Please Help Datagrid Columns

I have a table called Computers with 8 colunms.

I have a select query that list out the Computer brand and the price.
what I want is that when I click on the computer brand then the respective information about this brand will be display in the same page or open a new page. I am using a datagrid, how do I make this work? or should I use other component like table.
Please helpIf you have unique Identifier for the Computerband table use it to create a hyperlink column in the datagrid. then pass the id as querystring. During the postback event read the Id get the details of the brand form from the id and then you can display that in formation in a panel below this grid.

Note;
1. AutoGenerateColumns property must be set to False
2. Manually Create DataGrid columns including the hyperlink column

Ex:

 <asp:DataGrid id="dg1" AutoGenerateColumns="False" runat="server">
 <asp:HyperLinkColumn Headertext="Brand Id" DataTextField="BrandId" DataNavigationUrlField="BrandId" DataNavigationUrlFormatString="ComputerBrands.aspx?brandId={0}" />
 <asp:BoundColumn DataField="ComputerBrandName" HeaderText="Brand Name"/>
 <!-- .... add other columns -->
 </asp:DataGrid

Thanks
Thank you Jay.

I still have som problem, I create a procedure that reads
Create Proc GetComputerID

@.ComputerID int

as
Select Computer,Price,CPU from Computers
Where ComputerID = @.ComputerID

I do not know where to pass the parameter in the grid, and I could not type computerID={0}
vb.net would not even allow me to run the application
I removed the where claus from my statement. But when I click on the hyperlink, nothing happens.
Here is the ASP code:
<asp:HyperLinkColumn Text="Computer" Target="_self" DataNavigateUrlField="ComputerID" DataNavigateUrlFormatString="UsedComputer.aspx?ComputerId={0}"
DataTextField="Computer" HeaderText="Computer" NavigateUrl="Computer"></asp:HyperLinkColumn>
<asp:BoundColumn DataField="Price" HeaderText="Price"></asp:BoundColumn>
<asp:BoundColumn Visible="False" DataField="ComputerID" HeaderText="ComputerID"></asp:BoundColumn>
</Columns>

please Help me find out a way!

I want a client to enter a 'key' in a textbox and click a button. then the entered value will be used to search a table in the MS-SQL database. The corresponding value found from that table will be used to search a second table. Data found from the second table will be bounded to the datagrid control at the page where the client entered the 'key'. What will be the way to achieve this? What will be the SQL command??

I'm not sure if I'm able to describe the problem. I'm a new user of ASP.NET. So please help.

Ishtiaque.

A stored procedure like this will work:

CREATE PROCEDUREdbo.Example
@.key1varchar(255)
AS
DECLARE@.key2varchar(255)
SELECT@.key2 = key2columnFROMTable1WHEREkey1column = @.key1
--The select below will return your results so you can bind to your grid:
SELECT*FROMTable2WHEREkey2column = @.key2

Thank you Sharbel_.

I made a stored procedure as you suggested and used it by a 'drag and drop' method in my webform. But as I mentioned I am a novice user of ASP.NET, could not utilize the sqlConnection or sqlCommand that resulted of doing so. Would you please let me know how to do so?

Thanks in advance.

Hi,

using System.Data.SqlClient; at the top in the .cs file

Create the connection and the command objects in the page_load or in the button click as

SqlConnection sqlcn =new SqlConnection(connectionString);

sqlcn.Open();

//creating and initialising a command object

SqlCommand sqlcm =new SqlCommand();

sqlcm.Connection = sqlcn;

sqlcm.CommandType = CommandType.StoredProcedure;

sqlcm.CommandText = StoredProcedure name;

sqlcm.ExecuteNonQuery();

HTH.

please help me to solve my provblem..its very urgent

i have a button in my webform. whenever i click that button it should display the crystal report designer window so that the end user can design his own report...
i don't know how to display crystal report designer window at runtime in asp.net.please help me...

please please help me...its very very urgent

Hello Niranjana,

A CrystalReportViewer needs a CrystalReportSource in order to function. So, in the scenario you outlined above, you'd need to dynamically add both to the page. In VB.NET, this would look something like the following:

 Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click Dim crs As New CrystalDecisions.Web.CrystalReportSource crs.ID = "CrystalReportSource1" crs.Report.FileName = "CrystalReport1.rpt" form1.Controls.Add(crs) Dim crv As New CrystalDecisions.Web.CrystalReportViewer crv.Height = New Unit("200px") crv.Width = New Unit("200px") crv.AutoDataBind = True crv.ReportSourceID = "CrystalReportSource1" form1.Controls.Add(crv) End Sub

HTH,
Clay

sir,

thank you so much for ur information.

but my problem is different. I need to design the crystal report at runtime... ie one end user be able to design his crystal report.. ie adding fields ,formatting crystal reports all those things...

if u have any idea please help me sir

thanks & regards

nisha

Hi nish,

I dont whether its possible to enable the users to design his own reports... But try the below logic...

1. You need to list all of the fileds available in the reports...

2. Create the query which fetches the data from the table for the fields selected by the user and empty for unselected fileds. (initially you need to design the reports with all the fields)

3. suppress the fields in crystal reports if the field value is empty.

I hope the above will help you...

that i can do sir,i have already listed all the fields of a table in a listbox and use that to create crystal report...

my problem is really different...the end user should able to design his own crystal reports.

at runtime the designer should come. can we use any Report Designer Component(RDC) in asp.net...i am not getting an exact idea from net also. if u can please help me sir...

Hi nish,

Sorry I dont know whether its possible or not... I think its not available in Crystal reports... but may be in some other third party report tools...

anyway..thank you sir..

please help me!

hi all,
i wanna create a page which has two parts.
in the first part,i have header and menus and logo...
when i click on any thing in the firs part it shows the result
in the second part without any refresh in page.
could you please help me?
i would be apprecited any suggestion.

thanks

Even if you did do something like have panels and just toggled the visibility, it would still refresh the page because of postback

So I'm not sure if theres any method to change whats being displayed on an ASP.NET page without refresh from a postback.

Hi,
It seems you'll need to do all that in JavaScript, as there is presently no way to run .net languages on the client browser.
You could cheat a bit and put the right side content in an IFRAME sothat you could reload that one only. You'll need to get your handsdirty with even more javascript for this one, however.
John

two words. Java Script.

You can create <div></div> regions and set the display value to none or block. here is a start for you. you will have to create a button to fire the javascipt.

<script language="javascript">

function showView(divID){

document.getElementById('span1').style.dispaly = 'none';

document.getElementById('span2').style.display = 'none';

document.getElementById(divID).style.display = 'block';

}

<html>

<div id="span1" style="DISPLAY: none">Hello</div>

<div id="span2" style="DISPLAY: block">Good Bye</div>

You could also use IFRAMEs. When the user clicks on the selectedoption, it loads the selected page in the IFRAME. All you have to do isadd a target="<iframeName>" attribute to the anchor. Thecontainer page never needs to refresh.
Also,Javascript is one word.
Regards,
Sam

I stand corrected.

Hi All,
thanks for your suggestions,really i didn't know how to start?
all of your solutions were useful and i used them
AGAIN MANY MANY THANKS GUYS

You cannot set the target from the server side. You have to set the target in
the HTML on the first render.

Check the HTML ref, but IIRC its just target="name" for the frame. I know
this is for separate Windows - I cannot remember offhand if frames use Target
too or if there is a separate key word. Its been a long time since I needed
frames since I use partial updates instead because they are more flexible.
