sunflower's questions

I have a form on my web page in which I need that when a user enters a Code in an input in another input, the Name is auto-completed. I have the code shown below, but it does nothing. I have two tables: TablaCodigos: Codigo_p varchar ...

TablePersonas Codigo_p varchar Name varchar ...

my script

<script type="text/javascript">
$("#Codigo_p").change(function () {
$.getJSON("/Solicitud/GetPersona?Codigo_p=" + $("#Codigo_p").val(), function (result) 
{
            var select = $("#nombreP");
            select.empty();
            $.each(result, function (index, itemData) {
            select.append($({
            value: itemData.Nombre
            }));
        });
    });
 }
</script>

my controller

public JsonResult GetPersona(string Codigo_p)
{
  bd.Configuration.ProxyCreationEnabled = false;
  TablaPersonas nom_p = bd.TablaPersonas.Where(x => x.Codigo_p == Codigo_p).Single();
  return Json(nom_p, JsonRequestBehavior.AllowGet);
}             

HTML

<div class="form-group">
<div class="m-0 font-weight-bold text-primary subtitulo">Persona:</div>
<input type="text" class="form-control" id="nombreP" name="nombreP" placeholder="Nombre" readonly="" >
</div>

what I need is that a textbox is disabled and it is enabled until I write 4 numbers in a previous textbox. The textboxes are asp:Textbox. The truth is that I haven't tried it because I don't know how, and it occurs to me that it could be with jquery or from behind code c#. Thank you for reading.

I have a text field asp:textbox which I must enter from 1 to 2 integers from a keyboard created with button type="button", I have not used asp:button because this keyboard and this textbox are inside a bootstrap modal , and if I used an asp:button it just restarted the page and closed the modal. Well the case is that I need to validate the textbox so that it only accepts a certain number of numbers.

I tried it with the validation tools that .net already has but it doesn't work for me, it doesn't let me write anything in the textbox with the buttons, so I removed it and tried it with jquery, but it only limits the space when I write with the keyboard of my pc, and if I write with the keyboard that I did, it does not limit me at all.

I hope I made myself understood. Thank you for reading.

<asp:textbox id="sem" runat="server" autocomplete="off"></asp:textbox>

//Utilice esta función pero como ya dije, si escribo con el teclado que he 
hecho me deja escribir más de 2 números.

function validar(){
	sem=$('#head_sem').val();
	if (sem.length<2){
		return true;
	}
	else {
		alert('Maximo 2 caracteres');
		return false;
		
	}

I have a report with reportviewer of an invoice that brings me data from the DB, I would like to be able to print it without the need to use the preview, that is, do it from programming with a separate button, that is, not use the one that has the reportviewer by default.

I hope you can help me thanks

SOLUTION WITH JQUEY

<!--script para imprimir-->
<script type="text/javascript">
	function Print() {
		var report = document.getElementById("<%=ReportViewer1.ClientID%>");
	var div = report.getElementsByTagName("DIV");

	var reportContents;
	for (var i = 0; i < div.length; i++) {
		if (div[i].id.indexOf("VisibleReportContent") !== -1) {
			reportContents = div[i].innerHTML;
			break;
		}
	}
	var frame1 = document.createElement('iframe');
	frame1.name = "frame1";
	frame1.style.position = "absolute";
	frame1.style.top = "-1000000px";
	document.body.appendChild(frame1);
	var frameDoc = frame1.contentWindow ? frame1.contentWindow : frame1.contentDocument.document ? frame1.contentDocument.document :frame1.contentDocument;
	frameDoc.document.open();
	frameDoc.document.write(reportContents);
	frameDoc.document.write("<style> @page { size: portrait; } .head { display: none; }></style>");
	frameDoc.document.close();
	setTimeout(function () {
		window.frames["frame1"].focus();
		window.frames["frame1"].print();
		document.body.removeChild(frame1);
	}, 500);   
	}

I have a bootstrap modal which contains a textbox and a numeric keypad inside, so when you click on a button, you must "type" the number of the button in the textbox. The problem is that clicking any button (on the modal's keyboard) closes the modal. The number does stay written but to see it I have to open the modal again. Is there a way to make the modal not close?

I read that it can be solved by placing an updatepanel inside the modal body to avoid autopostback... but I have no idea how.

webform aspx.cs
  protected void b0_Click(object sender, EventArgs e)
        {

                sem.Text = sem.Text + "0";
       }

I have a webform1 in which I have a sem.Text textbox. Here is the code to pass that

value to a second webform

private string semana_x;
    public string semana
    {
        get
        {
                return semana_x;                
        }
       set
        {
         semana_x = value;
         this.sem.Text = value;
        }
    }


    protectedvoid b_Click(object sender, EventArgs e)
    {
        Response.Redirect("webf2.aspx?semana=" + semana);
    }

web form 2

//aqui recibo el valor del webf1 y lo convierto a int

int valor;
int.TryParse(Request.QueryString["semana"], out valor);
//para compararlo con un campo de BD

SqlCommand cmd = new SqlCommand("SELECT * from tabla where semana="+valor+",con);
//y mostrar todo en un gridview

SqlDataAdapter da = newSqlDataAdapter(cmd);
            DataTable dt = newDataTable();
            da.Fill(dt);
           gridview1.Visible = true;
           gridview1.DataSource = dt;
           gridview1.DataBind();
         con.Close();
        }

the problem is that when I write the number in the texbox it doesn't show me anything in the table and my

link appears like this: localhost:49236/Project/webf2.aspx?week=

but if I add a number at the end

link like this: webf2.aspx?week=48<-- like this, and if it shows me the data in the gridview

I hope you can help me

Thank you

Hi, I have a project in ASP .NET with C#. I have the following code in my webform1 to pass the value that the user writes to another webform and compare it in an SQL query and it throws me the error:

'Object reference not set to an instance of a get object(refers to webform1's get) returned null.

WebForm1 code:

    public string semana
        {
            get
            {
           return sem.Text; //textbox donde el usuario va a escribir el valor
            }
        }


        protected void button_Click(object sender, EventArgs e)
        {

           if (semana!= null)
           {
                Response.Redirect("webform2.aspx?semana=" + semana);
           }
           else {
              Response.Redirect("webform1.aspx");
           }
        }
}

Webform2 code (here it throws me the error)

int valor = Int32.Parse(PreviousPage.semana);
//aqui esta el valor del webform1 y lo convierto a int




SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["cn"].ToString());
con.Open();
SqlCommand cmd = new SqlCommand("SELECT * from tabla where semana="+valor+",con);

 SqlDataAdapter da = new SqlDataAdapter(cmd);
                DataTable dt = new DataTable();
                da.Fill(dt);
                gridview1.Visible = true;
                gridviwe1.DataSource = dt;
                gridview1.DataBind();
                con.Close();

            } 
    }

I have relied on these pages to pass the value of the webform to the other:

https://msdn.microsoft.com/es-mx/library/6c3yckfw(v=vs.100).aspx https://social.msdn.microsoft.com/Forums/es-ES/af012424-6a31-4273- b9e7-f8ed6b8c233d/passing-data-from-one-web-form-to-another-web-fom-aspnet-with-c?forum=netfxwebes

I hope you can help me.

Thanks. Cheers

I have a webform project in asp .net with c# and in my sql query I need data that the user is going to provide.

The week field is entered in a textbox in webform1 and I have the query in webform2. According to that data, it will show me certain records in a gridview. In addition to the login cod_user. Next I show the code

Mistakes:

*'Value cannot be null. Parameter name: String' of the line: int value = Int32.Parse(Request.QueryString["week"]);

*'The query with parameters '(@cod varchar(5))SELECT blah blah' expects the parameter '@cod', which was not supplied.'

ORIGIN PAGE

   protected void BUTTON1_Click(object sender, EventArgs e)
   {
       string semana = sem.Text;
       if (sem.Text != null)
       {
         Response.Redirect("webform2.aspx?semana=" + semana);
       }
       else {
           Response.Redirect("webform1.aspx");
       }
   }

DESTINATION PAGE

protectedvoid Page_Load(object sender, EventArgs e)
    {
        int valor = Int32.Parse(Request.QueryString["semana"]);// valor que viene de otro webform
       SqlConnection con = newSqlConnection(ConfigurationManager.ConnectionStrings["cn"].ToString());

        con.Open();
            SqlCommand cmd = newSqlCommand("SELECT WHERE(Sem.Semana = '@sem') AND(Cab.Cod_user= '@cod') AND(etc...", con);
         cmd.Parameters.Add("@sem", SqlDbType.TinyInt, 3);
        cmd.Parameters["@sem"].Value = valor;
       cmd.Parameters.Add("@cod", SqlDbType.VarChar, 5);

cmd.Parameters["@cod"].Value = Session["Cod_user"]; 

SqlDataAdapter da = newSqlDataAdapter(cmd);
            DataTable dt = newDataTable();
            da.Fill(dt);
           gridview1.Visible = true;
           gridview1.DataSource = dt;
           gridview.DataBind();
         con.Close();
        }

I have a webform application in ASP .NET with C# and I want to fill a gridview from the webform.aspx.cs. Is there a way to fill "only" when entering the page, or should it be only with a click event. Could you tell me how to do it? Thank you very much for your help Regards

Hello I have created a bootstrap modal and I have removed the ×

and of course it doesn't have a cancel button, just an accept button that takes me to another page. Well, what I need is that my modal does not close with the ESC key or by clicking on another part of the screen (since it also closes), only and only that it stays there and does not close, once the user does click on open modal, I can no longer remove it. Is there any way? Thanks greetings

I am working on an asp .net webform application with c#

Hello, I have a project in ASP .NET with C#, I have a form to change the password, and for this I have a modify button in which, when I click on it, it should show me a modal where a message appears that the password has been modified. and a button where you must click on accept and the session must be closed. This is my code:

protected void btnModificar_Click(object sender, EventArgs e)
        {

            Modificar();//funcion para modificar

//string para mostrar mi modal
            string modalScript = @"<script type=""text/javascript"">
             function openModal() {
                  $('#mymodal').modal('show');
                      }
            </script>";
            ScriptManager.RegisterStartupScript(this, GetType(), "bsChgPwdModal", modalScript, false);//
        }

if it shows me the modal but then "disappears" and I want it to stay there to click the button and close the session. Thank you!! Cheers

I need a button to be disabled until the fields of two TextBoxes are filled.

I use webform with c# in asp.net, I have a form to change the password, and until the fields are filled with their validations already done, the button must be activated. When the two textboxes are filled, the button is enabled, which shows a modal with a message that the pin has been updated and you must close the session.
