我已经在这几个小时了,在这里找不到问题。我有 3 页,其中 2 页有更新并且工作正常,但这不是我希望有人能够找到问题所在。
一切都“似乎”正常工作,我看到“成功更新”消息,但它只是没有更新数据。
以下是相关的代码片段:
澳交所:
<asp:Repeater ID="TestDataList" runat="server" onItemCommand="Item_Command">
<ItemTemplate>
<div class='<%# Container.ItemIndex % 2 == 0 ? "list-wrap" : "list-wrap alternate" %>'>
<a href="#" class="edit-list icon-pencil icon-large"></a>
<div class="update">
<span class="dl-content">
<h2><asp:Label ID="TestNameDisplay" runat="server" CssClass="name" Text='<%# Eval("TestName") %>'/></h2>
</span>
<asp:LinkButton ID="deleteTestCase" CssClass="delete-list icon-trash icon-large" runat="server" CommandName="deleteTestCase" CommandArgument='<%#Eval("TestCaseID")%>'/>
<%--edit form--%>
<span class="dl-update">
<asp:TextBox ID="TxtUpdateTestName" runat="server" CssClass='textEntry' Text='<%#Eval("TestName")%>'></asp:TextBox>
<asp:LinkButton ID="EditTestNameButton" runat="server" Text="Save" CommandName="SelectTestName" CommandArgument='<%#Eval("TestCaseID")%>' ValidationGroup='<%# "UpdateTestCaseName" + Eval("TestCaseID") %>' />

</span>
</div>
</ItemTemplate>
</asp:Repeater>
代码背后:
protected void Item_Command(Object sender, RepeaterCommandEventArgs e)
{
if (e.CommandName == "SelectTestName")
{
string setTestNameSQL = "UPDATE TestCases SET TestName = @TestName WHERE TestCaseID = " + e.CommandArgument;
SqlConnection conn = new SqlConnection(GetConnectionString());
SqlCommand cmdUpdateTestName = new SqlCommand(setTestNameSQL, conn);
TextBox tb = (TextBox)e.Item.FindControl("TxtUpdateTestName");
SqlParameter u1 = new SqlParameter("TestName", tb.Text);
SqlParameter u2 = new SqlParameter("TestCaseID", e.CommandArgument);
cmdUpdateTestName.Parameters.Add(u1);
cmdUpdateTestName.Parameters.Add(u2);
try
{
conn.Open();
cmdUpdateTestName.ExecuteNonQuery();
PopulateTestList();
lblUserFeedbackMessage.Text = "Sucessfully updated!";
}
catch (System.Data.SqlClient.SqlException ex)
{
string msg = "Update Error:";
msg += ex.Message;
throw new Exception(msg);
}
finally
{
conn.Close();
}
