Check your code here

C#

DataRow dr = ds.Tables[0].Rows[0];

You are retrieving only 1st row from the dataset. Please loop through the dataset like below:

C#

if(ds.Tables[0].Rows.Count > 0)
{
    foreach(DataRow dr in ds.Tables[0])
    {
        string strHeading = Convert.ToString(dr["divhtml_heading"]);
        string strContent = Convert.ToString(dr["divhtml_content"]);
    }
}

Also check the query you are running in the database if it really returns 6 records. I am asking this as you have mentioned a condition in your query,

SQL

select * from content_managment where page_id = 1

You've told it to only retrieve 1 record in your SQL statement...(unless you have 6 records with a page id of 1?)

SQL

select * from content_managment where page_id = 1

Also, you are only taking the first row from the results and doing something with that...

DataRow dr = ds.Tables[0].Rows[0];

You would need to iterate over the Rows collection, or bind to a grid - depends what you are trying to do really.

e.g.

C#

foreach(DataRow row in ds.Tables[0].Rows)
{
    // do something with each row in the results...
}
