To append data in an existing GridView control in ASP.NET, you can follow these steps: Get the data you want to append to the GridView . This could be a single row or multiple rows of data. Create a new DataTable object and add the columns that match the columns in your GridView . Add the new data to the DataTable object as rows. Merge the new DataTable with the existing DataTable of the GridView . Bind the merged DataTable to the GridView . Example: // Get the new data to append DataTable newDataTable = GetNewData(); // Create a new DataTable with matching columns DataTable existingDataTable = ((DataView)gridView.DataSource).Table; DataTable mergedDataTable = existingDataTable.Clone(); // Add new data to the DataTable foreach (DataRow newRow in newDataTable.Rows) { mergedDataTable.Rows.Add(newRow.ItemArray); } // Merge the new DataTable with the existing DataTable foreach (DataRow existingRow in existingDataTable.Rows) { mergedDataTable.ImportRow(existingRow); } // Bind the merged DataTable to the GridView gridView.DataSource = mergedDataTable; gridView.DataBind();
