function KeyCheck(myfield,e)
{
var keycode;
if (window.event) keycode = window.event.keyCode;
else if (e) keycode = e.which;
else return true;
if (((keycode>47) && (keycode<58) ) || (keycode==8)) { return true; }
else return false;
}
You can use this function for keypress so that it will not allow u to put any characters but only numeric.
If you have a HTML control then call this function by onkeypress="return KeyCheck(this,event);"
Else on server side code write TxtPhone.Attributes.Add("onkeypress","return KeyCheck(this,event)");

how can i create a session in asp.net2005 using c#
dcjoshi2
|
|
|
|

Every time an user open your site on a browser window, it create a session automatically
Create a session variable with the user Id
string userId = (to consult the database)....
Session["userId"] = userId;
Check the session State
string stateSession = Session.Mode.ToString();
write these lines on all onload process pages in order to check if the session dont time out
<br />
try<br />
{<br />
string isAlive = Session["userId"].ToString();<br />
}<br />
catch(Exception)
{<br />
Response.Redirect("error.aspx");
}<br />
Ojala sea lo que buscas

Hi,
There is a rule/checkpoint in Accessibility which says that a Web page should work even when Javascript is disabled.
Currently the MouseOver effect functionality in a Web page is achieved by using "onMouseOver && onMouseOut" in javascript. Is there a way in which MouseOver && MouseOut functionality can be provided without using Javascript?
Please let me know.
Thanks in advance
Narendra

What does the mouseover/mouseout achieve?
If it is merely changing colors/layout then you could use CSS with a "hover" selector.
If it is context-help, then you could make links beside every rollover place where the user could get the same information.

Hi,
There is a rule/checkpoint in Accessibility which says that a Web page should work even when Javascript is disabled.
Currently the Close functionality in a Web page is achieved by using "Window.Close()" in javascript. Is there a way in which Close functionality can be provided without uing Javascript? (other than using Close available in File Menu)
Please let me know.

Hi,
so what u basically need is to detect a page refresh and avoid the subsequent update. Refer this link- http://www.codeproject.com/aspnet/Detecting_Refresh.asp
hope this helps you.

there are three solutions
first one
use the negation ispostback command at load page
if(!IsPostBack)
{
update()
}
Second one
open a new page when the update process is already done
update()
response.redirect("update_ok.aspx",true);
third one
open your site onto a browser page whitout browsers bars, use a javascript function

Hi,
I am experienced in C#, but new in ASP.NET. I cannot understand Web page life cycle. If I understand correctly, Web page class is destroyed every time you press the button or something. So I store my properties in ViewState. but there is a problem. I use TextBox to get keyword, which I use for database records retrieval. When i retrieve database records I add dynamically new rows to table with hrefs.
private void LoadData()
{
baseTechPartArray mParts = DataBase3.Get_baseTechPartArray_By_Keyword(KeyWord);
for (int i = 0; i <= mParts.Count - 1; i++)
{
TableRow mRow = new TableRow();
TableCell cellPickup = new TableCell();
TableCell cellName = new TableCell();
TableCell cellCode = new TableCell();
mRow.Cells.Add(cellPickup);
mRow.Cells.Add(cellName);
mRow.Cells.Add(cellCode);
ContainerTable.Rows.Add(mRow);
LinkButton hrefName = new LinkButton();
hrefName.Text = mParts.Get(i).name;
hrefName.Attributes["record_id"] = mParts.Get(i).id.ToString();
LinkButton hrefCode = new LinkButton();
hrefCode.Text = mParts.Get(i).code;
hrefCode.Attributes["record_id"] = mParts.Get(i).id.ToString();
ImageButton mPickupButton = new ImageButton();
mPickupButton.BorderWidth = 0;
mPickupButton.ImageUrl = "../Resources/pickup.gif";
mPickupButton.Attributes["record_id"] = mParts.Get(i).id.ToString();
cellPickup.Controls.Add(mPickupButton);
cellName.Controls.Add(hrefName);
cellCode.Controls.Add(hrefCode);
mPickupButton.Click += new ImageClickEventHandler(mPickupButton_Click);
hrefCode.Click += new EventHandler(hrefCode_Click);
hrefName.Click += new EventHandler(hrefName_Click);
cellPickup.Attributes["width"] = "1%";
cellCode.Attributes["width"] = "30%";
}
}
but Click events does not work until I add Load() method to PageLoad or LoadViewState.
But then some of table rows are still from first page load, I try to clear them, but it does`nt help. What simple framework or principle should I use 1)to get work simple onevent -> 2)add dynamic elements with their events -> 3)use dynamically added control events?
|

|
|
Can you tell me what is the problem, without elaboration.
|
|
|
|
|
The problem is, that everything show up good, but click events does`nt work. When I click on dynamically added hyperlinks, hyperlink click event does`nt run, but page reloads and everything is gone.
|
|
|
|
|
When you are adding controls dynamically to the page, you need to ensure the childcontrol exists on the other call. This you can do either by adding everytime when you call the page.
protected void Page_Load(object sender, EventArgs e)
{
Load();
}
then it works fine.
let me know whether it works or not?
I will on-line only.
