我想從GridView中刪除多行,但我很努力地發現是否勾選了一個複選框。Gridview多重刪除
此刻我的代碼並沒有試圖刪除任何東西只是檢查哪些複選框被選中,哪些不是。我的嘗試沒有顯示任何複選框被檢查,並似乎循環兩次GridView行!
.ASPX
<asp:GridView ID="gvImages" DataKeyNames="id" runat="server" AutoGenerateColumns="False" BorderWidth="0px" GridLines="None">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox ID="imageId" runat="server" />
</ItemTemplate>
</asp:TemplateField>
<asp:ImageField DataImageUrlField="image_path" DataImageUrlFormatString="~/admin/images/{0}"></asp:ImageField>
<asp:BoundField DataField="id" />
</Columns>
</asp:GridView>
<asp:Button
ID="btnMultipleRowDelete"
OnClick="btnMultipleRowDelete_Click"
runat="server"
Text="Delete Rows" />
後面的代碼
Protected Sub btnMultipleRowDelete_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnMultipleRowDelete.Click
' Looping through all the rows in the GridView
For Each row As GridViewRow In gvImages.Rows
Dim checkbox As CheckBox = CType(row.FindControl("imageId"), CheckBox)
Dim rowID As Integer = Convert.ToInt32(gvImages.DataKeys(row.RowIndex).Value)
'Check if the checkbox is checked.
If checkbox.Checked Then
Response.Write("Deleted" & rowID & "<br />")
Else
Response.Write("Not deleted: " & rowID & "<br />")
End If
Next row
End Sub
感謝您的幫助。 J.
OnRowDeleting?我不是指這個事件。我做了一個非常類似的事情,當刪除多行和重新綁定時發佈回來也抓到我了 – Curt 2011-03-07 17:24:57
