Hi,
I want to automatically generate a unique code based on a text field, eg if i type in carrots i want to generate CAR001. Anyone can help, will it work the same in ASP as with normal windows based forms?
|
|
|
|
|
How do you mean in normal windows based forms? You'll need to hold some record somewhere of the already used codes and write a bit of logic to create your code...

Hi,
how we can generate wizard steps automatically base on variable
for example
when page load check the value of the variable and then crate wizard steps equal to the value of variable and then set the property of each step.
Thanks a ot

Here is a simple example of programmatically creating wizard steps. The trick is to create the steps in the PreInit event of the page.
<%@ Page Language="C#" %>
<script runat="server">
void Page_PreInit(object o, EventArgs e)
{
string[] data = new string[3] {"What is your name? "
,"What is your quest? "
,"What is your favorite color? "
};
for (int i=0; i<data.Length; i++)
{
WizardStep theStep = new WizardStep();
theStep.ID = "Step" + i.ToString();
theStep.Title = "Step " + i.ToString();
theStep.StepType = WizardStepType.Auto;
Label label1 = new Label();
label1.Text = "<br />" + data[i] + "<br />";
theStep.Controls.Add(label1);
TextBox tb1 = new TextBox();
tb1.ID = "txt" + i.ToString();
theStep.Controls.Add(tb1);
wiz1.WizardSteps.Add(theStep);
}
wiz1.ActiveStepIndex=0;
}
</script>
<html>
<head></head>
<body>
<form runat="server">
<h3>Programmatically Adding Steps to Wizard</h3>
<hr />
<asp:Wizard id="wiz1" runat="server"
DisplaySideBar="true"
HeaderText="Wiz1"
BorderWidth="1" BorderColor="#CCCCCC" BorderStyle="Solid"
StepNextButtonText=" Next >> "
StepPreviousButtonText=" << Previous "
FinishCompleteButtonText=" Done! "
CellPadding="4"
>
<HeaderStyle BackColor="#999999"
ForeColor="#FFFFFF"
HorizontalAlign="center"
Font-Size="12" Font-Bold="True"
/>
<SideBarStyle BackColor="#EFEFEF"
/>
</asp:Wizard>
<hr />
</form>
</body>

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

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();

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.
