Question

我打算在更新传递地址链接按钮中放置保存和取消按钮。你对这个问题有什么建议？我如何解决这个问题？

<div class="form-group">
    <label class="control-label col-lg-4">Delivery Address(Optional)</label>
    <div class="col-lg-8">
        <asp:LinkButton ID="UpdateAddress" runat="server" OnClick="UpdateAddress_Click" Text="Update Address" CssClass="btn btn-default" />
    </div>
</div>
<div class="form-group" visible="false" runat="server" id="Street2">
    <label class="control-label col-lg-4">Street</label>
    <div class="col-lg-8">
        <asp:TextBox ID="txtStreet2" runat="server" class="form-control" MaxLength="50" required />
    </div>
</div>
<div class="form-group" visible="false" runat="server" id="Municapility2">
    <label class="control-label col-lg-4">Municipality</label>
    <div class="col-lg-8">
        <asp:TextBox ID="txtMunicapility2" runat="server" class="form-control" MaxLength="100" required />
    </div>
</div>
<div class="form-group" visible="false" runat="server" id="Region2">
    <label class="control-label col-lg-4">Region</label>
    <div class="col-lg-8">
        <asp:DropDownList ID="ddlRegion2" OnSelectedIndexChanged="ddlRegion2_SelectedIndexChanged" runat="server" class="form-control" AutoPostBack="true" required />
    </div>
</div>
<div class="form-group" visible="false" runat="server" id="City2">
    <label class="control-label col-lg-4">City</label>
    <div class="col-lg-8">
        <asp:DropDownList ID="ddlCity2" runat="server" class="form-control" required />
    </div>
</div>
<div class="col-lg-12">
    <span class="pull-right">
        <asp:Button ID="btnSave" class="btn btn-success" Text="Save" runat="server" />
        <asp:Button ID="btnCancel" class="btn btn-danger" Text="Cancel" runat="server" />
    </span>
</div>

传递LinkButton的C＃代码添加

传递地址的LinkButton的C＃代码

protected void UpdateAddress_Click(object sender, EventArgs e)
{
    UpdateAddress.Visible = false;
    Street2.Visible = true;
    City2.Visible = true;
    Region2.Visible = true;
    Municapility2.Visible = true;
}

这是更新传递地址的保存和取消按钮的代码隐藏文件。

protected void btnSave_Click(object sender, EventArgs e)
{
    con.Open();
    SqlCommand cmd = new SqlCommand();
    cmd.Connection = con;
    cmd.CommandText = "UPDATE Customers SET Street=@Street, Municipality=@Municipality, " +
        "CityID=@CityID, RegionID=@RegionID, FROM Customers WHERE CustomerID=@CustomerID";
    cmd.Parameters.AddWithValue("@Street", txtStreet.Text);
    cmd.Parameters.AddWithValue("@Municipality", txtMunicipality.Text);
    cmd.Parameters.AddWithValue("@CityID", ddlCity.SelectedValue);
    cmd.Parameters.AddWithValue("@RegionID", ddlRegion.SelectedValue);
    cmd.ExecuteNonQuery();
    con.Close();
    Response.Redirect("/Accounts/Checkout.aspx");
}
protected void btnCancel_Click(object sender, EventArgs e)
{
    con.Open();
    SqlCommand cmd = new SqlCommand();
    cmd.Connection = con;
    cmd.CommandText = "UPDATE Customers SET Street=@Street, Municipality=@Municipality, " +
        "CityID=@CityID, RegionID=@RegionID, FROM Customers WHERE CustomerID=@CustomerID";
    cmd.Parameters.AddWithValue("@Street", txtStreet.Text);
    cmd.Parameters.AddWithValue("@Municipality", txtMunicipality.Text);
    cmd.Parameters.AddWithValue("@CityID", ddlCity.SelectedValue);
    cmd.Parameters.AddWithValue("@RegionID", ddlRegion.SelectedValue);
    cmd.ExecuteNonQuery();
    con.Close();
    Response.Redirect("/Accounts/Checkout.aspx");
}

可视化我的问题Hiding of the Buttons in Delivery Address

Answer 1

要使用隐藏按钮启动，我认为您可以使用Visible =“false”

  <asp:Button ID="btnSave"   Visible="false" ... />
  <asp:Button ID="btnCancel" Visible="false" ... />

单击“传递地址”按钮时，将其显示为：

  protected void UpdateAddress_Click(object sender, EventArgs e)
  {
      btnSave.Visible = true;
      btnCancel.Visible = true;
  }

要在单击其他控件时隐藏它们：

  protected void btnCancel_Click(object sender, EventArgs e)
  {
      btnSave.Visible = false;
      btnCancel.Visible = false;
  }
