Question

我的搜索框带有用户名并在用户列表中搜索问题是我希望程序在收到用户的第一封信时直接搜索

前端

<asp:TextBox ID="TextBox1" 
             class="form-control table-search-input"  
             ontextchanged="TextBox1_TextChanged"  
             AutoPostBack="True"  
             runat="server"  >

protected void TextBox1_TextChanged(object sender, EventArgs e )
{
    int bb=TextBox1.Text.Length;
    adminuserlist2 = adminuserlist2.Where(o => o.AdminUserName.Substring(0,bb) == TextBox1.Text).ToList();

    if (adminuserlist2 != null)
    {

        Table1.Rows.Clear();
        Table1.BorderWidth = 1;
        Table1.BorderStyle = BorderStyle.Groove;

        Table1.GridLines = GridLines.Both;

        TableCell un = new TableCell();
        un.Text = "UserName";
        TableCell pass = new TableCell();
        pass.Text = "Password";
        TableCell email = new TableCell();
        email.Text = "Email";
        TableCell isactives = new TableCell();
        isactives.Text = "IsActive";
        TableCell typename = new TableCell();
        typename.Text = "Type Name";
        TableCell typeid = new TableCell();
        typeid.Text = "Type Id";

        row = new TableRow();
        row.Width = new Unit("120%");
        row.BackColor = System.Drawing.Color.White;
        row.ControlStyle.Font.Size = 25;
        row.ControlStyle.Font.Bold = true;
        row.ControlStyle.ForeColor = System.Drawing.Color.Black;


        row.Controls.Add(un);
        row.Controls.Add(pass);
        row.Controls.Add(email);
        row.Controls.Add(isactives);
        row.Controls.Add(typename);
        row.Controls.Add(typeid);
        Table1.Controls.Add(row);
        row.ControlStyle.Width = 300;
        row.ControlStyle.Height = 30;
        Table1.Width = 500;

        Table1.ControlStyle.Width = 1000;
        Table1.Height = 500;

        Table1.CellSpacing = 50;
        Table1.CellPadding = 50;

        for (int i = 0; i < adminuserlist2.Count; i++)
        {
            TableCell un2 = new TableCell();
            un2.Text = adminuserlist2[i].AdminUserName;
            TableCell pass2 = new TableCell();
            pass2.Text = adminuserlist2[i].AdminUserPassword;
            TableCell email2 = new TableCell();
            email2.Text = adminuserlist2[i].AdminUserEmail;
            TableCell isactives2 = new TableCell();
            isactives2.Text = adminuserlist2[i].IsActive.ToString();
            TableCell typename2 = new TableCell();
            typename2.Text = adminuserlist2[i].AdminUserType;
            TableCell typeid2 = new TableCell();
            typeid2.Text = adminuserlist2[i].AdminUserTypeID.ToString();
            row = new TableRow();
            row.Controls.Add(un2);
            row.Controls.Add(pass2);
            row.Controls.Add(email2);
            row.Controls.Add(isactives2);
            row.Controls.Add(typename2);
            row.Controls.Add(typeid2);
            Table1.Controls.Add(row);
        }
    }

}

我遇到了一个问题，我应该从文本框中单击进行搜索请任何人都可以帮忙

Answer 1

如果你选择try { PackageInfo info = getPackageManager().getPackageInfo( "com.al.name", PackageManager.GET_SIGNATURES); for (Signature signature : info.signatures) { MessageDigest md = MessageDigest.getInstance("SHA"); md.update(signature.toByteArray()); Log.d("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT)); } } catch (NameNotFoundException e) { } catch (NoSuchAlgorithmException e) { }活动而不是OnKeyPress只更改活动并且它将会正常工作

会更好

前端

TextChanged

的后端

<asp:TextBox ID="TextBox1" class="form-control table-search-input" onkeypress="__doPostBack(this.name,'OnKeyPress');" AutoPostBack="True" runat="server" >

Answer 2

在Asp.Net中没有真正的textchanged事件，只有在文本框失去焦点并且你已将autopostback设置为true时才会触发。

您可以做的是以下内容：

将ScriptManager添加到您的aspx页面：

$value = "zkjxhvzkjxcvhnzxv"""!^!^!";
$html = new simple_html_dom();
$html->load('<input type="text" id='myID'>');
$input = $html->getElementById('myID');
$input->setAttribute("value", $value);
echo $html;

在文本框中添加onkeypress clientide事件：

<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true"/>

调用PageMethod：

<asp:TextBox ID="TextBox1" 
         class="form-control table-search-input"  
         ontextchanged="TextBox1_TextChanged"  
         AutoPostBack="True"  
         runat="server" onkeypress="CallMyPageMethod();" >

将PageMethod添加到您的代码后面：

    <script language="javascript" type="text/javascript">
    function CallMyPageMethod() {            
    PageMethods.MyPageMethod();
    }

如何在c＃asp.net？
