Hi,
I'm presently using asp:datagrid control for displaying some data from a table.
But I don't want to continue with this process. I want to have complete control
over the process, like in J2EE where I can populate my result-set and display
what I want, where I want and however I want.
What I mean is: Let's say my table has four columns, and I make four corresponding
variables ASP.NET C#. Now, in a loopy fashion, I want to iterate through my
table as long as there are more rows to be fetched, and each cycle of the loop should
change the values of those C# variables.
(J2EE guys, remember this? -->
while (rs.neext())
{
do_something_baby;
}
I want this in ASP.NET C#.
Sounds archaic? I know, but it's totally fat free, unlike the asp datagrid control.
Any help anyone?
Thanks
ASP - AJAX is SEXY. PERIOD.

In your database command object use ExecuteReader()
while(reader.Read())
{
}

If you want something more lightweight than datagrid you can use the Repeater control. Then for output control, use OnItemDataBound, which will give you control over the data output and let you add controls and specify attributes on the fly as well.

When you take data from the database you vil have to replace linefeeds with a html br-tag.
c#:
string Text = TextFromDatabase.Replce("\n", "<br />");
Response.Write(Text);
vb.net:
Dim Text As String = TextFromDatabase.Replace(VbCrLf, "<br />")
Response.Write(Text)

Hi All,
I am using GridView to display the Data.My problem is that I get the values from DB as ID,Name,Rights(eg:AXXVP;where A-ADD,X-Not allowed,V-View,P-Print).Now I have to put rights in diferent columns named Add Modify delete View and Print,these columns are checkbox and it is checked or unchecked depending upon values Rights column from DB.
Eg:Suppose I get row from DB as 1 User AXXVP
then Gridview will have
ID Name Add Modify Delete View Print
1 User checked unchecked unchecked checked checked
Since X denoted Unchecked.
Please Help.Thanks in Advance...

Hi,
Try this,
Call procedure CheckBoxListValues() on CheckBoxList's OnDataBinding event to show check/uncheck checkbox
Your aspx code....
<aspatagrid id="dg" runat="server" AutoGenerateColumns="False">
<COLUMNS>
<asp:templatecolumn HeaderText="Behörighet">
<ITEMTEMPLATE>
<asp:checkboxlist id="Checkboxlist2" runat="server" Width="544px" DataTextField="Name" DataValueField="ValueField"
RepeatDirection="Vertical" OnDataBinding="CheckBoxListValues">
<asp:ListItem Value="Add" Selected="True">Add</asp:ListItem>
<asp:ListItem Value="Modify">Modify</asp:ListItem>
<asp:ListItem Value="Delete">Delete</asp:ListItem>
<asp:ListItem Value="View">View</asp:ListItem>
<asp:ListItem Value="Print">Print</asp:ListItem>
</asp:checkboxlist>
</ITEMTEMPLATE>
</asp:templatecolumn>
</COLUMNS>
/aspatagrid>
and code behind code is ....
Public Sub CheckBoxListValues(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Checkboxlist2.DataBinding
Dim i As Integer
Dim str As String = "AXXVP" 'Pass value from Database
For i = 0 To Checkboxlist2.Items.Count - 1
Select Case i
Case 0 ' Add
If str.Substring(i, 1) = "A" Then
Checkboxlist2.Items(i).Selected = True
Else
Checkboxlist2.Items(i).Selected = False
End If
Case 1 'Modify
If str.Substring(i, 1) = "M" Then
Checkboxlist2.Items(i).Selected = True
Else
Checkboxlist2.Items(i).Selected = False
End If
Case 2 ' Delete
If str.Substring(i, 1) = "D" Then
Checkboxlist2.Items(i).Selected = True
Else
Checkboxlist2.Items(i).Selected = False
End If
Case 3 'View
If str.Substring(i, 1) = "V" Then
Checkboxlist2.Items(i).Selected = True
Else
Checkboxlist2.Items(i).Selected = False
End If
Case 4 ' Print
If str.Substring(i, 1) = "P" Then
Checkboxlist2.Items(i).Selected = True
Else
Checkboxlist2.Items(i).Selected = False
End If
End Select
Next
End Sub
Hope this will help..

Hi,
I have an application used by customers for sending in warranty-claims.
This is solved by a wizard in 8 steps. On the final step I need to write all the data to a database so our warranty-administration application can process the information.
The problem is when the customer is clicking the Finish-button and then clicks it again.
It seems as if the Finishbuttonclick-method doesn't have time to really finish and begins again which results in more than one entry in the administration application.
I need to find a way to disable the Finish-button when the users clicks on it so I have time to finish my db operations.
How do I begin to solve this? I need some sort of script but how do I access the Finishbutton so I can disable it?
Very thankful for any help or suggestions!
/Dennis

<br />
Dim btn as button = Page.FindControl("FinishButtonId")<br />
btn.Enabled = False<br />
Hope this would help

I would like to put ASP software on my server, but I have heard that it has security issues. is this true
|
|
|
|
|
What ASP software do you mean? Do you mean the IIS web server that supports ASP, or some application developed using ASP?
What kind of security issues are you talking about?

You've 'heard' it has security issues ? Wow.
IIS without any patches on a machine with no firewall is probably not secure. Do you mean ASP, or ASP.NET ? Either way, doesn't matter too much, what is it you want to install, and why ? What security issues are you worried about ?

Plain vanilla ASP on IIS 4.0 did have security threats from CodeRed and NIMDA. However, subsequent ServicePacks and patches from Microsoft have filled the gap sufficiently.
It is upto the web administrator to suitably firewall the webserver and apply enough judicious security precautions.

Hi guys,
I have a database in SQL Server and I wanted to create a web interface in C#. I have 3 Listbox controls and a Textbox and two buttons for this. What I want to do is to select values from 3 Listbox controls and input some text in the textbox i.e year to display information on another page including all the information from listboxes too. I have no idea how to program this part. I have populated the 3 Listboxes from the database tables and I want to select some values from these listboxes and display information on another page. Could somebody help me in this regard. Below is the code I developed so far.
protected void Page_Load(object sender, EventArgs e)
{
// create the connection string and command string
string connectionString = "Server=.\\SQLEXPRESS;Database=NorthWind;Integrated Security=SSPI;";
string commandString = "Select * from Customers";
string commandString1 = "Select * from Orders";
string commandString2 = "Select * from Employees";
//pass the strings to the sql data adapter constructor
SqlDataAdapter dataAdapter = new SqlDataAdapter(commandString, connectionString);
SqlDataAdapter dataAdapter1 = new SqlDataAdapter(commandString1, connectionString);
SqlDataAdapter dataAdapter2 = new SqlDataAdapter(commandString2, connectionString);
SqlDataAdapter dataAdapter3 = new SqlDataAdapter(commandString2, connectionString);
// create a data set
DataSet dataSet = new DataSet();
// fill the dataset object
dataAdapter.Fill(dataSet, "Customers");
dataAdapter1.Fill(dataSet, "Orders");
dataAdapter2.Fill(dataSet, "Employees");
dataAdapter3.Fill(dataSet, "Products");
// for loop for customer table
foreach (DataRow dtrow in dataSet.Tables["Customers"].Rows)
{
ListBoxCustomers.Items.Add(dtrow["CustomerID"].ToString());
ListBoxCustomers.Items.Add(dtrow["City"].ToString());
ListBoxCustomers.Items.Add(dtrow["CompanyName"].ToString());
ListBoxCustomers.Items.Add(dtrow["ContactName"].ToString());
}
// for loop for Employees table
foreach (DataRow dtrow in dataSet.Tables["Employees"].Rows)
{
ListBoxEmployees.Items.Add(dtrow["EmployeeID"].ToString());
ListBoxEmployees.Items.Add(dtrow["LastName"].ToString());
ListBoxEmployees.Items.Add(dtrow["FirstName"].ToString());
}
// for loop for order table
foreach (DataRow dtrow in dataSet.Tables["Orders"].Rows)
{
ListBoxOrders.Items.Add(dtrow["OrderID"].ToString());
ListBoxOrders.Items.Add(dtrow["CustomerID"].ToString());
ListBoxOrders.Items.Add(dtrow["EmployeeID"].ToString());
}
And here is the Event Handler which I want to select values from the listboxes and a textbox and redirect the user to display relevant information on another page. Unfortunately I don't know how to code this part.
protected void BtnSubmit_Click(object sender, EventArgs e)
{
Response.Redirect("Default2.aspx"); // another page to display
}
I appreciate your help.
