To see the history object in javascript you can have a look at these link:
http://www.irt.org/script/history.htm
and also you can have a look to :
Response.Cache.SetCacheability
through this also you can prevent the page from being cached.

Yes you can you can use javascript to set the focus and yes that javascript you can write in code behind also. Do you want to do it at load of the page or some other time?

Sir,
At page load .Can u help me by sending some code.
Please help.
|
|
|
|

this is the codebehind part:
string str = "<script language='javascript'>";<br />
str += "function Focu(){";<br />
str += "document.getElementById('TextBox3').focus();}<";<br />
str += "/";<br />
str += "script>";<br />
if(!IsStartupScriptRegistered("Test"))<br />
{<br />
Page.RegisterStartupScript("Test",str);<br />
}
And this "Focu" function you have to call in the onload event of the body tag.

In code behind file include this code.
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
setfocus(textboxid,me)
End sub
Private Sub setFocus(ByVal ctrl As Control, ByVal page As Page)
Dim s As String = "<SCRIPT language='javascript'>document.getElementById('" + ctrl.ID + "').focus() </SCRIPT>"
page.RegisterStartupScript("focus", s)
End Sub

Hi,
I have a gridview with Edit.After updating gridview again i binddata().
protected void GridView1_RowUpdating(Object sender, GridViewUpdateEventArgs e)
{
int qty;
int p;
int c;
qty = Convert.ToInt32(((TextBox)GridView1.Rows[e.RowIndex].FindControl("TextBox1")).Text);
Label t = (Label)GridView1.Rows[e.RowIndex].FindControl("Label4");
c = Convert.ToInt32(t.Text);
//c = Convert.ToInt32(((TextBox)GridView1.Rows[e.RowIndex].FindControl("TextBox4")).Text);
p = Convert.ToInt32(((Label)GridView1.Rows[e.RowIndex].FindControl("Label5")).Text);
shopcart.updatecartitems(c, p, qty);
binddata();
For BindData() code is
void binddata()
{
int i = Convert.ToInt32(Session["cartid"]);
DataSet ds = shopcart.getitemsfromcart(i);
GridView1.DataSource = ds;
GridView1.DataBind();
}
after updating even iam binding new data to gridview the row is still displaying textbox(with empty)In database the row is updated.but gridview binding not displaying updated data.Gridview displaying textbox with empty.
After editing any command is there like endedit.
Please help me.
Thanks in advance

I had this problem once before and the way I handled it was to refresh the page after updating the row using Response.Redirect() then add the data binding code in the PageLoad event handler.

Hi... Good Day!!
I have a database table which use as a temporary table to store the edited and new added data. I wish to flush away this table data when i finish printing out the data in this table.
My question is is it possible to flush away the data in the temporary table in database. If yes, how is the coding looks like? Anyone can give me a guide? Thanks.... 
Best Regards,
Pei Sun

Iam not sure I got your clue...
If you use DataTable to store the data, so to let flush away, just clear all...

Thanks. I'm not using the data table to store the data. Is that possible in the .aspx page, i use the commmand to create a temporary table to store the new data and then clear it when the data is not usable already? Can you give me some guide? Thanks

Hi

If so, you just use the SQL query DROP TABLE... to drop the table or just use DELETE FROM... query to delete all records

In your EditTemplate use a label instead of a Textbox
only two letters away from being an asset

This is a basic question. When would one decide to make an user control and when would you want to add the controls to the aspx page itself?
My idea was that whenever you want to add some new event to the existing control/s you would make use of the control and then add events to it. But is there any other reason why you would want to make a new control?
Also if i dont need any new events, all i do is put all the controls (that normally i would put in aspx page) in a ascx page and then just add this to my page - would i get any benefit ? like in performace?
Any help will be greatly appreciated ..

My biggest reason for using user controls is ...reusability.
For example, I have a "Departments" dropdown list that pulls its data from a database. If I only use this on one webform, then maybe I'll just use a dropdownlist on that one form and code to populate it. But using it on many web forms, I get a benefit from creating/coding it once as its own user control, then using the user control on each of the web forms.
|
|
|
|
|
ummm.. makes sense. But then would i get any other benefit? I could always paste the same code without any changes.
|
|
|
|
|
Yes, you could always copy/paste the same code several times.
On the other hand, if you ended up needing to make a minor change to that "Departments" dropdown, would you really want to have to make the change several times? Setting it up as a user control in the first place ensures that you only have to change it once.
|

ah ok.
The reason I am really confused is that I have joined this new project where they insist on making controls for each and every page. None of them can be reused as they are making one ascx page for one aspx page. I just wanted to figure out if doing so is adding any advantage or is this just some kind of design that just deosnt make any sense to me

Oh. I'm not sure why they would want to make each page a single .ascx. I don't see any advantage to that. Unless the goal was to have a single .aspx page that could dynamically swap out any of a number of .ascx's, I suppose... but otherwise, I can't think of a reason to do it that way.
Have you asked your project partners? What reason do they give?
|
|
|
|

oh the guy who is the decision maker is working on .NET for the first time and i have no idea why he insists on making use of such things just because its a part of the technology or because he's new to it or because he just is complicating things
when asked all he says is that we might use it some day. So i was wondering if you know there really is some advantage behind just creating so many user controls.

I'd say it's good practice to build controls in such a way that promotes reuse, even if the possibility of reuse hasn't yet become apparent. May as well write it in a way that's most likely to help you later. Building each page as a single control makes sense only if you're using ASP.NET 1.1 and you need multiple pages to be hosted in one URL, so they can share viewstate.

hi shilpa,
I have also work on a project which is contain all user controls ecexpt on aspx web page which is load every user controls.
I thinks lots of advantage
like reusable is comman advantage and One of most advantages of user controls is that they can expose properties and methods like any object in the .NET Framework.
