动态更改Gridview中的DataField属性
本文关键字:DataField 属性 中的 Gridview 动态 | 更新日期: 2023-09-27 17:58:48
我有一个这样的GridView:
<asp:GridView ID="GridViewAllPeopleEditMode" runat="server"
AutoGenerateColumns="false"
AutoGenerateEditButton="true"
AllowPaging="true"
PageSize="20"
OnRowEditing="GridViewAllPeopleEditMode_RowEditing"
OnRowCancelingEdit="GridViewAllPeopleEditMode_RowCancelingEdit"
OnRowUpdating="GridViewAllPeopleEditMode_RowUpdating"
OnPageIndexChanging="GridViewAllPeopleEditMode_PageIndexChanging">
<Columns>
<asp:BoundField DataField="id" HeaderText="BusinessEntityID" ReadOnly="true"/>
<asp:BoundField DataField="FirstName" HeaderText="FirstName"/>
<asp:BoundField DataField="MiddleName" HeaderText="MiddleName"/>
<asp:BoundField DataField="LastName" HeaderText="LastName"/>
</Columns>
</asp:GridView>
我希望page_load
在设置DataSource()/DataBind()之前先设置DataField属性,而不是自己在.aspx页面中编写它们。
有可能做到这一点吗?或者我必须更改BoundFields吗?非常感谢!
您可以在代码端中这样使用
C#
BoundField field = (BoundField)this.GridViewAllPeopleEditMode.Columns[0];
field.DataField = "To";
VB
Dim field As BoundField = DirectCast(Me.GridViewAllPeopleEditMode.Columns(0), BoundField)
field.DataField = "To"
