Server controls like Datagrid, DataList, Repeater can have other child controls insidethem. for example DataGrid can have combo box inside datagrid. These child control do not raise there events by themselves, rather they pass the event to the container parent (whichcan be a datagrid, datalist, repeater), which passed to the page as “ItemCommand” event.As the child control send there events to parent this is termed as event bubbling.

Hi,
I know I am going to ask a silly question. But I am fighting with this problem for the last one week and unable to get the result. So please assist me.
I am building a shopping cart project. At a certain point there is a condition that whenever user enters the same product again and again, only the quantity should be updated. I have done that and is working fine.
But the problem is : Suppose I am having a single item in the cart with quantity "1". Whenever I click the browser refresh it automatically increases the quantity of the item.
That is whenever I refresh the page it will update the quantity.
Please assist me as this is a common problem I am facing.
Waiting for the response. Thanks in advance.
If you want I can provide the code as well.I just want to understand the root of this problem. I searched a lot on google but some says "disable the browser refresh".
I don't know what to do.
Please help me out.
cheers,
sneha

When page posts, browser keeps the posted data in cache and sends it again when refresh button is pressed. So all the events executed before will get executed again. To avoid this, do a redirect once you added an item to shopping cart. Redirection will clear the post data.

I mean something like this.
Response.Redirect("confirmation.aspx")In confirmation page, you can inform user that the quantity has been updated. Redirecting to same page will work as well.

Hi
Just Copy Paste the following Code into your page. This is my research into internet on fresher level.....
private bool _refreshState;
public bool _isRefresh;
public bool IsRefresh //
{
get
{
return _isRefresh;//get the value of Refresh click from Internet Explorer
}
}
protected override object SaveViewState()
{
Session["_ISREFRESH"] = _refreshState; //define Session variable and intilize
object[] allstates = new object[2]; //Define object array named allstates
allstates[0] = base.SaveViewState(); //get the base.SaveViewState in allstate array at 0 position
allstates[1] = !_refreshState; //get the allstate array at 1 position from !_refreshState
return allstates;
}
protected override void LoadViewState(object savedState)//function for LoadViewState
{
object[] allstates = (object[])savedState; //Parsing saveState value at allsataes object array
base.LoadViewState(allstates[0]); //Loading viewState value
_refreshState = (bool)allstates[1];
if (Session["_ISREFRESH"] != null)
{
if (_refreshState == (bool)Session["_ISREFRESH"])
_isRefresh = true;
}
else
{ }
}
And use it into your insert operation
protected void btnInsert_Click(object sender, EventArgs e)
{
if (!_isRefresh)
{
Your Insert Operations here...
}
}

Hi
I am developing an application in ASP.NET. The Server os is 2003.
The client is win XP. Now that i am running my application in the client

ASP.NET can't print a page. You need to use JS and work with window.print().
|
|
|
|
|
Can Anybody help me with JS for local printing.
I am using ASP.NET
|
|
|
|
|
for print use a button and at button's property onclintclick="window.print()"
its work properly.

Are you saying that your session is timing out before the limit you set?
|
|
|
|
|
Hi Navneeth,
Exactly. It has to show my user name till I logout. But after some time it is showing as Guest in login view. Why session is getting expired automatically ? Why Session time I set to 1400 is not working ?

It is very tough to find out why session is expiring. It would be good if ASP.NET writes an entry to event log saying the reason for session expiry. Session can expire because of many reasons. Few of them are,
1 - When any config files are changed
2 - When ASP.NET runtime recycles.
Make sure none of the above happens. See this[^] blog where Scott explains some troubleshooting techniques.
Hope that helps

This doesn't really matter, all that matters is that you need to write the client side names of your textboxes as javascript variables, using their clientID method on the server side, so that you're able to access them.

You have to first run the page and then get the name of that textbox at the runtime
suppose the textbox name is Ct001txt_userid then the you can get the value of text box at the run time by following
var c=document.getElelmentById('Ct001txt_userid');
if(c.value=='vinod')
{
alert('Hi You Are Vinod')
}
else
{
alert('Hi You are not Vinod')
}
You can get the value of textbox by other way also
var b=document.getElementById("<%=txt.ClientID%>")
in the second way the name of the Control is the same what is at server end

Work with window.opener. It gives you access to the main window from popup.
