【问题描述】:
我有一个在运行时填充的网络数据网格(每次用户点击不同的按钮时,它会加载不同的信息)
问题是在selected row change 上,网格没有得到正确的行,因为它进行了回发,并删除了网格中的数据
Protected Sub grid_load(ByVal sender As Object, ByVal e As System.EventArgs) Handles WebDataGrid1.Load
If Not IsPostBack Then
Me.WebDataGrid1.DataSource = Membership.FindUsersByName("A%")
Me.WebDataGrid1.DataBind()
End If
End Sub
Protected Sub WebDataGrid1_Selection_RowSelectionChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles WebDataGrid1.RowSelectionChanged
Dim thisrow = e.CurrentSelectedRows
End sub
thisrow 始终等于 Nothing
如何让 databind() 在回发中持久化,以便我可以访问所选行中的信息?
<ig:WebDataGrid ID="WebDataGrid1" runat="server" AutoGenerateColumns="False" Width="750px" AltItemCssClass="AltRows" >
<Columns>
<ig:BoundDataField DataFieldName="UserName" DataType="System.String" Key="UserName">
<Header Text="User Name">
</Header>
</ig:BoundDataField>
<ig:BoundDataField DataFieldName="Email" Key="Email">
<Header Text="Email">
</Header>
</ig:BoundDataField>
<ig:BoundCheckBoxField DataFieldName="IsApproved" Key="IsApproved" Width="75px">
<Header Text="Approved">
</Header>
</ig:BoundCheckBoxField>
<ig:BoundCheckBoxField DataFieldName="IsLockedOut" Key="IsLockedOut" Width="100px">
<Header Text="Locked Out">
</Header>
</ig:BoundCheckBoxField>
<ig:BoundDataField DataFieldName="LastLoginDate" Key="LastLoginDate">
<Header Text="LastLoginDate">
</Header>
</ig:BoundDataField>
</Columns>
<Behaviors>
<ig:Selection CellClickAction="Row" CellSelectType="None" RowSelectType="Single">
<SelectionClientEvents RowSelectionChanged="WebDataGrid1_Selection_RowSelectionChanged" />
<AutoPostBackFlags RowSelectionChanged="True" />
</ig:Selection>

</ig:WebDataGrid>
