Good Day friends

I would like to take this chance and thank you guys for helping me resolve the Current Problem. I was using Infragestic Controls and had a hard time using them. But with people like you online I made it. You are stars and you deserve ratings.

Thank you,

IsPostBack will return TRUE when the page has posted back. It will return FALSE if it is a normal refresh.

It will call as it is not doing any postback.

I am not clear with that. Do you think the home page details will persist even if you move to other pages?

Data is changing while refreshing or clicking this link. i don't want to change the data once the page is loaded. it should change only next time open the website.

It looks like you are not clear with the web concepts. Web is stateless. So each time a page is requested, it has to load completely. You can use caching to persist the data which you don't want to load often.

Not SQL, but you can use DataTable.Select[^] method with a filter criteria.

retrieving a sql results with a specific Id using Rank and Partition

Hi

What springs to mind....

The first thing I would look at is returning two result sets (presumably your first would have one row in it and your second would have many, excluding the unique row you've already selected, ordered by create date) from your store proc. Then using a ADO.Net DataReader I would merge the two result sets in code.

Here's some pseudo with some c#

    // create return object (a list) here

    using ( SqlDataReader reader = command.ExecuteReader( ) )
    {
        // read first doc

        if ( reader.Read( ) )
        {
            // add data to a DTO, or business object then add to results list
        }

        // move to next result set and read the other docs

        reader.NextResult();

        while ( reader.Read( ) )
        {
            // add data to a DTO, or business object then add to results list
        }
    }
    // return list - the merged results

This is still only one stored proc call; one trip across the wire (not that two trips in this case would make the slightest bit of difference).

Has this helped?

Events in a UserControl

Good Day All

Am using a Infragistic Ultragrid Control and in the Control there is no event RowDataBound, So i decided to add it. I right Clicked on the Control and went to Properties and clicked at the lightning sign for events and double clicked "DataBound" event and next to it i started coding my event like this

protected void ultraGridCycles_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        //We're only interested in rows that contain data

        //Get a reference to the data used  to databound the row
        DataRowView drv = (DataRowView)e.Row.DataItem;
        if (Convert.ToString(drv["1"]) == "1")
        {
            e.Row.Font.Bold = true;
            e.Row.ForeColor = System.Drawing.Color.Gold;
        }
    }

}

The Compiler did not complain. Now i want to use this event in the like in MS Gridview. How do i get that event to be Fired ?

Thank you
