View 4 Replieshow to pass a C# ASP.NET array to a Javascript array? Sample code will also be nice.
Let's say for simplicity that in my aspx.cs file I declare:
int [] numbers = new int[5];
now I want to pass "numbers" to the client side and use the data in the array within javascript. How would I do this?
How do I get the width of a control in javascript if it hasn't been set by a css file declaration, a Style declaration, or a skinID.
I have tried control.width, control.getAttribute.width, and I get nothing!
I know that I can declare an array using the following method, but assume there is an easier way.
var elem as new Array();
elem[0] = 1;
elem[1] = 2;
elem[2] = 3;
and so on......
Is there a short cut to simply adding the numbers 0 -20 to an array, and is there a shotcut to adding the 20 nuumbers minus a few such as 3, 9, and 17?
I now that I can just define the width and height of a page with the div tag to allow for dragpanels to work, but it messes things up with some browsers when rendering, sometimes shrinking the actual content to allow for the complete page and width to be shown such as on the IPAD. I have tried the Javascript below, but it doesn't work, and whenever I try to resize a page manually, it puts my computer into never never land.
Anyone have a clean Javascript that will change the width and height dynamically as I am moving a dragpanel.
I can move the dragpanel, but it snaps back as soon as I let go so in essense it doesn't work.

I had a datagrid with lot of columns.The datagrid coloumns width changes accoprding to data.
So I want to get the width of the column in Javascript,because I maintain a dummy header(**here I need to set the each Header column width according to the data columns width).
I would just simply like to change the size of an image or panel when hovering over it. What is the simplest way to accomplish tha?

MY Drop Down width is Different in IE and Mozilla
How to make constant width in both browsers.
I have a dropdown list in a gridview field. The DataValueField for the ddl is an 8 digit item code. The text to display through will be quite longer, 40-60 characters because it will combine the item code and item name into a single string. I don't want the dropdownlist field to be that wide though, only what is displayed when the ddl is selected.In Access you can set the width property of the list to display wider than the field itself. Is there that capability in ASP.NET and if so where do I find it?
View 2 RepliesIs there any way to set the width of a GridView to a pre-determined width?
I have set the width of the gridview and all the columns to a % and then to a number of pixels but it does work. The gridview always sets itself to a width required to display all fields and it goes beyond the resolution of the screen. I would like to contain it to 1024 pixels.

View 1 RepliesI have a GridView in a div wrapper, there is some row headers along the left side that need to be always visible. This all works so far, but I need the wrapper to have a variable width to fit the browser size.
I got the desired width of the wrapper based on the browser width using some javascript but I can't figure out how to set this width as the wrapper.width.It doesn't have to update the wrapper width after the page loads or check for browser resizing.
my poor attempt at diagramming:
| |column headers |
| R |--------------|
| O | gridview data |
| W | |
| | this part |
| H | will scroll |<--->
| E | while the |
| A | Row headers |
| D | stay there |
| E | |
| R |______________ |
| S | scroll bar |
asp:(see edit below)
<pseudocode>
<table>
<tr><td>row headers</td> [code]...
I either need a way to set the wrapper.width = Width or a completely different and hopefully better way to achieve this.
I tried using a % for the width but it doesn't use the browser window as 100%, it takes the % of the full width of the whole GridView
which does nothing for me.
Edit: added some code
<script type="text/javascript">
var Width = window.innerWidth - 275 || document.body.clientWidth - 275;
var divElement = document.getElementById("wrappist");[code]....

I want to get the current width of an html form using javascript. I'm writing this in asp.net
Form definition: <form id="form1" runat="server">
What I an trying: document.getElementById('form1').style.width
Trying to push some coordinates, as well as some stuff specified in a form by the user, to an an array called "seatsArray". Here's my code:
<div>
<img onLoad="shiftzoom.add(this,{showcoords:true,relativecoords:true,zoom:100});" id="image" src="plan1.bmp" width="1024" height="768">
</div>
<script type="text/javascript">
var seatsArray = [];
</script>
<br><input id="backnave" type="radio" name="area" value="backnave" /> Back Nave<br>
<input id="frontnave" type="radio" name="area" value="frontnave" /> Front nave<br>
<input id="middlenave" type="radio" name="area" value="middlenave" /> Middle nave<br>
<input type="radio" id="standardseat" name="seat" /><label for="radio1">Standard</label><br>
<input type="radio" id="wheelchairseat" name="seat" checked="checked" /><label for="radio2">Wheelchair</label><br>
<form id="my_form" action="savetext.aspx" method="post" onsubmit="return prepare()">
<input type="text" id="file_name" name="file_name" rows="1" cols="20" />
<input type="hidden" name="seatsArray" />
<input type="submit" value="Save" />
</form>
<form id="my_form" action="savetext.aspx" method="post" onsubmit="return prepare()">
<input type="text" id="file_name" name="file_name" rows="1" cols="20" />
<input type="hidden" name="seatsArray" />
<input type="submit" value="Save" />
</form>
<script type="text/javascript">
function prepare();
{
document.getElementById('seatsArray').value = seatsArray.join();
return true;
}
</script>
<script type="text/javascript">
var coordinates = document.getElementById("image");
coordinates.onclick = function(e) {
e = e || window.event;
if (e && e.pageX && e.pageX) {
e.posX = e.pageX;
e.posY = e.pageY;
} else if (e && e.clientX && e.clientY) {
var scr = {x:0,y:0},
object = e.srcElement || e.target;
//legendary get scrolled
for (;object.parentNode;object = object.parentNode) {
scr['x'] += object.scrollLeft;
scr['y'] += object.scrollTop;
}
e.posX = e.clientX + scr.x;
e.posY = e.clientY + scr.y;
}
var desc = "";
if(document.getElementByID("backnave").checked) {
desc = "BN, "+desc;
} else if(document.getElementByID("middlenave").checked) {
desc = "MN, "+desc;
} else if(document.getElementByID("frontnave").checked) {
desc = "FN, "+desc;
}
if(document.getElementById('wheelchairseat').checked) {
//Wheelchair seat is checked
desc = "Wheelchair "+desc;
}
seatsArray.push(desc + e.posX, e.posY);
}
</script>
But simply nothing is getting pushed to the array. I can tell this as I am using the following ASP.NET to write the array to a text file:
<script runat="server">
protected void Page_Load(object sender, EventArgs e)
{
string path = Server.MapPath(".")+"/"+Request.Form["file_name"] + ".txt";
if (!File.Exists(path))
{
using (StreamWriter sw = File.CreateText(path))
{
sw.WriteLine(Request.Form["seatsArray"]);
sw.WriteLine("");
}
}
using (StreamReader sr = File.OpenText(path))
{
string s = "";
while ((s = sr.ReadLine()) != null)
{
Response.Write(s);
}
}
}
</script>
The name of the text file is correct according to what the user put in the form "file_name". As you can see I made seatsArray a hidden form object so thats what the ASP.NET is trying to call.
Is something in the javascript in the wrong order or something? Because I just can't get it to fill up that text file.
How Can i fill an array that defined in javascript with c# in behind code?

here is my code

View 2 RepliesI would to know how to pass variables. I have a variable in javascript but I dont know how to pass it to a textbox. I have read it is so easy using ajax, but I dont know how to use it. I believed this was just for not to have reload. Well, then how do I do it? I read I must use get and post, but I dont know how to use it.. for example I have the code:
function guardar() {
var completo = "hola mundo";
}
How do I get the variable completo to pass it in a textbox?
I have the following code:
<script type="text/javascript">
var checksSinceLastPostBack = new Array();
function clientSelectedIndexChanged(sender, eventArgs) {
var ajaxManager = $find("<%= RadAjaxManager.GetCurrent(Page).ClientID %>");
var serializedCheckData = checksSinceLastPostBack.serializeArray();
if (ajaxManager != null)
ajaxManager.ajaxRequest(serializedCheckData);
}
</script>
The
var serializedCheckData = checksSinceLastPostBack.serializeArray();
doesn't seem to work. Am I misunderstanding this?
Also if this works, how would I deserialize it in the code behind?
I have a datatable that I need to convert into a javascript array. This will allow me to do client-side validations on my webpage.
My datatable has 6 columns. X rows depending of the query results.
I was looking to use Me.ClientScript.RegisterArrayDeclaration but I just can't find how to build my 2-dimentional array to feed to this declaration.
On google I found some exemple for a 1-dimensional array, but nothing for 2-dimentional and I am not good enough in Jscript to figure it out myself.
