます。
CType(e.Item.FindControl("txtAddress"), TextBox).Textこれにより、ItemCommand が空白になっていることがわかります。そのため、リストを更新できません。
私を助けてください。
C# での回答も役立ちます。
