Is there a better way to do "input forms" in WebForms?I always end up with code like this:
Double d = 0; // chuckle inside
if(Double.TryParse(myNumberTextField.Text, out d))
{
myObject.DoubleVal = d;
}
Is there a better way to process free-form "numeric" input.
why can images not be appended to a div in asp?
divHtml.append(img);
why do I have to use div.controls.add(img);?
and why cant I add a string to controls.add say like this
div.controls.add(img + String.Format("{0}", reader.GetString(0));
?

ScriptResource.axd is a file dynamically genrated by resource manager so using firbug and idev tool i tried to debug but couldn't..
there I am using xval for the first time, it seems to work fine for required fields, However I am having some issues first of all it does not seem to validate booleans and also client validation is not working for me, this is not a major issue for me, the one that I really need to work is the stringlength property. It seems to do something because the form is not posted when the string length is exceeded, however no error message is displayed to the user which is obviously not what I want, has anyone been able to do this successfully?
My model goes like this
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.ComponentModel.DataAnnotations;
namespace PitchPortal.Core

Which works great until one of the characters in one of the textboxes is ' (apostrophe).

2 string = "stackoverflow is good"
I want to show: "stackoverflow is good".
"is good" should be highlighted with some background-color..how is it possible to do with c#?
I'll use the Math.Round function, but there happends something strange. If i have a numer like 10.0012356 he adds with round(10.0012356) only 10, and not the wanted 10.00 But if i have 10.534, he adds 10.53, so then its ok. How can i change that? I use this code right now:
double PriceIn = PriceExcl * ((BTW + 100)/100);
lblPriceEx.Text = "€" + Math.Round(PriceExcl, 2).ToString();
lblPriceIn.Text = "(" + Math.Round(PriceIn, 2).ToString() + "incl.)";
I found that I don't need to use jQuery or AjaxToolKit to use a textbox with autocomplete instead using the AutoCompleteType() class.However, base in the documentation it says the autocomplete will just trigger after the button was click at first instance, with that
description looks like what I want to do will not be applicable.Is it possible to populate the textbox with a list of strings in page load? so that if I type in a textbox it will give me a complete list of strings already.
My web page allows customers to search products by selecting criteria. In this example, they can choose a height range (we'll use the example between height 2.00 and 2.99). The issue is, the database returns a results which has a height of 3.00 (which is obviously not between 2.00 and 2.99) I am using a stored procedure.
[Code]....
My webpage passes the paramters for @Pr and @Pr2 (which are of type double) to the stored procedure (@Pr = 2.00, @Pr2 = 2.99). My c# code (simplified - FYI, request.QuerysString["p"] returns the string value 2)
[Code]....
You can see from the C# I have commented 2 lines for debugging where I've used the dqsPr variable and where I've typed the number in manually. Regardless of sending either the variable or the actual 'number', the results remain the same (it shows a product which has a height of 3.00). If I change the Stored procedure (for debugging purposes only) Select statement to SELECT DISTINCT PartNumber, Positions, Switch, Post, Profile FROM View WHERE Height BETWEEN 2.00 AND 2.99 ORDER BY Type ASC it works fine. So, it must be due to the passing of the paramaters via ado.net?
Given the code below, how do I compare a List of objects's values with a test value? I'm building a geolocation application. I'll be passing in longitude and latitude and would like to have the service answer back with the location closest to those values. I started down the path of converting to a string, and formatting the values down to two decimal places, but that seemed a bit too ghetto, and I'm looking for a more elegant solution.
public class Location : IEnumerable
{
public string label { get; set; }
public double lat { get; set; }
public double lon { get; set; }
//Implement IEnumerable
public IEnumerator GetEnumerator()
{
return (IEnumerator)this;
}
}
[HandleError]
public class HomeController : Controller
{
private List<Location> myList = new List<Location>
{
new Location {
label="Atlanta Midtown",
lon=33.657674,
lat=-84.423130},
new Location {
label="Atlanta Airport",
lon=33.794151,
lat=-84.387228},
new Location {
label="Stamford, CT",
lon=41.053758,
lat=-73.530979}, ...
}
public static int Main(String[] args)
{
string inLat = "-80.987654";
double dblInLat = double.Parse(inLat);
// here's where I would like to find the closest location to the inLat
// once I figure out this, I'll implement the Longitude, and I'll be set
}
I want to display some text with formatting such as bold, italic, colored...

In my website, there is a page called "SMS Log"It contains a GridView, in which there are 5 columns:
1) SMS sent time
2) SMS Text
3) Recipients
4) status
5) Button (view detail) since, "SMS Text" is large and "Recipients" are more than 1.
So Gridview looks very conjusted, also it does not look good.Is there any other control I can use other than Gridview to show above 5 columns in a well organized way.
I am trying to send data from text fields created on the client side (via jquery). The problem is the data from those text boxes is not being post back ( I'm using asp.net webforms)
I have used fiddler to view the post back data and it isn't there for those generated text fields.
I'm surprised no one figured it out. I was switching from server to non server controls I forgot to give the non ones a name field..........
// Add answer field
$('#addAnswer').click(function ()
{
count++;
var html = '<p>' +
'<input id="answer' + count + '" type="text" maxlength="255" runat="server" />' +
'<a id="removeAnswer" class="removeIcon" href="#"><img class="removeIcon" src="/Content/images/minus.gif" /></a>' +
'</p>'
$(html).appendTo('#answers');
return false;
});
I know now normally you can get the value of a text input using the following:
txtName.Text
But because my input is inside of a LoginView I am using FindControl like this:
LoginView1.FindControl("txtComment")
This successfully find the text input but returns its type rather than the value. Adding the Text function at the end does not work.
Give any sample links for input text will get as hh:mm format .for example if we open system date and time with in single text box we can edit hours and minutes .same like that i need examples in asp.net .
View 2 RepliesI'm working on an ASP.NET/C# app.
I have 2 text boxes and I need to validate if the input text for both of them are not both null
ex:
if(string.IsNullOrEmpty(TextBox1.Text) && string.IsNullOrEmpty(TextBox2.Text) ) //FAIL!!! else
that is, at least one txtBox has values
I was planning on using a custom validator but it seems that the validation function only gets called when something is written on the textBox i'm using has the 'control to validate'. Now, that doesn't work for me since I want to show an error message when both text boxes are empty. Is there a way to make the validation function to be called with, for example a postback? Or is there any other better approach to this case than the custom validator?
I have a table including : StudentID,Mark
and I show them in a list and I want to input marks one by one:
<% foreach (var item in Model) { %>
<tr>
<td>
<%: item.StudentID %>
</td>
<td>
<input type="text" />
</td>
<%}%>
1-how can I save them in database which saves each mark for each StudentID in the list?
2- how can we send focus to next textBox by pressing Enter key in each textbox in the list?
I'm very new to ASP.NET, how would it be possible to have a complete form with, let's say, 10 text boxes. Once the page is displayed, the user would only see the first textbox. After the user has input data into that box, the second textbox would appear. After data is input into the second textbox, the third textbox would appear and so on. I know it probably has something to do with Postback but I cannot find anything on this scenario.
View 8 Replies1. When the user enters a fee, the form should automatically calculate the VAT and add it to the fee when he go to the next textbox. The result should be displayed in a textbox.
2. The user chooses an element from a dropdownlist. The next textboxes are filled in dependence of his choice with text.
Example:
User chooses "1. Quarter" from dropdownlist so text from Textbox1 becomes "01.01." and Textbox2 "31.03."

View 16 RepliesI have the following question on how to do the following:I have developed a website and I want certain users to give to possibility to add a text article to specific pages or maybe into a Forum. These articles are more or less having the same structure like:Big Header, manchet (intro), text with in between small headers. I would like to have this all in the same font-family and depending on the sort of text in a certain font-size.I was thinking of using TinyMCE as a base, because all typographical aspects are in there and it is also possible to add graphics and other video stuff to itt.Is this possible to use this, since I recently found TinyMCE and do not have the knowledge yet about this?And how should the structure be set up?I do hope someone could give some clues or sites where this is discussed.
