它没有在编辑模式下的文本框中取值。
我有以下代码：
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
在ItemCommand中，它显示了文本框的空白值，尽管我输入了它们。
CType(e.Item.FindControl("txtAddress"), TextBox).Text这在ItemCommand上显示空白，这就是为什么我无法更新列表。
请帮帮我。
c＃中的答案也可以帮助我。

您是否忘记将事件附加到网格？
ItemDataBound =“Agents ItemDataBound”
<asp:DataList ID="dlAgents" runat="server" RepeatDirection="Horizontal" RepeatColumns="2"
OnEditCommand="dlAgents_EditCommand"
OnItemDataBound="dlAgents_ItemDataBound"
Width="98%">
