【问题描述】：
我想将模式中的数据保存到我的数据库的更新面板中。
我的文本框中的值在变量的保存后面，但数据库中没有保存。我不知道为什么。我每次都使用updModal.Update();，因为模态是通过列表视图从数据库中获取的。
这是我的模态代码：
<div class="modal fade" id="studinfo" role="dialog">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<h4 class="modal-title">Student Info</h4>
<button type="button" class="close"
data-dismiss="modal">
×</button>
</div>
<div class="modal-body">
<asp:UpdatePanel ID="updModal" runat="server" ChildrenAsTriggers="false" UpdateMode="Conditional">

</asp:UpdatePanel>
<asp:Button ID="btnSave" OnClick="btnSave_Click" CausesValidation="false"
CssClass="btn btn-success btn-block" runat="server" Text="Save" />
</div>
</div>
这是保存按钮背后的代码：
protected void btnSave_Click(object sender, EventArgs e)
{
try
{
updModal.Update();
string id = txtId.Text;
SqlCommand cmd = new SqlCommand();
cmd.CommandType = CommandType.Text;
cmd.CommandText = "update tblStudent set stud_result=@res,stud_purcentage=@pur,stud_totalMarks=@marks where stud_Id=@id";
cmd.Parameters.AddWithValue("@id", id);
cmd.Parameters.AddWithValue("@res", ddlResult.SelectedValue);
cmd.Parameters.AddWithValue("@pur", txtpur.Text.Trim());
cmd.Parameters.AddWithValue("@marks", txtMarks.Text.Trim());
con.Open();
cmd.Connection = con;
Label1.Text = txtId.Text;
gridView();
}
catch (Exception ex)
{
ScriptManager.RegisterStartupScript(this, GetType(), "LaunchServerSide",
"$(function () { showUErrorModal(); });", true);
}
finally
{
con.Close();
}
}
【问题讨论】：
-
任何你得到 javascript 或 C# 的错误。
-
没有错误。它只是没有将值发送到数据库。
