I guess you need to tell us which line fails and show us the ASPX as well.

hello,
I have a department and an employee table. I populated a radio button list with all the department codes.
By default a Gridview will display all employee record. And, when I will select one department code on the radio button list, the GridView will only display employee record(s) with the same department code(s).
This is working fine with the ff:
protected void radioButtonList1_SelectedIndexChanged(object sender, EventArgs e)
{
SqlDataSource2.SelectParameters.Add("deptCode", radioButtonList1.SelectedValue);
SqlDataSource2.SelectCommand = "SELECT [iD], [firstName], [lastName], [dateOfBirth], [deptCode][position] FROM [F201] WHERE ([deptCode] = @deptCode)";
}
But, I think that, when there will be to many employee records, this will slow the loading. Is there any other way to display these record to a Gridview without re-querying to the table?
I am new to Asp.Net, any suggestion will be very much appreciated.

How many is too many?
Is your Gridview paginated? that could help in loading time. You could write sql stored procedure to help with the database performance too.

The only way is to load all the records and write javascript code to manupliate your gridview. But don't think this is going to be easy code.

Thanks man,
Yes the gridview is paged. I set it to 20. Anyway, I guess I am gonna be sticking to what i did for the main time, besides, it is not really that "many" records. I was just looking for any other alternatives to further speed up the apps
I guess I'll start digging for javascripts too
thanks again.

I can show my report (CR of VS 2005)in my development machine (Asp.Net 2.0 with C# code behind). But after deploying in my server, toolbar images are not displaying in the report.
It is showing as red color (X). I googled and tried some thing to rectify it. But, my problem is not solved so far. Any body can release me. It is urgent pls.

check the aspnet_client folder. Place it in the project root folder.
The miracle is this--the more we share, the more we have.

|

Actually, it is in c:\inetpub\wwwroot. But what i did is, I created one virtual directory under my project and give link into the aspnet_client. Even though it is not displaying
Balasubramanian K.

|

first be sure, it is only problem of aspnet_client folder. Type to copy and paste this folder into your project.

Yah..I've placed aspnet_client folder in to my project. Even though, the images are not displaying

Try to use server variable SERVER_NAME.

OK the thing is, this is not IIS. Its inbuilt web server of visual studio. that you cannot access from remote computer (other then your computer).
so you have to create a virual directory in your IIS. and copy the files from your project folder to that virtual directory. And then you can type.
i.e. http://10.10.15.57/< your virtual directory >/Login.aspx
to setup IIS you can either seach here or on google for the procedure, I think there is one article for setup IIS for asp.net website.

What dont you get?
"Compiler Error Message: BC30288: Local variable 'Classifieds' is already declared in the current block."

The error means what it says. Specifically:
1 - VB was designed for stupid people. It's not case sensitive. classifieds and Classifieds in VB would refer to the same thing. So would CLASSIFIEDS and cLassIfIEds.
2 - using case difference to create two different variables in the one block is even nastier than having a dataset called DataSet1. If you want your code to be unreadable, there are programs that do that for you AFTER you wrote the human readable version.
