how to fill datagridview with thousand of records quickly ?

On addition tk what members said, you can use OleDbDataReader class instead of Fill function. OleDbDataReader reads the data in forwarded direction whereas Fill function fetches all data first and then depicted in gridview, which will be faster processing. secondly, you can use pagination functionality as thousands of records aren't read by anyone at a time, show them as 20 records (as per requirement). Considering the points definitely have a overall decent pwrformance

Hi Ajit, let me know issue is fixed or not. There are basically 3 ways to display data in a DataGridView Create the rows manually in a loop, as you are currently doing: as you have noticed, it's very inefficient if you have a lot of data Use the DataGridView's virtual mode, as suggested by Jonathan in his comment: the DGV only creates as many rows as can be displayed, and dynamically changes their contents when the user scrolls. You need to handle the CellValueNeeded event to provide the required data to the DGV Use databinding: that's by far the easiest way. You just fill a DataTable with the data from the database using a DbDataAdapter, and you assign this DataTable to the DGV's DataSource property. The DGV can automatically create the columns (AutoGenerateColumns = true), or you can create them manually (you must set the DataPropertyName of the column to the name of the field you want to display). In databound mode, the DGV works like in virtual mode except that it takes care of fetching the data from the datasource, so you don't have anything to do. It's very efficient even for a large number of rows Thanks
